Description

Linux is the first choice for any attacker now and more administrators have started moving to the system to create networks or servers for any task. This course will help you create a more secure Linux system.This comprehensive 2-in-1 training course you’ll explore some of the techniques that the expert hackers use in order to scan a website, and server, in order to carry out their intrusion attacks. Also get to perform a number of advanced Linux security techniques such as network service detection, user authentication, controlling special permissions, encrypting file systems, and much more.
Contents and OverviewThis training program includes 2 complete courses, carefully chosen to give you the most comprehensive training possible.The first course, Linux Server Security, introduces various techniques that professional hackers use in order to scan a website and a server, in order to carry out their intrusion attacks. Learn to create secure accounts where you'll look into deleting and creating user accounts password and monitoring servers. Further you’ll learn to maintain your Linux Server in order to get optimized performance and stability. Moving ahead, focus on tools that can be used to enhance server security, understand the art of hardening passwords, and fix authentication failures.The second course, Mastering Linux Security and Hardening, shows you various security techniques such as SSH hardening, network service detection, setting up firewalls, encrypting file systems, protecting user accounts, authentication processes, and so on. Moving forward, you’ll also develop hands-on skills with advanced Linux permissions, access control, special modes, and more. Lastly, this course will also cover best practices and troubleshooting techniques to get your work done efficiently.By the end of this Learning Path, you’ll have mastered the art of preventing your Linux system from getting compromised.
