Reflections from a road trip: The evolving risk of DDoS attacks

Recently, I spent time with some of our customers discussing recent security events and the threat landscape. As a leader for vulnerability handling, we often have to deliver news regarding our products that can cause significant disruption for patching and remediation. I always appreciate the time that customers take to provide feedback on our products and services.

The dominant topic during conversations with customers was the threat landscape, specifically the Distributed Denial of Service (DDoS) attacks that have and are currently taking place. While DDoS attacks are certainly not new territory for our industry, there were some interesting observations we discussed regarding the nature and impact of such activities. Read More »

We Are Listening. Keep the Feedback Coming!

During the 2012 fall season, we launched a survey that seeks to understand how you use and value the security resources on the Cisco Security Intelligence Operations Portal at http://cisco.com/security. At the same time we also made available our enhanced feedback mechanism—shown below highlighted in red—to allow you to more easily share your thoughts and frustrations with our content.

The response has been fantastic; thank you.

Through the new survey and feedback systems, we are broadening our understanding of the content-types you find useful, those you don’t, as well as content you’re not familiar with. We have received very specific questions and feedback and done our best to respond directly when we could (did you include an email address?) and have responded publicly via @CiscoSecurity a few times when no contact information was shared. For example, when an anonymous feedback-submitter suggested we provide RSS feeds for Cisco Security Advisories, we responded via Twitter with:

@CiscoSecurity: A friendly reminder, RSS feeds for all Cisco SIO content types, including Security Advisories, are available at http://cs.co/9007VQr7

Cisco Live London 2013: IPv6 Security Lab Recap

Last week my colleagues and I were excited to deliver a 4-hour lab on IPv6 Security at Cisco Live London 2013. The training enabled students to correctly identify, classify, and deter or prevent the nefarious IPv6-specific behaviors. They did so by configuring network threat defense, countermeasures, and controls that were implemented and deployed on infrastructure devices as well as validate their effectiveness. Some of the nefarious behaviors included IPv6 spoofing, using IPv6 in IPv4 tunneling to bypass, and DDoS using IPv6 packets. This IPv6 security training was first delivered at Cisco Live USA 2012, where 19 students participated in the class. At Cisco Live London, we welcomed 21 Cisco Customers, giving them access to our lab-hosted equipment to practice and complete tasks covered during class. What follows are some key observations about our training in London as compared to our training in the U.S.: Read More »

New White Paper: Testing the Efficacy of Cisco IPS

A few months ago we published a technical white paper explaining how we measure the performance of Cisco IPS sensors. The idea was to give Cisco IPS customers insight into the work that goes into producing the performance numbers that are recorded in a data sheet, with the ultimate goal of helping customers deploy the correct IPS appliance for their environment. We have now followed up the performance work with a paper describing how we test the effectiveness of our IPS product line.

This new paper titled, “Testing the Efficacy of Cisco IPS”, explains how Cisco IPS fits into the Cisco Security portfolio and how the IPS product team measures efficacy.  Read More »
