Many Cisco customers with an interest in product security are aware of our security advisories and other publications issued by our Product Security Incident Response Team (PSIRT). That awareness is probably more acute than usual following the recent Cisco IOS Software Security Advisory Bundled Publication on September 25. But many may not be aware of the reasoning behind why, when, and how Cisco airs its “dirty laundry.”
Our primary reason for disclosing vulnerabilities is to ensure customers are able to accurately assess, mitigate, and remediate the risk our vulnerabilities may pose to the security of their networks.
In order to deliver on that promise, Cisco has has made some fundamental and formative decisions that we’ve carried forward since our first security advisory in June 1995.

Today, we released the final Cisco IOS Software Security Advisory Bundled Publication of 2013. We committed to these predictable disclosures back in 2008 because your feedback was clear—they allow you to plan ahead and ensure resources are available to analyze, test, and remediate vulnerabilities in your environments. (For more information on the history of this evolution, take a look at my colleague John Stuppi’s post this past March.) If you haven’t had the opportunity to review my earlier posts on preparing for bundled disclosures or leveraging the Cisco IOS Software Checker tool, I’d encourage you to do so now. Hopefully, the guidance will help lessen the impact of evaluating the recently published Cisco Security Advisories. Read More »

It’s that time of year again—consider this post your friendly T-7 notice to start preparing for the final Cisco IOS Software Security Advisory Bundled Publication of 2013! As a reminder, the Cisco Product Security Incident Response Team (PSIRT) releases bundles of Cisco IOS Software Security Advisories on the fourth Wednesday of March and September each calendar year. As is the case with the vast majority of our advisories, vulnerabilities scheduled for disclosure in these upcoming Security Advisories will normally have a Common Vulnerability Scoring System (CVSS) Base Score from 7.0 to 10.0. Cisco security publications that disclose vulnerabilities scoring lower than 7.0 are described in our Cisco Security Vulnerability Policy. Read More »

The Common Vulnerability Reporting Framework (CVRF) is a security automation standard intended to make your life easier by offering a common language to exchange traditional security and vulnerability bulletins, reports, and advisories. You can read more about it on the official ICASI CVRF 1.1 page, in my CVRF 1.1 Missing Manual blog series, or in the cvrfparse instructional blog. CVRF 1.1 has been available to the public for almost a year and we would like to know how its helped and how we can improve it. Please take a moment to take the poll and please feel free to share it with any interested parties. Comments are encouraged and welcomed. The more feedback we get, the more we can improve CVRF.

Wow! We just published our tenth bundle of Cisco IOS Software Security Advisories and what a ride it’s been!! Way back when in the fall of 2008 when we produced our first Cisco IOS Software Security Advisory bundle, we had no idea of the impact that this delivery format would have on us internally and, more importantly, on you -- our customers!! The decision to deliver the biannual (on the fourth Wednesday of every March and September) Cisco IOS Software Security Advisory Bundled Publication brought with it many challenges, process changes, and—in the end—a format for Cisco Vulnerability Disclosure that we hope addresses at least some of your concerns. This format was modeled after the scheduled monthly release used by Microsoft for years, known affectionately as “Microsoft Tuesday” and based on requests we heard through discussions with many of our customers.
