Trusted Execution is collection of features in AIX that can be applied to enhance (or specify) the degree of trust for applications running on AIX. Trust is a central concept for IT security. One might say that TRUST is a way of expressing how certain a user or administrator can be that malicious user(s) have not been able to access and modify applications, kernel extensions, or system configurations.
In other words, Trusted Execution provides the SA (system administrator) the tools
needed to specify executables, kernel executables and files that need
to be verified before they are used. Unlike the old TCB (trusted
computing base) methods, Trusted Execution verification occurs in
realtime - or runtime - when the (un)trusted object is accessed. Files that
do not meet verification standards/tests are not loaded/opened by AIX.

Trusted AIX - the future?
Good chance that it is, and the future is hard! The installation of TrustedAIX is easy enough - however, root is no more. You have to work from the three users isso, sa and so - for default accounts.
Below you will find some listings of the completion of the installation. But on login as sa and so I could not find any easy command I could perform (smit was a big blank). Login as isso, and then swrole ALL at least let me run some commands (lsrole, lsauth) - but still do not have any idea what I can do on this system.
Study Required!
