protecting SSH Servers with Single Packet Authorization | killexams.com Real Questions and Pass4sure dumps

closing month, in the first of a two-half collection, I described the thought behind the subsequent technology in passive authentication technologies called Single Packet Authorization (SPA). this text receives away from idea and concentrates on the purposeful application of SPA with fwknop and iptables to protect SSHD from reconnaissance and assault. With this setup on a Linux system, no one could be capable of inform that SSHD is even listening below an nmap scan, and handiest authenticated and authorized purchasers can be in a position to communicate with SSHD.

To start, we require some tips about configuration and community architecture. this text assumes you've got installed the newest version of fwknop (1.0.1 at the time of this writing) on the identical system where SSHD and iptables are operating. that you may download fwknop from www.cipherdyne.org/fwknop and installation either from the supply tar archive with the aid of operating the set up.pl script or via the RPM for RPM-based Linux distributions.

network structure

The fundamental network depicted in determine 1 illustrates our setup. The fwknop client is accomplished on the host labeled spa_client (15.1.1.1), and the fwknop server (along with iptables) runs on the system labeled spa_server (sixteen.2.2.2). A malicious gadget is labeled attacker (18.3.three.3), which is able to sniff all traffic between the spa_client and spa_server programs.

determine 1. pattern scenario the place you employ SPA to protect SSH Communications

Default-Drop iptables policy

The spa_client system has the IP handle 15.1.1.1, and the spa_server system has the IP tackle sixteen.2.2.2. On the spa_server gadget, iptables is configured to give fundamental connectivity features for the internal network (192.168.10.0/24) and to log and drop all makes an attempt (via the iptables LOG and DROP aims) from the external network to hook up with any service on the firewall itself. This policy is fairly simplistic, and it's intended to exhibit best that the firewall doesn't promote any capabilities (together with SSHD) under an nmap scan. Any critical deployment of iptables for a real community could be greatly extra complicated. One vital function to observe, although, is that the connection tracking facilities offered by way of Netfilter are used to retain state within the iptables policy. The fruits is that connections initiated throughout the firewall (by the use of the forward chain) and to the firewall (by way of the input chain) continue to be open with out extra accept guidelines to allow packets required to retain the connections based (comparable to TCP acknowledgements etc). The iptables coverage is constructed with the following basic firewall.sh script:

[spa_server]# cat firewall.sh #!/bin/sh IPTABLES=/sbin/iptables $IPTABLES -F $IPTABLES -F -t nat $IPTABLES -X $IPTABLES -A enter -m state --state ↪based,linked -j accept $IPTABLES -A forward -m state --state ↪established,linked -j settle for $IPTABLES -t nat -A POSTROUTING -s ↪192.168.10.0/24 -o eth0 -j MASQUERADE $IPTABLES -A enter -i ! lo -j LOG --log-prefix ↪"DROP " $IPTABLES -A input -i ! lo -j DROP $IPTABLES -A ahead -i ! lo -j LOG --log-prefix ↪"DROP " $IPTABLES -A forward -i ! lo -j DROP echo 1 > /proc/sys/web/ipv4/ip_forward echo "[+] iptables coverage activated" exit [spa_server]# ./firewall.sh [+] iptables policy activated

With iptables active, it is time to see what far flung entry we may have. From the spa_client device, we use nmap to see if SSHD is obtainable on the spa_server device:

[spa_client]$ nmap -P0 -sT -p 22 sixteen.2.2.2 beginning Nmap four.01 ( http://www.insecure.org/nmap/ ) at 2007-02-09 23:55 EST interesting ports on 16.2.2.2: PORT STATE service 22/tcp filtered ssh Nmap finished: 1 IP address (1 host up) scanned in 12.009 seconds

As anticipated, iptables is blocking all makes an attempt to communicate with SSHD, and the remaining ports (both TCP and UDP) are in a similar fashion covered by means of the iptables coverage. It doesn't be counted if an attacker has a nil-day make the most for the selected edition of OpenSSH it's deployed on the spa_server equipment; all makes an attempt to talk up the stack are being blocked by means of iptables.

fwknop SPA Configuration

confident that iptables is retaining the local community with a Draconian stance, it is time to configure the fwknop server dæmon (fwknopd) on the spa_server system. The file /and so on/fwknop/fwknop.conf controls important configuration parameters, such because the interface on which fwknopd sniffs traffic via libpcap, the e mail address(es) to which fwknopd sends informational signals and the pcap filter commentary designed to smell SPA packets off the wire. by default, fwknop sends SPA packets over UDP port 62201, so the pcap filter observation in /and so forth/fwknop/fwknop.conf is set to udp port 62201 by default. youngsters, SPA packets can also be sent over any port and protocol (even over ICMP), however the filter statement would need to be up to date to address SPA communications over different port/protocols. more counsel will also be found in the fwknop man page. although the defaults during this file usually make sense for many deployments, you may wish to tweak the PCAP_INTF and EMAIL_ADDRESSES variables for your particular setup.

