FAQs

This checklist covers cryptographic policy development, algorithm selection, key generation and storage, key rotation practices, secure key distribution, and cryptographic system monitoring and auditing.

By ensuring proper implementation of cryptographic controls and effective key management, organizations can significantly improve the security of their sensitive data, both at rest and in transit.

The audit process should involve information security officers, cryptography specialists, system administrators, compliance officers, and representatives from teams handling sensitive data or managing cryptographic systems.

Cryptographic policies and key management practices should be reviewed at least annually, with more frequent reviews when there are significant changes in technology, threats, or regulatory requirements.

Yes, this checklist can support compliance with industry-specific regulations that require strong encryption, such as PCI DSS for financial services or HIPAA for healthcare, by ensuring robust cryptographic practices are in place.
