Securing Big Data from Eavesdropping Attacks in SCADA/ICS Network Data Streams through Impulsive Statistical Fingerprinting
This addresses security vulnerabilities in SCADA/ICS networks, particularly in healthcare, by providing a lightweight method to protect data streams without relying on heavy cryptographic protocols.
The paper tackles securing SCADA/ICS network data streams from eavesdropping by proposing Impulsive Statistical Fingerprinting (ISF) as an alternative to cryptographic solutions, achieving data obfuscation and conversion to HL7 format for secure healthcare systems.
While data from Supervisory Control And Data Acquisition (SCADA) systems is sent upstream, it is both the length of pulses as well as their frequency present an excellent opportunity to incor-porate statistical fingerprinting. This is so, because datagrams in SCADA traffic follow a poison distribution. Although wrapping the SCADA traffic in a protective IPsec stream is an obvious choice, thin clients and unreliable communication channels make is less than ideal to use crypto-graphic solutions for security SCADA traffic. In this paper, we propose a smart alternative of data obfuscation in the form of Impulsive Statistical Fingerprinting (ISF). We provide important insights into our research in healthcare SCADA data security and the use of ISF. We substantiate the conversion of sensor data through the ISF into HL7 format and define policies of a seamless switch to a non HL7-based non-secure HIS to a secure HIS.
