This is a multiple-response question, and all options contribute significantly to improving content pack security and preventing arbitrary command execution vulnerabilities. -A (Input Validation/Sanitization): Directly addresses common vulnerabilities like command injection by ensuring untrusted input cannot be executed as code or used to manipulate file paths. - B (Container Isolation/Least Privilege): XSOAR integrations run within containers. Ensuring these containers have minimal necessary privileges (e.g., read-only access to specific directories) and resource limits (CPU, memory) significantly limits the blast radius of a successful exploit. - C (Code Audits/SAST/DAST): Proactive security testing is crucial to identify vulnerabilities in the code itself before deployment. SAST can find common code flaws, and DAST (if applicable, for web-facing integrations) can test runtime vulnerabilities. - D (Execution Whitelisting): This XSOAR feature allows administrators to explicitly define a whitelist of allowed commands and scripts, preventing unauthorized execution even if a vulnerability allows an attacker to attempt it. - E (Patching OS/Dependencies): A fundamental security hygiene practice. Even if your content pack code is perfect, vulnerabilities in the underlying OS or its libraries (e.g., Python runtime, network libraries) can be exploited to gain control.
