Continuous Pen Testing: A Deeper Dive

Penetration testing, often referred to as pen testing, is frequently viewed as a trade-off between simplicity and effectiveness. The general perception is that the more often you conduct pen testing, the better. Nowadays, with e-commerce serving as the primary platform for accessing essential services, businesses of all sizes are striving to enhance and automate their online operations. Consequently, it is imperative to prioritise the protection of customer data, safeguard business reputation, and fortify defences against cyber breaches. Read more about the differences in pen testing and why we recommend continuous pen testing.

 

Single pen tests – a snapshot in time

One-off pen tests are highly effective as a one-off static picture; they can validate requirements, prove compliance and achieve PCI-DSS.

But businesses don’t stay static and neither does the cyber-attack landscape.

A single pen test proves that your house is secure at that moment in time, but 24 hours later something might have changed, and someone could break in.

 

Repeat pen testing – the power of comparison

“The main benefit of repeat pen testing is the ability to see that something has changed”

Repeat penetration testing, eg 2-4 times a year or once a month, still only proves that you’re secure at the point of the test. However, the main benefit of this more regular testing regimen is the ability to see that something has changed.

On an ongoing basis, this demonstrates risk levels and highlights to you where focus is needed. It’s also a very powerful part of a change control process, showing you whether and where you’ve introduced vulnerability by making alterations to the environment. Ideally, pen testing should be performed before and after a change is made, which again has the benefit of showing you a direct comparison and exposing vulnerabilities quickly.

Frequent app updates need frequent checking: In the world of app development, everything happens so quickly and on such a large scale that things can go wrong at the same magnitude. The frequency of changes in automated app updates, sometimes occurring multiple times a day, means that penetration testing needs to be included in the update process. The modern approach to DevOps no longer involves issuing periodic app updates and bug fixes. Instead, use continuous integration and continuous deployment (CICD) processes to automate ongoing development. This results in iterative changes that can be difficult to track. However, these changes can introduce security vulnerabilities that may impact your overall cyber security posture.

Continuous pen testing for effective network profiling

The gold standard for penetration testing has evolved to become a continuous process, moving beyond a one-time assessment to an ongoing monitoring of vulnerabilities and intelligence gathering. By conducting penetration tests regularly, you gain deeper insights into the operating systems, applications, and technologies in your network. This allows you to proactively assess vulnerabilities based on CVE notifications.

Continuous pen testing has the power to become an ongoing vulnerability monitoring and intelligence capability.

The latest pen-testing products can now automate the pen-testing process through APIs as part of the deployment. This provides notifications of any changes and potential vulnerabilities introduced. If a change causes vulnerabilities, the product can identify the responsible update and automatically roll back to the trouble-free version.

 

Beyond pen testing for a dynamic vulnerability assessment capability

As part of the implementation process, the user specifies what range of IPs they want to scan and how many devices are in that range. A top-level pen testing product will also proactively monitor other software and devices that get connected to that subnet, 24/7. These can then automatically be pen-tested as they connect, and become part of your CICD development process.

Penetration testing tools can integrate with MDR and XDR solutions to enable automated detection and response. The insights provided by the pen testing regime can be used to patch and fix problems as they occur.

 

Ultimately, continuous penetration testing has the potential to evolve into an automated, intelligent, and fully integrated component of a comprehensive cybersecurity stack. It can identify, track, and neutralize hacking activity before it breaches your data and impacts your organization.

The IT and Cyber Security landscape has undergone significant changes in recent years. One prominent change is Citrix shifting their focus from the load-balancing space to more towards other areas, as evidenced by acquisitions like Wrike, a project management company, and the end-of-sale announcement for NetScaler Perpetual Licenses.
Certificate management is a critical part of an organisation’s cyber security that cannot be ignored. Certificates are vital for protecting data transmitted between websites and users. If not properly managed, data could be at significant risk. One certificate option that organisations often consider is wildcard certificates, which provide some benefits but also carry security risks.
Google's announcement to reduce the lifespan of Transport Layer Security (TLS) certificates from 398 days to 90 days continues to be a hot topic of discussion among information security professionals, especially those directly involved in replacing and updating certificates. It’s especially frustrating because – although mooted back in April of 2023 – there’s still no confirmed date for its implementation. Yet Chrome browsers account for just over 50% of all UK web traffic (Statista), so there’s no avoiding the impact that this will have.
