You can configure a PowerExchange listener to use TLS network security when accepting connections from Linux, UNIX, and Windows client processes by using TLS protocol TLSV1_2, which is the default.
Network packets are encrypted using the IBM i GSK functions. Optionally, the listener can validate the x509 subject certificate on the client process.
Informatica recommends that you use TLS security instead of the PowerExchange Alternate Network.
