NPM, encryption, and the challenges ahead: Part 1 of 2
It’s interesting to observe how encryption and network performance monitoring (NPM) have evolved over time. When I first entered the networking industry right out of college, many applications sent passwords over the network in clear text, unencrypted. Since just about everyone’s PC was wired back to a repeater (i.e., not a switch), we could observe each other’s traffic with free packet analyzers and laugh.
