For those following Cisco security, you probably know Cisco acquired Sourcefire last year (more found HERE). The most anticipated release has been adding Sourcefire’s flagship Firepower offering inside Cisco’s most popular firewall offering the Adaptive Security Appliance (ASA). As of September 16th, this offering is officially available. You can find data sheets, configuration guides and more on the new release HERE. This post will cover steps I used to build my ASA with Soucefire lab. Continue reading
I built a CCIE lab a while back and found the process to be a bit cumbersome. The hardware and software requirements were clear (4.0 version found HERE), but not the actual construction of a home lab. Here is an explanation of how I built my lab. This is my experience so I’m not saying it’s the right way, but its how I did it. Continue reading
My buddy Aamir Lakhani wrote about a cool reconnaissance tool called recon-ng. This tool can automate researching a target using multiple sources. The original post can be found HERE.
Reconnaissance techniques are the one of the first steps penetration testers practice when learning how to exploit systems for vulnerabilities. Traditional reconnaissance techniques are used to gather intelligence, define scope, and identifying weaknesses. Continue reading
Jaeson Schultz and Craig Williams recently posed on the Cisco security blog about research on the latest snowshoe spam trends being seen. They explain the problem, what they are seeing and suggestions for remediation. The original post can be found HERE.
Every so often, we observe certain spam campaigns that catch our interest. On August 15, we observed a particular spam campaign that caught our attention because it was using “snowshoe” spam techniques combined with PDF exploitation. While neither of these techniques are new, we have seen a growing trend involving snowshoe spam and we wanted to explain why the bad guys seem to be moving in that direction with a real world example. As you can see from the chart below, we’ve seen the amount of snowshoe spam double since November of 2013.
Detecting threats on endpoints like laptops and mobile devices is important but not enough to defend against the threats we see against our users. Reason why is Anti-Virus and host IPS/IDS can only scan for so many signatures and leverage so many behavior checks before they must let the traffic go through or it will impact the user experience. This is why many users get compromised by clicking the wrong email, accessing the wrong website, share the wrong USB drive and so on. Detection needs to extend beyond the doorway and look at files that have breached a host’s defense to determine if that system has been compromised as well as offer a method to remediate the entire outbreak.

Many industries rely on revenue generated by sales and if credit is used, Payment Card Industry (PCI) compliance is mandated. This includes all industries that process, store or transmit credit card information. Like any compliancy standard, this is the minimal level of real security and should not be considered the goal to protect sensitive data. All compliance mandates that matter must go through various review and audit processes that take time and cause the results to be dated compared to the speed of new attacks you should expect against your network. This means meeting mandates such as PCI should just be part of your overall security strategy. Continue reading
The Cisco 2014 Midyear Security Report found HERE examines threat intelligence and security trends for the first half of 2014. Cisco’s research helps to underscore just how many different types of weak links exist in the systems we use. These weak links – which could be outdated software, bad code, abandoned digital properties, or user errors – contribute to the adversary’s ability to exploit vulnerabilities with methods such as DNS queries, exploit kits, amplification attacks, point-of-sale (POS) system compromise, malvertising, ransomware, infiltration of encryption protocols, social engineering and “life event” spam.

A buddy of mine at Cisco is truly a genius when it comes to thinking outside the box. He loves technology and hates annoying telemarketers. Over time, he developed a call management system that involves a combination of open source software and proprietary hardware. He took advantage of the numerous application programing interfaces (API’s) available to create a tightly integrated environment. Continue reading
