How Critical Security Controls Can Help Signaling System No. 7 (SS7)

by Hassan Mourad Oct. 4, 2017

For decades, the security of one of the fundamental protocols in telecommunications networks, Signaling System No. 7 (SS7), has been solely based on the mutual trust between the interconnecting operators. Operators relied on their trust in other operators to play by the rules, and the SS7 network has been regarded as a closed trusted network. This notion of trust and security has recently changed after several security researchers announced major vulnerabilities in the SS7 protocol that threa...

MIPS Malware Analysis

by Muhammad Junaid Bohio Oct. 3, 2017

Malware functionalities have been evolving and so are their target platforms and architectures. Non-PC appliances of different architectures have not traditionally been frequent targets of malware.

How to Find an Advanced Persistent Adversary

by Fayyaz Rajpari Oct. 4, 2017

The Advanced Persistent Threat is a commonly used term by security practitioners all over the world. Many believe these threats are in the form of hidden backdoors, stealthy credential stealers, and other crafty hacking tools. This is partially true, but it is a small component of the Advanced Persistent Threat. This generic term would be better described by the term, Advanced Persistent Adversary. It is the actor or groups behind these tools that are the real problem. Preventative secur...

Law Enforcement and the use of Artificial Intelligence (AI)

by John Wulff Oct. 4, 2017

After the 9/11 terrorist attacks against the United States, law enforcement, and intelligence communities began efforts to combine their talents and information gathering assets to create an efficient method for sharing data.

By leveraging tools easily available in every Linux distribution (and often in UNIX/Mac OS X) combined with Tcpdump to analyze network traffic, you can determine the make-­‐up of the network traffic in question find the most active hosts and protocols, search for oddities, and determine the most efficient next step of your investigation. Using this method, you are able t...

Using Static Analysis to Harden Open Source Intrusion Detection Systems (IDS)

by Jeff Sass Oct. 3, 2017

When deploying an open source Intrusion Detection System (IDS) into a network, it is critical to harden it against attackers. An IDS is designed to detect attacks instead of inadvertently enabling them. One approach to assist in this effort is to use static code analysis on the source code of the IDS. This paper details how to use Coverity’s static analysis tools on the Security Onion distribution to find security vulnerabilities. A look at Coverity’s security code checkers, with a focus towa...
