University of Toronto ☛ We don't know what's happening on our networks
In some organizations, a foundational principle of their network security (both internal and external) is that you should know about everything that is happening on the network. No program, no network service, no system should be accepting or sending unknown network traffic, and you should be able to completely inventory your expected traffic patterns. In some environments, this will include not just protocol level knowledge but also things like what DNS names should be being looked up. This detailed knowledge is obviously great for network security and for detecting intrusions; unexpected network traffic can be used to trigger investigations and maybe alerts.
