Counter-Illegal Entry Protocols
From Halopedia, the Halo wiki
By 2521, UNSC military operating systems had been standardized for over seventy years, leaving them vulnerable to hacking. This stood in contrast to the Outer Colony networks used by the Insurrectionists, which were much more diverse in composition and thus more difficult for the UNSC to penetrate. There were several incidents in which UNSC systems had been hacked by rebel forces, the most prominent being the destroyer UNSC Persephone. This prompted Dr. Halsey to create new security protocols for the UNSC.
Based on already existing translation algorithms, the CIEPs were created by Dr. Halsey primarily for use in third-generation smart AIs. This new crop of intellect would allow them to penetrate any system software. A side-effect of the protocol was that the AIs could learn to mutate and defend established UNSC operations systems from attacks.
To Dr. Halsey's chagrin, the Illegal Entry Protocols and Counter-Illegal Entry Protocols soon gained the nicknames "PIE" and "C-PIE", respectively, based on misspellings of their acronyms.
