AWS Application Load Balancer (ALB) and Network Load Balancer (NLB) now support new TLS-based security policies that comply with RFC 9151 TLS server requirements for Commercial National Security Algorithm (CNSA) 1.0 suite requirements. These policies implement the cryptographic requirements defined by the US National Security Agency (NSA) for secure communications using TLS 1.2 and TLS 1.3 protocols. Customers who are required to meet CNSA 1.0 TLS security requirements can now use ALB and NLB with RFC 9151 compliant security policies.
