What Is Trusted Extensions Software?

Trusted Extensions provides special security features for your system. These features enable an organization to define and implement a labeled security policy on an Oracle Solaris system. A security policy is the set of rules and practices that help protect information and other resources, such as computer hardware, at your site.

Security practices are recommended procedures for performing tasks.
