Information Systems Operations and Business Resilience - IS Operations

Information Systems (IS) Operations within the context of CISA refers to the day-to-day management and maintenance of an organization's information technology infrastructure. It encompasses the processes, procedures, and controls that ensure the reliable functioning of information systems. IS Operations includes several key components: 1. Infrastructure Management: Overseeing servers, networks, databases, and applications to ensure optimal performance and availability. 2. Change Management: Controlling modifications to the IT environment through formal processes to minimize disruption and risk. 3. Problem Management: Identifying, analyzing, and resolving incidents and issues within the IT environment. 4. Capacity Planning: Ensuring adequate resources are available to meet current and future business needs. 5. Performance Monitoring: Continuously tracking system metrics to identify bottlenecks or areas for improvement. 6. Security Operations: Implementing and maintaining security controls to protect systems and data. 7. Job Scheduling: Managing automated tasks and batch processes to optimize resource utilization. Business Resilience in IS Operations focuses on maintaining critical functions during disruptions. Key elements include: 1. Business Continuity Planning: Developing strategies to restore operations after interruptions. 2. Disaster Recovery: Creating detailed technical procedures for recovering IT systems following disasters. 3. High Availability Solutions: Implementing redundant systems to minimize downtime. 4. Backup and Recovery: Establishing procedures for data protection and restoration. Effective IS Operations requires clear policies, documented procedures, qualified personnel, and appropriate monitoring tools. Auditors assess these areas to ensure: - Operations align with business requirements - Proper segregation of duties exists - Adequate environmental controls protect physical infrastructure - Incident response procedures are effective - System monitoring is comprehensive - Recovery capabilities meet business requirements IS auditors evaluate these aspects to verify that operations support business objectives while maintaining appropriate controls and resilience capabilities.
