Linux Network Security

by David Clinton

The need to reliably connect your computers to larger public networks has never been greater. But neither have the risks. This course will teach you how to build both active and passive protection into your network infrastructure.

What you'll learn

Whether you're providing enterprise-level services over the web or a company intranet, or simply trying to protect the applications running in your local data center, your network represents your first line of defense against external attacks on your infrastructure. This course, Linux Network Security, will cover the very best security software and practices available to Linux admins, including FreeRADIUS, Wireshark, OpenVAS, iptables, and OpenVPN. You will start with understanding the threats and the tools you can use to counter them. You'll continue with seeing how to configure and deploy Linux firewall servers using Netfilter and iptables as well as securing your network connections reliably through encrypted virtual private networks. After completing this course, you'll be better prepared to successfully monitor network activity, scan for vulnerabilities, and protect the legitimate use of your hardware.
