Cybercriminals exploit vulnerabilities and misconfigurations across an organization’s attack surface to gain unauthorized access to sensitive data. 

The prevalence of digital transformation and outsourcing in the current threat landscape means an organization’s attack vectors can easily increase by millions each day. This ever-growing number makes it hard to identify cyber threats and prioritize remediation before a data breach occurs.

Automated attack surface management software helps security teams stay on top of both an organization and its vendors in a centralized platform that can monitor and manage vulnerabilities and misconfigurations as they appear. 

With many solutions offering attack surface management capabilities, you may need help choosing the best solution for your organization’s needs. 

This guide outlines the main considerations of effective attack surface management software and the best solutions currently on the market.

What is Attack Surface Management Software?

Attack surface management (ASM) software is a set of automated tools that monitor and manage external digital assets that contain, transmit, or process sensitive data. ASM software identifies misconfigurations and vulnerabilities that cybercriminals could exploit for malicious purposes that result in data breaches or other serious security incidents.

Who Uses Attack Surface Management Software?

Any organization that deals with sensitive data should monitor and manage its attack surface vigilantly. Data security standards are mandated by privacy and protection laws, such as the GDPR, CCPA, and SHIELD Act. Organizations that suffer data breaches face non-compliance with these legal requirements. Harsh financial penalties and reputational damage follow shortly after.

Small businesses and large multinational organizations from all industries can benefit from attack surface management software. Fast remediation is essential in industries with large amounts of confidential data. These types of data could include personally identifiable information (PII), trade secrets, intellectual property, or other confidential information. 

For example:

  • The healthcare sector manages protected health information (PHI). This data is highly valued on the dark web, with cybercriminals purchasing it to commit identity theft and insurance fraud. 

Read about recent data breaches in the healthcare industry.

  • Financial institutions must protect sensitive information, such as credit card numbers and bank account details. Financial data is also very profitable in cybercrime. Cybercriminals can exploit it instantly for theft.

Read about recent data breaches in the financial industry.

  • Government bodies hold in-depth PII on citizens, protected records, and other highly classified information. Threat actors with political motivations, such as ransomware gangs, are likely to target government organizations in cyber attacks.

Important Features of Attack Surface Management Software

Modern attack surface management software must offer the following five features to perform its role effectively:

  • Step 1: Asset Discovery
  • Step 2: Inventory and classification
  • Step 3: Risk scoring and security ratings
  • Step 4: Continuous security monitoring
  • Step 5: Malicious asset and incident monitoring

1. Asset Discovery

The initial stage of any reputable attack surface management solution is the discovery of all Internet-facing digital assets that contain or process your sensitive data such as PII, PHI, and trade secrets. 

These assets can be owned or operated by your organization, as well as third parties such as cloud providers, IaaS and SaaS, business partners, suppliers, or external contractors. 

2. Inventory and Classification

Following asset discovery, the digital asset inventory and classification (IT asset inventory) process begins.

During this step, assets are labeled and dispatched based on:

  • Type;
  • Technical characteristics and properties;
  • Business criticality;
  • Compliance requirements;
  • Owner

3. Security Ratings and Risk Scoring

Security ratings and risk scoring quickly identify the security issues affecting each asset and whether they are exposing information that could result in data breaches, data leaks, or other cyber attacks

4. Continuous Security Monitoring

Continuous security monitoring is one of the most important features of an attack management solution. Sophisticated cyber attack techniques emerge daily and zero-day vulnerabilities pose a bigger threat the longer they go undiscovered and unpatched. Effective attack surface management software will monitor your assets 24/7 for newly discovered security vulnerabilities, weaknesses, misconfiguration, and compliance issues. 

Learn more about continuous security monitoring.

5. Malicious Asset and Incident Monitoring

The modern threat landscape is infamous for malicious or rogue assets deployed by cybercriminals. These cyber attacks expose sensitive data, which remains visible on the Internet long after its initial compromise. Left exposed, this data could be further exploited in a future attack. 

A complete attack surface management solution scans the surface, deep, and dark web for known third-party data breaches to identify any leaked employee credentials before they are used to gain unauthorized access to your organization.
