# The SHIP Framework™: Industrial Network Design Methodology

*2025-08-19 · network design, framework*

*"Building networks that actually serve the people who depend on them"*

---

## **S** - **Standardize**
**"One Protocol to Rule Them All"**

- **Converge on EtherNet/IP:** Eliminate protocol chaos with standardized industrial Ethernet
- **Adopt CPwE Architecture:** Follow proven Converged Plantwide Ethernet design patterns
- **Implement TSN Standards:** Prepare for deterministic networking with IEEE 802.1 standards
- **Standardize Documentation:** Every device, every VLAN, every cable - documented and current

> *"If you can't explain your network on one page, it's too complex"*

**Practical Implementation:**
- Standardize naming conventions across all devices
- Create configuration templates for common equipment types
- Establish documentation standards that people actually follow
- Migrate from protocol chaos to EtherNet/IP where possible

**Maturity Levels:**
- **Level 1:** Multiple protocols, vendor lock-in, no standards
- **Level 2:** Moving toward EtherNet/IP, some standardization
- **Level 3:** Standardized on EtherNet/IP with CPwE principles
- **Level 4:** TSN-ready with comprehensive standards documentation

---

## **H** - **Harden**
**"Build Networks That Don't Break at 2 AM"**

- **Resilient Topologies:** Ring and redundant star configurations over daisy chains
- **Managed Industrial Switches:** Spanning Tree, QoS, and IGMP snooping as standard
- **Environmental Protection:** MICE-rated components for harsh industrial environments
- **Redundant Power:** UPS systems sized for graceful shutdowns, not indefinite runtime

> *"Your network should survive a forklift, not just a reboot"*

**Practical Implementation:**
- Replace unmanaged switches with industrial managed switches
- Implement ring topologies (DLR/REP) for critical areas
- Deploy redundant power and environmental monitoring
- Use proper grounding, shielding, and conformal coating

**Maturity Levels:**
- **Level 1:** Daisy-chain topology, unmanaged switches
- **Level 2:** Some managed switches, basic redundancy
- **Level 3:** Ring topology with DLR/REP, industrial-grade equipment
- **Level 4:** Redundant everything, environmental monitoring, predictive maintenance

---

## **I** - **Isolate**
**"Build Walls Where They Matter"**

- **Network Segmentation:** VLANs to separate functional areas and criticality levels
- **Industrial DMZ (IDMZ):** Secure buffer zone between OT and IT networks
- **Cell-Level Independence:** Each production cell operates autonomously
- **Controlled Inter-Cell Communication:** Designed communication between isolated systems

> *"If one device getting compromised takes down your entire plant, you failed at isolation"*

**Practical Implementation:**
- Create functional zones (production, safety, maintenance)
- Implement proper VLAN structures with trunk ports
- Design separate control networks for each production cell
- Prevent broadcast propagation between isolated areas

**Maturity Levels:**
- **Level 1:** Flat network, no segmentation
- **Level 2:** Basic VLAN segmentation
- **Level 3:** IDMZ implemented, functional area separation
- **Level 4:** Micro-segmentation with automated enforcement

---

## **P** - **Protect**
**"Security That Actually Works in Manufacturing"**

- **Zero Trust OT:** Authenticate every device, encrypt every conversation
- **Continuous Monitoring:** Real-time visibility into every network conversation
- **Incident Response:** OT-specific playbooks that don't assume you can "just patch it"
- **Physical Security:** Lock your network cabinets like you lock your control rooms

> *"Security that breaks operations isn't security - it's sabotage"*

**Practical Implementation:**
- Access control lists (ACLs) and port security
- Physical security considerations for network equipment
- Maintain cell-level operational autonomy even with security measures
- Deploy endpoint protection that doesn't interfere with operations

**Maturity Levels:**
- **Level 1:** "Air gap" security (hope and prayers)
- **Level 2:** Basic firewall, antivirus on HMIs
- **Level 3:** Comprehensive monitoring, incident response plan
- **Level 4:** Zero trust implementation, continuous security validation

## **Common SHIP Implementation Mistakes**

### **What Doesn't Work:**
- **Starting with Protect** - Security without foundation fails
- **Over-engineering** - Perfect is the enemy of functional
- **Ignoring operations** - Solutions that break workflows get bypassed
- **All-or-nothing approach** - Gradual improvement beats grand plans

### **What Does Work:**
- **Start with Standardize** - Foundation enables everything else
- **Build credibility first** - Quick wins enable bigger projects
- **Include operations from day one** - They have to live with your decisions
- **Iterate and improve** - Good enough that gets implemented beats perfect that doesn't

## **Integration with Other Methods**

**SHIP + STREAM Troubleshooting:**
- Well-designed SHIP networks are easier to troubleshoot systematically
- STREAM methodology works better with standardized, documented networks

**SHIP + SECURE Framework:**
- SHIP provides the foundation for implementing SECURE methodologies
- Both frameworks prioritize operational continuity over theoretical perfection

**SHIP + RIVER Method:**
- Properly hardened networks reduce the frequency of RIVER troubleshooting
- Standardized networks make RIVER troubleshooting more predictable
