What is Internal Penetration Testing?

Network testing is a way to find and fix problems in your computer network. It looks for weaknesses that bad people might use to break in and cause trouble. This kind of testing copies what bad people might do, like if someone who works for you gets mad and wants to do bad things. It’s a good idea to do network testing once a year or after you make big changes to your network. This helps you keep up with the latest tricks and ways to break into networks. Some rules say you have to do network testing, like PCI-DSS, ISO27001, and SOC 2.

Why Conduct an Internal Pentest?

Conducting an internal penetration test provides invaluable insights into the potential security risks your organization may face from internal threats. Here is what you will gain after conducting a project with our team:

Our external penetration tests will help validate the effectiveness of your existing security controls in preventing and detecting external attacks. By simulating an attacker, our experts will identify gaps in your defenses and provide remediation measures to improve your ability to prevent cyberattacks.

Our internal penetration testing service will simulate real-world attack scenarios to help you understand the consequences of a successful breach. This includes the potential for data loss, system downtime, and reputational damage. By knowing the potential impact, you can prioritize remediation efforts and better protect your organization.

Using a mix of automated and manual techniques, our team will identify all security vulnerabilities within your internal network, including misconfigurations, outdated software, and weak access controls. This will help you prioritize remediation efforts and reduce your overall risk exposure.

Our services will provide detailed information on how an attacker can breach your network from the public internet, what data or systems they could target and how to protect them. With this information, our team will provide you with prioritized recommendations to improve your security posture and protect against potential external threats.

Many regulatory frameworks require internal penetration testing to be performed as part of their compliance requirements. Our tests will help ensure that your organization meets these requirements efficiently and avoids potential penalties for non-compliance.

When Should You Perform an Internal Penetration Test?

Knowing when to conduct internal penetration testing is essential for maintaining a strong security posture. It is highly recommended to perform internal pentests in the following situations to stay proactively prepared to handle potential threats:

Common Cybersecurity Risks &
Vulnerabilities Identified

Internal penetration testing often reveals several common vulnerabilities, including:

Inadequate encryption can leave data transmissions susceptible to interception and unauthorized access.

Failing to apply security patches can leave your systems vulnerable to known exploits and attacks.

A lack of proper monitoring and logging can make it difficult to detect and respond to potential security incidents in a timely manner.

Weak or improperly implemented authentication mechanisms can allow unauthorized access to sensitive data and systems. 

Without proper data segmentation, an attacker could potentially access multiple parts of your network, leading to increased damage.

Attackers can use stolen credentials or infected devices to infiltrate your network and access sensitive information.

The Main Benefits of Testing The Security of Your Internal Network

By mimicking the actions of real-world attackers, pen testers can identify weaknesses in an organization’s internal security and help them to improve the security of critical assets. In addition to finding and fixing vulnerabilities, internal pen testing can also help organizations understand their cybersecurity risks, assess the effectiveness of their current defenses, and make more informed decisions about where to allocate their resources.

Frequently Asked Questions

Couldn’t find the information you were looking for? Ask an expert directly.

What is the purpose of an internal network penetration test?

The purpose is to assess the vulnerability of your internal network infrastructure to insider threats, such as employees, contractors, or partners. The test helps identify weaknesses, potential entry points, and the impact of a successful attack on your organization’s confidential information.

How is it performed? What is the process?

The process includes internal network scanning, port scanning, system fingerprinting, vulnerability identification, exploitation, manual vulnerability testing and verification, firewall and ACL testing, privilege escalation testing, password strength testing, network equipment security controls testing, and third-party/vendor security configuration testing.

What are the requirements to get started?

Before engaging with a provider, prepare a checklist that includes your goals for the test, the number of internal workstations, servers, and internal and external IPs on your network that you wish to assess.

Can your internal penetration tests cause downtimes?

Our internal penetration tests are designed to minimize any potential impact on your network. The overwhelming majority of our clients never notice that any testing is being done. With that said, we take all necessary measures to prevent downtimes and work closely with your team to identify any areas that may be susceptible to causing disruption to your operations.

Do we need to provide any access or permissions for the test to be conducted?

For an internal penetration test, the tester may require some level of authorized access to your network, such as user credentials or VPN access. This allows the tester to simulate an insider attack and identify vulnerabilities that may not be visible from an external perspective. The scope of access will be defined during the planning phase. In the event that on-site access is required, our team has built an internal pentesting device that can be shipped and deployed instead of requiring a tester in your facilities.

How does internal penetration testing fit into our overall cybersecurity strategy?

Internal penetration testing is a critical component of a comprehensive and mature cybersecurity strategy. It complements other security measures, such as external penetration testing, vulnerability assessments, and security awareness training, by identifying vulnerabilities within your internal network that may be exploited by an insider. Regular internal penetration tests can help you stay ahead of emerging threats, evaluate the effectiveness of your security controls, and demonstrate your commitment to maintaining a strong security posture to clients, partners, and regulators.

Will this test allow us to meet compliance requirements?

Our internal penetration tests helps several organizations of all types meet compliance requirements every year by identifying vulnerabilities that need remediation. Once remediation testing is completed, we provide an official attestation confirming that vulnerabilities have been remediated, helping organizations meet compliance requirements efficiently.

What is the difference between internal and external testing?

Internal pentesting is conducted from within the organization’s network by a tester who has access to the internal network. External pentesting is conducted from outside the organization’s network and simulates an attack on public-facing systems. The primary difference is the point of origin of the test, with internal testing being more focused on internal network security measures while external testing focuses on identifying vulnerabilities in systems that are accessible from the internet.
