Assessing the Effectiveness of PCAT in Avoiding Process Anomalies in Water Treatment Plants
Gauthama Raman M R, Siddhant Shrivastava, Aditya P. Mathur
IEEE Transactions on Industrial Informatics, 2025
PCAT validates the commands a PLC sends, so rogue or mistaken commands get caught before they reach an actuator. This paper measures how early it catches command anomalies in a water treatment plant, and how it avoids disruptions and false positives, on the SWaT testbed.

Argus: An Orthogonal Defense Framework to Protect Public Infrastructure against Cyber-Physical Attacks
Sridhar Adepu, Siddhant Shrivastava, Aditya Mathur
IEEE Internet Computing, 2016
Argus, named after the hundred-eyed watchman: a defence framework for public infrastructure facing cyber-physical attacks. Results on a real testbed show attacks getting detected early.
