Abstract
Methods, systems, and computer-readable media are disclosed for packet sanitization. A particular method intercepts a packet of a packet stream, where the packet stream is transmitted in accordance with a particular protocol. The packet is analyzed based on a specification associated with the particular protocol. Based on the analysis, a data value of a field of the packet is replaced with a sanitized data value to create a sanitized packet. The sanitized packet may be injected into the packet stream or may optionally be forwarded to a signature module that checks the sanitized packet for malicious content. When malicious content is found, the sanitized packet may be dropped, the sanitized packet may be logged, the sanitized packet may be redirected, or a notification regarding the sanitized packet may be sent to an administrator.
