Abstract
The widespread use of information and communication technology in industrial control systems has exposed many cyber attacks to these systems. The first step in providing security solutions is to recognize the threats and vulnerabilities of a system at first. Therefore, in this work, after providing a general overview of the SCADA security, we provide a survey on actual cyber attacks from 2000 up to now. To be able to assess the risk of these attacks, we perform profiling them based on the target systems of the attack, the geographical area of it, the method used in the attack and its impact. This profiling provides a clear view of the most important security incidents in SCADA systems and could be useful in the defining suitable strategies for preventing and defending against the major SCADA security attacks.

Abstract
Industrial control systems (ICSs) which are used in critical infrastructure and other industries mostly use various communication protocols. Most of these communication protocols have various cyber security challenges and weakness that give the attackers the opportunity to gain to their malicious intentions. In this paper, we assess IEC 60870-5-104 protocols from security perspective which is used in the ICSs as telemetry communication. According to achievement of these goals, we have analyzed the IEC 60870-5-104 design phase carefully and used experimental test bed to identify the security threats and vulnerabilities and characterize the technical attacks. Finally we review the design of hardening mechanisms and their challenges.
