20.10 SUDO

Sudo is a public domain software program. It provides a layer of control on the use of root user privileges available during a session. The root account is the only account on the system with unrestricted privileges. If a security policy is adopted and requires a mechanism that restricts the root user privileges, Sudo is a program adopted by many UNIX system administrators. Advantages of Sudo include:

• Selected root user privileges can be distributed as required to operators

• The root password is not required to execute commands with Sudo

• Commands executed via Sudo are logged

• Root user privileges can be revoked without changes to the root password

• Privileged users and their privileges are maintained in a secure list
