In October, we announced details about Cisco PSIRT’s new and improved security vulnerability disclosure format. Our Chief Security and Trust Officer, John Stewart, also revealed that Cisco will launch an application programming interface (API) that empowers customers to customize Cisco vulnerability information and publications. Today, we have officially launched the Cisco PSIRT openVuln API and it is available for immediate use.
The Cisco PSIRT openVuln API is a RESTful API that allows customers to obtain Cisco security vulnerability information in different machine-consumable formats. It supports industrywide security standards such as the Common Vulnerability Reporting Framework (CVRF), Open Vulnerability and Assessment Language (OVAL), Common Vulnerability and Exposure (CVE) identifiers, and the Common Vulnerability Scoring System (CVSS).
This API allows technical staff and programmers to build tools that help them do their job more effectively. In this case, it enables them to easily keep up with security vulnerability information specific to their network. That frees up more time for them to manage their network and deploy new capabilities in their infrastructure.

Cisco is committed to protecting customers by sharing critical security-related information in different formats. Guided by customer feedback, Cisco’s Product Security Incident Response Team (PSIRT) is seeking ways to improve how we communicate information about Cisco product vulnerabilities to our Customers and Partners. As John Stewart mentioned on his blog post, the Cisco PSIRT has launched a new and improved security vulnerability disclosure format. The new Cisco Security Advisories can be accessed at http://www.cisco.com/go/psirt and at http://cisco.com/security
The intent is to make it easier for Customers and Partners to access information about all security vulnerabilities in Cisco products. Each vulnerability disclosed through our new security advisories are assigned a Common Vulnerability and Exposures (CVE) identifier to aid in identification. Additionally, Cisco will continue to assess all vulnerabilities using the Common Vulnerability Scoring System (CVSS). Check out the sites for CVE, CVSS, and this CVSS scoring calculator if these terms are relatively new to you or you simply need a refresher.

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.

UPDATE: Webcast information is also now available at the Cisco Live 365 site
Many network security administrators are struggling to keep their network “up-to-date” with the constant release of new vulnerabilities and software fixes. At the same time, they’re under pressure to provide near 100% availability of key business services and systems. Every time a vendor discloses a security vulnerability, network security administrators must identify affected devices and (in numerous cases) upgrade such devices. These activities can take hours, days, or even weeks depending on the size of the organization. For instance large enterprises and organizations may have thousands of routers and switches that need to be assessed for the impact of any given vulnerability. Cisco is helping customers by adopting cutting-edge security automation standards such as the Open Vulnerability and Assessment Language (OVAL) and the Common Vulnerability Reporting Framework (CVRF).
In the following blog posts, I’ve provided details about how security automation is helping customers:
Additionally, my colleague Mike Schiffman has posted several posts explaining CVRF.
Webcast took place on Tuesday, April 23rd at 10:00 a.m. EST (14:00 GMT). Over 150 customers from 29 countries learned about security automation; Cisco’s machine readable content strategy; and vulnerability assessment using OVAL. We discussed how customers can use OVAL to quickly assess the effects of security vulnerabilities in Cisco IOS Software devices. The recording is now available:

In this article, you will be provided a thorough treatise on an in-house developed tool for parsing and validating CVRF documents aptly named “cvrfparse”. The article is split into two parts. The first part, intended for CVRF document producers and consumers, is a hands-on manual detailing how to use cvrfparse. The second part, intended for burgeoning Python programmers, explores some of the inner workings of the tool.
The CVRF parser or “cvrfparse” is a Python-based command line tool that offers simple parsing and validation of CVRF documents. Using it, you can quickly query a CVRF document for any of its contents. For example, let’s say one of your vendors releases a bundle of security advisories encoded in CVRF. There are a dozen individual CVRF documents each with multiple vulnerabilities across hundreds of products. Using cvrfparse, you can quickly ascertain which documents contain vulnerable products you might have installed in your infrastructure. We’ll see how, shortly.
