NETWORK ARCHITECTURE SECURITY REVIEW
Build a Network Architecture Designed to Resist Attack Paths
Network security is not only about identifying vulnerabilities in individual devices. The way networks are designed, segmented and interconnected determines how effectively an organization can contain unauthorized access and limit attacker movement.
Consultants Factory’s Network Architecture Security Review evaluates the design of the network, trust boundaries, segmentation model, connectivity paths and placement of security controls to determine whether the architecture effectively protects critical systems.
Unlike a conventional network penetration test, this service focuses on architecture and security design rather than simply identifying technical vulnerabilities.
Key Security Challenges We Address
Weak Network Segmentation
Identify architectural weaknesses that may allow inappropriate communication between security zones.
Unclear Trust Boundaries
Assess whether trust boundaries between Internet, DMZ, internal, management, cloud and other environments are clearly defined and effectively enforced.
Excessive Network Connectivity
Identify unnecessary communication paths that may increase attack-path opportunities.
Security-Control Placement Gaps
Assess whether critical security controls are positioned effectively within the architecture.
Lateral-Movement Risk
Evaluate whether the architecture adequately limits movement from lower-trust environments toward critical systems.
Our Approach
1. Architecture & Environment Understanding
We review the relevant network architecture, including:
- Logical architecture
- Physical architecture
- Network zones
- Security domains
- Critical systems
- Connectivity
- Cloud/hybrid environments
- Security controls
Objective: Establish a clear understanding of the network’s overall security architecture.
2. Trust Boundary & Segmentation Review
We evaluate:
- Internet boundaries
- DMZ
- Internal networks
- Management networks
- Guest networks
- Server networks
- Cloud networks
- OT/specialized zones where applicable
- Critical-system isolation
Objective: Determine whether important security boundaries are clearly defined and appropriately enforced.
3. Traffic Flow & Security-Control Analysis
We assess relevant:
- North-south traffic flows
- East-west traffic flows
- Inter-zone communication
- Firewall enforcement points
- Access-control mechanisms
- Network security controls
- Connectivity dependencies
Objective: Identify architectural paths that could create unnecessary security exposure.
4. Resilience & Security Architecture Assessment
Where applicable, we assess architectural considerations such as:
- Redundancy
- High availability
- Single points of failure
- Critical network paths
- Security-control resilience
- Architectural dependencies
We can also consider relevant least-privilege, segmentation and Zero Trust architecture principles where applicable to the client’s environment.
Objective: Identify architectural improvements that can strengthen security and resilience.
5. Architecture Risk Reporting
Our report can provide:
- Executive Summary
- Current-State Architecture Observations
- Trust-Boundary Analysis
- Segmentation Assessment
- Security-Control Placement
- Architectural Risk Areas
- Business Impact
- Prioritized Recommendations
- Targeted Improvement Roadmap
The underlying service definition specifically distinguishes this review from network penetration testing and focuses on architecture, trust boundaries, segmentation, traffic flows, security-control placement, critical assets, connectivity, Zero Trust and resilience.
