Preventing Spoofing Programs

Intruders sometimes spoof, that is, imitate login or other legitimate programs to intercept passwords or other sensitive data. The Trusted Solaris environment protects users from hostile spoofing programs by displaying the Trusted Symbol, an unmistakable, tamper-proof icon at the bottom of the screen that is displayed whenever you interact with the trusted computing base (TCB).
