The Linux Security Guide is designed to assist users of Linux in
learning the processes and practices of securing workstations and
servers against local and remote intrusion, exploitation, and
malicious activity. The 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
Linux can be both fully functional and secured from most common
intrusion and exploit methods.
