Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation and neutralization of command arguments to block CWE-88 argument injection before it reaches the DD OS command processor.

prevent

Enforces least privilege so a low-privileged remote account cannot supply or influence arguments that trigger DoS in privileged command paths.

prevent

Requires mechanisms that limit resource exhaustion and DoS effects resulting from successful argument injection against the Data Domain appliance.

prevents

Secure SDLC practices directly require proper input validation and command construction to prevent argument injection.

detects

Security testing can detect argument injection but does not prevent it at the source.

prevents

Secure development lifecycle mandates input validation and command construction practices that directly prevent argument injection.

prevents

Application security requirements include explicit rules for safe command-line argument handling and escaping.

prevents

Secure architecture principles discourage unsafe command invocation patterns and favor safer APIs.

prevents

Secure coding standards explicitly require proper neutralization of command arguments, directly eliminating CWE-88.

none

Change management can catch unsafe command patterns during reviews but is not a direct mitigation.
