alt Hacker NewsIf you're allowing direct https out, how are you stopping exfiltration?
Maybe https is routed through a monitoring proxy, but in the situation of allowing ssh the ssh wouldn't be going though one. So I still don't see the point of restricting outgoing ports on a machine that's allowed to ssh out.
You can't, reasonably. It's just a heuristic against many exploits using non-standard ports to avoid detection by proxies or traffic inspection utilities.
