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.
“A security advisory was just published! Should I hurry and upgrade all my Cisco devices now?”
This is a question that I am being asked by customers on a regular basis. In fact, I am also asked why there are so many security vulnerability advisories. To start with the second question: Cisco is committed to protecting customers by sharing critical security-related information in a very transparent way. Even if security vulnerabilities are found internally, the Cisco Product Security Incident Response Team (PSIRT) – which is my team – investigates, drives to resolution, and discloses such vulnerabilities. To quickly answer the first question, don’t panic, as you may not have to immediately upgrade your device. However, in this article I will discuss some of the guidelines and best practices for responding to Cisco security vulnerability reports.
It’s that time of year again, folks. On Wednesday of next week, the Cisco Product Security Incident Response Team (PSIRT) will release the first Cisco IOS Software Security Advisory Bundled Publication of 2013. As a reminder, Cisco 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 security advisories, vulnerabilities scheduled for disclosure in the upcoming bundle will normally have a Common Vulnerability Scoring System (CVSS) Base Score from 7.0 to 10.0.
