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 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. Compliance requires the ALG to have the capability to prevent code injections. Examples include a Web Application Firewalls (WAFs) or database application gateways. Satisfies: SRG-NET-000318-ALG-000151, SRG-NET-000319-ALG-000153

ℹ️ Check
If the ALG does not perform content filtering as part of the traffic management functions, this is not applicable. From the BIG-IP GUI: 1. Security. 2. Application Security. 3. Security Policies. 4. Policies List. 5. Click the name of the policy. 6. Verify "Enforcement Mode" is set to "Blocking". 7. Select "Attack Signatures". 8. Click the filter at the top left of the signatures window. 9. Select "Buffer Overflow" in the "Attack Type" field and click "Apply". 10. Verify "Block" is checked for all signatures and "Status" is set to "Enforced". 11. Click the filter at the top left of the signatures window. 12. Select "Server Side Code Injection" in the "Attack Type" field and click "Apply". 13. Verify "Block" is checked for all signatures and "Status" is set to "Enforced". If the BIG-IP appliance is not configured to prevent code injection attacks launched against application objects including, at a minimum, application URLs and application code, this is a finding.
