    systems weaknesses 4 distinct areas are identified (López, Setola, & Wolthusen, 2012, p. 216). • SCADA systems weaknesses • Process Network weaknesses • Control Centre weaknesses • Network Layer weaknesses SCADA system weaknesses result from the very nature of the system itself. Because SCADA is software it is inherently open to malicious attempts. There are a multitude of attacks that can be executed on the system that will cause various degrees of damage. For instance, unauthorized command execution, where lack of authentication enables attackers to insert commands into program execution routines sent to all linked systems. Another form of attack can come from SCADA-DOS. Similar to the unauthorized commands attacks the attacker can create Denial-of-Service by forging and sending meaningless SCADA packets resulting in system overload. Consequently, SCADA is networked which can allow for greater access of systems (López, Setola, & Wolthusen, 2012, p. 216-220). Process networks generate another area of concern when assessing security. The process network hosts the SCADA servers, thus it is conceivable that if a person acquired access to a SCADA server the ripple effect could quickly unfold. Unsanctioned entry at this level would enable an attacker to potentially take full control of one or more portions of the entire Power Systems. An OPC DOS can act as a bridge between the SCADA server and the Control Network resulting in a denial of service besides segregating two…

    especially the energy sector, receives a disproportionate share of attacks [9]. A cyber attack on CI could come from competitors, adversarial states, politically motivated terrorists/hacktivists, or disgruntled insiders. Attacks on CI may use techniques ranging from simple abuse of unprotected systems, to sophisticated exploits such as spear phishing emails (socially engineered tricks to fool users into downloading and or executing malware) as well as unpublished zero-day attacks on…

    exploits employed for economic or military advantage; cyber crime, cyber terrorism and threats to SCADA systems; meta-data collected and used by the private sector and public sector; and vulnerability assessments for mobile devices in the BYOD environment may seem to have little in common. However, each comes with security issues, policy controls to be implemented, and human factors that influence the recommended policies. With so many aspects requiring security, the challenge is to recognize…
