The Smart Meter Security Agent (SecA) monitors consistency of grid data across the network in order to address threats without jeopardizing the end user privacy.
The SecA is a new decentralized solution for detect cyber-physical threats to CEI. Using SeCa, organizations can collect a) non-confidential data such as frequency, voltages, angles of voltages and rate of change of frequency for the smart grid; b) monitor data traffic with each external actors; c) monitor the health of applications and of critical files on local storage resources, by checking their hash value, the number of read-writes, the available free space and more; and d) send non-confidential data which is relevant from cyber-security point of view to a higher level of security applications where data is correlated with other grid data received from other Smart Meters, in order to assess data inconsistencies. These functionalities can be utilized to put in place an incident detection agent also capable to apply specific countermeasures.
The SecA is deployed on each Smart Meter and in the cloud as DSO Security Agent and as a Regional Centre Security Agent. It is enabled to protect the privacy of user data, in compliance with Regional and European laws and the Energy Authorities in different countries. .
It has been accepted and presented in the ETSI paper entitled: “CYBER: Increasing smart meter security”
