Mastering Linux Security and Hardening Third Edition

My Mastering Linux Security and Hardening book has been a best seller from the beginning. Now, in Mastering Security and Hardening Third Edition, you'll find lots of updated content that applies to the newest Red Hat 9 and Ubuntu 22.04 Linux distros, and a few tidbits of information about the newest SUSE distros. There's also new content that you won't find in the older editions, such as how to set up two-factor authentication and how to prevent unwanted programs from running on your systems. So, be sure to check it out.

In your vid: All is brown. The car is brown. The book-cover is brown. That's OK. But, SUSE-Green is more beautiful. Green symbolizes sustainability. (Happy with SUSE since 2001.)

I Like your books, They are usually up to date and they are not like other books. These days most of the books are just copy-paste of tools documents, but yours(at least the ones I've read) are not like them.
