Ensure world writable directories have the SVTX bit set

CaoCấp 1Tự độngaix

Mô tả

The system is audited for world writable directories. World writable directories are considered as a common application component - usually a location for temporary files. An audit should be performed on the system to search for the presence of world writable directories. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.

Cách khắc phục

Phương pháp khắc phục: Hướng dẫn hoặc bản vá hạ tầng

Review the local mounted JFS/JFS2 filesystems using the following command to find all world writable directories missing the SVTX bit: find / $ -fstype jfs -o -fstype jfs2 $ -type d -perm -o+w ! -perm -1000 -ls If a directory must retain world writable access, ensure that SVTX bit is set so that users can only remove the filenames they own: chmod o+t ${dir} NOTE: This will leave existing modes while adding the SVTX (also known as sticky bit) to the directory. The documented meaning of the flag for directories is: Sets the link permission to directories. Otherwise, remove world-write permission - without modifying the other mode bits: chmod o-w ${dir}
