Dmz Proposal

Secure DMZ Hosting

Example of Preliminary On-Premises Architecture Proposal

Audience: Executives, managers, non-technical stakeholders
Goal: Explain value, risk control, cost, and security in clear language.

1. Executive Summary

We propose hosting the system on physical servers within the company’s infrastructure using a secure DMZ (Demilitarized Zone) architecture. This ensures data sovereignty, security control, and independence from external cloud providers.

2. Why On-Premises?

Explain in business terms:

Full control of data
No dependency on third-party cloud providers
Compliance with internal policies
Long-term cost predictability
Increased trust for sensitive inspection data

3. What is a DMZ

Simple Non-technical explanation:

A DMZ is a secure buffer zone between the Internet and the internal company network. It ensures that even if an external attack occurs, internal systems remain protected.

Include a very simple visual diagram.

4. Proposed Architecture Overview

Explain layers in plain language:

Public access server (in DMZ)
Application processing server (internal)
Secure database server (isolated)
Controlled communication between layers

No technical ports. No jargon.

5. Security Benefits

Network isolation
Limited exposure to the Internet
Strict firewall rules
Controlled internal access
Regular backups
Audit capability

Translate everything into risk reduction language.

6. Risks & Mitigation

7. Cost Considerations

Explain clearly:

Initial hardware investment
Maintenance effort
Electricity / cooling
IT administration
No recurring cloud subscription fees

8. Roadmap (High Level)

Phase 1: Infrastructure setup
Phase 2: Application deployment
Phase 3: Security hardening
Phase 4: Go-live
Phase 5: Monitoring & optimization

9. Decision Points Needed from Stakeholders

This is critical.

Examples:

Approval for hardware budget
Approval for network configuration
Security policy alignment
Disaster recovery expectations