The /and many others/fwknop/entry.conf file is probably the most essential fwknopd configuration file—it manages the encryption keys and access control rights used to validate SPA packets from fwknop consumers. right here entry.conf file is used for the remainder of this article:

[spa_server]# cat /and many others/fwknop/access.conf source: ANY; OPEN_PORTS: tcp/22; FW_ACCESS_TIMEOUT: 30; KEY: LJ07p2rbga; GPG_DECRYPT_ID: ABCD1234; GPG_DECRYPT_PW: p2atc1l30p; GPG_REMOTE_ID: 5678DEFG; GPG_HOME_DIR: /root/.gnupg;

The supply variable defines the IP addresses from which fwknopd accepts SPA packets. The value ANY proven above is a wild card to investigate SPA packets from any IP address, nonetheless it will also be restricted to selected IP addresses or subnets, and comma-separated lists are supported (for example, 192.168.10.0/24, 15.1.1.1). The OPEN_PORTS variable informs fwknopd about the set of ports that should still be opened upon receiving a valid SPA packet; in this case, fwknopd will open TCP port 22.

although now not shown above, fwknopd will also be configured to permit the fwknop client to dictate the set of ports to open with the aid of including the PERMIT_CLIENT_PORTS variable and atmosphere it to Y. FW_ACCESS_TIMEOUT specifies the length of time that an settle for rule is delivered to the iptables coverage to permit the site visitors described by the OPEN_PORTS variable. since the iptables coverage in the firewall.sh script above makes use of the connection monitoring capabilities offered with the aid of Netfilter, an SSH connection will remain centered after the initial settle for rule is deleted by using fwknopd.

The closing variables outline parameters for the encryption and decryption of SPA packets. this text illustrates the usage of both symmetric and uneven ciphers, however only one encryption style is required by using fwknop.

the entire GPG_* variables can be unnoticed if there's a KEY variable and vice versa. the key variable defines a shared key between the fwknop client and fwknopd server. This key's used to encrypt/decrypt the SPA packet with the Rijndael symmetric block cipher (see substances). For asymmetric encryption, GPG_DECRYPT_ID defines the local fwknopd server GnuPG key identification. This secret's used by way of the fwknop client to encrypt SPA packets by means of an encryption algorithm supported with the aid of GnuPG (such because the ElGamal cipher).

GPG_DECRYPT_PW is the decryption password linked to the fwknopd server key. as a result of this password is placed inside the entry.conf file in clear textual content, it isn't advised to make use of a effective GnuPG key for the server; a committed key should still be generated for the goal of decrypting SPA packets. The fwknop consumers signal SPA packets with a GnuPG key on the native key ring, and the password is offered by means of the consumer from the command line and under no circumstances stored within a file (as we will see under). hence, any GnuPG key can be used through the fwknop customer; even a beneficial key used for encrypting delicate electronic mail communications, as an example.

The GPG_REMOTE_ID variable defines a list of key IDs that the fwknopd server will settle for. Any SPA packet encrypted with the fwknopd server public key need to be signed with a personal key particular by means of the GPG_REMOTE_ID variable. This enables fwknopd to avert the set of people who can profit access to a included provider (SSHD in our case) by the use of a cryptographically robust mechanism. guidance for growing GnuPG keys for use with fwknop may also be found at www.cipherdyne.org/fwknop/docs/gpghowto.html.

With the /etc/fwknop/entry.conf file developed, it is time to birth fwknopd on the spa_server device and put fwknop to work for us:

[spa_server]# /and so forth/init.d/fwknop beginning * starting fwknop ... [ ok ]

SPA by the use of Symmetric Encryption

On the spa_client system, we use fwknop to construct an SPA packet encrypted by the use of Rijndael and send it on its technique to the spa_server system. We need entry to SSHD, and the -A argument under encodes the desired entry within the SPA packet. The -w argument resolves the IP address of the client gadget by querying http://www.whatismyip.com (this is effective if the fwknop customer is behind a NAT gadget), the -okay argument is the IP address of the vacation spot SPA server, and -v runs in verbose mode on the way to view the raw packet information:

[spa_client]$ fwknop -A tcp/22 -w -ok sixteen.2.2.2 -v [+] starting fwknop in customer mode. Resolving exterior IP by the use of: http://www.whatismyip.com/ obtained exterior tackle: 15.1.1.1 [+] Enter an encryption key. This key must fit a key in the file /and so on/fwknop/access.conf on the far flung system. Encryption Key: [+] constructing encrypted single-packet authorization (SPA) message... [+] Packet fields: Random information: 7764880827899123 Username: mbr Timestamp: 1171133745 version: 1.0.1 action: 1 (access mode) entry: 15.1.1.1,tcp/22 MD5 sum: yzxKgnAxwUA5M2YhI8NTFQ [+] Packet records: U2FsdGVkX1+BvzxXj5Zv6gvfCFXwJ+iJGKPqe2whdYzyigkerSp \ 2WtvON/xTd8t6V6saxbg1v4zsK+YNt53BE8EInxVCgpD7y/gEBI \ g8sd+AvU1ekQh9vwJJduseVxDxjmAHx3oNnClo2wckBqd8zA [+] Sending one hundred fifty byte message to 16.2.2.2 over udp/62201...

