Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation and neutralization of special elements in query inputs, eliminating the root cause of the CWE-943 flaw that permits local DoS.

prevent

Limits the ability of a local user to exhaust resources via malformed queries, directly mitigating the resulting denial-of-service condition.

prevent

Restricts the privileges of local users so they cannot execute arbitrary or dangerous query constructs that trigger the vulnerability.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require parameterized queries and input neutralization to prevent query-logic injection.

detects

Security testing in development catches injection vulnerabilities before release but does not itself implement the fix.

prevents

Secure development life cycle mandates input validation and query parameterization that directly prevent injection flaws.

prevents

Application security requirements explicitly call for controls against injection and improper query construction.

prevents

Secure architecture principles reduce the likelihood of query-logic flaws but do not prescribe the specific coding practice.

prevents

Secure coding standards require proper neutralization of special elements in all data queries.

prevents

Outsourced development agreements can require secure coding practices, indirectly mitigating the weakness.
