We all are aware of the permissions that we set using some helpful Linux commands like chmod, chown, chgrp etc. However, these default permission sets have some limitation and sometimes may not work as per our needs. Access Control Lists (ACL) in Linux. It is designed to assist with UNIX file permissions. ACL allows you to give permissions for any user or group to any disc resource. Use of ACL: Think of a scenario in which a particular user is not a member of group created by you but still you want to give some read or write access linux access control systems One standout comment by a quoted source that needs dissecting: Windows access control blows Linux out of the water In a Windows box, you can set accesscontrol mechanisms without a

Securing Linux with Mandatory Access Controls. The most wellknown of these projects is Security Enhanced Linux (SELinux), which was developed by the U. S. National Security Agency (NSA). The Rule Set Based Access Control (RSBAC) project, the Linux Intrusion Detection System (LIDS), and grsecurity are other popular projects with the same goal. linux access control systems Linux file access permissions are used to control who is able to read, write and execute a certain file. This is an important consideration due to the multiuser nature of Linux systems and as a security mechanism to protect the critical system files both from the individual user and from any malicious software or viruses.
