Description:

Red Hat Enterprise Linux has gained considerable momentum as the operating system of choice for deploying network services such as web, ftp, email, and file sharing. RHS333 Red Hat Enterprise Security: Network Services is an intensive course that provides four days of instruction and labs on how to to use the latest technologies to secure your services.

Target Audience:

The audience for this course includes system administrators, consultants, and other IT professionals responsible for the planning, implementation, and maintenance of network servers.
