Ensure that your vRealize Automation deployment uses strong TLS protocols to secure transmission channels for Infrastructure as a Service components.
Secure Sockets Layer (SSL) and the more recently developed Transport Layer Security (TLS) are cryptographic protocols that help ensure system security during network communications between different system components. As SSL is an older standard, many of its implements no longer provide adequate security against potential attacks. Serious weaknesses have been identified with earlier SSL protocols, including SSLv2 and SSLv3. These protocols are no longer considered secure.
Depending on your organization’s security policies you may wish to also disable TLS 1.0.
When terminating TLS at the load balancer, also disable weak protocols such as SSLv2, SSLv3, as well as TLS 1.0 if required.
