Study Notes
IT Systems and Business Continuity
- This study unit covers 15% to 25% of Part 3 of the CIA exam.
- It's tested at an awareness level.
- The syllabus section covers Security, Application Development, System Infrastructure, Functional areas of IT operations, ERP, data communications, software licensing, mainframe, operating systems, web infrastructure and business continuity.
Functional Areas of IT Operations
- Segregation of duties is important in IT operations.
- Clear separation of roles like systems analyst, programmer, operator, file librarian, and others, with supervision.
- Mainframes had specialized roles in the past, but roles have become blurred with decentralization.
- Maintaining proper segregation is vital, even in modern IT environments due to the blurring and disappearance of many traditional job roles.
- This is a critical control, as it helps prevent fraud, error, and inefficient operations.
Enterprise-Wide Resource Planning (ERP)
- ERP is a current system for managing organization resources, integrating enterprise-wide systems across the organization.
- It connects various functional subsystems (human resources, finance, production, marketing, distribution, purchasing, etc.) and links the organization to suppliers and customers.
- ERP improves demand analysis, just-in-time inventory management, and flexible responses to supply and demand changes.
- ERP systems are complex and costly, mostly used by the largest enterprises; however, mid-size organizations are increasingly buying them to implement best practices.
- ERP often necessitates re-engineering of business processes to realize its benefits and ensure standards and practices align with the software itself.
Web Infrastructure
- The Internet is a global network of interconnected networks, originally developed by ARPA in 1969.
- The Internet facilitates inexpensive communication and information transfer among computers.
- Most Internet access points go through Internet Service Providers (ISPs).
- Internet topology resembles a complex network rather than a simple spine-like structure.
- Internet communications use servers, clients, and the TCP/IP protocol suite.
IT System Communications
- Systems software manages computer resources.
- Operating systems are the fundamental system software, acting as the interface between users, applications, and computer hardware.
- Utilities perform basic data maintenance tasks (sorting, merging, copying, deleting).
- Networks consist of hardware devices and communication mediums.
- Client devices (e.g., computers, phones) connect to networks using network interface cards (NICs).
- Protocols govern communication between devices in a network.
- Local Area Networks (LANs) connect devices within a single location.
- Client-server arrangements in LANs, where devices (clients) request services from a central server, is more efficient than the peer-to-peer arrangement.
- Wide Area Networks(WANs) connect devices across multiple locations.
- Packet Switching and Circuit Switching are communication protocols to facilitate data transfer.
- Different networking protocols exist for diverse functions like VoIP (voice communications over the internet).
Contingency Planning
- Contingency planning is critical to resuming operations after disruptions.
- Disaster recovery is the process to restore operations in the event of major disruptions (e.g., power failure or natural disaster).
- Business continuity involves the continuation of operations using alternate methods during disruptions.
- Contingency plans should include procedures, vendors, and systems considerations for disaster recovery.
- Backup files and offsite data rotation are critical to recover data in case of data center disruption or natural disaster.
- Recovery center types include hot sites (fully operational, immediately available), warm sites (partially operational), and cold sites (minimal equipment).
