Welcome to the Red Hat Enterprise Linux Security Guide!
The Red Hat Enterprise Linux Security Guide is designed to assist users of Red Hat Enterprise Linux in learning the processes and practices of securing workstations and servers against local and remote intrusion, exploitation, and malicious activity. The Red Hat Enterprise Linux Security Guide details the planning and the tools involved in creating a secured computing environment for the data center, workplace, and home. With proper administrative knowledge, vigilance, and tools, systems running Red Hat Enterprise Linux can be both fully functional and secured from most common intrusion and exploit methods.
This guide discusses several security-related topics in great detail, including:
Firewalls
Encryption
Securing Critical Services
Virtual Private Networks
Intrusion Detection
The manual is divided into the following parts:
General Introduction to Security
Configuring Red Hat Enterprise Linux for Security
Assessing Your Security
Intrusions and Incident Response
Appendix
We would like to thank Thomas Rude for his generous contributions to this manual. He wrote the Vulnerability Assessments and Incident Response chapters. Thanks, Thomas!
