- Evaluate the likelihood and potential impact of these risks.
- Infrastructure & Architecture:
- Review the design, configuration, and management of servers, networks, and telecom equipment.
- Evaluate redundancy, failover capabilities, and disaster recovery provisions.
- Data Security & Privacy:
- Assess controls around data storage, transmission, and processing.
- Ensure compliance with regulations like GDPR, CCPA, and HIPAA.
- Access Controls:
- Evaluate procedures and systems that restrict access to authorized individuals.
- Review user roles, permissions, and authentication mechanisms.
- Change Management:
- Review processes for making changes to IT and telecom systems.
- Ensure there’s a structured approach that involves authorization, testing, and documentation.
- Operational Processes:
- Examine procedures related to system monitoring, maintenance, backups, and updates.
