10 Cybersecurity definitions - ISACA The term Cyber Security addresses the governance, management and assurance that go beyond standard information security. Cybersecurity focuses on specific, highly sophisticated forms of attack and covers the technical and social aspects of the attack. Many definitions exist for cybersecurity, and the term is often misunderstood. The official EU definition follows: Cyber Security commonly refers to the safeguards and actions that can be used to protect the cyber domain, both in the civilian and military fields, from those threats that are associated with or that may harm its interdependent networks and information infrastructure. Cyber Security strives to preserve the availability and integrity of the networks and infrastructure and the confidentiality of the information contained therein.

11 Cybersecurity definitions - ISACA ISACA defines Cyber Security as follows: The protection of information assets by addressing threats to information that is processed, stored and transported by internetworked information systems. In its Transforming Cybersecurity publication, ISACA further describes Cyber Security as follows: Cyber Security encompasses all that protects enterprises and individuals from intentional attacks, breaches and incidents as well as the consequences. In practice, Cyber Security addresses primarily those types of attack, breach or incident that are targeted, sophisticated and difficult to detect or manage. the focus of Cyber Security is on what has become known as advanced persistent threats (APTs), cyberwarfare and their impact on enterprises and individuals.

12 Cybersecurity definitions - ISACA Cyber Risk is an ever-present threat, defined as any risk of financial loss, disruption or damage to the reputation of the organization from some sort of failure to its information technology systems. (Institute of Risk Management) It is possible to identify some main risk categories: losses due to cyber crime and cyber terrorism and cyber sabotage accidental loss of your own or someone else s data physical loss of systems (Critical information infrastructure break down) liability for your information/data (business data, online activities, s, ) Moreover, Cyber Risk is the risk arising from Cyber Crime, defined by Canadian Law is as follows: Crimes in which the computer is the target of the criminal activity; Crimes in which the computer is a tool used to commit the crime, and; Crimes in which the use of the computer is an incidental aspect of the commission of the crime.

22 The Target Story (2014) Company background Founded in 1902 Second largest discount retailer in the US after Walmart Ranked 36 th on Fortune 500 (2013) 1,916 stores Revenue (2013) US$72.6 (Source: Wikipedia) The attack Attacked not the central systems of the company but Point Of Sales (PoS) systems. Targeted Windows OS used to acquire data from Card readers. The System perform data encryption in memory: the malware scans the machine memory for Credit Card data. Data is sent externally of the company Data is used for Card Cloning. Attack vector from external third party (Fazio Mechanical Service - FMS): Malware via Phishing to FMS No enterprise AV used Stolen credentials used to get inside Target systems via HVAC system of FMS in Target.

25 Cybersecurity Governance Governance over cybersecurity has a much wider scope than governance over information security, due to the multiple facets of cybercrime and cyberwarfare. The cybersecurity governance framework covers enterprise security, social elements and technology.
