What is penetration testing?

Penetration testing, often referred to as pen testing, is a proactive cybersecurity measure designed to evaluate the security of an organisation's IT infrastructure by simulating real-world cyberattacks. The goal is to identify weaknesses in the system's defences, including networks, applications, and endpoints, before they can be exploited by adversaries.

The history of penetration testing dates back to the early days of computing when hackers, known as "white hats," would test the security of systems with the owner's permission to identify vulnerabilities. Over time, pen testing evolved into a formalised process conducted by skilled cybersecurity professionals.

Why has penetration testing become more popular in recent years?

In recent years, the prevalence of cyber threats has skyrocketed, with hackers employing increasingly sophisticated techniques to breach corporate defences. As a result, businesses are under constant pressure to fortify their cybersecurity measures. Penetration testing has gained popularity as a proactive approach to identifying and addressing vulnerabilities before they can be exploited by malicious actors.

Understanding the phases of penetration testing can expedite the process of implementing necessary security changes within a company. By shedding light on the methods employed by cybercriminals, penetration testing helps businesses stay one step ahead in the ongoing battle against cyber threats.

The phases of pen testing

Penetration testing typically consists of several distinct phases, each serving a specific purpose in the assessment process. These phases include:

1. Planning phase:

The planning phase serves as the foundation of the penetration testing process, laying the groundwork for a comprehensive assessment. During this stage, cybersecurity professionals collaborate closely with stakeholders to define the scope, objectives, and methodologies of the test. This involves gaining a thorough understanding of the organisation's infrastructure, including networks, applications, and critical assets, to identify potential areas of vulnerability.

Moreover, penetration testing requirements, such as compliance standards and regulatory mandates, are carefully considered to ensure that the assessment aligns with the businesses security goals. By establishing clear objectives and scope upfront, the planning phase sets the stage for a focused and effective penetration test.

2. Scanning phase:

Once the planning phase is complete, the penetration testing team proceeds to the scanning phase, where they conduct a thorough examination of the target environment. This involves employing specialised tools and techniques to identify potential entry points and vulnerabilities within the organisation's systems and networks.

Network scanning tools, such as port scanners and vulnerability scanners, are utilised to map out the network topology and identify open ports, services, and potential security weaknesses. Similarly, web application scanners are employed to assess the security of web applications, identifying common vulnerabilities such as SQL injection, cross-site scripting (XSS), and insecure authentication mechanisms.

3. Attacking phase:

With vulnerabilities identified during the scanning phase, the penetration testing team proceeds to the attacking phase, where they attempt to exploit these weaknesses to gain unauthorised access to the target environment. This phase simulates real-world cyberattacks, allowing businesses to assess the effectiveness of their security controls in detecting and mitigating threats.

Various attack techniques and methodologies may be employed during this phase, including brute-force attacks, SQL injection, buffer overflows, and social engineering tactics. By emulating the tactics used by malicious actors, penetration testers provide organisations with valuable insights into their security defences' strengths and weaknesses.

4. Reporting phase:

Following the completion of the penetration test, the reporting phase involves documenting the findings and observations gleaned throughout the assessment. A comprehensive report is generated, detailing the vulnerabilities discovered, the potential impact they could have on the organisation, and actionable recommendations for remediation.

The penetration testing report serves as a valuable resource for stakeholders, providing them with insights into the company’s security posture and prioritising remediation efforts. Additionally, it helps organisations meet compliance requirements and regulatory mandates by demonstrating a proactive approach to cybersecurity.

Who performs a pen test?

Penetration tests are typically conducted by skilled cybersecurity professionals with expertise in identifying and exploiting security vulnerabilities. There are two main types of penetration tests:

Internal penetration tests

These tests are conducted by individuals or teams with insider knowledge of the company’s infrastructure. They simulate attacks launched from within the internal network, such as an employee's workstation, to assess the effectiveness of internal security controls.

External penetration tests

External penetration tests are conducted from outside the organisation's network, simulating attacks launched from the internet. They assess the security posture of external-facing systems, such as web servers and firewalls, to identify vulnerabilities that could be exploited by external attackers.

What are the benefits of penetration testing?

Updating security

Penetration testing helps businesses identify and remediate security vulnerabilities, strengthening their overall security posture and reducing the risk of cyberattacks.

Peace of mind

By proactively identifying and addressing security weaknesses, penetration testing provides organisations with peace of mind, knowing that they are taking proactive steps to protect their data and assets.

Showing responsibility

Conducting regular penetration tests demonstrates a commitment to cybersecurity and regulatory compliance, helping companies build trust with customers, partners, and regulators.

Saves money

By identifying and addressing security vulnerabilities before they can be exploited by attackers, penetration testing can save organisations significant financial costs associated with data breaches, downtime, and reputational damage.
