Linux Firewalls Attack Detection and Response


Linux Firewalls discusses the technical details of the iptables firewall and the Netfilter framework that are built into the Linux kernel, and it explains how they provide strong filtering, Network Address Translation (NAT), state tracking, and application layer inspection capabilities that rival many commercial tools. You'll learn how to deploy iptables as an IDS with psad and fwsnort and how to build a strong, passive authentication layer around iptables with fwknop.


System administrators need to stay ahead of new security vulnerabilities that leave their networks exposed every day. A firewall and an intrusion detection systems (IDS) are two important weapons in that fight, enabling you to proactively deny access and monitor network traffic for signs of an attack.

Topics Covered:

Passive network authentication and OS fingerprinting
iptables log analysis and policies
Application layer attack detection with the iptables string match extension
Building an iptables ruleset that emulates a Snort ruleset
Port knocking vs. Single Packet Authorization (SPA)
Tools for visualizing iptables logs

Perl and C code snippets offer practical examples that will help you to maximize your deployment of Linux firewalls. If you're responsible for keeping a network secure, you'll find Linux Firewalls invaluable in your attempt to understand attacks and use iptables-along with psad and fwsnort-to detect and even prevent compromises.

Web Hacking 101

With a Foreword written by HackerOne Co-Founders Michiel Prins and Jobert Abma, Web Hacking 101 is about the ethical exploration of software for security issues but learning to hack isn't always easy. With few exceptions, existing books are overly technical, only dedicate a single chapter to website vulnerabilities or don't include any real world examples. This book is different. Using publicly disclosed vulnerabilities, Web Hacking 101 explains common web vulnerabilities and will show you how to start finding vulnerabilities and collecting bounties.

Hack-X-Crypt (By Ujjwal Sahay)

This is basically a straight forward guide towards ethical hacking and cyber security.Computer hacking is the practice of altering computer hardware and software to carry out a goal outside of the creator‘s original intention. People who slot in computer hacking actions and activities are often entitled as hackers. The majority of people assume that hackers are computer criminals. They fall short to identify the fact that criminals and hackers are two entirely unrelated things.
