Description

Mihai says: "We, as Linux users, have a wrong perspective about this OS, we think it's bulletproof by itself, although the ugly truth it's completely different. This course is one of the best ways to get to know Linux for real and its' security flaws. Congrats for the instructor, Carmen Balan, for the initiative."

Giussepe says "Clear explanation, simple but quite complete on may aspects of complex linux hardening job."

Leela says "Explained the concepts in a simplified manner."

Linux Servers provide many user transactions, which are constantly vulnerable to security threats, due to data sensitivity. To bring an application up and running on a server is an important thing, but without taking security measures, it can end up in a disaster. Although Linux is immune to some of the dangers Windows servers encounters, Internet is still a dangerous place. Therefore it's important to apply security measures to prevent malicious attacks like brute force attack, etc. 

This course was designed to show some practical tips on how to protect your server, that once applied, they will increase the level of security on your system and decrease the chances of it being compromised. 

Along with the video lectures, you will also find exercises to help you improve your hands-on experience. You will benefit for free from any new lectures and updates on the course.

Carmen explains the Linux security basics well, and at a steady pace. I would like to see more exercises so we can practice, and tougher tests to confirm our knowledge and review any weaknesses

I think it was nicely done. Maybe you can add something about Tripwire and some more quizzes would be nice and I always think one big Quiz at the End going trough all topics helps the learning experience. Thanks that was useful :-)
