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.
I had the pleasure of attending the inaugural signing of National Cybersecurity Excellence Partnership agreements yesterday. Key stakeholders in attendance included National Security Agency Director, General Keith Alexander, Senator Barbara Mikulski, Dr. Pat Gallagher of the National Institute of Standards and Technology (NIST), Maryland Governor Martin O’Malley, and several members of the Cisco team.
Established in 2012 through a partnership between NIST, the State of Maryland, and Montgomery County, the National Cybersecurity Center of Excellence (NCCoE) was conceived to advance innovation through the rapid identification, integration, and adoption of practical cybersecurity solutions. NCCoE collaborates with industry leaders through its National Cybersecurity Excellence Partnership (NCEP) initiative to develop real-world cybersecurity capabilities.
As a NCEP member and key collaborator, Cisco is dedicated to furthering the mission of securing cyberspace for all. As part of this ongoing commitment, Cisco has launched the Threat Response, Intelligence and Development organization, focusing key resources around cyber security, threat mitigation and network defense for our customers. Read a blog from our CSO John Stewart about this new organization and its charter here. Read More »
A couple of weeks ago, I announced a new name and a new mission for the group I lead at Cisco. I’ll do my best to minimize reader exposure to boring administrative details, but the long and the short of it is that the former Cisco Global Government Solutions Group (GGSG) has become the Cisco Threat Response, Intelligence, and Development (TRIAD) organization.
Any organizational name change is only a label placed on more fundamental transformations in missions, strategies, and desired outcomes. While the new organization will continue to serve government customers, the time has come to mobilize the expertise we have built up over the years to help critical infrastructure and enterprise customers strengthen their abilities to deliver IT-based services and value with minimal disturbance from unauthorized sources.
Vectoring the organization’s mission to threat is the key to understanding what TRIAD is all about. Through our work with Cisco customers, observation and analysis of phenomena visible in Cisco and customer networks, and application of innovative thinking about security practices and processes, we see enormous potential for developing and delivering threat-focused approaches to cyber security into products, services, and solutions.

If you’re an end-user or manager of software that has publicly known security vulnerabilities, wouldn’t you want to know about it? If you’re a software developer, wouldn’t you want to know if there are third-party software vulnerabilities that may impact your applications or products? Do you have a patch management compliance requirement for managing software vulnerabilities? I presume the answer is a resounding “Yes” to each question that applies to you. Anything we, as cyber security professionals, can do to help automate the vulnerability management process, while integrating security intelligence into that process from both an end-user and developer perspective, is a good thing. In this post, I will discuss Cisco’s Application Programming Interface (API) that exposes security intelligence as a direct data feed into applications or portals. The API is known as the IntelliShield Security Information Service (ISIS) and has proven effective to answering these leading questions.
“Continuous improvement in vulnerability management practices is imperative to keeping pace with the changing security environment as a result of evolving threats as well as new products and technologies” Russell Smoak, Cisco Systems, Cisco 2013 Annual Security Report
The above quote underscores the importance of striving to raise the bar in protecting against vulnerabilities, which may be exploited in your environment, or in the case of a developer, the products you provide to your customers. Cisco uses ISIS several ways, both internally and externally. Internally, Cisco takes advantage of custom-built tooling that uses vulnerability data from Cisco IntelliShield to notify the product development teams when a security issue originating in third-party software may impact a Cisco product. This tool has greatly increased the ability to manage security issues that originate in non-Cisco code. Externally, ISIS is used to provide the content to several sections accessible through the Cisco SIO portal. A couple of examples include:
- IOS Software Checker: this tool is used to query Cisco IOS Software Releases against published Cisco Security Advisories.
- Security Alerts: this tool provides an “At-A-Glance” type of view of security events such as vulnerability exposures.
Technically, ISIS provides a set of services that support application-to-application interaction using SOAP over the HTTPS protocol, allowing clients to develop ISIS-dependent applications that are not dependent on the technologies used to implement ISIS. The only dependency is for the client to have the ability to produce a SOAP message, send it to ISIS over HTTPS, and ultimately decompose the SOAP response. These services also allow clients to filter the security intelligence based on various inputs, enabling clients to align IntelliShield security intelligence with the unique business needs of their environment.

Cross-Site Request Forgery (CSRF) attacks: there are already enough articles out there that can explain what a CSRF attack is and provide potential examples. There are also plenty of security alerts that have been released by various vendors whose products are affected by CSRF-related vulnerabilities.
CSRF attacks usually target web applications and attempt to make unwanted changes on server data or extract sensitive information from a web application. Attackers do this by luring an authenticated user into making a specially crafted web request. It’s important, regardless of role, for everyone to have a basic understanding of CSRF attacks and the available options to protect against them.
For more information about basic CSRF concepts and potential mitigations, see our new Applied Mitigation Bulletin Understanding Cross-Site Request Forgery Threat Vectors. Although this document does not attempt to provide all the technical details associated with CSRF, it does aim to summarize the CSRF technique and provide methods that can be potentially used by developers, network administrators and users to protect against CSRF attacks.
