DEPENDABILITY AND VULNERABILITY OF SCADA SYSTEMS

10.15660/AUOFMTE.2014-1.2982

Nicoleta IGNAT

Volume XXIII (XIII), 2014/1

In the last years, the security of critical infrastructures followed a decreasing trend due to the apparition of new cyber threats against Supervisory Control and Data Acquisition (SCADA) systems. As the increasing interconnections have made SCADA systems more vulnerable to attacks and risks, an emergent need to mitigate these risks appeared. While SCADA systems protection is extremely poor and needs to be upgraded to withstand cyber attacks of all forms, cyber security problem requires multidirectional approach considering many different aspects of vulnerabilities in the system. This paper analyzes the SCADA network vulnerabilities with respect to cyber security and tries to find countermeasures for the most common attacks.

Keywords: attack, measures, risks, SCADA systems, vulnerability