As that you may see from the Packet information section above, the SPA packet is a completely unintelligible blob of encrypted information. On the spa_server system, here syslog message is generated indicating that an settle for rule has been delivered for the source IP (15.1.1.1) that generated the SPA packet. observe that the source IP is put within the SPA packet via the fwknop client. in this case, the SPA packet was not spoofed, so the true source tackle and the supply address embedded in the SPA packet match. SPA packets can be spoofed via fwknop with the --Spoof-src command-line argument (requires root):

Feb 10 13:fifty five:44 spa_server fwknopd: got valid Rijndael \ encrypted packet from: 15.1.1.1, faraway consumer: mbr Feb 10 13:fifty five:44 spa_server fwknopd: including FWKNOP_INPUT accept \ rule for 15.1.1.1 -> tcp/22 (30 seconds)

So, for 30 seconds after sending the SPA packet, the iptables policy on the spa_server allows for the spa_client system to set up an SSH session:

[spa_client]$ ssh -l mbr 16.2.2.2 mbr@spa_server's password:

After 30 seconds has expired, knoptm (a dæmon responsible for deleting iptables rules brought by fwknopd to the iptables policy) deletes the settle for rule and writes here messages to syslog:

Feb 10 13:fifty two:17 spa_server knoptm: eliminated iptables \ FWKNOP_INPUT accept rule for 15.1.1.1 -> tcp/22, \ 30 2d timeout handed

Our SSH session remains established after the settle for rule is deleted on account of the state tracking suggestions within the iptables coverage (see the firewall.sh script above). These guidelines allow packets which are part of an established TCP connection to circulate unimpeded.

SPA via asymmetric Encryption

to make use of GnuPG to encrypt and sign an SPA packet, that you can execute the fwknop command below. during this case, the key id of the fwknopd server is special on the command line with the --gpg-recipient argument, and the key id used to sign the SPA packet is given with the --gpg-signing-key argument (the output under has been abbreviated):

[spa_client]$ fwknop -A tcp/22 --gpg-recipient ABCD1234 \ --gpg-signing-key 5678DEFG -w -ok sixteen.2.2.2 [+] Sending 1010 byte message to sixteen.2.2.2 over udp/62201

As that you would be able to see, the size of the utility element of the SPA packet has accelerated to greater than 1,000 bytes, whereas it changed into most effective a hundred and fifty bytes for the Rijndael example. here's because the key size of GnuPG keys (during this case 2,048 bits) and the features of asymmetric ciphers tend to inflate the dimension of small chunks of statistics after being encrypted. There is not any strict correspondence between the measurement of clear-text and cipher-text statistics as in block ciphers reminiscent of Rijndael.

again, on the spa_server equipment, fwknop provides the settle for rule for us. This time fwknopd experiences that the SPA packet is encrypted with GnuPG, and that a legitimate signature for the required key id 5678DEFG is discovered:

Feb 10 14:38:26 spa_server fwknopd: acquired valid GnuPG encrypted packet (signed with required key identification: "5678DEFG") from: 15.1.1.1, far off consumer: mbr Feb 10 14:38:26 spa_server fwknopd: including FWKNOP_INPUT accept rule for 15.1.1.1 -> tcp/22 (30 seconds)

Thwarting a Replay attack

believe that the SPA packet from the first illustration above was sniffed off the wire en route via a artful particular person on the device labeled attacker in the network diagram in figure 1. The SPA packet always can also be placed returned on the wire as a way to benefit the identical entry as the common packet—here is referred to as a replay attack. There are several tips on how to acquire the packet statistics and replay it. one of the vital ordinary is to use tcpdump to put in writing a pcap file (in this case tcpdump -i eth0 -l -nn -s 0 -w SPA.pcap port 62201 would work) and then use tcpreplay (see tcpreplay.synfin.internet/trac) to copy the SPA packet lower back onto the wire. one other method, after the packet has been captured, is to make use of the echo command along with netcat:

[attacker]$ echo "U2FsdGVkX1+BvzxXj5Zv6gvfCFXwJ+iJGKP \ qe2whdYzyigkerSp2WtvON/xTd8t6V6saxbg1v4zsK+YNt53BE8EI \ nxVCgpD7y/gEBIg8sd+AvU1ekQh9vwJJduseVx \ DxjmAHx3oNnClo2wckBqd8zA" |nc -u 16.2.2.2 62201

On the fwknopd server, the replica SPA packet is monitored, but because the MD5 sum suits that of the long-established SPA packet, no access is granted, and here message is written to syslog on the spa_server equipment:

Feb 10 14:14:24 spa_server fwknopd: attempted \ message replay from: 18.3.three.3

Conclusion

Single Packet Authorization gives an further layer of safety for services similar to SSHD, and this layer strikes at the first step that an attacker must accomplish when attempting to compromise a gadget: reconnaissance. by using iptables in a default-drop stance and fwknop to sniff the wire for in particular developed (this is, encrypted and non-replayed) packets, it is elaborate even to inform that a service is listening, not to mention talk with it. The fruits is that it is significantly harder to make the most any vulnerabilities a protected service could have.

    review: The Enterasys NAC answer is a combination of hardware and utility that provides NAC features in each Enterasys and non-Enterasys networks. Enterasys NAC begins with a NAC supervisor, a management equipment developed on-precise of the Enterasys NetSight supervisor platform. NAC supervisor is used to control NAC appliances, which themselves are available in two varieties: NAC Controller home equipment, which might be in-line NAC enforcement instruments, and NAC Gateway home equipment, which are nearly RADIUS servers with very NAC-certain characteristic units.

