Attack Surface Management

The constant finding, inventory, categorization, priority, and surveillance tracking of outermost digital possessions that store, send, or handle confidential data is known as attack surface management (ASM). 

In essence, it is everything that an adversary can and will learn about outer of the firewall as they scout out susceptible companies in the potential danger environment.

As a leading part of a comprehensive cybersecurity risk management scheme, it is advised that security executives commence lowering, tracking, and controlling their attack areas in 2018. Your attack surface has exponentially increased and gotten immensely tougher to describe and protect as a result of the hurry toward digital change. 

In addition to the surge in cyberattacks and leaks, it makes sense why attack surface control is receiving attention. Managing the attack area is currently a top concern for safety teams, CISOs, CIOs, and CTOs. 

In today's guide to ASM, we will discuss the overview of the attack surface, external attack surface management working strategies, and many more.

Attack Surface Management

What is Attack Surface?

The attack surface is made up of all the Internet-accessible cloud, SaaS, and software possessions that handle or keep your data. You may consider this the number of attack paths hackers could employ to trick a chain or structure into giving up data. Your strike area entails:

Known possessions 

Precise and controlled resources like your company's website, servers, and the requirements they support. 

Non-recognized assets 

As an example, you must consider Shadow IT or a deserted ecosystem of information technology that established outer the scope of your safety team, such as abandoned headway websites or marketing sites.

Unauthorized assets

Assailants create nefarious facilities such as ransomware, fake domains, or a website or mobile application that uses your name as its front.


Third and fourth-party suppliers significantly increase third- and fourth-party exposure, expanding your company's attack area. Consider the HVAC vendor who ultimately resulted in Target exposing the credit card and confidential information of over 110 million customers as an example of how even tiny vendors can result in significant data contraventions.

These possessions, which number in the millions daily, fall beyond the purview of firewall and device security solutions. Outermost strike interface and digital interface are some alternate terms. 

Attack Surface Management definition

It is the process of constant identification, surveillance, assessment, setting of goals, and correction of assault routes within a company's information technology system.

ASM, which is a frequently considered a part of the IT hygiene remediation process by cybersecurity experts, aims at identifying threats and management of vulnerabilities from the standpoint of the perpetrator. 

By doing this, the organization is motivated to recognize and assess the risk presented not only by recognized possessions but also by unidentified and renegade elements.

How does Attack Surface Management work?

The four fundamental ASM procedures are asset finding, categorization and prioritization, rehabilitation, and tracking. Again, these steps are conducted continuously, and cyber attack surface management strategies automate these processes whenever feasible as the size and form of the digital assaults area shift thoroughly. 

The objective is to speed up the reaction to the flaws and hazards that give rise to the largest risk to the organization and to guarantee that the safety squad always has a full and up-to-date list of vulnerable assets.

  1. Discovery

Finding all Internet-based digital possessions that store or handle your private data, for example, PII, PHI, and confidential information, is the first step in any attack surface management solution. 

These resources may be held or managed by your organization alongside the independent freelancers, suppliers, business collaborators, and IaaS and SaaS providers. 

Attack surface management tools or an attack surface control tool should identify and record the cyber-assets enlisted below:

  • Internet of Things and linked devices
  • Services, web apps, and APIs
  • Email servers
  • Network devices and cloud repositories
  • Mobile apps and the backends
  • SSL certificates, domain names, and IP addresses 
  1. Analysis and classification

Commodities are first discovered, then categorized, examined for weaknesses, and ranked according to their "attack ability"—a numerical indicator of the likelihood that hackers will attack them.

Assets in the IT system are classified according to their name, IP location, ownership, and links to other assets. They are examined for potential vulnerabilities, the reasons behind those vulnerabilities (such as coding mistakes, glitches, and absent patches), and the types of cyberattacks that hackers might employ these vulnerabilities to launch (for example, pilfering sensitive data, disseminating ransomware or other adware). 

  1. Testing

As more devices are linked, users are incorporated, and the company develops, the assault zone alters continuously. As a result, it's critical that the tool must be capable of continuous evolution and attack area tracking. A contemporary attack surface management system will continuously evaluate and assess assets to stop the emergence of brand-new security flaws, spot safety holes, and get rid of configuration errors and other potential hazards.

  1. Prioritize

The company needs a method of prioritizing cleanup endeavors for current susceptibilities and weak points, as the ASM system is designed to find and catalog every IT belongings. Based on a variety of criteria, including the degree to which a vulnerability is exploitation-ready, how easy it is to abuse, how difficult it is to mitigate the risk, and the past of exploitation, ASM offers practical risk scoring and protection scores. 

  1. Remediation

The IT staff is now fully furnished to detect the most serious threats and prioritize remedying them in terms of the automatic steps in the first five stages of the ASM program. It's crucial to know that the details are shared through each function and that everyone on the team is in agreement regarding safety operations because these initiatives are frequently managed by IT teams rather than cybersecurity experts.

Attack Surface Management scheme of work

Who is the attack surface management software being created for? 

This ASM software is created for:

  • Compliance Administrators

Compliance officials use this ASM software to make sure that the companies abide by any relevant safety and discreetness of information laws or regulations.

  • Penetration Testers

They use this ASM software extensively to model actual assaults on the apps and ecosystem of a company. By doing so, they can evaluate the efficacy of the controls already in place in a given setting and find any vulnerabilities that an assaulter might leverage.

  • Network Administrators 

They are in charge of organizing and looking after the network that their company employs. They find any possible weaknesses in the ecosystem using attack surface management tools and take action to plug those openings.

Software for managing the attack surfaces of networks enables threat intelligence teams to see possible dangers presented by spiteful actors. They can use it to track activity linked to suspect IP addresses and spot any patterns in the behavior of online criminals.

Advantages of attack surface management

  1. Enhanced Visibility

The software gives managers greater insight into a company's network so they can quickly spot emerging dangers. Additionally, it enables them to assess the success of any adjustments they have made or intend to make to defend the system better against malevolent players.

  1. Streamlined Auditing & Reports

Attack surface management tools streamline the auditing process, which calls for gathering, organizing, and analyzing a sizable quantity of data in order to evaluate a company's security stance. Additionally, they produce tailored reports outlining any problems identified during the assessment process that must be fixed to enhance safety practices.

  1. Enhanced Safety Posture

ASM software helps companies better comprehend their recent security posture and spot scopes for development by thoroughly studying current risks and weaknesses.

  1. Risk Reduction

By locating and minimizing attack surfaces, ASM software lowers the dangers of cyber security. In order to assist companies in taking immediate action against problems before they can be abused, the system also offers a framework for tracking potential susceptibilities.
