10-D Security Internal Penetration Test is a professional security assessment service that evaluates the effectiveness of internal security controls against attackers with access to internal network resources. The service simulates real-world attack scenarios including malicious insiders, external attackers who have gained limited access, or compromised internal systems. The assessment is conducted by trained security professionals using current attack methodologies and tactics. The testing process consists of two distinct phases: one performed with network access only, and a second phase with network access and limited user credentials to simulate an internal user compromise. The service employs Red Team techniques to detect and evaluate security controls using cutting-edge strategies similar to those used by cybercriminals. Clients define specific goals or "flags" prior to the assessment, which serve as objectives for the Red Team. These objectives typically include gaining root or administrative access to targeted systems or accessing data stores. All internal systems may be targeted during the assessment unless specifically excluded by the client. The deliverables include a detailed narrative report documenting specific attack paths and scenarios, along with recommended remediation strategies. This service is designed to complement traditional Internal Vulnerability Assessments and External Penetration Tests by evaluating how layered security controls withstand skilled attacks. The service is offered to financial institutions, healthcare organizations, and legal/professional firms requiring specialized security testing.
