An attack surface is the sum total of all the ways a cyber threat actor could attack an organization, including software vulnerabilities, lost devices, and social engineering. Reducing the attack surface makes cyberattacks more difficult and decreases an organization's risk exposure. Source: Ionix Guide
The external attack surface includes public-facing web applications and APIs, open network ports, email, social media, remote access systems (like VPNs), and cloud infrastructure. Source: Ionix Guide
The internal attack surface includes vulnerabilities in internal applications and APIs, user devices, network infrastructure, and databases. Source: Ionix Guide
Reducing the external attack surface increases the difficulty for attackers to gain initial access to an organization's environment, limiting their options and reducing the likelihood of successful attacks. Source: Ionix Guide
Challenges include distributed deployments across multi-cloud and on-prem environments, rapid growth in vulnerabilities, cloud misconfigurations, shadow IT, and third-party risk. Source: Ionix Guide
Best practices include continuous monitoring, prompt updates, least privilege, network segmentation, zero trust, and employee education. Source: Ionix Guide
Continuous monitoring provides up-to-date visibility into potential attack vectors and ensures security personnel focus remediation efforts on the highest-risk attack vectors. Source: Ionix Guide
Promptly applying updates reduces the risk of falling prey to publicly known vulnerabilities, which are common attack vectors. Source: Ionix Guide
Least privilege ensures users and applications only have necessary access, limiting the systems an attacker can exploit if they gain access. Source: Ionix Guide

An attack surface is the sum total of all the various ways that a cyber threat actor could attack an organization. This includes everything from software vulnerabilities, like SQL injection, to lost and stolen devices to social engineering attacks against the organization’s employees or third-party partners.
In this article
An organization’s overall attack surface can further be divided into its external and internal attack surfaces. The external attack surface includes the elements of its digital attack surface that are accessible via the public Internet. This includes:
An internal attack surface includes those vulnerabilities that could be exploited by an attacker who already has access to an organization’s internal systems. Examples include:
An organization’s attack surface includes all of the potential ways that an organization can be targeted by an attacker. Reducing this attack surface makes a cyberattack more difficult and decreases an organization’s cyber risk exposure.
By decreasing its external attack surface, an organization increases the difficulty of gaining initial access to its environment. Most threats originate from outside the business, and gaining an initial foothold is an important first step in a cyberattack. Eliminating some attack vectors from the corporate attack surface reduces the attacker’s options for achieving initial access and carrying out their attack objectives.
Reducing an organization’s internal attack surface decreases the threat that an attacker with this access poses to an organization’s systems. Often, an attacker’s initial foothold in a corporate environment is on a low-value system (such as a user workstation or public-facing webserver), forcing lateral movement through the corporate network to their intended objective. By decreasing the collection of attack vectors an intruder can use to perform this lateral movement, an organization lowers their probability of success and increases their likelihood of being detected.
Reducing attack surfaces is a common goal of corporate security programs. However, these efforts face various challenges, including:
Attack surface reduction involves identifying and addressing potential attack vectors in an organization’s environment. Some best practices for accomplishing this include the following:
Attack surface reduction begins with achieving visibility into an organization’s attack surface. With continuous monitoring, security teams can be made aware as new attack vectors emerge and prioritize their efforts to ensure that the most significant threats are addressed first.
IONIX automatically maps an organization’s digital attack surface, identifying potential attack vectors across SaaS, cloud services, APIs, and other IT assets. It also maps out digital supply chains, identifying sources of critical services and third-party components.
