The Tandem Security System
The Tandem NonStop Kernel operating system and its utilities offer basic system
protection.
The security software product Safeguard extends security features to include auditing,
extended access-control, authentication features, and segregation of administrative tasks.
If you are using the OSS environment, you must use the Safeguard software to define
users for your system.
If you use NonStop SQL/MP, a relational database management system, you can extend
security features even further.
In addition, Tandem supports a message interface to a command-interpreter monitoring
process called $CMON. $CMON allows you to control and track logon attempts and
important security changes. Figure 9-2 shows the layers of Tandem security.
