1. Introduction

The New Norm

In an era where cyber threats are becoming increasingly sophisticated, securing your organization's external perimeters is no longer sufficient. The internal landscape of your network can also be vulnerable to attacks, and overlooking this aspect can be a costly mistake.

Objective of this Post

This post aims to guide organizations in understanding the ins and outs of internal penetration testing, its importance, the different types, and how it can significantly enhance their cybersecurity posture.

2. Understanding Internal Penetration Testing

What is Internal Penetration Testing?

Unlike external penetration testing, which focuses on vulnerabilities accessible from outside the organization, internal pen testing aims to identify and exploit weaknesses within the internal network.

Scope and Objective

The objective is to simulate an attack originating from within the internal network, which could be a disgruntled employee, an intruder who has bypassed the external defenses, or a malware-infected device connected to the network.

3. Why Internal Pen Testing is Crucial

Protecting Against Insider Threats

Insider threats, whether intentional or accidental, are increasingly common and can cause significant harm. Internal pen testing can help identify vulnerabilities that insiders may exploit.

Regulatory Requirements

Compliance mandates often necessitate internal pen testing to ensure that sensitive data is adequately protected from internal threats as well.

4. Types of Internal Penetration Tests

Network Penetration Tests

Focusing on the network infrastructure, these tests aim to identify vulnerabilities in routers, switches, and servers. SubRosa offers in-depth Network Penetration Testing to secure your internal networks.

Web Application Tests

These tests look for vulnerabilities in web applications that are accessible internally. Our Application Security Testing services can help you discover and patch these vulnerabilities.

Social Engineering Tests

Though not entirely technical, social engineering tests target your employees to gauge their susceptibility to phishing attacks and similar tactics. SubRosa provides specialized Social Engineering Penetration Testing to evaluate and improve your staff's awareness.

Physical Security Tests

These tests aim to identify potential vulnerabilities in physical access to critical systems and data storage. Our Physical Penetration Testing services are comprehensive in addressing these areas.

5. Steps Involved in Internal Penetration Testing

Planning

This initial step involves defining the scope, objectives, and methods to be used in the test.

Discovery

Here, testers identify the assets within the scope and gather as much information as possible about them.

Attack Simulation

In this phase, actual exploitation attempts are made, focusing on various vulnerabilities discovered during the discovery phase.

Analysis and Reporting

The final step involves compiling the test's findings into a comprehensive report that outlines vulnerabilities, data accessed, and recommendations for securing the environment.

6. Tools and Techniques

Scanning Tools

Tools like Nmap and Nessus can be extremely helpful in identifying active devices, open ports, and running services.

Exploitation Frameworks

Metasploit is commonly used for developing, testing, and executing exploit code against a remote target.

Manual Techniques

Manual testing techniques involve directly interacting with the system, often using custom scripts and tools designed for specific vulnerabilities.

7. Best Practices for Effective Internal Penetration Testing

Regular Testing

Internal pen testing should not be a one-time activity but should be conducted regularly to keep up with evolving threats.

Comprehensive Scope

Ensure that the test is comprehensive, including all potential targets like IoT devices, legacy systems, and third-party applications.

Informed Testing

Keep stakeholders informed about the test to ensure there are no misunderstandings or disruptions.