    NAC: What went incorrect?

    We tested Enterasys NAC in its area-enforcement mode, using a single NAC manager and single NAC Gateway to handle our Cisco, HP and Juniper switches. Enterasys also sent us one of its switches, which we threw into the combine. Our trying out concentrated on 802.1X-class NAC deployments, and the Enterasys NAC become each convenient to installation and performed well on our heterogeneous community.

    As we expected with any mature NAC product, we found our justifiable share of ambiguities and design flaws in the management equipment. still, the NAC manager ended up being relatively effortless to make use of.

    Enterasys has a vast product line, including captive portal functionality, guest registration, and the skill to settle for exterior security inputs (akin to from its Dragon IDS product) into the NAC resolution-making manner.

    We additionally discovered some principally based considering in the Enterasys NAC product. as an example, Enterasys NAC makes use of DiffServ packet tagging and coverage-primarily based routing to drive unauthenticated users to their captive portal, a extremely clever answer that avoids the issues linked to changing user VLANs on the fly.

    most likely, Enterasys NAC works most suitable with their personal switches, which have a fairly sophisticated access manage list characteristic built-in, however we have been in a position to push each VLAN and access control lists to all of the non-Enterasys switches in our network very quite simply.As a extremely powerful product, Enterasys NAC also includes the normal endpoint security checking elements. both an on-network scan the use of Saint agency’s community scanner, and an on-gadget scan the usage of the Enterasys agent, are supported.

    Enterasys has performed an excellent job making certain that its NAC product works very smartly in non-Enterasys networks. as a result of Enterasys NAC has both in-line and facet-enforcement technologies in a single product line, we think that here's a definite short-record for any 802.1X-primarily based NAC deployment.

    Protecting SSH Servers with Single Packet Authorization | killexams.com real questions and Pass4sure dumps

    Last month, in the first of a two-part series, I described the theory behind the next generation in passive authentication technologies called Single Packet Authorization (SPA). This article gets away from theory and concentrates on the practical application of SPA with fwknop and iptables to protect SSHD from reconnaissance and attack. With this setup on a Linux system, no one will be able to tell that SSHD is even listening under an nmap scan, and only authenticated and authorized clients will be able to communicate with SSHD.

    To begin, we require some information about configuration and network architecture. This article assumes you have installed the latest version of fwknop (1.0.1 at the time of this writing) on the same system where SSHD and iptables are running. You can download fwknop from www.cipherdyne.org/fwknop and install either from the source tar archive by running the install.pl script or via the RPM for RPM-based Linux distributions.

    Network Architecture

    The basic network depicted in Figure 1 illustrates our setup. The fwknop client is executed on the host labeled spa_client (15.1.1.1), and the fwknop server (along with iptables) runs on the system labeled spa_server (16.2.2.2). A malicious system is labeled attacker (18.3.3.3), which is able to sniff all traffic between the spa_client and spa_server systems.

    Figure 1. Sample Scenario Where You Use SPA to Protect SSH Communications

    Default-Drop iptables Policy

    The spa_client system has the IP address 15.1.1.1, and the spa_server system has the IP address 16.2.2.2. On the spa_server system, iptables is configured to provide basic connectivity services for the internal network (192.168.10.0/24) and to log and drop all attempts (via the iptables LOG and DROP targets) from the external network to connect to any service on the firewall itself. This policy is quite simplistic, and it is meant to show only that the firewall does not advertise any services (including SSHD) under an nmap scan. Any serious deployment of iptables for a real network would be significantly more complicated. One important feature to note, however, is that the connection tracking facilities provided by Netfilter are used to keep state in the iptables policy. The end result is that connections initiated through the firewall (via the FORWARD chain) and to the firewall (via the INPUT chain) remain open without additional ACCEPT rules to allow packets required to keep the connections established (such as TCP acknowledgements and the like). The iptables policy is built with the following basic firewall.sh script:

    [spa_server]# cat firewall.sh #!/bin/sh IPTABLES=/sbin/iptables $IPTABLES -F $IPTABLES -F -t nat $IPTABLES -X $IPTABLES -A INPUT -m state --state ↪ESTABLISHED,RELATED -j ACCEPT $IPTABLES -A FORWARD -m state --state ↪ESTABLISHED,RELATED -j ACCEPT $IPTABLES -t nat -A POSTROUTING -s ↪192.168.10.0/24 -o eth0 -j MASQUERADE $IPTABLES -A INPUT -i ! lo -j LOG --log-prefix ↪"DROP " $IPTABLES -A INPUT -i ! lo -j DROP $IPTABLES -A FORWARD -i ! lo -j LOG --log-prefix ↪"DROP " $IPTABLES -A FORWARD -i ! lo -j DROP echo 1 > /proc/sys/net/ipv4/ip_forward echo "[+] iptables policy activated" exit [spa_server]# ./firewall.sh [+] iptables policy activated

    With iptables active, it is time to see what remote access we might have. From the spa_client system, we use nmap to see if SSHD is accessible on the spa_server system:

