Linux, Part 4 of 5: Files and Security

Course description

Discover what it takes to manage a Linux system. Find out what a backup file consists of and how to both manually and automatically back up a system. Explore package management including YUM and RPM, and because security is a critical, discover how to implement proper security protocols. Finally, learn what options you have when it comes to file systems and discover which option is right for you.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.
