NIST SP 800-53 Control Identifier Regex for JavaScript

What this pattern does

This page provides a comprehensive, battle-tested regular expression for matching nist sp 800-53 control identifier, ported and verified for JavaScript. In security-sensitive code, using an unverified regex can open the door to both false positives and denial-of-service attacks. The snippet below is ready to drop into your JavaScript project — whether you're validating in an Express middleware, a Next.js API route, or a client-side form.

Javascript Implementation

// NIST SP 800-53 Control Identifier
// ReDoS-safe | RegexVault — Security > Audit & Compliance

const nistSp80053ControlIdentifierRegex = /^(AC|AT|AU|CA|CM|CP|IA|IR|MA|MP|PE|PL|PM|PS|PT|RA|SA|SC|SI|SR)-([0-9]{1,2})(?:\s*\(([0-9]{1,2})\))?$/i;

function validateNistSp80053ControlIdentifier(input: string): boolean {
  return nistSp80053ControlIdentifierRegex.test(input);
}

// Example
console.log(validateNistSp80053ControlIdentifier("AC-1")); // true

Test Cases

When to use this pattern

This pattern is drawn from the Security > Audit & Compliance category and carries a ReDoS-safe certification. That matters for JavaScript developers because especially critical in long-running Node.js event loops where a ReDoS vulnerability can block the entire process. RegexVault audits patterns against known backtracking attack vectors, ensuring you have the necessary context before using this regex in a high-stakes production environment.
