What Is Internal Penetration Testing? A Complete Guide

A recent study found that more than 45% of US businesses had a data breach. Hackers will go after any company, large or small, to take advantage of a company’s cybersecurity weaknesses.

Security testing comes in many forms, but most include an external penetration test and some form of top-down risk assessment. Most industries ignored IPT, but it’s an essential part of a complete security testing strategy.

What is Internal Penetration Testing?

Internal penetration testing is a sort of software security review that acts on how an attacker will get access to a firm’s inner network. The purpose is to find points of vulnerability that an attacker could use and to test the effects of the attack.

Organizations conduct internal penetration tests, with the help of a third-party security firm. It can conduct internal penetration testing using automated tools or by exploiting vulnerabilities.

When performing an internal penetration test, you need to consider the potential impact of a successful attack. For example, an attacker who gains access to an association’s internal network may overhear sensitive data.

The output of the IPT will be the pentest report detailing the findings and advice for any vital security updates or changes. The report is designed to help the corps make informed decisions about its security posture and future security plans.

Benefits of Internal Penetration Testing

When it comes to cybersecurity, it’s important to have many layers of protection in place. Internal penetration testing is one layer that can help give you peace of mind that your systems are secure. Here are some of the benefits:

Helps Identify Vulnerabilities

Helps organizations identify vulnerabilities within their networks and systems. It evaluates a system’s security both from the view of an external malicious attacker and from within an organization itself.

Helps Assess the Security of Your System

It’s a detailed assessment of the security of a system. It is an assessment of how an attacker would respond to a system and what measures it would take to prevent or reduce the chances of a successful attack.

Types of Internal Penetration Tests

Several types of internal penetration tests can be conducted, depending on the corps’ needs. Here are some of the most common:

Black Box Testing

As the name suggests, it conducted black box testing without any prior knowledge of the system being tested. This type of test is often used to simulate a real-world attack, as it more closely resembles the way an outsider would approach the system.

White Box Testing

They conducted white box testing with full knowledge of the system’s inner workings. This type of test is often used to identify specific vulnerabilities or areas that need improvement.

Gray Box Testing

Gray box testing falls somewhere between black box and white box testing. With this type of test, the tester has some knowledge of the system being tested, but not all details are known. This approach can be useful when trying to identify both general and specific vulnerabilities.

The Process of Internal Penetration Testing

The process starts with an initial assessment of your network to determine what type of security measures are in place to protect it. Once a risk assessment is complete, the IPT specialist applies various techniques. It also uses manual techniques such as port scanning and social engineering to gain access to sensitive systems.

The entire goal of Pentest is to identify potential security gaps and threats. It then reported any weak areas found, along with recommendations on how to mitigate them. Corps need to have an extensive IPT program in place, ensuring their networks remain safe and their data is secured.

Common Techniques Used in Internal Penetration Testing

Internal penetration testing is testing the security of an internal network or system. The purpose of pen test is to identify vulnerabilities that an attacker has already gained access to the firm. It can conduct internal infrastructure penetration tests with a variety of techniques, including:


Footprinting involves gathering data about the target network, such as IP addresses, and domain names. It can gather this information through automated tools.


Scanning involves using tools to scan the target for open ports and vulnerabilities. This can provide attackers with a way to gain access to the system.


Enumeration involves trying to list all user accounts, computers, and resources on the target network or system. An attacker to gain access to sensitive data or systems can use this information.

Social Engineering

Social engineering involves using deception and manipulation techniques. This is to trick users into revealing sensitive information or providing access to systems.

Password Cracking

Password cracking involves using brute force or dictionary attacks to crack passwords used on the target system. Once passwords are cracked, attackers can gain access to sensitive data or systems.

What Are the Pros and Cons?

The pros of performing IPT are that it can help identify possible weak points that would be difficult to detect. It also ensures that the corps is not missing out on any technical areas where a potential attack may occur. Additionally, it can help reduce the risk of data theft and prevent businesses from suffering heavy financial losses.

The cons of internal penetration testing include the cost of installing more security systems. The extra time it may take to detect weaknesses in the system, and the potential for a malicious insider who is actively targeting the system. Organizations must weigh these risks before undergoing IPT.

Internal Penetration Testing You Need to Know

Internal penetration testing is an important part of the security process. It can help see vulnerabilities and give crops a better understanding of their networks to create more secure systems.

Corps may be certain that their network base is secure by running regular IPT. To guard against malicious actors who could try to take advantage of any holes or weaknesses in it. Staying one step ahead of any potential cyber-attacks by putting the proper tools and policies in place.
