network-segmentation SKILL.md skillA
network-segmentation from hermeticormus/libresecops-claude-code is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hermeticormus/libresecops-claude-code/network-segmentation@git:20260930.71a2663Pins git:20260930.71a2663 in mdr.lock. Pin the fingerprint instead.

Network segmentation strategies: trust zones, VLAN and DMZ design, micro-segmentation, and lateral movement prevention. Use when designing segmentation or assessing how far a compromise could spread inside a network.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Network Segmentation > Segmentation strategies, trust zone design, micro-segmentation, and lateral movement prevention. ## Knowledge Base ### Why Segmentation Matters In a flat network (no segmentation), compromising any single host gives an attacker direct network access to every other host. Lateral movement is trivial -- the attacker can reach databases, admin panels, and other servers directly from the compromised host. Segmentation creates boundaries that an attacker must cross. Each boundary is an opportunity for detection and prevention. The goal is to limit the blast radius of any single compromise. ### Segmentation Models | Model | Granularity | Implementation | Use Case | |-------|-------------|----------------|----------| | **Perimeter** | Network edge only | Edge firewall | Legacy, insufficient alone | | **Zone-based** | Trust zones (DMZ, Internal, DB) | Firewalls between zones | Traditional enterprise | | **VLAN-based** | Per functional group | 802.1Q VLANs + ACLs | Network-level isolation | | **Micro-segmentation** | Per workload/application | Host firewalls, SDN, service mesh | Modern data center, cloud | …

How to install
mdr add hermeticormus/libresecops-claude-code/network-segmentation@sha256:a5837882d31cda5cThe line at the top of this page pins the label git:20260930.71a2663, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
