This course is intended for Linux/Unix system and network administrators who want to learn about securing Red Hat Linux.
Delegates should already have some real-world experience with Red Hat Linux system and network administration. Attendance of our Linux System Administration (Red Hat/SUSE & Debian) and Linux Enterprise Server for Experienced UNIX Administrators courses would be beneficial.
2 days. Hands on.
This course is available on site only. Please call for details.
This course provides delegates with the knowledge and skills necesary to secure RHEL5 at the system and network levels. This highly-practical course covers Red Hat Enterprise Linux (RHEL5), but much of the material is also relevant to earlier versions.
After completing this course, students will be able to:
- Explain Security concerns and policy.
- Configure authentication Services.
- Secure the system.
- Secure Networks.
- Secure Services.
- Secure Data.
Please Note: This course is designed to impart technical information to the delegates. It is not designed to teach audit techniques, standards or remedial plans.
