The problems with forcing regular password expiry

Key Points:

• The main threat identified is the ineffectiveness of regular password expiry in enhancing security, as it can lead to weaker password practices.
• Impacted systems include those relying on traditional password policies, which may inadvertently encourage users to create simpler, more predictable passwords when forced to change them frequently.
• Recommended actions include adopting more effective authentication methods, such as multi-factor authentication (MFA), and encouraging users to create strong, unique passwords without mandatory expiry.

MITRE ATT&CK: Not applicable

IOCs: None mentioned

The NCSC's shift in guidance highlights the need for SOC teams to reassess password policies and consider alternative security measures that promote stronger user behavior without the drawbacks of enforced regular expiry.
