Description
The malicious software detection functionality on network elements needs to be constantly updated in order to identify new threats as they are discovered. All malicious software detection functions must come with an update mechanism that automatically updates the application and any associated signature definitions. The organization (including any contractor to the organization) is required to promptly install security-relevant malicious code protection updates. Examples of relevant updates include anti-virus signatures, detection heuristic rule sets, and/or file reputation data employed to identify and/or block malicious software from executing. Malicious code includes viruses, worms, Trojan horses, and Spyware. This requirement is limited to ALGs, web content filters, and packet inspection firewalls that perform malicious code detection as part of their functionality.

If the BIG-IP ASM module is not used to support content filtering as part of the traffic management functions of the BIG-IP Core, this is not applicable. When content filtering is performed as part of the traffic management functionality, verify the BIG-IP ASM module is configured to update malicious code protection mechanisms and signature definitions whenever new releases are available in accordance with organizational configuration management policies and procedures. Verify the BIG-IP ASM module is configured to update malicious code protection mechanisms when providing content filtering to virtual servers for whenever new releases are available in accordance with organizational configuration management policies and procedures. Navigate to the BIG-IP System manager >> Security >> Options >> Application Security >> Attack Signatures >> Attack Signature Updates. Review the following settings to confirm compliance with organizational configuration management policies and procedures: Update Mode is set to "Manual", unless defined differently by the Organization. Delivery Mode is set to "Automatic", unless defined differently by the Organization. Verify that "Auto Apply New Signatures Configurations After Update" is NOT "Enabled", unless defined differently by the Organization. If the BIG-IP ASM module does not update malicious code protection mechanisms whenever new releases are available in accordance with organizational configuration management policies and procedures, this is a finding.
