Security concept

This section describes how POSIX was embedded into BS2000 in order to ensure the security of the overall system. The necessary functions were partly ported with the UNIX system kernel, and they are also partly a component of the BS2000 module SRPM (System Resources and Privileges Management). For more information on SRPM, please refer to chapter “Administering POSIX users”.

The security concept covers:

• user data administration

• group administration

• access protection for container files

• access protection for files and directories

• access protection for access via remote computer
