Dependency Management is Critical for Disaster Recovery After a Security Incident
- Dependency management is critical for businesses to recover data and restore services after a cyber attack.
- To ensure service availability and reliability, organizations require a comprehensive data and dependency catalog including relationships between each entity.
- Following a disaster recovery maturity model, businesses can progressively approach each level to reach their desired state of capability.
- In a 4-level system, understanding and managing dependencies can be somewhere between Level 2 or Level 3.
- Technical dependencies should be identified first, including direct and transitive dependencies, forming a directed acyclic graph.
- Process dependency defines how different stakeholders work together to move forward, outlining release process or runbooks to invoke during an incident.
- Continuous integration tools can enumerate and track direct code and library dependencies.

- Dependencies requiring updating or removal can be identified and resolved at Level 3.
- Manual and automated disaster recovery drills ensure businesses have robust contingency plans in place.
