Internal Network Penetration Testing

An internal network penetration test focuses on identifying vulnerabilities in the infrastructure and systems that are accessible from within your organization.

What Happens During an Internal Network Pen Test?

This type of testing simulates attacks that would come from malicious actors like rogue employees, contractors, or potentially a trusted user with a compromised asset—those that already have access to your internal environment.

An Internal Network Penetration Test Can Help You:

Prepare for Real-World Attacks

Because this type of test provides a simulation of real-world attacks, it can help you identify and prepare for the potential threats lurking out there.

Improve Your Security Posture

An internal pen test provides the sum of vulnerabilities existing on your internal network, alongside remediation recommendations that will help increase your security posture.

Meet Compliance Requirements

Depending on your industry and the relevant regulations, an internal network pen test may be required for compliance purposes.

Provide A Sense Of Security

By performing regular penetration tests, you can establish confidence in your security posture and demonstrate this to customers, partners, and stakeholders.

Schellman’s Internal Network Penetration Testing Methodology

We use two different attack scenarios during an internal network penetration test:

1. Rogue Device Plugged Into Your Corporate Network: We will provide you with a Schellman-controlled device for you to plug into your network. After the initial setup, we’ll test to reveal what could an attacker do from this perspective.

2. Low-Privileged Employee: You’ll onboard our team with this access, and we’ll attempt to escalate privileges, pivot through your network, and compromise the entire domain.

In executing these two scenarios for internal network penetration testing, we use techniques like network mapping, unauthenticated internal vulnerability scanning, password cracking, open network share enumeration, Active Directory attacks, and exploitation of identified vulnerabilities. All are frequently mapped back to the MITRE ATT&CK Enterprise framework.
