Description: User account and permission management in UNIX-based operating systems is a fundamental aspect of managing these environments. This management involves creating, modifying, and deleting user accounts, as well as assigning permissions and roles that determine access to system resources. Administrators use specific tools and commands, such as ‘useradd’, ‘usermod’, and ‘userdel’, to efficiently handle these accounts. Additionally, user management includes configuring groups, which allows organizing users into sets with common permissions, thus facilitating the management of access to files and directories. Security is a critical aspect of this management, as appropriate policies must be established to protect sensitive information and ensure that only authorized users can access certain resources. User management not only focuses on account creation but also on auditing and tracking user activities, allowing administrators to maintain control over system usage and detect potential security breaches.
