Using Access Control Lists to Protect UFS Files

Traditional UNIX file protection provides read, write, and execute permissions for the three user classes: file owner, file group, and other. In a UFS file system, an access control list (ACL) provides better file security by enabling you to do the following:

Note - For ACLs in the ZFS file system and ACLs on NFSv4 files, see Chapter 7, Using ACLs and Attributes to Protect Oracle Solaris ZFS Files, in Oracle Solaris 11.1 Administration: ZFS File Systems.

For example, if you want everyone in a group to be able to read a file, you can simply grant group read permissions on that file. However, if you want only one person in the group to be able to write to that file, you can use an ACL.

For more information about ACLs on UFS file systems, see System Administration Guide: Security Services for the Oracle Solaris 10 release.