    [spa_client]$ nmap -P0 -sT -p 22 16.2.2.2 Starting Nmap 4.01 ( http://www.insecure.org/nmap/ ) at 2007-02-09 23:55 EST Interesting ports on 16.2.2.2: PORT STATE SERVICE 22/tcp filtered ssh Nmap finished: 1 IP address (1 host up) scanned in 12.009 seconds

    As expected, iptables is blocking all attempts to communicate with SSHD, and the remaining ports (both TCP and UDP) are similarly protected by the iptables policy. It does not matter if an attacker has a zero-day exploit for the particular version of OpenSSH that is deployed on the spa_server system; all attempts to communicate up the stack are being blocked by iptables.

    fwknop SPA Configuration

    Confident that iptables is protecting the local network with a Draconian stance, it is time to configure the fwknop server dæmon (fwknopd) on the spa_server system. The file /etc/fwknop/fwknop.conf controls important configuration parameters, such as the interface on which fwknopd sniffs traffic via libpcap, the e-mail address(es) to which fwknopd sends informational alerts and the pcap filter statement designed to sniff SPA packets off the wire. By default, fwknop sends SPA packets over UDP port 62201, so the pcap filter statement in /etc/fwknop/fwknop.conf is set to udp port 62201 by default. However, SPA packets can be sent over any port and protocol (even over ICMP), but the filter statement would need to be updated to handle SPA communications over other port/protocols. More information can be found in the fwknop man page. Although the defaults in this file usually make sense for most deployments, you may need to tweak the PCAP_INTF and EMAIL_ADDRESSES variables for your particular setup.

    The /etc/fwknop/access.conf file is the most important fwknopd configuration file—it manages the encryption keys and access control rights used to validate SPA packets from fwknop clients. The following access.conf file is used for the remainder of this article:

    [spa_server]# cat /etc/fwknop/access.conf SOURCE: ANY; OPEN_PORTS: tcp/22; FW_ACCESS_TIMEOUT: 30; KEY: LJ07p2rbga; GPG_DECRYPT_ID: ABCD1234; GPG_DECRYPT_PW: p2atc1l30p; GPG_REMOTE_ID: 5678DEFG; GPG_HOME_DIR: /root/.gnupg;

    The SOURCE variable defines the IP addresses from which fwknopd accepts SPA packets. The value ANY shown above is a wild card to examine SPA packets from any IP address, but it can be restricted to specific IP addresses or subnets, and comma-separated lists are supported (for example, 192.168.10.0/24, 15.1.1.1). The OPEN_PORTS variable informs fwknopd about the set of ports that should be opened upon receiving a valid SPA packet; in this case, fwknopd will open TCP port 22.

    Although not shown above, fwknopd can be configured to allow the fwknop client to dictate the set of ports to open by including the PERMIT_CLIENT_PORTS variable and setting it to Y. FW_ACCESS_TIMEOUT specifies the length of time that an ACCEPT rule is added to the iptables policy to allow the traffic defined by the OPEN_PORTS variable. Because the iptables policy in the firewall.sh script above makes use of the connection tracking capabilities provided by Netfilter, an SSH connection will remain established after the initial ACCEPT rule is deleted by fwknopd.

    The remaining variables define parameters for the encryption and decryption of SPA packets. This article illustrates the usage of both symmetric and asymmetric ciphers, but only one encryption style is required by fwknop.

    All of the GPG_* variables can be omitted if there is a KEY variable and vice versa. The KEY variable defines a shared key between the fwknop client and fwknopd server. This key is used to encrypt/decrypt the SPA packet with the Rijndael symmetric block cipher (see Resources). For asymmetric encryption, GPG_DECRYPT_ID defines the local fwknopd server GnuPG key ID. This key is used by the fwknop client to encrypt SPA packets via an encryption algorithm supported by GnuPG (such as the ElGamal cipher).

    GPG_DECRYPT_PW is the decryption password associated with the fwknopd server key. Because this password is placed within the access.conf file in clear text, it is not recommended to use a valuable GnuPG key for the server; a dedicated key should be generated for the purpose of decrypting SPA packets. The fwknop clients sign SPA packets with a GnuPG key on the local key ring, and the password is supplied by the user from the command line and never stored within a file (as we will see below). Hence, any GnuPG key can be used by the fwknop client; even a valuable key used for encrypting sensitive e-mail communications, for example.

    The GPG_REMOTE_ID variable defines a list of key IDs that the fwknopd server will accept. Any SPA packet encrypted with the fwknopd server public key must be signed with a private key specified by the GPG_REMOTE_ID variable. This allows fwknopd to restrict the set of people who can gain access to a protected service (SSHD in our case) via a cryptographically strong mechanism. Instructions for creating GnuPG keys for use with fwknop can be found at www.cipherdyne.org/fwknop/docs/gpghowto.html.

