Information Security of Linux Operating Systems: Practicum on Information Protection

The book discusses practical and theoretical issues of configuring and applying the main security mechanisms of Linux family operating systems: user authorization, access control to objects, auditing, encryption, firewalling, information recovery and secure deletion, centralized management, limitations on the use of removable information media, organizing remote access, and much more. The examples provided in the book are as close as possible to real situations that administrators and information security specialists face in their work and contain detailed, step-by-step explanations of their execution, while the tasks for independent completion and self-check questions for each section will help to better grasp the material.

The book examines the main features of a large number of Linux operating systems: Astra Linux, ROSA Linux, RedOS, etc., but the main focus is on the use of the domestic operating system Alt Linux. To solve the tasks, in the overwhelming majority of cases, the command line interface is used, so the knowledge and skills acquired can be applied in practically any Linux family operating system.
