Trusting the effectiveness of your IT security controls is crucial to mitigate risks and malicious access to your systems and the information they store. Penetration testing is one of the most effective methods to gain assurance of your IT security.
Initiating a penetration test will give you the ability to develop (or enhance an existing) security strategy and remediate your vulnerabilities. You’ll gain confidence in your IT security knowing you understand and have visibility of the vulnerabilities in your IT systems and networks, and understand where remedial action is needed.
When looking for a penetration testing provider, it’s essential to have confidence in the skills and knowledge of the provider who performs your assessment. Choosing a CREST-approved penetration testing provider gives you the assurance that their cyber security services are of the highest quality and technical standards.
What is penetration testing?
Penetration testing is the process of methodically scrutinising an IT system’s security using similar techniques and tools that a malicious actor would use. Penetration testing is primarily used to gain assurance in the effectiveness of IT security controls and identify vulnerabilities.
Penetration testers are armed with the task of finding methods that an attacker can use to gain access to your computer network(s) and sensitive information. If you have a good understanding of your IT security controls, you may know some of the weaknesses your penetration test will find. In this case, the test can confirm your suspicions.
This will depend on the maturity of your organisation’s security strategy and how much internal investment you put into your security. Primarily, penetration testing is used to discover weaknesses that you weren’t aware existed, and will often confirm the extent of damage that may be caused by compromising them.
What is CREST?
CREST is an international not-for-profit accreditation and certification body that represents and supports the technical information security market.
Companies can choose to become a CREST member company and apply for CREST accredited services. The application requires a rigorous assessment of companies’ processes, data security and service methodologies to ensure they’re to a best practice standard.
Why and when do you need penetration testing?
A penetration test is needed to gain assurance in the effectiveness of your IT security controls to ensure a malicious actor can’t access or make changes to your systems and assets.
You may also require a penetration test for compliance reasons. Data regulations often require you to meet security standards that ensure Personally Identifiable Information (PII) is protected and secured within your IT environment to prevent data breaches or loss from occurring.
Conducting regular (often annual) testing is a common cycle for penetration testing. The frequency with which penetration testing is performed is dependent on the size, complexity, risk appetite and security budget of an organisation.
Regular testing ensures your security controls continue to reflect a changing environment. If you’ve had your systems in place for a while or have made significant changes, you might want to carry out a penetration test to determine its security posture.
You’ll learn whether your security is as effective as you expected or if it needs improvement to mitigate attacks.
How is penetration testing carried out?
Penetration testing is typically carried out by external, specialist testers. Penetration testers know how to initiate an attack using the tools and techniques malicious actors use. You should choose a CREST-accredited cyber security specialist with the knowledge and skills to target the right technologies and gain assurance in your desired areas.
Testing identifies weak security controls, misconfigurations and vulnerabilities within IT environments. This can include network devices, applications, remote access solutions, mobile devices, cloud and more.
At Sentrium, instigating a penetration test consists of the following steps:
The report you receive following your penetration test will cover the vulnerabilities found and how to remediate them effectively. Penetration testing is a heuristic process and the final report should document the findings in detail, as well as recommended actions; you shouldn’t expect to receive a pass or fail result.
Why is it important to use a CREST-approved provider?
Working with a CREST-approved penetration testing provider ensures you’re in safe and experienced hands. You should have the confidence that your penetration test is thorough and comprehensive. Your provider must carry out a test that’s technically accurate and covers the required scope of your IT controls to ensure your primary security concerns are assessed.
Legal issues are of high importance when conducting penetration testing. The testing company will know how to gain access to your IT systems and the weak spots within your security across the organisation that have been discovered in your test. Your penetration testing provider will need to seek specific authorisation from you to conduct the test.
The CREST accreditation gives you the assurance that your provider has the appropriate policies, processes and procedures to carry out penetration testing and protect your information. You can gain peace of mind that the support provided is the best in the industry.