    With the /etc/fwknop/access.conf file built, it is time to start fwknopd on the spa_server system and put fwknop to work for us:

    [spa_server]# /etc/init.d/fwknop start * Starting fwknop ... [ ok ]

    SPA via Symmetric Encryption

    On the spa_client system, we use fwknop to build an SPA packet encrypted via Rijndael and send it on its way to the spa_server system. We want access to SSHD, and the -A argument below encodes the desired access within the SPA packet. The -w argument resolves the IP address of the client system by querying http://www.whatismyip.com (this is useful if the fwknop client is behind a NAT device), the -k argument is the IP address of the destination SPA server, and -v runs in verbose mode so we can view the raw packet data:

    [spa_client]$ fwknop -A tcp/22 -w -k 16.2.2.2 -v [+] Starting fwknop in client mode. Resolving external IP via: http://www.whatismyip.com/ Got external address: 15.1.1.1 [+] Enter an encryption key. This key must match a key in the file /etc/fwknop/access.conf on the remote system. Encryption Key: [+] Building encrypted single-packet authorization (SPA) message... [+] Packet fields: Random data: 7764880827899123 Username: mbr Timestamp: 1171133745 Version: 1.0.1 Action: 1 (access mode) Access: 15.1.1.1,tcp/22 MD5 sum: yzxKgnAxwUA5M2YhI8NTFQ [+] Packet data: U2FsdGVkX1+BvzxXj5Zv6gvfCFXwJ+iJGKPqe2whdYzyigkerSp \ 2WtvON/xTd8t6V6saxbg1v4zsK+YNt53BE8EInxVCgpD7y/gEBI \ g8sd+AvU1ekQh9vwJJduseVxDxjmAHx3oNnClo2wckBqd8zA [+] Sending 150 byte message to 16.2.2.2 over udp/62201...

    As you can see from the Packet data section above, the SPA packet is a completely unintelligible blob of encrypted data. On the spa_server system, the following syslog message is generated indicating that an ACCEPT rule has been added for the source IP (15.1.1.1) that generated the SPA packet. Note that the source IP is put within the SPA packet by the fwknop client. In this case, the SPA packet was not spoofed, so the real source address and the source address embedded in the SPA packet match. SPA packets can be spoofed by fwknop with the --Spoof-src command-line argument (requires root):

    Feb 10 13:55:44 spa_server fwknopd: received valid Rijndael \ encrypted packet from: 15.1.1.1, remote user: mbr Feb 10 13:55:44 spa_server fwknopd: adding FWKNOP_INPUT ACCEPT \ rule for 15.1.1.1 -> tcp/22 (30 seconds)

    So, for 30 seconds after sending the SPA packet, the iptables policy on the spa_server allows the spa_client system to establish an SSH session:

    [spa_client]$ ssh -l mbr 16.2.2.2 mbr@spa_server's password:

    After 30 seconds has expired, knoptm (a dæmon responsible for deleting iptables rules added by fwknopd to the iptables policy) deletes the ACCEPT rule and writes the following messages to syslog:

    Feb 10 13:52:17 spa_server knoptm: removed iptables \ FWKNOP_INPUT ACCEPT rule for 15.1.1.1 -> tcp/22, \ 30 second timeout exceeded

    Our SSH session remains established after the ACCEPT rule is deleted because of the state tracking rules in the iptables policy (see the firewall.sh script above). These rules allow packets that are part of an established TCP connection to pass unimpeded.

    SPA via Asymmetric Encryption

    To use GnuPG to encrypt and sign an SPA packet, you can execute the fwknop command below. In this case, the key ID of the fwknopd server is specified on the command line with the --gpg-recipient argument, and the key ID used to sign the SPA packet is given with the --gpg-signing-key argument (the output below has been abbreviated):

    [spa_client]$ fwknop -A tcp/22 --gpg-recipient ABCD1234 \ --gpg-signing-key 5678DEFG -w -k 16.2.2.2 [+] Sending 1010 byte message to 16.2.2.2 over udp/62201

    As you can see, the length of the application portion of the SPA packet has increased to more than 1,000 bytes, whereas it was only 150 bytes for the Rijndael example. This is because the key length of GnuPG keys (in this case 2,048 bits) and the characteristics of asymmetric ciphers tend to inflate the size of small chunks of data after being encrypted. There is no strict correspondence between the size of clear-text and cipher-text data as in block ciphers such as Rijndael.

    Again, on the spa_server system, fwknop adds the ACCEPT rule for us. This time fwknopd reports that the SPA packet is encrypted with GnuPG, and that a valid signature for the required key ID 5678DEFG is found:

    Feb 10 14:38:26 spa_server fwknopd: received valid GnuPG encrypted packet (signed with required key ID: "5678DEFG") from: 15.1.1.1, remote user: mbr Feb 10 14:38:26 spa_server fwknopd: adding FWKNOP_INPUT ACCEPT rule for 15.1.1.1 -> tcp/22 (30 seconds)

    Thwarting a Replay Attack

    Suppose that the SPA packet from the first example above was sniffed off the wire en route by a crafty individual on the system labeled attacker in the network diagram in Figure 1. The SPA packet always can be placed back on the wire in an effort to gain the same access as the original packet—this is known as a replay attack. There are several ways to acquire the packet data and replay it. One of the most common is to use tcpdump to write a pcap file (in this case tcpdump -i eth0 -l -nn -s 0 -w SPA.pcap port 62201 would work) and then use tcpreplay (see tcpreplay.synfin.net/trac) to copy the SPA packet back onto the wire. Another method, after the packet has been captured, is to use the echo command along with netcat:

