Attack Surface

What is an Attack Surface?

In the digital age, cyber security is a critical concern for both individuals and businesses. Cybersecurity is the practice of protecting internet-connected systems such as hardware, software, and data from malicious attacks. It encompasses a body of techniques used to protect sensitive data, personally identifiable information, computer systems, networks and other electronic systems from unauthorized access or damage. Cyber security professionals are tasked with defending computer systems against different types of cyber threats that can hit businesses and private systems alike. As our society has become increasingly dependent on computer networks and information technology solutions, cyber attacks have become more frequent and sophisticated in nature. To better understand how to identify potential threats and protect against them it is important to understand the concept of an attack surface.

What is an Attack Surface?

An attack surface is a collection of resources, systems, and services that can be manipulated and exploited by malicious actors. This includes software, hardware, networks, databases, applications and any other system that can be accessed by a potential attacker. Every system has an attack surface which can be targeted by malicious actors. A physical attack surface includes access to all endpoint devices such as desktop systems, laptops, mobile devices and USB ports as well as improperly discarded hard drives. Attack surface management in software applications aims to detect weaknesses in the system and reduce the number of exploitable vulnerabilities.

Attack surfaces are sometimes referred to as attack vectors which are Vulnerabilities that allow unauthorized access or actions on a system or network when exploited by cyber attacks. Vulnerabilities are weaknesses in the system that can be used for malicious purposes if not managed properly. An organization’s attack surface encompasses all externally visible areas of their network or system which could potentially be vulnerable to cyber attacks.

In order to protect against these threats it is important for organizations to understand their own attack surfaces so they can identify potential risks before they become serious issues. This involves assessing all aspects of the environment including hardware components such as servers and routers; software components such as operating systems; networks; databases; applications; user accounts; authentication methods; encryption protocols etc., so any weak points can be identified and addressed before they become targets for attackers. Organizations should also regularly review their security policies and procedures in order to ensure they remain up-to-date with current best practices for protecting against cyber threats.

How Does an Attack Surface Work?

An attack surface is a potential entry point for malicious actors to gain access to a system. Attack surfaces can be exploited through various methods, such as exploiting vulnerabilities, misconfigured systems, or phishing techniques. Cyber attack vectors are the methods or ways an adversary can breach or infiltrate an entire network/system. Common cyber attack vectors include viruses and malware, email attachments, and indirect attack vectors such as browser vulnerabilities. Vulnerabilities are weaknesses that can be exploited by a cyber attack to gain unauthorized access or perform unauthorized actions on a system. Attack surface reduction is the best way to mitigate cybersecurity risks by securing vulnerable attack vectors and removing any unnecessary ones sometimes referred to as “attack surfaces”. Indirect attack vectors involve exploiting vulnerabilities in other systems via an Internet browser vulnerability in order to gain access to the target system. By understanding how these different types of attacks work together, organizations can better protect their networks from malicious actors and reduce their overall risk of being compromised.

How Can an Attack Surface Be Used to Identify Cyber Threats?

Organizations can use the attack surface to identify potential cyber threats and develop a comprehensive security strategy. Attack surface management in software applications helps detect weaknesses in a system and reduce the number of exploitable vulnerabilities. An attack surface is defined as the total number of all possible entry points for unauthorized access into any system, including all vulnerabilities and sometimes called attack vectors. Attack surface analysis is the process of mapping out what parts of an organization are vulnerable and need to be tested for security vulnerabilities. Weak passwords and password reuse make credential exposure a gateway for initial attacker access and propagation, as seen with recent malware attacks such as Mirai. By understanding their attack surfaces, organizations can take action to protect their systems by implementing multiple layers of defense such as firewalls, anti-virus software, user education, strong passwords, and monitoring for changes or new threats that may arise.


In conclusion, attack surface is a collection of resources, systems, and services that can be manipulated and exploited by malicious actors. Attack surface management refers to the continuous surveillance and vigilance required to mitigate all current and future cyberthreats. Attack surface analysis is the process of mapping out what parts of an organization are vulnerable and need to be tested for security vulnerabilities. In very simple terms, attack surface is the collection of all potential vulnerabilities which, if exploited, can allow unauthorized access to the system. Attack vectors or breaches defined as points on a network where attacks can occur are also part of an attack surface model which contains all of the attack vectors (or vulnerabilities) a hacker could use to gain access into a system. Organizations must understand their attack surfaces in order to develop comprehensive security strategies that protect their systems from potential cyber threats. By doing so they can ensure their systems remain secure from malicious actors who seek unauthorized access into their networks.
