Frequently Asked Questions

ASM vs. VM: Key Concepts & Differences

What is attack surface management (ASM) and how does it differ from vulnerability management (VM)?

Attack surface management (ASM) focuses on discovering all assets—known and unknown—that could be exploited by attackers, including physical, digital, and human assets. ASM begins with asset discovery and provides a holistic view of your environment from an attacker’s perspective. Vulnerability management (VM), on the other hand, operates on a list of known assets and is concerned with identifying, classifying, prioritizing, and mitigating vulnerabilities in those assets. ASM is proactive and comprehensive, while VM is more reactive and limited to known assets. Source

Why is asset discovery important in attack surface management?

Asset discovery is crucial in ASM because it uncovers unknown, unmonitored, and unprotected assets that could be exploited by attackers. Without comprehensive discovery, organizations risk leaving critical assets exposed. ASM starts with discovery to ensure all entry points are identified and managed. Source

How does vulnerability management operate compared to ASM?

Vulnerability management operates on a list of known assets, using scanners to identify, classify, and mitigate vulnerabilities. It does not account for unknown assets or how assets are interconnected, which can leave gaps in security. ASM, in contrast, discovers all assets and considers their connections and dependencies. Source

What types of vulnerability scanners are used in VM?

Vulnerability management uses active and passive scanners. Active scanners test endpoints by simulating attacks, while passive scanners monitor operating systems, software, and services to understand data flows and potential weaknesses. Source

What are some limitations of vulnerability management?

Vulnerability management does not account for unknown cloud services, shadow IT, ad hoc implementations, merger and acquisition risks, outdated asset records, unpatched assets, and third-party supply chain connections. ASM addresses these gaps by discovering and managing all assets. Source

How does ASM help prioritize resources for remediation?

ASM provides guidance on where to prioritize resources by identifying assets most important to the organization and those most likely to be exploited by hackers. This enables targeted remediation and efficient use of security resources. Source

Is vulnerability management enough to secure modern enterprise environments?

No, vulnerability management alone is not enough. Modern environments are dynamic and dispersed, making it impossible to mitigate all entry points without visibility over the entire attack surface. ASM complements VM by discovering unknown assets and providing a holistic security approach. Source

How do ASM and VM complement each other?

ASM and VM work together to provide comprehensive security. ASM discovers unknown assets and their connections, while VM identifies and mitigates vulnerabilities in known assets. Using both ensures stronger protection against threats. Source

What is external attack surface management (EASM)?

Attack Surface Management vs. Vulnerability Management: What’s the Difference?

External Attack Surface Management

Attack surface management (ASM) and vulnerability management (VM) are often confused, but they’re not the same. The primary difference between the two is scope: Attack surface management and external attack surface management (EASM) assume that a company has many unknown assets and therefore begin with discovery. Vulnerability management, on the other hand, operates on the list of known assets.

What is Vulnerability Management?

A vulnerability is a weakness in an asset that could potentially be exploited by cyberattacks. Vulnerability management is a set of processes and tools a company uses to identify, classify, prioritize, and mitigate potentially exploitable vulnerabilities in systems or networks and provide visibility into your company’s cybersecurity health. This is done using vulnerability scanners, which can be active or passive:

  • Active vulnerability scanners test nodes or endpoints by sending transmissions and analyzing the responses to identify potential weaknesses. They can be used to simulate known attacks against a target in the way a potential attacker would try to carry out the attack, with the goal of uncovering security vulnerabilities.
  • Passive vulnerability scanners monitor operating systems that are in use, software, and the availability and status of services. This helps security teams understand what is being sent to and from the endpoints throughout a system or network.

Vulnerability management tools manage the workflow process, including assigning any mitigation tasks necessary to eliminate a potential weakness. These solutions focus on a single asset or a portion of your company’s overall IT environment without concern about how assets are interconnected and how a weakness in one asset could impact other assets.

What is Attack Surface Management?

An attack surface is the total of all assets — physical, digital, and human — and weaknesses in a company’s environment that could be exploited by attackers. It encompasses all assets that are accessible from the internet. Attack surface visibility aims to discover and expose the risks of unknown, unmonitored, and unprotected assets.

Attack surface management provides a more holistic view of what your company’s environment looks like from the outside, from an attacker’s perspective. ASM considers both internal and exposed assets, and it understands how assets are connected and the potential impacts a breach of one asset could impact other assets. 

Attack surface management also provides guidance on where to prioritize your resources to address issues on assets that are important to your organization and assets hackers are most likely to exploit.

Isn’t Vulnerability Management Enough?

According to the National Institute of Standards and Technology (NIST), there were 18,378 vulnerabilities reported in 2021. Modern enterprise environments are dynamic, dispersed, and growing, making it impossible for security teams to mitigate all potential entry points. Companies need visibility over the entire attack surface to protect it adequately.

There are many things vulnerability management doesn’t account for, including:

  • Unknown cloud services, web applications, mail servers, etc.
  • Shadow IT
  • Ad hoc implementation
  • Merger and acquisition risk evaluations
  • Not up-to-date asset records
  • Introductions of unpatched and untested assets
  • Out-of-date and vulnerable operating systems
  • Third-party applications
  • Third-party supply chain connections

Attack Surface Management vs. Vulnerability Management: Key Differences

Vulnerability management is a subset of ASM/EASM. However, because attack surface management is a new market that emerged in mid-2021, it’s considered part of the vulnerability management market in terms of market size and value.

There are several key differences between attack surface management and vulnerability management. First, vulnerability management manages what you know, while attack surface management finds what you have.

Vulnerability management also doesn’t consider how assets are connected and how a vulnerability impacting one asset can impact others. ASM, on the other hand, is more proactive, providing a holistic view of your company’s assets and the threats they face. Attack surface management considers how networks, applications, and assets are connected and covers all entry points throughout your company’s IT infrastructure, applications, APIs, data, etc.

IONIX is an attack surface management platform that goes further to discover your exposure, identifying your internet-facing assets, how they’re connected, and mapping your attack surface. 

IONIX multi-layered vulnerability assessment engine provides continuous vulnerability and risk identification, ranking, and prioritization, so you can focus on your biggest risks. Active Protection freezes your most vulnerable assets in your supply chain, stopping attackers in their tracks until your security team can mitigate the risk.   

Final Thoughts

Attack surface management and vulnerability management work together. If you’re employing attack surface management, you’re also employing vulnerability management, as both address vulnerabilities — but in different ways. Vulnerability management and attack surface management complement one another and are stronger together.

Vulnerability management provides insights into your known assets and what threats they face in isolation, while external attack surface management solutions like IONIX discover assets you didn’t know you had. IONIX provides a comprehensive view of your company’s assets, how they’re connected, and what threats they face, as well as what risks an attack on one asset could pose to other connected assets.