    [attacker]$ echo "U2FsdGVkX1+BvzxXj5Zv6gvfCFXwJ+iJGKP \ qe2whdYzyigkerSp2WtvON/xTd8t6V6saxbg1v4zsK+YNt53BE8EI \ nxVCgpD7y/gEBIg8sd+AvU1ekQh9vwJJduseVx \ DxjmAHx3oNnClo2wckBqd8zA" |nc -u 16.2.2.2 62201

    On the fwknopd server, the duplicate SPA packet is monitored, but because the MD5 sum matches that of the original SPA packet, no access is granted, and the following message is written to syslog on the spa_server system:

    Feb 10 14:14:24 spa_server fwknopd: attempted \ message replay from: 18.3.3.3

    Conclusion

    Single Packet Authorization provides an additional layer of security for services such as SSHD, and this layer strikes at the first step that an attacker must accomplish when trying to compromise a system: reconnaissance. By using iptables in a default-drop stance and fwknop to sniff the wire for specially constructed (that is, encrypted and non-replayed) packets, it is difficult even to tell that a service is listening, let alone communicate with it. The end result is that it is significantly harder to exploit any vulnerabilities a protected service might have.

    An excellent source of additional theoretical information about both port knocking and Single Packet Authorization can be found in Sebastien Jeanquier's Master's thesis at the Royal Holloway College, University of London. The thesis can be downloaded from web.mac.com/s.j, and it includes an excellent argument for why SPA is not “security through obscurity”.

    Reading Stephen King's 'It': Still unsettling, all these years later | killexams.com real questions and Pass4sure dumps

    My eighth-grade English teacher had a no-Stephen-King rule — which was rich considering that she made us read Ayn Rand's "Anthem" — but King's new novel about an evil clown menacing the small town of Derry, Maine, was the size of a Buick, so she allowed me to do my book report on "It."

    I've written in these pages before about discovering a disintegrating copy of "The Shining" in a rural Colorado restaurant-bar when I was 8 or 9. For years afterward, I read every book by Stephen King I could get my hands on. "The Stand," "Cujo," "Christine," "'Salem's Lot," "Pet Sematary," "Night Shift," "Different Seasons," "Carrie," "The Dead Zone," the Richard Bachman novels, even "The Eyes of the Dragon," which my dad had to hunt down in hardcover as soon as it came out.

    King's stories never terrified me in a classic keep-the-lights-on, check-the-closets sense. (No fiction ever did when I was a kid, except for Jay Anson's silly "Amityville Horror" — that red-eyed pig looking down from the window is seared into my mind.) They unsettled me more profoundly than that.

    Take "The Jaunt," a short story from "Skeleton Crew," for instance. It's about teleportation via an interdimensional portal (or something). Travelers are sedated before being teleported, because people who made the journey while conscious were either driven insane or died instantly. A man whose family is about to teleport to Mars explains to his children that the process, although physically instantaneous, seems to a conscious mind to last forever. One of the guy's curious kids manages to circumvent the sedation, and he comes out the other side a second later shrieking, "It's longer than you think, Dad!" before clawing out his own eyes.

    How long? I mean, imagine being suspended in whiteness with only your thoughts for a year, much less 10 or 20 years. Then imagine a hundred, a thousand, a billion years. You can't imagine it, but I couldn't stop trying.

    Yeah, Stephen King freaked me out a lot. So I was psyched for "It." The plot is straightforward: The demonic clown Pennywise, aka It, murders children in Derry every 27 years; six boys and a girl, Beverly, form the Losers' Club and battle Pennywise. I don't remember what I wrote in my book report, but I remember being flummoxed by the ending. I don't think anyone has ever read the novel without being flummoxed by the ending, in which — spoilers for the novel and the new film follow — the turtle who created the universe tells Bill, the Losers' leader, how to stop Pennywise, which he does. Yes, I said the turtle who created the universe, but that's not the flummoxing part. After getting rid of It, the kids are lost in the sewers beneath Derry, and the only way for them to escape is to — well, as Wikipedia puts it, "Beverly has sex with all the boys to bring unity back to the group." That's right: The six 11-year-old boys take turns having sex with the 11-year-old Beverly. (I remember saying "What?" out loud several times when I first read this scene, as did my girlfriend when she read it the other day.)

    HANDOUT

    “It” by Stephen King.

    “It” by Stephen King. (HANDOUT)

    How would you film this? You wouldn't. The new film version of "It" nixes the novel's ending — as did the 1990 miniseries — but the filmmakers have replaced it with a conclusion that is almost as humanly and politically regressive. In the novel and the movie up to their respective conclusions, Beverly is a fierce, independent girl, about as damsel-in-distressed as Ripley in "Alien." In the novel, she becomes a passive vessel to receive the boys' burgeoning masculinity; in the new film, she ends up as just another of Pennywise's victims, hanging in midair in the clown's lair like a pinata until the boys rescue her, reviving her with a kiss like Sleeping Beauty. Sigh.

    There are a lot of bad Stephen King movies ("Maximum Overdrive," "Silver Bullet"), some good ones ("Stand by Me," "The Mist"), one very good one (David Cronenberg's "The Dead Zone," with Christopher Walken doing an excellent Christopher Walken impression), and two great ones (Brian De Palma's "Carrie" and Stanley Kubrick's "The Shining"). "It" is OK. The CGI is better than the animatronic spider from the miniseries, but the parts that are meant to be scary sometimes look like a community-theater production of "The Walking Dead." Pennywise is genuinely creepy, though. Bill Skarsgard plays the clown like a manic-depressive imp, swinging from gleeful to sinister in the time it takes a balloon to pop. And Sophia Lillis is terrific as Beverly.

