secsetup - Security features setup script (Enhanced Security)
The command is an interactive facility that allows you to toggle security features on your system. You must first have loaded the enhanced security subset onto your system before running the command.
The command allows you to configure your system either for security auditing, enhanced login, or any combination of those features. You can run while the system is in multiuser mode (however, you must reboot to cause the security level to change).
Because of the page table sharing mechanism used for shared libraries, the normal file system permissions are not adequate to protect against unauthorized reading. The command will ask users if they wish to disable segment sharing. Only the text part of the library, not the data segment, is shared in this way. If the user enters a '?' at the prompt displays information about the choices. If the segment sharing is already disabled, states that segment sharing is already disabled. The change in segment sharing takes effect at the next reboot.
Depending on the security features chosen, when completes you may need to replace your system's kernel and reboot the system.
NOTE: After is run, passwords that were originally entered with more than 8 characters will match a string with ONLY the first 8 characters.
The audit_setup(8) reference page describes how to set up audit.
