To detect and prevent viruses and worms on a Cisco ASA, the best method would be content security via the Control Security Services Module (CSSM).
Content security via the CSSM allows for a range of security measures to be deployed on the ASA, including antivirus, antispyware, antiphishing, and antispam protection. The CSSM leverages a range of technologies to detect and prevent malware, including signature-based detection, behavior-based analysis, and reputation-based filtering.
Deep packet inspection (Option A) is a method of analyzing the contents of network traffic in real-time to identify and block malicious traffic. While deep packet inspection can be effective in detecting and blocking some types of malware, it is not as comprehensive as content security via the CSSM.
Unicast Reverse Path Forwarding (Option C) is a security feature that is used to prevent IP spoofing attacks. While it can help to prevent certain types of network-based attacks, it is not specifically designed to detect and prevent viruses and worms.
IP audit signatures (Option D) are a feature of the ASA that allow for the creation of custom signatures to detect and prevent specific types of attacks. While this can be effective in detecting and preventing targeted attacks, it is not as comprehensive as content security via the CSSM.
In summary, content security via the Control Security Services Module is the best method to deploy on a Cisco ASA to detect and prevent viruses and worms due to its comprehensive range of security measures and advanced malware detection capabilities.
