8.5 Multi-factor authentication (MFA) systems are configured to prevent misuse.
This requirement focuses on ensuring that multi-factor authentication (MFA) systems are properly configured to prevent misuse, including protection against replay attacks, unauthorized bypassing, and other security vulnerabilities that could compromise the authentication process.
Sub-requirements:
8.5. Authentication for application and system accounts is managed securely.
Ensure that credentials for application and system accounts are securely managed, not hardcoded, and protected from unauthorized access.
Key Risks
Frequently Asked Questions
How should application and system account credentials be managed?
By using secure vaults, rotating credentials regularly, and avoiding hardcoded passwords.
Can service accounts use shared credentials?
No, each account should have unique, securely managed credentials.
What are the risks of hardcoded credentials?
They can be easily discovered and exploited by attackers.
How often should service account credentials be reviewed?
At least annually, and after any significant system changes.
How are credentials for system accounts protected?
By restricting access, using credential vaults, and monitoring usage.
Common QSA Questions
Can you show how service account credentials are managed?
Yes, we use a credential vault and have documented processes for rotation and access control.
How do you ensure credentials are not hardcoded in applications?
We perform code reviews and automated scans to detect and remediate hardcoded credentials.
How are system account credentials rotated?
We have automated processes and policies requiring regular credential changes.
