Network Pentesting External

Network penetration testing, or "pentesting," is a proactive security assessment method that simulates real-world attacks on your network infrastructure. This approach helps identify vulnerabilities and weaknesses before malicious actors can exploit them.

Our External Network Penetration Testing (ENPT) service is designed to conduct a thorough analysis of your publicly accessible network assets. Using a combination of proprietary automated tools and internally developed vulnerability scanning scripts, we perform comprehensive scanning to identify potential security weaknesses. Our process includes basic Open-Source Intelligence (OSINT) to map the attack surface of assets and domains on the internet, allowing us to gather passive reconnaissance data. Additionally, we employ both automated scans and manual techniques to discover vulnerabilities, such as subdomain takeover and the exposure of sensitive data on third-party websites.

Approach

Our methodology for external network penetration testing includes the following steps:

  • img

    Preparation

    • Define scope and objectives.
    • Gather information about external network infrastructure

  • img

    Reconnaissance

    • Passive: Use OSINT to gather information.
    • Active: Conduct port scanning and fingerprinting.

  • img

    Enumeration and Analysis

    • Identify open ports, services, and vulnerabilities.
    • Analyze potential attack vectors and entry points

  • img

    Exploitation

    • Attempt to exploit vulnerabilities such as unpatched software or weak authentication.
    • Gather information about external network infrastructure

  • img

    Post-exploitation

    • Establish persistence and escalate privileges.
    • Pivot to other systems if possible.

Frequently Asked Questions

img

Network Pentesting, or Network Penetration Testing, involves simulating realworld attacks on a network infrastructure to identify vulnerabilities and weaknesses, evaluating the security of both internal and external networks.

External Network Pentesting assesses the security of publicly accessible network infrastructure, like internet-facing servers and web applications. Internal Network Pentesting evaluates the security of internal network segments, including servers and workstations within the organization.

External Network Pentesting uses tools like Nmap, Nessus, and Metasploit. Internal Network Pentesting also incorporates techniques such as privilege escalation, lateral movement, and network sniffing

External networks often have vulnerabilities like misconfigured firewalls, unpatched software, and weak authentication mechanisms. Internal networks typically face issues like weak password policies, outdated software, and insufficient access controls.

Organizations should define clear objectives and scope, obtain necessary permissions, and inform stakeholders about the assessment. Network pentesting helps identify vulnerabilities, prioritize remediation, and enhance security posture, reducing the risk of cyber-attacks and data breaches.
