You can read more about each of these systems in the following sections.

Attack surface monitoring tools provide Attack Surface Management (ASM). This is a continuous process because there are new exploits discovered all of the time. ASM involves two phases of research. First, you need to know what data you hold and what sensitivity ranking each piece of data holds. Secondly, you need to have an accurate software inventory.

With complete system documentation in place, an attack surface monitoring tool can start to search for the typical inroads that hackers are known to use. DevOps environments can integrate ASM into their CI/CD pipeline to head off potential problems with new functions and features.

Attack surface monitoring

The development of new attack strategies by hackers means that attack surface monitoring can’t sit still. You also have an issue with further data services and software packages to watch over. No system is static, and so attack surface monitoring needs to be an ongoing task.

The field of attack surface monitoring is relatively new. There aren’t many tools available for this task at the moment. If you are not satisfied with the few attack surface monitoring tools currently available, you could rely on a vulnerability scanner because some of these also cover software vulnerabilities.

One step back from outright attack surface monitoring and vulnerability management, you could rely on Intrusion Detection Systems (IDSs). These look for any malicious activity on your system, including data theft events. Another category of software that would come in useful as an attack surface monitoring substitute is data loss prevention (DLP). The critical aim of attack surface monitoring is to protect data stores from unauthorized access, which is the same as DLP systems.

The best attack surface monitoring tools

The blur between vulnerability management and attack surface management means that some vulnerability scanners advertise themselves as attack surface monitors. At the same time, many vulnerability managers also offer attack surface monitoring without explicitly using that term in their product descriptions.

Our methodology for selecting an Attack surface monitoring tool

We reviewed the market for attack surface monitors and analyzed the options based on the following criteria:

  • A system that checks software for vulnerabilities
  • A service that identifies out-of-date software versions
  • A monitoring tool that logs data access by software
  • A monitor that can distinguish between valid user activity and suspicious account activity
  • A service that reduces the risk of sensitive data loss or disclosure
  • A free trial or a demo version for a no-cost assessment
  • A comprehensive tool that protects sensitive data by identifying software security weaknesses

As the term “attack surface” is relatively new. We don’t rely on that phrase being in the name or description of a security system included in our considerations.

Bugcrowd Attack Surface Management provides an asset discovery tool that assembles an inventory of both hardware and software. The software inventory forms the foundation for a vulnerability scanner. The company acts as an agency for independent white hat hackers and it gathers their reports on discovered exploits into this vulnerability management service.

Bugcrowd explains that a third of all attacks get into a business through software and services that the company’s IT department doesn’t even know that they are using. You can’t protect systems that you don’t see that you use. The system then watches over those newly-discovered assets and alerts the client if it detects any security risks on them.

Customers who want a tailored service can commission human-based searches of their system. This is an actual pen-testing exercise because Bugcrowd puts a bounty on your company’s systems and invites some of the leading whiter hat hackers worldwide to break in, awarding the prize to the first hacker in. This service is called Asset Risk.

Who is it recommended for?

This tool is a good choice for businesses of all sizes. The company doesn’t publish its price list, so small businesses will probably steer clear of this option lest they get stung with a large bill.

  • Innovative Attack Database: Leverages a comprehensive database of imminent hacker campaigns gathered from the Dark Web.
  • Remote Operation Capability: Monitors digital assets remotely, offering protection without the need for onsite deployment.
  • Hacker Technique Modeling: Utilizes advanced modeling to predict and counteract hacker strategies before they are implemented.

Why do we recommend it?

ReliaQuest GreyMatter Digital Risk Protection compiles a database of discovered attack plans, which it scrapes from the Dark Web. So, rather than scanning a client system for a list of hacker methods, such as the OWASP Top 10, it looks for vulnerabilities to attack campaigns that are about to happen.

You register your outward-facing assets on taking out this service, such as brands, product names, IP addresses, and domains. The SearchLight system then keeps a constant eye out for mentions of these names and addresses. An example of the kind of information that the service can pick up would be the contact details or even the system login credentials of an employee being circulated on the Dark Web.

