Title: Overall a respectable security reference for Linux sysadmins
Review: [I'm adding this review because as of this writing there are only two other reviews, and I am not sure either is particularly helpful.]As someone else mentioned, some of the distro-specific implementation details in this book are indeed dated. But the key ideas are all here for one to build and implement a security plan, and that is what counts.Covered are such basic concepts as: packet filtering, shutting off/removing unneeded services, disaster recovery, software management, and others. It's surprising to me how many folks I run into who don't understand these critical areas.4 out of 5 stars: respectable Linux security beginner book with lots of (sometimes extraneous, occasionally outdated) information.
