What BlidarIT Did
1
Clarify application access paths
Mapped source, destination, ports, dependencies, and business purpose.
2
Design segmentation boundaries
Translated requirements into zones, firewall policy, routing, and implementation notes.
3
Plan the change
Defined sequence, validation, rollback, and stakeholder communication.
4
Handover operations
Captured the design and rules so support could operate the environment after delivery.
Delivered Artifacts
- Access path register
- Segmentation design
- Firewall rule requirements
- Implementation plan
- Validation and rollback notes
If firewall rules exist without business purpose, segmentation work should start with dependency mapping.
