The session will also delve into the foundational knowledge of cybersecurity, emphasizing the impact of threats on organizations and individuals. This will set the foundation for the rest of the module. ▪ Understanding the Need for Information Security Management ▪ Core Principles and Concepts of Information Security Management ▪ Foundational Knowledge of Cybersecurity ▪ Understanding the Impact of Cyber Threats on Organizations and Individuals ▪ Exploration of Common Security Threats ▪ Comprehension of Security Vulnerabilities ▪ Human Factor and its Role in Information Security 6  The Need for Information Security Management INTRODUCTION RISING CYBER-THREAT LANDSCAPE MOTIVATION BEHIND CYBERATTACKS ▪ What is ISM ▪ Evolution of Threats ▪ Financial gain ▪ The increasing reliance on digital ▪ Sophistications of cyber-attacks ▪ Political motivation systems + interconnectivity ▪ The increasing reliance on digital ▪ State actors Example: Critical Infrastructure systems + interconnectivity ▪ Corporate Espionage ▪ Insider threats Sectors: Communications, Energy, Example: Estonia (2007), Ukraine Financial, Transportation, Water (2015), Target (2013), Equifax (2017), ▪ Revenge ▪ Recognition & achievement management, etc. Colonial Pipeline (2021), Albania (2022), etc. OPERATIONAL CONTINUITY ▪ Importance of information security for uninterrupted business operations ▪ Examples of operational disruptions due to cyberattacks (Ransomware, DDoS, etc.) FINANCIAL IMPLICATIONS REPUTATIONAL DAMAGE LEGAL AND REGULATORY REQUIREMENTS ▪ Cost of security breaches to organizations ▪ Reputational impact due to security ▪ Consequences of non-compliance (forensics and remediations, compensations incidents ▪ GDPR, HIPAA, latest SEC requirement, etc. to affected parties) ▪ Trust and brand loyalty ▪ Investment in proactive security measures considerations vs. reactive measures 7  The Need for Information Security Management Key Takeaways ESSENTIAL FOR ORGANIZATIONAL PROTECTION ▪ Fundamental in safeguarding organizational assets against diverse cyber threats. ▪ Critical in ensuring the confidentiality, integrity, and availability of data. IMPACT EXTENDS BEYOND THE ORGANIZATION ▪ Poor security management affects not just the organization, but also its customers, partners, and potentially the wider public. ▪ Can lead to financial, reputational, and legal consequences on a larger scale. SHARED RESPONSIBILITY ▪ Effective security is a collective effort, involving every individual in the organization. ▪ Not limited to the IT department; requires engagement from all levels, including management and staff. LEADERSHIP 'S PIVOTAL ROLE ▪ Leadership must champion a security-focused organizational culture. ▪ Responsible for allocating necessary resources for robust security measures and training. A CONTINUOUS AND ADAPTIVE PROCESS ▪ Information security is not a one-time effort but an ongoing process. ▪ Requires constant vigilance, regular updates, and adaptation to emerging threats and technologies. 8  Core Principles of Information Security Management Introduction to the CIA Triad CONFIDENTIALITY INTEGRITY AVAILABILITY Ensuring that information and resources are Ensuring that sensitive information is accessed Guaranteeing the accuracy and completeness of available to those who need them, when they only by authorized individuals. data. need them.

Importance: Tracing actions back to the source, ensuring responsible use. Tools: Digital signatures, audit trails.

Methods to ensure confidentiality include data encryption, identity proofing and two factor authentication. INTEGRITY Ensures that system information or processes are protected from intentional or accidental modification. One way to ensure integrity is to use a hash function or checksum. AVAILABILITY Availability means that authorized users are able to access systems and data when and where needed and those that do not meet established conditions, are not.

The Security Measures Used to Protect Data AWARENESS, TRAINING AND TECHNOLOGY POLICY AND PROCEDURES EDUCATION Refers to the software- and Refers to the administrative Measures put in place by an hardware-based solutions controls that provide a organization to ensure that designed to protect information foundation for how an users are knowledgeable about systems such as firewalls, which organization implements potential security threats and continuously monitor your information assurance, such as the actions they can take to network in search of possible incident response plans and protect information systems. malicious incidents. best practice guidelines. 11  Foundational Knowledge of Cybersecurity ▪ Cybersecurity Is the application of technologies, processes, and controls to protect systems, networks, programs, devices and data from cyber attacks. It aims to reduce the risk of cyber attacks and protect against the unauthorized exploitation of systems, networks, and technologies. ▪ Why is cybersecurity Important THE COSTS OF CYBER SECURITY CYBER ATTACKS ARE INCREASINGLY CYBER CRIME IS A BIG BUSINESS CYBER SECURITY IS A CRITICAL, BREACHES ARE RISING SOPHISTICATED BOARD-LEVEL ISSUE According to a study by McAfee and New regulations and reporting Organizations that suffer cyber Cyber attacks continue to grow in requirements make cyber security the CSIS, based on data collected by security breaches may face sophistication, with attackers using risk oversight a challenge.

These include social management that its cyber risk considered, like reputational engineering, malware and year due to cybercrime.
