IT Governance and Its Intersection with Business Information Security

Image
Introduction In 2026, IT governance is no longer a back-office function—it's a strategic imperative that directly shapes organizational resilience, digital trust, and competitive advantage. As enterprises accelerate AI adoption, cloud migration, and ecosystem dependencies, the intersection with business information security has become the linchpin: governance ensures security is embedded in strategy, risk decisions, resource allocation, and board oversight, while security provides the controls and evidence that make governance credible and defensible. Recent 2025 incidents such as AI-weaponized espionage campaigns (e.g., state actors using generative AI for autonomous attacks on critical infrastructure), massive supply-chain disruptions (UNFI ransomware halting food distribution, Ingram Micro ransomware impacting global channels), and credential compromises shutting down factories (e.g., Jaguar Land Rover's £1.9B hit) highlight governance failures: inadequate third-party ove...

Network Security Controls in IT Audit: Protecting Assets in a Connected World

Image
Introduction In our hyper-connected 2026 reality where IoT devices outnumber humans, cloud/hybrid environments dominate, and AI-powered attacks surge network security controls are the frontline defense against breaches that can cost millions and erode trust overnight. IT audits in 2025–2026 increasingly focus on verifying these controls' design , implementation , and operating effectiveness against evolving threats like ransomware lateral movement, supply-chain exploits, and zero-day vulnerabilities. Recent incidents underscore the stakes: The Change Healthcare ransomware attack (2024, impacting 190+ million records into 2025) exposed weak network segmentation and third-party access. PowerSchool's 2025 breach compromised 62 million student records via vendor vulnerabilities. Massive credential leaks (16 billion+ in mid-2025) highlighted poor access controls and monitoring. These events drive auditors to prioritize zero-trust architectures , micro-segmentation , continuous mon...

IT Disaster Recovery and Business Continuity: Lessons from Theory to Practice

Image
Introduction In an era where a single faulty update or ransomware attack can cost billions and disrupt global operations, IT Disaster Recovery (DR) and Business Continuity (BC) are essential for survival. The Crowd Strike outage in July 2024 (affecting ~8.5 million Windows systems worldwide) and multiple major cloud outages in 2025 (e.g., AWS US-East-1 region down for 15 hours in October, Google Cloud multi-service failure in June) exposed how fragile even the most advanced infrastructures can be. Ransomware attacks surged 52% in 2025, with healthcare and supply chains hit hardest—often causing patient care disruptions and operational halts. Understanding the Basics Business continuity focuses on maintaining operations during disruptions, while disaster recovery deals with restoring IT systems post-incident. Key metrics include Recovery Point Objective (RPO) the maximum data loss tolerable and Recovery Time Objective (RTO) the time to restore systems. A classic example is the 2017...

Introduction to IT Risk Management in Modern Enterprises

Image
Introduction In the current digital landscape of 2026, IT Risk Management is central to effective IT Audit and Control. As per our module's "IAC-IT Risk Management" content, it encompasses the Concept of Information Security, Risk Assessment, Asset Modeling and Valuation, Threat and Vulnerability Assessment, Measure of Risk (MOR), and Risk Treatment. From experiential learning in class, we've discussed how organizations face escalating threats like ransomware surges in 2025-2026, including major supply chain attacks (e.g., Cl0p exploits on Oracle systems and disruptions to global firms like Jaguar Land Rover). These align with emerging theories emphasizing proactive risk treatment amid AI-driven threats. Core Definition and Strategic Importance in 2026 IT risk management is the structured process of identifying , assessing , mitigating , transferring , and monitoring risks to information technology assets, processes, and data. It extends beyond cybersecurity to incl...
