Restricting Access to Data in Files

Since the Solaris operating environment is a multiuser environment, file system security is the most basic security risk on a system. You can use the traditional UNIX file protection to protect your files. You can also use the more secure access control lists (ACLs).

After you have established login restrictions, you can control access to the data on your machine. You might want to allow some users to read some files, and give other users permission to change or delete some files. You might have some data that you do not want anyone else to see. Chapter 4, Securing Files (Tasks) discusses how to set file permissions.
