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 These weak links – which could be outdated software, bad code, abandoned digital properties, or user errors – contribute to the adversary’s ability to exploit vulnerabilities with methods such as DNS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 →
One common question I’ve been asked is what are the current requirements to perform authentication, authorization, and remediation when using VPN (usually Cisco ASA VPN) and Cisco Identity Services Engine ISE. This post will cover this subject however I suggest for those with Cisco ASA 9.2.1 and ISE should reference this really good configuration guide found HERE. Continue reading →
Juniper Networks announced that it sold its Junos Pulse product to Siris Capital for approximately $250 million. Junos Pulse software enables dynamic SSL VPN connectivity, network access control (NAC), mobile security, and collaboration, through a simple end-user interface. It simplifies and optimizes connectivity to end users at the same time it check their device type and security state, location, identity, and adherence to corporate access control policies.

This week’s product overview is Cisco Security Manager also known as CSM. For some people, hearing CSM makes them cringe as older versions from 4+ years ago had some issues. Personally, I consider the recent CSM release a completely different solution and I’m sure just by the screenshots, people familiar with the old version will not recognize anything as its been completely rebuilt.
Cisco Security Manager is used to manage multiple Cisco security products. Management includes centralizing configuration, quickly troubleshooting security events, unifying software versions, backing up configuration, enforcing policies for best practice, and reporting. Products that can be managed by CSM include ASAs, IPS modules / Appliances, Firewall Service Modules, ISR routers, Switches and VPN. Its installed as a software package but can also be purchased as a bundle with a UCS server for those looking for a appliance feel. Continue reading →
