A penetration test is a simulated cyberattack on an organisation’s IT infrastructure, carried out by authorised people to determine the system's security, or lack thereof. This test can take different forms, but the overarching goal is to identify weaknesses in the company’s IT security.
BlueVision ITM believes penetration testing is a vital component of cybersecurity, and notes it goes beyond vulnerability scanning. Its engineers use multi-step and multi-vector attack scenarios to find vulnerabilities and misconfigurations and then attempt to exploit them to move deeper into an enterprise’s infrastructure.
This approach is echoed by the global research house Gartner, which explains how advanced targeted attacks work. Penetration testing provides visibility into aggregations of misconfigurations or vulnerabilities that could lead to an attack that could cause serious business impact. Gartner further confirms as a minimum, penetration testing provides a means for prioritising the highest risk vulnerabilities.
“At BlueVision ITM we believe penetration testing, often also referred to as ‘pen testing’, is a critical component of modern cybersecurity endeavours,” says Christo Coetzer, Director and CEO, BlueVision ITM. “It is particularly significant for businesses aiming to identify and address vulnerabilities before attackers can exploit them. Pen testing involves ethical hackers simulating real-world attacks on a system, network, or application to uncover weaknesses in security controls. This process helps companies to stay ahead of cybercriminals by identifying and rectifying potential risks before they become actual incidents.”
He notes one of the key points to consider is the clarification of what exactly penetration testing is. “It is imperative to understand that this is a simulated cyberattack conducted by skilled professionals with the organisation's permission. It is an important exercise as it provides early identification of vulnerabilities, prevents exploitation, enhances security posture, reveals the potential impact of an attack, and ensures compliance with regulations like GDPR or ISO 27001 and more.”
“Pen testing can occur at different levels, including network, web application, mobile and even physical. Understanding what an organisation needs is paramount in tailoring the type of pen test. The exercise targets each specific area of concern. Moreover, it is crucial to break down the stages of pen testing, such as reconnaissance, scanning, exploitation, and reporting. Doing this helps to demystify the process,” adds Coetzer.
He cites common misconceptions of pen testing include the myth that pen testing is the same as vulnerability scanning – it is not. Or that it guarantees total security – it does not.
Third-party risk assessment
“Many organisations overlook the security risks posed by third-party vendors. Penetration testing should not only be conducted internally, but also to assess the security of third parties with access to your organisation’s sensitive systems or data. Ensuring that vendors adhere to rigorous security standards is crucial for preventing breaches originating from external partners,” confirms Coetzer.
He advises when working with third parties, organisations should include penetration testing clauses in their contracts to ensure vendors are regularly testing their own security. “This adds an extra layer of accountability, ensuring that weak links in the supply chain are identified and resolved before they can be exploited.”
The role of BlueVision ITM
As a professional services business specialising in offensive security, BlueVision ITM serves as an independent party that conducts penetration tests for organisations, or their external partners to ensure security standards are met and risks made visible.
“We strive to provide an introductory guide for businesses and professionals looking to understand how penetration testing fits into their overall cybersecurity strategy,” concludes Coetzer.
