Troubleshooting issues with cryptographic implementations
In an enterprise-supporting PKI implementation, we can expect to see issues where there are compatibility, configurational, and operational problems that cause communication to be disrupted or executed insecurely. It is important to recognize where these problems could occur and look to mitigate them through effective policies and procedures.
Key rotation
It is important to recognize the benefits of key rotation to ensure data confidentiality is maintained. Keys can be rotated automatically or manually, based upon the organization's policies, or may be dictated by regulatory compliance. If a key is compromised, then it should be revoked immediately. The Payment Card Industry Data Security Standard (PCI DSS) requires that keys are rotated on a regular basis, based upon the number of records or transactions that have been encrypted.
