PhasorSec: Protocol Security Filters for Wide Area Measurement Systems
The syntactic complexity of SCADA/ICS protocols along with the emphasis on availability has led to the increase in the prevalence of input-handling vulnerabilities in SCADA/ICS protocols. We present PhasorSec, a methodology to produce hardened implementations of the C37.118 protocol in Wide Area Measurement Systems. PhasorSec reduces latency by outsourcing input validation to a separate network ﬁlter that exhaustively validates C37.118 packets with respect to the speciﬁcation of the protocol. We evaluate PhasorSec in terms of CPU-time and development effort and demonstrate its resilience to the state-ofthe-art AFL fuzzer. Abstract is not available.
