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 security 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. The vulnerability severity measuring aspect of ASM functionality could also support penetration testing efforts and related risk management dependencies.

Who uses attack surface management platforms?

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 leveraging service providers 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. The vulnerability scanning features of attack surface management tools could detect risks threatening the safety of PHI.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 are always scanning financial entities for potential vulnerabilities to exploit.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 tools

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

For a concise overview of the attack surface reduction process, watch the video below.

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. The collection of these assets make up your digital footprint.

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. The presence of Shadow IT - digital devices that haven’t been approved by security teams, makes the inventory stage of asset management very difficult.

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 offer an objective and unbiased evaluation of a vendor’s security posture. According to Gartner, this feature will become as important as credit ratings when assessing the risk of existing and new business relationships in a Vendor Risk Management program.

4. Continuous security monitoring

Continuous security monitoring is one of the most important features of an attack management solution, as it ensures the timely detection and remediation of emerging vulnerabilities in your digital footprint. 

5. Integrated Risk Management Workflows

An ideal ASM tool should include integrated workflows addressing the complete risk treatment lifecycle. These should include:

  • Remediation workflows: For instantly assigning risk treatment responses for detected exposures across internal and external attack surfaces.
  • Risk assessment workflows: For in-depth evaluations of third-party vendors impacted by threats in the external attack surface.
  • Reporting workflows: For keeping stakeholders informed of your internal and external attack surface management efforts.
