Docker Certified Associate Certification Training Course - MTLS (Mutual Transport Layer Security)

The video tutorial explains Mutual Transport Layer Security (MTLS) and its application in Docker Swarm. MTLS uses X509 certificates for mutual authentication between services, enhancing security by preventing impersonation. In Docker Swarm, MTLS is used to authenticate, authorize, and encrypt node communications. The manager node generates root certificates and tokens for node addition, ensuring secure and legitimate connections. The tutorial also covers certificate verification, root CA generation, and certificate rotation, emphasizing the importance of maintaining secure communications within a Docker Swarm environment.
