INTERNAL NETWORK SECURITY ASSESSMENT
Identify Internal Security Weaknesses Before Attackers Move Deeper
An attacker does not necessarily need to compromise an organization directly from the Internet. A compromised endpoint, stolen credential or malicious insider can provide an initial foothold inside the network.
Once inside, weaknesses in segmentation, authentication, internal services and access controls may allow an attacker to move toward higher-value systems.
Consultants Factory’s Internal Network Security Assessment evaluates the internal network from the perspective of an attacker who has obtained authorized network access and is attempting to identify additional systems, services and potential lateral-movement paths.
The service focuses on Internal Systems, Services, Network Segmentation, Privilege Escalation and Lateral Movement.
Key Security Challenges We Address
Weak Internal Segmentation
Identify weaknesses that may allow communication between systems or security zones that should be isolated.
Excessive Internal Access
Identify unnecessarily broad access to internal systems and services.
Lateral-Movement Opportunities
Assess whether an attacker with an initial foothold could potentially move toward additional systems.
Vulnerable Internal Services
Identify security weaknesses across approved internal services, servers and infrastructure.
Privilege Escalation Paths
Assess authorized attack paths that could potentially enable escalation toward higher-privileged access.
What we access
- Servers
- Internal systems
- Network devices
- Internal services
- Network segmentation
- Trust boundaries
- Management interfaces
- Access controls
- Privilege escalation
- Lateral movement
- Internal attack paths
The underlying client-scoping material also specifically covers internal IP/CIDR ranges, hosts, services, segmentation and authorized testing conditions.
Our Approach
1. Internal Asset Discovery
We begin by identifying approved internal network assets and services.
This may include:
- Internal IP ranges
- Subnets
- Hosts
- Servers
- Network devices
- Internal services
- Management interfaces
- Authentication infrastructure
Objective: Establish visibility into the internal attack surface.
2. Internal Vulnerability & Service Assessment
We assess identified systems and services for security weaknesses.
Depending on scope, this may include:
- Service enumeration
- Vulnerability identification
- Configuration assessment
- Authentication exposure
- Internal service security
- Management interfaces
- Network-device exposure
Objective: Identify weaknesses that could contribute to internal compromise.
3. Segmentation & Access-Control Validation
We assess whether security boundaries are effectively enforced between internal environments.
Testing may consider:
- VLANs
- Subnets
- Security zones
- Firewall boundaries
- ACLs
- Management networks
- Server networks
- User networks
- Sensitive environments
Objective: Determine whether internal security boundaries effectively restrict unauthorized access.
4. Lateral-Movement & Privilege-Path Analysis
Where explicitly authorized, we analyze potential paths from an initial foothold toward additional systems or higher-privileged resources.
This may include:
- Credential-access paths
- Privilege escalation
- Trust relationships
- Service relationships
- Administrative interfaces
- Lateral movement
- Sensitive network segments
Objective: Identify attack paths that could increase the impact of an internal compromise.
5. Reporting & Remediation
Findings are documented with:
- Affected assets
- Technical evidence
- Risk classification
- Potential attack path
- Security impact
- Business impact
- Remediation recommendations
- Risk prioritization
Objective: Help organizations strengthen internal security controls and reduce lateral-movement risk.
