A few months ago, my library gained a copy of Cybersecurity For Small Networks by Seth Enoka, published by No Starch Press in 2022. So I figured I’d have a look and see if it it included modern best-practices for networks.

It was alright, in that it’s a decent how-to guide for a novice to set up sensible, minimum network fortifications. But it only includes an overview of how those fortifications work, without going into the additional depth needed to fine-tune or optimize them for specific environments. So if the reader has zero experience with network security, it’s a worthwhile read. But if you’ve already been operating a network with defenses for a while, there’s not much to gain from this particular text.

Also, the author suggests that IPv6 should be disabled, which is a terrible idea. Modern best-practice is not to pretend IPv6 doesn’t exist, but to assure that firewalls and other defenses are configured to handle this traffic. There’s a vast difference between “administratively reject IPv6 traffic in/out of the WAN” and “disable IPv6 on all devices and pray no one ever connects an IPv6-enabled device”.

You might have a look at other books available from No Starch Press, though.
