Overview

This lecture explains Information Technology General Controls (ITGCs), provides examples, and reviews foundational compliance frameworks that support ITGCs within organizations.

What are IT General Controls (ITGCs)?

  • ITGCs govern how technology is managed and used in an organization to prevent breaches and disruptions.
  • ITGCs cover areas like user account creation, password management, software setup, and system updates.
  • ITGCs apply to all systems, while application controls limit actions within specific platforms.

Categories of ITGCs

  • General IT Administration: Includes IT system management, oversight, risk assessments, and project best practices.
  • Access Controls: Focus on preventing unauthorized access using strong passwords, least privilege policies, and full disk encryption.
  • System Lifecycle Controls: Manage software/application/network updates and patch management to reduce risk from outdated programs.
  • Physical & Environmental Security: Involves security measures such as key badge entry and intrusion detection to protect data physically.
  • Data Protection & Recovery: Covers backup, database segregation, and business continuity plans to minimize data loss.

ITGC Compliance Frameworks

  • COSO Framework: Integrates controls into business processes for ethical and transparent operations; emphasizes environment, activities, communication, monitoring, and risk management.
  • COBIT Framework: Outlines ITGC objectives and principles like stakeholder needs, holistic approach, and separating governance from management.
  • ISO 27001 Framework: Focuses on information security and change management using a six-step, top-down compliance approach.
