An attack surface is the collection of vulnerabilities, misconfigurations, and entry points that an attacker can exploit to gain access to a target system or environment. It includes both external and internal components, defined by their location and accessibility within an organization. Source
The three main types of attack surfaces are: Digital (websites, applications, APIs, cloud services), Physical (servers, USB drives, hardware), and Social (social engineering, phishing). Each type presents unique risks and requires specific security measures. Source
Common components include web apps, APIs, operating systems, cloud resources, workstations, servers, mobile and IoT devices, network infrastructure, employees, contractors, and third-party suppliers or vendors. Source
An attack surface refers to all potential entry points for attackers, while each individual entry point is an attack vector. For example, a website is part of the attack surface, and an SQL injection vulnerability on that website is an attack vector. Source
Understanding the attack surface helps organizations identify and remediate vulnerabilities, reducing the risk of cyberattacks. Each remediated attack vector removes an opportunity for attackers to gain access, raising the difficulty and cost of a successful attack. Source
Attack surface monitoring is the practice of continuously tracking an organization’s attack surfaces to maintain visibility into current threats and risks. This enables security teams to manage risks proactively and focus remediation efforts effectively. Source
Best practices include continuous monitoring, implementing least privilege, patching regularly, educating employees, using strong authentication (such as MFA), and managing IT assets with physical protections. Source
ASM is the practice of monitoring all attack surfaces within an organization. Key elements include asset discovery, vulnerability assessment, threat prioritization, vulnerability mitigation, and continuous monitoring. Source
EASM focuses on managing an organization’s Internet-facing attack surface. It aims to reduce the risk of external attacks by identifying unknown assets, shadow IT, third-party risks, and misconfigurations in public-facing services. Source

Vulnerability assessment involves searching for potential attack vectors, focusing on vulnerabilities and misconfigurations in digital, physical, and social attack surfaces. It is a critical step in ASM. Source
Threat prioritization assesses the risk posed by each attack vector based on its potential impact and likelihood of exploitation. Security teams use prioritized lists to address the most significant risks first. Source
Continuous monitoring ensures that the prioritized list of attack vectors is always up-to-date, preventing security teams from missing emerging threats due to outdated information. Source
EASM identifies and manages risks associated with third-party suppliers, partners, and vendors by detecting unknown assets, shadow IT, and misconfigurations in Internet-facing services. Source

An attack surface is the collection of vulnerabilities, misconfigurations, and other entry points that an attacker can exploit to gain access to a target system or environment. Organizations may have both external and internal attack surfaces, defined by their location in the organization’s environment and the parties that can access them.
In this article
The goal of attack surface management (ASM) is to identify these various attack vectors and shrink the organization’s attack surfaces as much as possible. This reduces the attacker’s ability to gain initial access to an organization’s environment or expand their access to new systems.
An attack surface includes every potential entry point that an attacker can use. Attack surfaces can be broken into three main categories, including:
An organization’s attack surface includes every potential entry point for an attacker into an organization’s environment and systems. Some common components of an attack surface include:
The terms “attack surface” and “attack vector” are related but distinct concepts. An attack surface refers to all of the potential entry points that an attacker could use to exploit an organization. Each of these individual entry points is an attack vector. For example, a corporate website may be part of an organization’s attack surface. On this website, an SQL injection vulnerability is a potential attack vector.
Most cyberattacks originate from outside the organization. Cyber threat actors need to gain initial access to an organization’s environment and systems to expand their footprint and achieve their operational objectives.
This initial access is achieved by exploiting one or more potential attack vectors that make up the organization’s attack surface. This could include exploiting a software vulnerability, performing a social engineering attack, or gaining physical access to a corporate system.
Organizations need to understand their attack surface in order to protect themselves against these attacks. Each attack vector that the organization can identify and remediate offers an attacker one less opportunity to gain that initial access to the organization’s systems. By raising the difficulty of a potential attack, the company reduces the risk that an attacker will have the knowledge, resources, and time required to successfully carry it out.
Corporate attack surfaces are constantly evolving as the organization changes. Each new piece of software or updated code may introduce new vulnerabilities into the organization’s environment. Companies may also be vulnerable to new social engineering threats due to new hires, new threats, or the use of different communications platforms.
Attack surface monitoring is the practice of monitoring an organization’s attack surfaces. By doing so, the company maintains visibility into its current threats and risks, providing useful insights for risk management and enabling security teams to appropriately focus their efforts to manage these risks.
ASM is the practice of monitoring all of an organization’s attack surfaces. Some key elements of this include:
External ASM is a facet of ASM focused solely on addressing an organization’s Internet-facing attack surface. Its primary goal is to reduce the risk that an attacker will be able to gain any access to an organization’s environment, minimizing the threat to the business
EASM uses many of the same techniques as ASM but has particular areas of focus, including:
Reducing its attack surface is one of the most effective ways that an organization can manage the threat of cyberattacks to the business. Some best practices for doing so include:
ASM is critical to managing an organization’s exposure to cyberattacks. Security teams need real-time visibility into their attack surface so that they can close security gaps and detect and remediate potential attacks.
