tcpdump and ngrep
tcpdump -nnvvAi eth1 -s0 | grep "Doug Burks is teaching SANS SEC503 Intrusion Detection In-Depth in Portland"So what does it all mean?
-nn This option disables name resolution for IP addresses and port numbers. Some versions of tcpdump do this with a single "-n", but the double "-nn" option should work on all of them.
vv This option enables Very Verbose output. It wasn't strictly needed for the purposes of this command, but I'm in a habit of using it.
A This option prints just the ASCII text in the packets. This is useful when looking for strings like "Doug Burks is teaching SANS SEC503 Intrusion Detection In-Depth in Portland" or "c99shell".
i This option allows you to specify the Interface (in this case eth1). eth1 on my Security Onion box at home is connected to a Dualcomm Switch Tap that monitors all ingress/egress of my home network. Doesn't everybody do full packet capture at home?
-s0 This option sets the snaplen. By default, tcpdump only captures 68 bytes and would therefore not see the entire payload of the HTTP connection. Setting snaplen to 0 forces tcpdump to capture the entire packet regardless of its size.
grep Since we had tcpdump output in ASCII, we can easily use the standard grep command to look for interesting text strings.
I was waiting on someone to ask the question "Why not use ngrep instead?". tcpdump's advantage is that it is more universally available than ngrep. If you're doing Incident Response on a Unix box of some kind, chances are that it already has tcpdump installed and you can use that to look for suspicious traffic as defined above.
Most Unix boxes do not have ngrep installed by default. But let's assume that you've got a dedicated IDS platform such as
ngrep -d eth1 -s0 "Doug Burks is teaching SANS SEC503 Intrusion Detection In-Depth in Portland"Here we use the "-d eth1" option to force ngrep to listen on device eth1 and the "-s0" option to force ngrep to look at the entire packet. Note that, unlike tcpdump's default snaplen of 68 bytes, ngrep defaults to 65536, so this option isn't strictly needed here, but is included for completeness. After specifying these options, we simply tell ngrep what string to look for.

SANS 401 Security Essentials mentored by Doug Burks in Augusta GA
SANS 401 Security Essentials mentored by Doug Burks in Augusta GA
Why should you take SANS 401 Security Essentials?
* Considering the SANS Cyber Guardian program, SANS GSE (GIAC Security Expert) certification, or a Masters degree from the SANS Technical Institute? SANS 401 Security Essentials is required for each of these.
* Complement your CISSP. If you've already taken the CISSP, SANS 401 Security Essentials is the perfect technical complement. It takes all the theory that you learned at a high level for the CISSP and applies it in a very practical and updated manner. SANS 401 is "where the rubber meets the road".
* Are you a Systems Administrator or Network Engineer who would like to learn more about security? This course gives a very thorough overview of security theory and practice. Additionally, the tools and techniques that you learn in this class are directly applicable to your current job (and will prepare you for the future).
* Augment your Windows/Linux skills. Highly experienced with Windows, but not so much with Linux? Or the other way around? SANS 401 Security Essentials dedicates an entire section to Windows security and another entire section to Linux security.
These are just a few reasons to register for SANS 401 Security Essentials. For more information, please see:

Don't forget that ISSA members are eligible for a 25% discount! If you would like to register for the ISSA and/or SANS 401, please let me know and I'll be glad to help!

Know Thy ISP
"Investigators may not yet know who was behind a series of cyberattacks on the U.S. and South Korea, but analysts are getting a better grasp on where the nations' governments may have gone wrong. Numerous government Web sites in both countries have been hit by distributed denial-of-service attacks, starting on the Fourth of July and continuing into today. Dozens of high-profile sites have been targeted, including those of the Federal Trade Commission, the Department of Treasury, and other major federal agencies."Quote of the day:
"'Too many federal agency security people did not know which network service provider connected their Web sites to the Internet,' explains Alan Paller, director of research at the SANS Institute, a security research organization."Alan's statement is quite scary, but I'm sure quite true. When the killer clowns come knocking at your firewall's door, you need to be able to pull the plug in a hurry. Perhaps we should have Internet fire drills where we propose a mock DDoS attack and have our technicians play out the scenario. Who ya gonna call?

What can it be used for?
- The Security Onion LiveCD can be used for Intrusion Detection. Simply boot the CD and double-click either the Snort-Sguil or SnortSP-Sguil desktop shortcuts. The Snort and Sguil daemons will then start, listening on eth0 for any suspicious traffic and creating alerts in the Sguil console.
- The Security Onion LiveCD can be used to test an Intrusion Detection System. Simply boot the CD and use the included tools (such as nmap, metasploit, idswakeup, scapy, hping, and others) to test your existing IDS or to test the included Snort 2.8.4.1 and Snort 3.0 Beta 3.
- The Security Onion LiveCD can be used to install an Intrusion Detection System. Simply boot the CD and double-click the Install desktop shortcut. For more information about installation, please see the README desktop shortcut.
Please take a look at the Security Onion LiveCD and let me know what you think!
