The Crux of NT Security - Phase 3

by Hal Flynn Sept. 1, 2017 via Symantec

In the previous article, we discussed how to secure individual NT hosts in preparation for placing them on a network connected to the Internet. We discussed the security in terms of layering at the host level. At this point, we'll begin to add to those layers by the way that we control, monitor, and filter communications. One of the main intents of this article is to strictly define communication parameters and protocols down to a few essential ones and then log those remaining to a very full extent. We also want to discuss exactly when, where, how, and in which direction(s) we want those protocols to flow.
