Warning: Before enabling Trusted Execution (TE) on an AIX system, you should be absolutely certain that the configuration is actually correct. Depending on the configuration, it’s quite possible to put the system into a state where it no longer functions!

To enable Trusted Execution, simply set the TE attribute of the TE policies to the value on:

# trustchk -p TE=ON
# 

Note: Case sensitivity is not important, “te=on” can be used just as well.
