1. Purpose
The purpose of this Multi-Factor Authentication (MFA) Policy is to establish requirements for the use of multi-factor authentication to strengthen identity verification and reduce the risk of unauthorized access to organizational systems, applications, networks, cloud services, and information assets.
Passwords alone are vulnerable to compromise through phishing, credential theft, brute-force attacks, social engineering, malware, and credential reuse. Multi-factor authentication provides an additional layer of security by requiring multiple forms of verification before access is granted.
This policy establishes the organization’s requirements for implementing, managing, and maintaining MFA controls.
2. Scope
This policy applies to:
- All employees
- Contractors
- Consultants
- Temporary personnel
- Interns
- Third-party personnel with authorized access to organizational resources
This policy applies to access involving:
- Workstations
- Servers
- Cloud services
- Business applications
- Administrative systems
- Remote access solutions
- Virtual private networks (VPNs)
- Email systems
- Databases
- Identity management platforms
- Mobile applications
- Internet-facing systems
The policy applies to all organizationally managed identities and systems where MFA is supported.
3. Policy Statement
The organization shall implement multi-factor authentication for systems and accounts based on risk, business requirements, regulatory obligations, and the sensitivity of information being accessed.
MFA shall be required for privileged access, remote access, access to sensitive information, and access to critical systems whenever technically feasible.
Users shall successfully complete MFA verification before access is granted to protected resources.
4. Objectives
The objectives of this policy are to:
- Reduce the risk of unauthorized access.
- Protect against credential compromise.
- Strengthen authentication security.
- Support secure remote access.
- Protect sensitive and critical information.
- Support compliance requirements.
- Reduce account takeover risks.
- Improve overall organizational security posture.
5. Definitions
Multi-Factor Authentication (MFA)
An authentication mechanism that requires two or more independent authentication factors to verify a user’s identity.
Authentication Factor
A category of evidence used to verify identity.
Authentication factors generally include:
- Something you know (password or PIN)
- Something you have (security token or mobile device)
- Something you are (biometric characteristic)
Privileged Account
An account with elevated permissions capable of administering systems, modifying security controls, or accessing sensitive resources.
Adaptive Authentication
An authentication process that evaluates risk factors and may require additional verification based on user behavior, location, device, or other conditions.
Authentication Token
A physical or virtual device used to generate authentication codes or cryptographic responses.
