Discussion

Malicious code protection mechanisms include, but are not limited, to anti-virus and malware detection software. In order to minimize potential negative impact to the organization that can be caused by malicious code, it is imperative that malicious code is identified and eradicated. Applications providing this capability must be able to perform actions in response to detected malware. Responses include blocking, quarantining, deleting, and alerting. Other technology- or organization-specific responses may also be employed to satisfy this requirement. Malicious code includes viruses, worms, Trojan horses, and Spyware. This requirement applies to applications providing malicious code protection.
