ELBSecurityPolicy-FS-1-2-2019-08 gives customers the option of only using the TLS 1.2 protocol with the same set of ciphers as available with ELBSecurityPolicy-FS-2018-06. The ciphers in this policy ensure Forward Secrecy, preventing out-of-band decryption if someone records the traffic and later compromises the server’s private key. Additionally, ELBSecurityPolicy-FS-1-1-2019-08 is available for customers wanting to use a more permissible Forward Secrecy policy supporting both 1.1 and 1.2 clients.
ELBSecurityPolicy-FS-1-2-Res-2019-08 is the most restrictive policy available till date, helping customers achieve any stringent security requirements. This policy supports TLS 1.2 only and includes only ECDHE (PFS) and SHA256 or stronger (384) ciphers.
