The CA API Gateway providing content filtering must be configured to perform real-time scans of files from external sources at network entry/exit points as they are downloaded and prior to being opened or executed.

Malicious code includes viruses, worms, trojan horses, and spyware. The code provides the ability for a malicious user to read from and write to files and folders on a computer's hard drive. Malicious code may also be able to run and attach programs, which may allow the unauthorized distribution of malicious mobile code. Once this code is installed on endpoints within the network, unauthorized users may be able to breach firewalls and gain access to sensitive data.

To guard against malicious code, real-time scans must be performed on files from external sources as they are downloaded and prior to being opened or executed.

The CA API Gateway must be configured to integrate with an ICAP-enabled Intrusion Detection System such as McAfee, Sophos, or Symantec. These systems must be configured in accordance with organizational requirements, which must include the real-time scanning of files from external sources.
