What is penetration testing?  

Penetration testing is a simulated cyber attack against a computer system or network to identify exploitable vulnerabilities. It involves authorised individuals attempting to compromise systems and data using the same techniques that malicious hackers might employ.  

Penetration testing helps you assess your organisation’s security posture, identify weaknesses and take corrective actions to mitigate potential risks. It can be conducted in various forms, such as black box testing where the tester has no prior knowledge of the target system to white box testing where the tester has full knowledge of the system.  

The scope and methodology of a penetration test are typically determined based on the specific needs and objectives of the organisation. In any scenario, it’s a crucial component of a comprehensive cybersecurity strategy.

Why do you need penetration testing?  

Penetration testing is a crucial practice for organisations of all sizes, as it provides a proactive approach to identifying and mitigating potential cyber threats. By simulating real-world attacks, penetration testing helps uncover vulnerabilities that might otherwise remain undetected, such as weaknesses in network security, software flaws or human error.  

Penetration testing also plays a vital role in ensuring compliance with various industry regulations and standards. By demonstrating that they have taken steps to identify and address potential vulnerabilities, you can maintain compliance and avoid costly fines or penalties.    

Most crucially, penetration testing provides valuable insights into your overall security posture. The results of a penetration test can be used to prioritise investments, improve awareness and refine security policies. This allows you to continuously enhance your security defences and stay ahead of the evolving threat landscape.

Penetration testing FAQs_

What is the difference between vulnerability scanning and penetration testing?

Vulnerability scanning is like a basic health check. It automatically scans systems for known weaknesses based on predefined rules and databases. Think of it as a quick check for common issues. Penetration testing goes deeper. It’s like a thorough physical exam where a skilled professional actively tries to exploit vulnerabilities to understand the true impact and potential for compromise. 

How often should I conduct penetration testing?

The frequency depends on several factors, including the industry, the criticality of the systems and the regulatory requirements. For highly regulated industries or organisations handling sensitive data, frequent testing (e.g. quarterly or even monthly) is recommended. For others, annual testing might be sufficient. 

What are the different types of penetration testing methodologies?

There are three main types: 

  • Black box: The tester has no prior knowledge of the target system. This simulates a real-world attack by an external threat actor 
  • White box: The tester has full knowledge of the target system, including source code, network diagrams and internal documentation. This allows for a more in-depth analysis 
  • Grey box: The tester has limited knowledge of the target system, such as basic network topology or employee credentials. This approach provides a more realistic scenario. 

How can I prepare my organisation for a penetration test?

  • Document your systems and networks: This will help the testing team understand your environment better. 
  • Provide clear instructions and scope: Define the boundaries of the test and any restrictions. 
  • Ensure data backups: Protect critical data before the test begins. 
  • Communicate with employees: Inform employees about the upcoming test and its purpose. 

How much does penetration testing cost?

The cost varies significantly depending on several factors, including the scope of the test, the complexity of the target environment, the expertise of the testing team and the duration of the engagement.
