Correct answer: Parameter Data Types and Attack Signatures

Injection flaws occur when untrusted data is sent to an interpreter as part of a command or query. BIG-IP ASM mitigates this primarily through strict Parameter Data Type enforcement (positive security model) and specific Attack Signatures (negative security model) that detect SQLi, Command Injection, and XPATH injection patterns.

Correct answers: It helps reduce false positives by correlating scanner findings with existing ASM attack signatures.; It allows ASM to create virtual patches by automatically generating rules to mitigate identified vulnerabilities.

The integration correlates the vulnerabilities found by the scanner with the protections available in ASM, resolving security gaps and accurately applying only the necessary mitigations, which streamlines policy management and reduces false positives.

Integrating a DAST tool (like WhiteHat, Qualys, or IBM AppScan) with ASM allows the system to parse the vulnerability report and automatically generate 'virtual patches'—specific ASM rules and attack signatures to block exploits targeting the discovered flaws.

Correct answer: Deploy a Comprehensive policy template using Automatic Policy Builder in transparent mode during a QA testing phase, then switch to blocking mode prior to launch.

For a stable application requiring a strict positive security model (explicit URLs, parameters, file types), a Comprehensive policy is required. Since manual definition is impossible due to staff constraints and timeline, using the Automatic Policy Builder during a rigorous QA/testing phase allows ASM to learn the expected traffic patterns automatically. Switching to blocking mode before launch meets the strict security mandate.

Correct answer: It increases the likelihood of false positives and requires higher administrative manageability.

Implementing a strict positive security model (granular parameters, strict lengths, specific data types) significantly increases security but directly increases the risk of false positives if users submit valid but unexpected data. This approach also requires higher administrative effort (manageability) to maintain as the application evolves.

Correct answer: False

False. Applications with a high rate of change are poorly suited for manually built Comprehensive policies because the constant updates would generate massive amounts of false positives and require unmanageable administrative overhead. A Rapid Deployment policy or an automatically built policy is far more appropriate.

Correct answer: It provides tighter security by ensuring a parameter is only allowed on the specific URL where it is expected.

Per-URL parameter definition provides a much tighter positive security model. A parameter named 'id' might be expected as an integer on '/view_profile.php' but as an alphanumeric string on '/search.php'. Global parameters apply the same rules everywhere, whereas per-URL parameters restrict the parameter strictly to the endpoint that requires it.
