Internal Network Penetration Test

Service Overview

Sec-1's Internal Network Penetration Test will share the same methodology and approach with the External Network Penetration Test. The service is designed to critically assess the Internal Network surface against security best practice.

The Internal Network Penetration Test will typically test from the perspective of both an authenticated and non authenticated user to ensure that the network is critically assessed for both the potential exploit of a rogue internal user, and an unauthorised attack.

Sec-1 uses a blend of methodologies taken from industry best practice standards such as the Open Source Security Testing Methodology Manual (OSSTMM), the Open Web Application Security Project (OWASP) and the Council of Registered Ethical Security Testers (CREST).

Service Outcomes

The service provides the client with a report that is comprehensive, clear and concise. The report is designed to provide information for a diverse audience of readers. The report delivers;

Executive Summary - The opening section of the report provides, in plain English a executive summary overview of the entire assessment including recommendations to improve the security posture of the in scope environment.

Graphical Summary - Key findings are ranked, split into three impact categories and positioned in a graphical table according to the relative risk or likelihood of exploit.

Security Evaluation by Category - The evaluation ratings compare information gathered during the course of the engagement to "best in class" criteria for security standards. An evaluation of "Excellent", "Satisfactory", "Fair" or "Improvement Required" is provided. Each category includes a best practice statement, evaluation result and recommendation to achieve best practice.

Vulnerability Analysis - The vulnerability analysis section provides a detailed description of each discovered flaw including any necessary technical information and corrective recommendations.

Exploitation Vulnerability - Each listed vulnerability is assigned a "Probability" rating based upon how likely the vulnerability is to be exploited.
