CIS Controls 5.2: Use Unique Passwords for Enterprise Assets
Weak or reused passwords are a primary attack vector for unauthorized access across your organization. CIS Controls 5.2 requires unique passwords for every enterprise asset—a foundational defense that prevents credential compromise from cascading across systems. Implementing this control with proper character length requirements significantly reduces breach risk.
What this means
CIS Controls 5.2 mandates that every enterprise asset uses a unique password with minimum character requirements based on multi-factor authentication status. Assets protected by MFA require passwords of at least 8 characters, while accounts without MFA require 14-character passwords to compensate for the additional risk. This ensures that if one password is compromised, attackers cannot access other systems or accounts.
How to comply
- 1.Establish a password policy requiring unique passwords for all enterprise assets and accounts
- 2.Set minimum password length to 8 characters for accounts protected by MFA
- 3.Set minimum password length to 14 characters for accounts without MFA enabled
- 4.Deploy a password manager or centralized identity management system to enforce uniqueness
- 5.Conduct an audit of existing accounts to identify and remediate reused passwords
- 6.Train employees on password best practices and the risks of password reuse
- 7.Monitor and enforce policy compliance through automated password policy controls
- 8.Regularly review access logs to detect unauthorized access attempts from credential compromise
Evidence auditors look for
- Password policy documentation specifying unique password requirements and character minimums
- Audit report showing all enterprise assets and accounts maintain unique passwords
- Identity management system configuration enforcing 8-character minimum for MFA-protected accounts
- Identity management system configuration enforcing 14-character minimum for non-MFA accounts
- Employee training records on password management and reuse risks
- Access logs demonstrating detection and response to potential credential compromise incidents
- Configuration screenshots from Active Directory, SSO, or password manager showing policy enforcement