    Sometimes I look up old Superman comics online. The issues I had in the late 1970s and early '80s serve as proverbial madeleines, transporting me back to afternoons in my room at my grandmother's house in Kansas. And don't get me started on "Goodnight Moon," which basically acts as a hallucinogenic on my memories.

    Rereading "It" today is to reread my eighth-grade self, retreating into books to avoid bullies. I read "Crime and Punishment" that same year, in the Constance Garnett translation, not for a class but because I spent so much time in the school library browsing the shelves. I was much taken by the sentence "He had successfully avoided meeting his landlady on the staircase" — an elegant telescope of psychological insight.

    I'd forgotten how weird "It" is. The movie doesn't even try to capture the surreal metaphysical stuff like Turtle the Creator or how the Losers see a vision of It smashing to Earth like an asteroid millions of years ago. And King's prose is often better than I'd assumed I'd find it: The opening sentence is tersely rhythmic: "The terror, which would not end for another twenty-eight years — if it ever did end — began, so far as I know or can tell, with a boat made from a sheet of newspaper floating down a gutter swollen with rain."

    Bill Skarsgård plays a monster that takes the shape of a clown called Pennywise in the movie remake of "It," based on the Stephen King novel.

    And though the movie, despite being set in a small mill town in the '80s, has no political consciousness to speak of, King's story, for all its problematic facets, is alive to its times (it alternates between the '50s and '80s). The father of one of the Losers is given to reminiscence: "In Lewiston they were worried about tramps and hobos and that something called 'the bonus army' would join up with something they called 'the Communist riff-raff army,' by which they meant any man who was out of work. The Legion of Decency used to send these fellows out of town just as fast as they came in." This must have been my first encounter with Marx's concept of "surplus population."

    Freud's concept of "das Es," "the It" — borrowed from Georg Groddeck and improperly translated as "the Id" by James Strachey — refers to the "unknown and uncontrollable forces" that govern our psychic lives. It would be easy to assimilate "It" to a reading along these lines, especially as all too knowable forces are loose in Derry — racism, domestic abuse, poverty, unemployment, McCarthyism and Reaganism. Perhaps the monster the Losers call It is a proxy for these or for the unconscious; the standard accounts of why we turn to the uncanny suggest that I escaped into horror novels, with their imaginary hence harmless terrors, to escape the misery of my adolescent schooldays.

    These explanations make a tidy intuitive sense, which is why I distrust them. People like to come up with theories for why we enjoy watching hockey-masked crazies carve up campers. "Can't you guys just let a story be a story?" asks the adult Bill, who has become a novelist. But that's no good either. I don't know why I like to read Peter Straub or watch "Halloween." But rereading "It" reminded me we should let eighth-graders do both.

    Michael Robbins is the author, most recently, of "Equipment for Living: On Poetry and Pop Music."

    New Employee Frequently Asked Questions | killexams.com real questions and Pass4sure dumps

    When can I enroll for benefits? Full-time and part-time employees are eligible to enroll in the benefits plan on the first of the month following your date of hire. For more information, visit our benefits page. How do I get onto payroll?

    You must complete a New Employee Packet, which includes: biographical information, tax forms, Form I-9 (Employee Eligibility Verification Form) and direct deposit information.

    The submission process for this packet differs, depending on the type of employee you are becoming (e.g., full-time/part-time, faculty, student, temporary workers, etc.). Please see below to make sure you are following the correct guidelines for the type of position for which you are being hired:

  • Regular full-time and part-time employees who applied through Drexel Jobs received an official offer letter. If this applies to you, you are required to complete preliminary forms at the time of acceptance. Please bring your completed New Employee Packet with identification to your new employee orientation. If you need to reprint these forms, they are available in PDF format on our New Employee Forms page.
  • All other new employees (including faculty, adjuncts, student employees, work study students, co-ops and temporary workers) are not sent these forms, but still need to fill out the appropriate paperwork. Print out the packet that applies to you from the New Employee Forms page, complete it, and then bring it to Human Resources (3201 Arch Street, Suite 430) along with two forms of identification that are listed in the packet.
  • Where do I pick up my first check?

    Paychecks for employees who do not sign up for direct deposit will be mailed to the home address on file. You can check your home address on DrexelOne by selecting the Drexel tab and then "View Home Address(es) and Phone(s)." If you need to update your home address, please email hris@drexel.edu from your Drexel Official Email address and include your University ID, updated address, and effective date of your address change.

    It could take up to two pay periods for employees who sign up for direct deposit to receive their paycheck through direct deposit. After signing up for direct deposit, employees should always verify the available balance in their bank accounts before making any payments. Once your direct deposit is active, you will no longer receive a paper pay check stub. You will instead receive an email notification that a direct deposit has been processed for you, which will direct you to view and print your paystub information using DrexelOne. Please see the Payroll instructions for more information on accessing your pay stub information. For additional instructions please visit the Office of the Comptroller website.
