To protect against data mining, the BIG-IP ASM module must be configured to prevent 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 prevent attacks launched against organizational information from unauthorized data mining may result in the compromise of information. Injection attacks allow an attacker to inject code into a program or query or inject malware into 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. Compliance requires the ALG to have the capability to prevent code injections. 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 prevent code injection attacks from being 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 prevent 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 the "Enforcement Mode" is 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 "Assigned Signature Sets" listed above have the "Block" button checked. If the BIG-IP ASM module is not configured to prevent code injection attacks from being launched against application objects, including, at a minimum, application URLs and application code, this is a finding.
