APT Attack Analysis in SCADA Systems

SCADA (Supervisory Control and Data Acquisition) systems play a significant role in ICS (Industrial Control System). Safety, security and stable operation is crucial to the SCADA system. However, SCADA system currently faces many security threats, of which the most harmful is the APT attack. This paper analyzes the attack surface and its own vulnerabilities of SCADA system, and analyzes the characteristics of APT attack comprehensively. Then the paper dissects the cases of real APT attack thoroughly and gives measures of SCADA security protection.
