Book Description
The Definitive Guide to Building Firewalls with Linux
As the security challenges facing Linux system and network administrators have grown,the security tools and techniques available to them have improved dramatically. In Linux® Firewalls,Fourth Edition,long-time Linux security expert Steve Suehring has revamped his definitive Linux firewall guide to cover the important advances in Linux security.
An indispensable working resource for every Linux administrator concerned with security,this guide presents comprehensive coverage of both iptables and nftables. Building on the solid networking and firewalling foundation in previous editions,it also adds coverage of modern tools and techniques for detecting exploits and intrusions,and much more.

If you’re a Linux professional,it will help you establish an understanding of security for any Linux system,and for networks of all sizes,from home to enterprise.
