The BIG-IP ASM module must be configured to detect code injection attacks launched against application objects including, at a minimum, application URLs and application code, when providing content filtering to virtual servers.

Description
Data mining is the analysis of large quantities of data to discover patterns and is used in intelligence gathering. Failure to detect attacks launched against organizational applications may result in the compromise of information. Injection attacks allow an attacker to inject code into a program or query or inject malware onto a computer to execute remote commands that can read or modify a database, or change data on a website. These attacks include buffer overrun, XML, JavaScript, and HTML injections. ALGs with anomaly detection must be configured to protect against unauthorized code injections. These devices must include rules and anomaly detection algorithms to monitor for atypical database queries or accesses. Examples include Web Application Firewalls (WAFs) or database application gateways.

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. Verify the BIG-IP ASM module is configured to detect code injection attacks launched against application objects, including, at a minimum, application URLs and application code. Navigate to the BIG-IP System manager >> Local Traffic >> Virtual Servers >> Virtual Servers List tab. Select Virtual Servers(s) from the list to verify the configuration of an ASM policy to detect code injection attacks. Navigate to the Security >> Policies tab. Set "Policy Settings" to "Advanced". Verify that "Application Security Policy" is Enabled and "Policy" is set to use an ASM policy for the virtual server. Navigate to the BIG-IP System manager >> Security >> Application Security >> Security Policies. Select the Security Policy that has been assigned to the Virtual Server(s). Verify "Enforcement Mode" is Transparent or Blocking. Click "Attack Signatures Configurations" for "Signature Staging" under the "Configuration" section. Review the list under "Assigned Signature Sets" for the following signatures: Generic Detection Signatures Custom Systems Signature Set (based on systems identified in the application make-up). Verify the "Assignment Signature Sets" listed above have the "Alarm" button checked. If the BIG-IP ASM module is not configured to detect code injection attacks launched against application objects, including, at a minimum, application URLs and application code, this is a finding.
