Mitigating Controls (NIST 800-53 r5) AI

CM-6 Configuration Settings good match

Secure baseline settings can enforce absolute, organization-controlled paths for critical resources.

CM-7 Least Functionality partial match

Least-functionality configuration can prohibit unapproved directories or executables from being reachable via search paths.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles such as trusted paths, complete mediation, and least privilege directly require hard-coded or validated search paths instead of external ones.

SC-39 Process Isolation partial match

Maintaining separate execution domains for each process structurally eliminates unintended concurrent access to the same shared resources.

SC-4 Information in Shared System Resources partial match

Preventing unintended information transfer through shared system resources directly addresses the improper concurrent modification that defines a race condition.

PR.PS-05 full match
prevents

Preventing execution of unauthorized code directly blocks the malicious binaries that an untrusted search path would load.

PR.PS-06 mostly match
prevents

Secure development practices include avoiding or sanitizing externally influenced search paths in application code.

PR.PS-01 partial match
prevents

Hardened configuration baselines can enforce safe search paths and restrict environment variables that enable the weakness.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can discover search-path issues but does not itself prevent them in production code.

A.8.19 Installation of software on operational systems partial match
degrades

Restricting software installation reduces the chance that untrusted binaries or libraries are placed in search paths.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates concurrency controls and synchronization primitives that directly prevent race conditions.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify thread-safety and locking rules, but do not prescribe implementation details.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles include hard-coded or validated search paths and avoiding reliance on untrusted directories.

A.8.28 Secure coding partial match
prevents

Secure coding standards require absolute paths or integrity-checked search paths, directly mitigating CWE-426.
