Course Description:

Red Hat Linux Networking and Security Administration (RH253) arms students with in-depth knowledge needed for the most essential Red Hat Enterprise Linux network services and access control mechanisms. This course covers core system administration and knowledge to use Linux as part of more complex services infrastructure. At the end of the course, participants will be able to set up a Red Hat Enterprise Linux server and configure its network services and security. Through the lectures and hands-on labs, this course exposes students to the competencies tested by the Red Hat Certified Engineer (RHCE) exam, which is given on the last day.
