Upon completion of this course, participants will be able to:

• Configure and manage **SCADA Server Redundancy** and automatic failover procedures.
• Develop and implement a comprehensive **data backup and disaster recovery plan** for the SCADA environment.
• Master the procedures for applying system patches and updates safely in an **OT (Operational Technology)** environment.
• Manage user accounts, privileges, and access control lists (ACLs) across the system.
• Monitor key SCADA server performance metrics (e.g., CPU, memory, I/O rates) for proactive maintenance.
• Manage software licensing, version control, and configuration documentation.
• Perform routine preventive maintenance and system diagnostics to ensure high availability.

• SCADA System Administrators and IT/OT Support Staff
• Control System Engineers responsible for system uptime
• Maintenance and Reliability Managers
• Disaster Recovery and Business Continuity Planners
• Project Managers overseeing SCADA upgrades and infrastructure

• Hands-on lab exercises configuring and testing server redundancy and automatic failover in a simulated environment.
• Group activity: developing a prioritized **Disaster Recovery Plan** for a high-consequence SCADA system.
• Individual exercises in documenting a safe patch management procedure for a control system server.
• Case studies of major outages caused by lack of redundancy or failed recovery attempts.
• Discussions on balancing system security requirements with operational maintenance needs.

Unit 1: SCADA Server Management

• Review of the core SCADA server roles: Historian, I/O Server, Application Server
• Best practices for operating system configuration and hardening for OT environments
• Managing software services and dependencies for optimal performance

• Implementing a robust user management framework (e.g., role-based access control, LDAP integration)
• Auditing user activity and managing security event logs

Unit 2: High Availability and Redundancy

• Understanding the need for **SCADA Server Redundancy** (Hot Standby, Cold Standby)
• Configuring automatic synchronization and state replication between primary and secondary servers

• Developing and executing controlled **failover testing** procedures to ensure functionality
• Configuring network and communication redundancy for critical data links

Unit 3: Maintenance, Patching, and Lifecycle

• Developing a safe and systematic process for applying OS and SCADA software patches in OT
• The importance of vendor approvals and testing before applying any updates

• Managing software licensing and compliance for all SCADA components
• Developing a system lifecycle roadmap for hardware and software obsolescence planning

Unit 4: Backup and Disaster Recovery

• Identifying all critical system files for backup (configuration, code, database archives)
• Implementing an automated, verified, and geographically diverse backup schedule

• Developing a detailed **Disaster Recovery (DR) Plan** with documented recovery time objectives (RTO)
• Practicing system restoration from backup in a test environment

Unit 5: Performance Monitoring and Auditing

• Using system tools to track key server health metrics (memory usage, I/O bandwidth, disk latency)
• Implementing proactive alerts for server performance degradation

• Procedures for auditing system configurations against documentation standards
• Maintaining meticulous records of all system changes, updates, and maintenance activities
