This chapter explored the many faces of traffic using ports 53 UDP and TCP Since almost every Internet site relies on DNS, it's important to understand the protocol's normal, suspicious, and malicious aspects We started the chapter with a look at normal traffic passed on port 53 UDP and TCP The normal traffic was run-of-the-mill UDP-based DNS, albeit with larger payloads than we expected Using the dnsquery command, we forced DNS over port 53 TCP Zone transfers were shown as a form of TCP-based DNS that is normal if done between master and slave DNS servers but malicious if done by an unauthorized party We explored how global LBSs use odd TCP segments to measure latency by prompting responses from DNS servers The suspicious UDP traffic was caused by a creative way to distribute BitTorrent files over DNS The malicious traffic was the result of an intruder running Tunnelshell The covert channel was easy to spot because it looked nothing like normal DNS traffic on port 53 UDP We concluded with a look at a query for the version of BIND running on a target, and an examination of an unsuccessful attempt to exploit BIND This chapter relied heavily on alert and full content data to detect and validate events In the next chapter, we turn to session data to understand an intrusion scenario

15 Harnessing the Power of Session Data
Create UCC - 12 In Visual Studio .NET
Using Barcode encoder for Visual Studio .NET Control to generate, create UPC-A Supplement 5 image in VS .NET applications.
Of all the sources of NSM information, session data is the most useful Session data quickly reduces millions of packets to summaries of conversations or flows These conversations show who talked to whom, when, using what ports and protocols, for how long, and how much data was passed during the session The content of the session is not captured unless full content monitoring is performed on one or more packets of the session Session data is the incident responder's best friend because it answers three out of the four most pressing questions a decision maker faces Can you guess which one session data cannot answer 1 2 3 4 Are one or more servers definitely compromised If one or more servers are compromised, what did we lose Where else did the intruder go Is the intruder back today
Make Bar Code In .NET Framework
Using Barcode creation for VS .NET Control to generate, create barcode image in .NET framework applications.
If you realized that session data, due to its content-neutral methodology, couldn't help answer question 2, you're getting the hang of NSM Session data could potentially reveal how much data was passed during a conversation by monitoring packet and byte counts, but only full content collection of unencrypted traffic definitively reveals what an intruder accessed Session data can help answer the other three questions It's not an exact science, but by playing the odds and making logical assumptions, you can make plenty of investigative progress

The Session Scenario
Decoding EAN / UCC - 13 In Visual Studio .NET
Using Barcode recognizer for VS .NET Control to read, scan read, scan image in VS .NET applications.
Let's put session data to work in the following scenario Imagine we are working on the security team of a small company We realize that an unauthorized system has successfully connected to our wireless access point All we know at the outset is the IP address of the wireless system Figure 151 shows the network diagram

Thankfully, we run Argus to collect session data on all interfaces of the FreeBSD-based firewall/gateway We actually operate seven separate instances of Argus The first watches traffic seen on the firewall interface connected to the wireless segment The second watches the interface connected to the DMZ segment The third, fourth, fifth, and sixth instances of Argus each watch one of the VLANs, numbered VLAN0 through VLAN3 The seventh watches traffic to and from the Internet
Creating Code39 In Visual C#
Using Barcode generator for VS .NET Control to generate, create ANSI/AIM Code 39 image in VS .NET applications.
By examining each set of Argus data, we can hopefully track any intruder's movement Using session data is an example of performing traffic analysis While the content of the conversations is not visible, the fact that a communication took place should be Keep in mind that deployment choices (ie, sniffing on the firewall) may affect the traffic available for examination
