Cybersecurity Architecture: Applying Identify, Protect, Detect, Respond and Recover
· 14:34 · Watch on YouTube ↗
Summary
The tutorial applies the NIST Cybersecurity Framework’s five phases to IT architecture, covering asset inventory, access controls, monitoring, incident response and tested backups.
Key points
- Inventory databases, sensitive information, servers and user devices to identify which assets need protection.
- Protect assets with authentication, authorization and access controls; layered safeguards provide defense in depth.
- Centralize system logs for security monitoring, and use endpoint detection to identify threats such as malicious attachments.
- Prepare response procedures to block threats or access, reset credentials and add authentication challenges when needed.
- Back up critical systems and test restoration so services can be recovered after a security event.