SearchLight analysts, using crawler and data analysis tools, identify potential attacks on one of the clients that they protect. The type of data detected on a client indicates the direction that an attack will take. With this warning, SearchLight can inform the client of the upcoming episode and which parts of the system to harden in defense.

Who is it recommended for?

This service is an important protection system for any business but it is particularly important for very large, noticeable businesses that have well-known brands. Big companies have more assets that can be attacked and their large incomes make them bigger targets. A well-known brand is also very vulnerable to reputational damage.

Pros:

  • Simplified Asset Registration: Allows for easy setup by entering brand, product, IP addresses, and domain information on a webpage.
  • Proactive Campaign Tracking: Keeps tabs on current hacker campaigns, offering insights into potential threats.
  • Dark Web Intelligence: Scans the Dark Web for mentions and threats related to your digital assets, providing timely alerts.

  • Hybrid Analysis Approach: Combines automated software with manual expert analysis for comprehensive coverage.
  • API and Plugin Specialization: Specifically targets the security of third-party APIs and plug-ins to mitigate risks.

Why do we recommend it?

CoalFire Attack Surface Management is a managed security service. Not only does the package include all of the software and the servers that run it, but the bundle also provides technicians to manage the system. While the software runs continuously looking for vulnerabilities, the experts shut down all loopholes and construct a fightback strategy.

Once a website is up and running, it is tough to unpick and rewrite it. For one thing, such an exercise would be very costly and difficult to justify to the company accountant. CoalFire crawls through websites and lists all of the external services that they have integrated. While automated processes discover all of the chains of assets that contribute towards a client’s systems, human analysts verify these findings.

With the complete asset inventory in place, the business can develop a defense strategy. CoalFire doesn’t include a SIEM or an intrusion detection system. However, it gives you guidance on the correct defense software that you need for your digital profile.

Who is it recommended for?

This is a useful service for businesses that are located in places that have almost no available security talent to hire. It could also be a good proposition for small and mid-sized companies that can’t afford to set up a security operations center. The service can be tailored for compliance management.

OWASP provides the definitive list of vulnerabilities for which to scan, which is the OWASP Top 10 and so using a vulnerability tester from the organization is a very attractive proposition. However, this is a pen-testing tool rather than a vulnerability scanner.

The second project of OWASP that can be plugged into the Zed Attack Proxy makes it an attack surface monitor. This is the Attack Surface Detector. This service can trace through APIs and Web services, making it a great discovery tool for attack surface analysis.

The Detector locates the hosts for discovered applications, and then it notes the parameters for the call and their data types. Another valuable feature of the Detector is that it will scan an app and store its code. The system can be used to regularly rescan those discovered functions and compare its code to the stored version, identifying changes that could introduce new vulnerabilities or even include new backend functions to trace through to.

Who is it recommended for?

This tool isn’t really a cost saver for small businesses because it isn’t an automated system that anyone can sign up for and set running. You need a security expert to run tests with this tool and interpret its results. So, this is a system for use by penetration testers.

Pros:

  • Integrated Attack Surface Analysis: When paired with the Attack Surface Detector, it becomes a powerful tool for uncovering and monitoring web app vulnerabilities.
  • Control Over Scanning: The on-premises deployment option puts you in complete command of the scanning process.

Attack Surface Monitoring FAQs

What is an attack surface management?

Attack surface management examines your systems from the perspective of an outside. Could a remote miscreant break into your system? How would that be done? Where are the weak links in your external digital edifice? An attack surface manager first identifies all of your digital assets that can be reached without insider privileges and maps all discoverable dependencies. It then looks for ways in and will also keep an ear to the ground to detect whether a hacker group is currently on the hunt for a specific type of system or organization.

How is attack surface measured?

An attack surface is the external digital profile of a business – anything that can be accessed without authorization. There is no benchmark for the success of an attack surface manager and no definitive list of weaknesses to look out for. However, any weak points should be logged and ranked for severity.

What is attack surface analysis?

Attack surface analysis requires the application of assessments with projections for possible weaknesses rather than a checklist of known vulnerabilities. For example, a module might be secure, but that strength might be compromised when combined with specific actions or associated data exchanging facilities. Attack surface analysis requires heuristics, which can best be applied through a combination of automated and human assessments.
