Abstract
A security module on a computing device applies security rules to examine content in a network cache and identify suspicious cache content. Cache content is identified as suspicious according to security rules, such as a rule determining whether the cache content is associated with modified-time set into the future, and a rule determining whether the cache content was created in a low-security environment. The security module may establish an out-of-band connection with the websites from which the cache content originated through a high security access network to receive responses from the websites, and use the responses to determine whether the cache content is suspicious cache content. Suspicious cache content is removed from the network cache to prevent the suspicious cache content from carrying out malicious activities.
