Individual User Security Concerns

You should know who is in charge of the system you are using and where to report problems. This guide is not intended as a guide to UNIX System Administration, but the multi-user open environment of UNIX requires that you are familiar with some of the features of the operating system to prevent destruction of files and to prevent unauthorized access to your account.

• Use a Secure Logon Password

• Be Aware of Your File Access Permissions -- set umask appropriately.

• Don't erase files indiscriminately.

  Especially, do not erase files whose names begin with a dot (.)

• Verify that your files are backed up on a regular basis! Ask your system administrator about the standard backup procedure used on your system. VTAIX is backed up on a weekly basis.

• To preserve intersystem security, avoid use of '.rhosts' files

• Follow the designated system 'shutdown' procedure before turning the machine off.
