Internal Network
Penetration Testing

Security Simplified conducts internal infrastructure penetration testing from an “unauthenticated internal” user perspective. The primary purpose of the assessment is to uncover network-layer vulnerabilities and misconfigurations that could result in the complete compromise of the organization’s internal network.

Security Simplified approach is targeted to gain the highest level of access within the target network i.e. domain or enterprise administrator. We perform the assessment with zero knowledge and with no user credentials (as real attackers would have). Each attack footpath exploitation and vulnerability chaining techniques are utilized and demonstrated to gain the highest privileged access.

Our methodology and test cases are derived from the below standards:

  • Penetration Testing Execution Standard (PTES)
  • MITRE ATT&CK Framework
  • Open Source Security Testing Methodology Manual (OSSTMM)
