Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can uncover deserialization flaws before deployment.
Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.
Input validation directly stops deserialization of untrusted data by ensuring inputs are valid before processing.
Integrity verification tools can detect malformed or tampered serialized data after the fact.

PR.PS-02 addresses only post-deployment updates/patching and cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.
