In Tron 2.0, Intrusion Countermeasure Programs or ICPs for short, are like the white blood cells of the computer world, designed to seek out and destroy any unauthorized presence within their digital realm of control. ENCOM's ICP's are commanded by the mighty Kernel -- military pun intended. Much like white blood cells, when they "see" someone or something that is damaging surrounding programs, they automatically try to derez the program. However, this can be a fault because they cannot tell the difference between a malicious program or an unharmful program or user; any program or user that is "unauthorized" (i.e. not allowed to be in that part of the computer) will be derezzed on sight.

All ICP's fight with a Identity Disk Primitive weapon at the very least. Some ICPs come equipped with shields that block any non-explosive projectile, while others wield a Sequencer disc.

ICPs have different color schemes depending on what system they are from. ENCOM ICPs have red circuitry, Internet ICPs have Blue circuitry, and ICPs from FCon have purple circuitry. The circuitry usually corresponds to the color scheme of the environment the ICP is in.

An ICP can call in for reinforcement from a Sec Rezzer. These devices spawn in additional ICP programs to help neutralize the threat. A program or user with the correct permissions can deactivate the sec rezzer.

They are likened to the guard programs the MCP used in the original Tron film, and it can be speculated that the guard programs were recycled as security programs (and later upgraded to ICPs) after the MCP was destroyed. This is similar to how the recognizers were put to use as transports after the MCP relieved them of more nefarious duties.
