What is Penetration Testing?  

A penetration test (pen test) is an authorized simulated attack performed on a computer system to evaluate its security. Penetration testers use the same tools, techniques, and processes as attackers to find and demonstrate the business impacts of weaknesses in a system. Penetration tests usually simulate a variety of attacks that could threaten a business. They can examine whether a system is robust enough to withstand attacks from authenticated and unauthenticated positions, as well as a range of system roles. With the right scope, a pen test can dive into any aspect of a system.

Internal Pen Test for betterSecurity

An internal penetration test  is a simulated cyberattack conducted by security professionals from within the organization’s network. Unlike external penetration tests, which assess external-facing systems, internal tests focus on identifying vulnerabilities and weaknesses from within the organization’s perimeter.

With rising cybersecurity threats, compliance requirements, and penalties for non-compliance, businesses are looking for more ways to be proactive. Your organization’s security approach may seem full proof, but how can you be sure that it will stand up to in the event of employee negligence or error?

Do I Need an Internal Penetration Test?

The short answer is: “it depends”. It is generally recommended that organizations of all sizes and industries conduct regular penetration testing to identify vulnerabilities and weaknesses in their network and systems.

If your organization stores sensitive data or is subject to compliance requirements, such as HIPAA or PCI-DSS, then conducting internal penetration testing may be necessary to meet those requirements. Additionally, if your organization has undergone significant changes in the IT environment, such as the introduction of new technologies or software, it may be beneficial to conduct an internal penetration test to ensure that the security posture has not been compromised.

Why Conduct an Internal Penetration Test?

Conducting an internal penetration test can provide several benefits for an organization, including:
1
Identifying vulnerabilities
The primary objective of an internal penetration test is to identify vulnerabilities in the network or system that could be exploited by an attacker. This information can be used to remediate vulnerabilities and improve the overall security posture of the organization.
2
Testing security controls
An internal penetration test can help evaluate the effectiveness of security controls, such as firewalls, intrusion detection systems, and access controls. This information can be used to improve security controls and ensure that they are functioning as intended.
3
Testing incident response
An internal penetration test can help evaluate an organization’s incident response procedures and identify areas for improvement. This can help ensure that the organization is prepared to respond to a real-world attack.
4
Meeting compliance requirements
Some industries, such as healthcare and financial services, have regulatory requirements for conducting penetration testing. Conducting an internal penetration test can help meet these requirements and demonstrate compliance.

LiviwirExperts' Pen testing practices and methodologies

Conducting an internal network scan involves using specialized tools to assess the security posture of devices and systems within the organization's internal network. This process helps identify vulnerabilities, misconfigurations, and potential security risks present within the network infrastructure.
Services probing entails examining the services running on network devices and servers to identify open ports, running applications, and potential security vulnerabilities. By probing services, security teams can assess the attack surface and determine if any services are exposed unnecessarily, which could be exploited by attackers.
Firewall and Access Control List (ACL) analysis involves reviewing the configuration settings of firewalls and access control lists deployed within the internal network. This analysis aims to ensure that firewall rules and ACLs are configured correctly to restrict unauthorized access and prevent malicious traffic from entering or leaving the network.
System fingerprinting is the process of identifying and gathering information about devices and systems within the internal network. This includes determining the operating system, software versions, and services running on each device. System fingerprinting helps security teams understand the network environment and identify potential security vulnerabilities associated with specific systems.
Manual vulnerability scans involve security experts manually inspecting systems and applications for vulnerabilities that may not be detected by automated scanning tools. After identifying potential vulnerabilities, security professionals verify the findings through manual testing to assess their severity and exploitability. This ensures a comprehensive assessment of security risks within the internal network.
