Attack Surface Management explained

by Sebastiaan Bosman Blog 7 Jan 2021

It's the term we use the most: Attack Surface Management. It is the foundation of your organisation’s digital infrastructure. It’s the starting point of your IT security policies, configuration database management, vulnerability mitigation, and much more.

In this blog, we’ll shortly describe what drives the need for an Attack Surface Management solution, share our definition of the term attack surface, and explain how it minimises the risks to your brand.


Why is attack surface management important?

A solution is only helpful if it solves a problem. The need for any IT security tool is driven by external factors. We see three major influences:

  1. Threat evolution
  2. Technology evolution
  3. Regulatory trends

Threat evolution is about the way criminals try to obtain data or money and how you can defend yourself from these methods. This is a constant back-and-forth. Close one door, and threat actors will try to enter through a different one. Though no organisation is 100% cyber-secure, understanding where threats are coming from and taking preventative measures is a continuous necessity.

Technology evolution is mostly about digitisation. Organisations undergo digital transformations and move more services and infrastructure to cloud environments and external suppliers. This makes monitoring and managing the different systems more complex as well.

Regulatory trends dictate to what standards organisations must comply. These compulsory measures can come from insurance companies, governmental bodies, or market authorities. For example, the European Banking Authority has made the measurable management of third parties in your supply chain obligatory for financial organisations.

There is a place where these three factors come together and mix with the rest of your organisation: your attack surface.

What is an attack surface?

We define an attack surface as a compilation of all digital assets related to the brand. This includes your domains, third parties, netblocks, shadow IT, but also external phishing websites, brand abuse, and supply chain risk. Furthermore, we define an attack surface on the basis of a few characteristics:

Firstly, it’s important to understand that any organisation’s attack surface is a dynamic thing. It is always evolving, growing and shrinking in different parts, it’s differently interpretable and contextual. And almost always is it bigger than estimated.

As an attack surface is so dynamic, the typical static analyses of digital assets just won’t cut it as you’ll be falling behind on the data. Even selecting the data to check wields blind spots, as you most likely have some sort of shadow IT.

That’s why our Attack Surface Management solution works without a pre-defined IT space, and finds the assets related to your brand for you. We call this outside-in method a zero-scope approach.

Secondly, identifying and mapping the assets in the attack surface is simply too time-consuming to do manually. That is why our AI-powered platform works automated and continuously, yet is still guided by Analyst Intelligence (AI²) for optimal queries and results. It allows for faster asset inventory and managing on exceptions. And as it operates in the cloud, there is no installment necessary. We call this zero-touch. 

From digital risk to business risk

The data coming from our Attack Surface Management platform does not only help you mitigate cyber-risks to strengthen your security, it also provides the insights into the efficiency of systems and tools you already have. And with risk-over-time analyses, you’ll be able to see which governance processes work and which are in need of an update.

Having the right insights into your attack surface will benefit your whole organisation. Protecting your employees, customers, and brand is critical. Combining that with the information needed to make data-driven business decisions makes an attack surface solution the main starting point of any IT process.

Editorial: Exchange CVEs: The Response Plan Gap

It’s been two weeks since Microsoft released a patch for the Exchange vulnerabilities. For many, the dust has settled. Others are still fighting fires. Today, I’d like to look back at some of the problems we saw. Some were expected, other surprised us. I’ll go over them, and give tips on how these problems can be avoided in the future.

Editorial: Supply chain attacks

Today, supply chain attacks are as abundant as they are elusive. However, as many parties communicate about the dangers and their technical solutions, not much is said about the basics of supply chains attacks. I have written this article based on my personal experiences knowledge on the subject. I hope it answers most of your questions about the topic, so that you have a solid basis to expand your supply chain security from.

Attack Surface Management compared to 5 security technologies

In this blog, we'll cover our attack surface management approach compared to five existing security approaches. What methods do they share? And where do they complement each other? We'll have a look at these techniques:  1. Asset discovery 2. Vulnerability management 3. Penetration testing 4. Red teaming 5. Supplier security governance Each has some touch points with attack surface management. For this comparison, we build on our earlier explanations of the concept. In the first blog, we gave our definition and summarised what drives the need for the solution. You can read our second blog to see how attack surface management is positioned with regards to External Threat Intelligence.
