Ensure that Db2 USS file system is protected

MediumLevel 1Manual reviewdb2-zos

Description

The USS file system that contains Db2 product code, such as the IBM Data Server Driver for JDBC and SQLJ, Db2 supplied Java classes, Db2 Java stored procedures support code, and native DLL libraries must be protected from unauthorized modifications or deletions. The USS file systems that contain system and product code must be restricted to authorized personnel and audited. Failure to protect can result in a loss of system services.

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

Starting with the directory with pathname /usr/lpp/db2x10 (where 'x' represents the release indicator) and for each of the sub-directories, issue the following command to review the directory and file permissions. ls -l [pathname]

How it is fixed

Fix method: Guidance or infrastructure patch

Issue the chmod command to change the access permission as needed.
