Offensive Security
Network Penetration Testing
External and internal network testing guided by PTES and NIST SP 800-115 to find and safely exploit weak services, poor segmentation, and paths to sensitive systems, under written authorization.
Overview
Network penetration testing evaluates the security of your network infrastructure from the perspective of an external attacker and a malicious insider. It answers whether exposed services, weak credentials, or flat internal networks would let an attacker gain a foothold and reach critical systems.
The approach follows the Penetration Testing Execution Standard (PTES) and NIST SP 800-115. Scope can include internet-facing hosts, internal network segments, network devices, and segmentation controls, with testing tuned to avoid disruption to production services.
Benefits
- Identifies exposed services, weak credentials, and missing patches that give an attacker an initial foothold.
- Tests internal segmentation and lateral movement to show how far an intrusion could spread.
- Follows PTES and NIST SP 800-115 for consistent, defensible methodology and coverage.
- Prioritizes findings by business impact so remediation effort targets the most serious exposure first.
Methodology
- 01
Scoping and Authorization
Agree in-scope ranges, testing windows, rules of engagement, and written authorization, including handling of any fragile production systems.
- 02
Discovery and Enumeration
Map live hosts, services, and network devices following PTES to build an accurate picture of the attack surface.
- 03
Vulnerability Analysis
Assess services and configurations against known weaknesses using NIST SP 800-115 techniques and manual validation.
- 04
Exploitation
Safely exploit confirmed weaknesses to demonstrate impact, such as credential access or unauthorized service access.
- 05
Lateral Movement and Segmentation Testing
Attempt privilege escalation and movement across segments to test internal controls and containment.
- 06
Reporting and Retesting
Deliver prioritized findings with remediation guidance and confirm fixes through retesting.
