External Network Penetration Testing

An external network penetration test, required for many compliance frameworks and one of the primary services when speaking about penetration testing, will identify and exploit vulnerabilities in your organization's Internet-facing infrastructure.

An External 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 understand the impact of misconfigured services or unpatched vulnerabilities on Internet-facing hosts.

Improve Your Security Posture

Identify security weaknesses and vulnerabilities in your external network infrastructure and systems—the results and our recommendations would help you prioritize the appropriate security improvements to reduce the risk of external attacks.

Demonstrating Due Diligence

Conducting regular penetration tests can demonstrate to customers, partners, and other stakeholders, that you take security seriously and are taking consistent steps to protect data.

Schellman's External Network Penetration Testing Methodology

Our objective is to identify potential weaknesses that can be exploited by attackers and provide recommendations for improving your security posture. 

Specific facets of our external penetration process include:

Port Scanning

We’ll scan your network to identify open ports and services that are exposed to the Internet. We’ll test all discovered TCP ports and the most common UDP ports on in-scope hosts.

 

Vulnerability Scanning

An unauthenticated scan is always our first step—the scanner will not be given any authentication when it searches for vulnerabilities. We may also perform subsequent scans that include the credentials discovered.

 

Manual Testing and Verification

Manual attacks are those that the penetration tester performs while looking for a specific weakness, or which require continual modifications to get the expected results. Unlike a vulnerability scan, which may run for hours before yielding results, manual attacks typically provide the penetration tester instant feedback on the success or failure of an attack.

Additionally, some test cases cannot be tested adequately by automated scanning.
