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.

Now updated for Red Hat Enterprise Linux 5!

Goal

RHS333 trains people with RHCE-level competency to understand, prevent, detect, and properly respond to sophisticated security threats aimed at enterprise systems. The course equips system administrators and security professionals with the skills and knowledge to harden computers against both internal and external attacks, providing in-depth analysis of the ever-changing threat models as they pertain to Red Hat Enterprise Linux. RH333 builds on the security skills developed in other Red Hat training courses so that administrators can design and implement an adequate security profile for critical enterprise systems.

Prerequisites

• RH253 Red Hat Linux Networking and Security Administration
• RH301 RHCE Rapid Track Course (and RHCE Exam) or RHCE certification or equivalent work experience is required for this course.
• course participants should already know the essential elements of how to configure the services covered, as this course will be focusing on more advanced topics from the outset.

Audience

The audience for this course includes system administrators, consultants, and other IT professionals responsible for the planning, implementation, and maintenance of network servers. While the emphasis is on running these services on Red Hat Enterprise Linux, and the content and labs will assume its use, system administrators and others using proprietary forms of Unix may also find many elements of this course relevant.
