Description
The organization must employ malicious code protection mechanisms at information system entry and exit points. This protection must detect and eradicate malicious code transported by electronic mail, electronic mail attachments, web accesses, removable media, or inserted through the exploitation of information system vulnerabilities. Malicious code provides the ability for a malicious user to read from and write to files and folders on a computer's hard drive. They also have the ability to run and attach programs, which provides a high risk potential for the distribution of malicious mobile code. Malicious code can be transported by electronic mail, mail attachments, web accesses, and removable media. Malicious code includes viruses, worms, Trojan horses, and spyware. While the IDPS cannot replace anti-virus or HIDS protection installed on the network's endpoints, sensor rules can be implemented which provide preemptive defense against both known and zero day vulnerabilities. Many of the protections may provide defenses before vulnerabilities are discovered and rules or blacklist updates are distributed by anti-virus or malicious code solution vendors.

Check Text ( C-43047r1_chk )
Review the rules of the IDPS. Verify malicious code protection mechanisms are implemented to detect and eradicate malicious code at the network perimeter (e.g., blacklists, whitelists, malware protection, and behavior analysis). If the IDPS does not employ malicious code protection mechanisms to detect and eradicate malicious code at the network perimeter, this is a finding.

Fix Text (F-39079r1_fix)
