Cross-Site Request Forgery Attacks and Mitigations

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.

Why the Cisco SIO Portal Doesn’t Give Out Candy

“Change is inevitable—except from a vending machine.”

In the spirit of Robert C. Gallagher’s famous quote—and in our quest to never be a vending machine—we’ve rolled out several updates to Cisco’s Security Intelligence Operations (SIO) Portal which I trust you will find useful. Thanks to your feedback, we continue to evolve the Portal to ensure that relevant security content is where you need it, when you need it. Providing timely information to our customers requires not only a global team of Cisco security experts to pipeline the latest information, but a complementary team who ensures that the most significant issues are also the most visible. In fact, that’s the most exciting change we made: a new ‘Security Highlights’ tab which allows a cross-functional group, led by our content managers, to call out the most important issues to our customers. That way, instead of looking at IntelliShield alerts, Cisco Security Notices, or Event Responses individually when time is scarce, this new tab gives you an at-a-glance view of Cisco security content our experts feel is most pressing given all of the events into which we have a view.
