Modules, Upgrades, and Countermeasures


Countermeasures form a computer system’s last defense against hackers trying to compromise it. Countermeasures are specifically designed to activate when an unauthorized user attempts unsuccessfully to access the system, usually by entering an incorrect password or by failing to bypass other security precautions. Some activate the moment a user tries to get into the system and deactivate only once the correct password has been entered. In either case, a computer can have a number of countermeasures equal to its tier.

Fake Shell

Price 50% of computer's base price + 10% of price of control and data modules; Type Countermeasure
This particularly cunning countermeasure creates an entirely fake network and system directory for anyone accessing the system that fails to bypass this countermeasure. The phony network has cloned control modules and data modules to make it appear to be the actual system, but the control modules do not actually work and the data modules contain garbage files. A character can uncover this ruse with a successful Computers check with a DC equal to the system’s DC + 5. You automatically get a new check each minute with a cumulative +2 circumstance bonus until you discover the ruse. The fake shell countermeasure costs 50% of the base price of the computer plus 10% of the price of its control and data modules.
