6.10.1.1. CFL-MTLS-001: mTLS Enforcement#

Severity: high | Category: mtls | Compliance: CIS 3.6

Mutual TLS ensures both the client and server authenticate. Without mTLS, any client can connect to the origin.

Remediation: Enable mTLS for sensitive API endpoints and origin connections.

6.10.1.2. CFL-MTLS-002: mTLS Certificate Rotation#

Severity: medium | Category: mtls

mTLS client certificates should be rotated regularly. Expired or stale certificates undermine the mTLS trust model.

Remediation: Implement a certificate rotation schedule and monitor certificate expiry dates.
