Today the web is a favorite vector for threat actors to launch their attacks. According to the Cisco 2014 Midyear Security Report, More than 90 percent of customer networks observed in the first half of 2014 were identified as having traffic going to websites that host malware. More recently, Talos uncovered a massive malvertising network known as Kyle and Stan. Some 31,151 connections were observed to the network’s 6,491 domains.
In an effort to continue offering the most comprehensive protection to our customers, today we are announcing several important new features and expanded threat protection for the Cisco Web Security Appliance (WSA).

As part of CSIRT’s mobile monitoring offering for special events, we undertook monitoring of the corporate and customer traffic of the Cisco House at the London 2012 Olympics. This engagement presents us with an excellent opportunity to showcase Cisco technology, while keeping a close watch on potential network security threats. CSIRT monitoring for this event will be active for the entire life-span of the Cisco House, from two months before the Olympics, until two months after.
For the London 2012 engagement, we shipped our gear in a 14RU military-grade rack that is containerized: made for shipping. Inside the mobile monitoring rack we have an assortment of Cisco kit and third-party kit that mirrors the monitoring we do internally:
- Catalyst 3750 to fan out traffic to all the other devices
- FireEye for advanced malware detection
- Two Cisco IronPort WSA devices for web traffic filtering based on reputation
- Cisco UCS box where we run multiple VMs
- Lancope StealthWatch collector for NetFlow data
- and a Cisco 4255 IDS for intrusion detection
We mirror the signatures that we have deployed internally at Cisco out to these remote locations. Depending on the environment where the mobile monitoring rack is deployed, we may also do some custom tuning. The kit in the mobile monitoring rack can do intrusion detection, advanced malware detection, and collect and parse NetFlow and log data for investigation purposes. The Cisco UCS rack server also helps us have several VMs, allowing us to run multiple tools that complement the other devices in the rack. For example, we run a Splunk instance on a VM to collect the logs generated by all the services. The data from the gear in the mobile monitoring rack is analyzed by our team of analysts and investigators, to eliminate false positives, conduct mitigation and remediation, and finally produce an incident report if required.
