For each service you identify in section 3.4, think about what you can do in advance to prepare the firm for the loss of those services. Consider both response and recovery requirements.
Some examples:
- Implement redundant power supplies and network connections to reduce the risk of service interruptions
- Design, implement and test backup systems to ensure that critical data can be quickly and reliably restored
- Use immutable or offline backups to prevent encryption/deletion by attackers
- Maintain up-to-date inventories of hardware, software, and key contacts to streamline recovery efforts
- Pre-arrange alternate work locations or remote access solutions for employees in the event primary facilities are inaccessible
- Establish and document clear communication plans so staff know who to contact and what steps to take during a disruption
- Ensure that all critical service providers and vendors have their own robust disaster recovery plans in place
- Train team members through periodic simulations to ensure familiarity with business continuity and disaster recovery procedures
- Review and update insurance coverage to address potential risks associated with various disaster scenarios
