Course details
Becoming a master at using Security-Enhanced Linux (SELinux) can set you apart as a developer or DevOps engineer and open up new opportunities to grow your career. SELinux is a valuable addition to the standard Linux security options that makes your Linux distribution secure. This course demonstrates the basics of SELinux before diving deeper into more advanced topics such as Multi-Level Security (MLS), Multi-Category Security (MCS), managing SELinux with Ansible, and using SELinux in containerized environments. Along the way, test out your new SELinux skills in real time in the exercise challenges at the end of each section. This course is also a full resource for learners who want to thoroughly understand SELinux while preparing for any Red Hat Enterprise Linux-related exam.
