When managing files and directories in a Linux environment, traditional Unix permissions (read, write, execute) offer a foundational level of security. These permissions determine access for the owner, group, and others. However, these conventional permission setups can sometimes fall short when you need more granularity and flexibility. This is where Access Control Lists (ACLs) come into play, offering a more nuanced approach to permissions and access rights on Linux systems. Access Control Lists (ACLs) are a feature of the Linux filesystem that allows you to apply detailed permissions to files and directories beyond the scope of standard Unix permissions.
