the most secure way to meet the requirements. TLS is a protocol that provides encryption and authentication for data in transit. ALB is a service that distributes incoming traffic across multiple EC2 instances. HIDS is a system that monitors and detects malicious activity on a host. ECDHE is a type of cipher suite that supports perfect forward secrecy, which is a property that ensures that past and current TLS traffic stays secure even if the certificate private key is leaked. By creating a listener on the ALB that does not enable PFS cipher suites, and using encrypted connections to the servers using ECDHE cipher suites, you can ensure that the HIDS agents can capture the traffic of the EC2 instance without compromising the privacy of the users. The other options are either less secure or less compatible with the third-party solution.
