5 Best Attack Surface Management Vendors

An attack surface management platform is a software solution designed to help organizations identify, inventory, classify, prioritize, threat detection and vulnerability management, monitor network changes, and prevent unintentional exposure of external digital assets that could be vulnerable to cyber threats. By continuously analyzing and scanning an organization’s attack surface, these tools help to reduce the risk of breaches and ensure that the organization’s security posture remains strong.

The primary functions of an Attack Surface Monitoring tool include:

Discovery: ASM tools automatically discover and catalog an organization’s external digital assets. This includes web applications, domains, subdomains, IP addresses, cloud infrastructure, Internet of Things (IoT) devices, and other connected systems that may be exposed to potential threats.

Inventory: After discovering external assets, ASM tools create an inventory, providing a comprehensive overview of an organization’s digital footprint. This inventory helps security teams identify and manage potential risk areas.

Classification: ASM tools classify discovered assets based on various criteria, such as their criticality, sensitivity, and potential impact on the organization if compromised. This classification helps security teams prioritize their efforts and allocate resources more effectively.

Prioritization: Based on the classification, ASM tools prioritize assets that require immediate attention, helping security teams focus on high-risk areas and address vulnerabilities before they can be exploited by attackers.

Security Monitoring: ASM tools continuously monitor the organization’s attack surface for potential threats and vulnerabilities. They may integrate with other security solutions, such as vulnerability scanners and threat intelligence platforms, to provide real-time analysis and alerts on emerging risks.

And, what is Attack surface analysis and how does it work?

Attack surface analysis is a critical component of an organization’s cybersecurity strategy. By systematically evaluating an organization’s digital assets, identifying potential threats and vulnerabilities, and implementing appropriate mitigation measures, security teams can reduce the likelihood of successful cyber attacks and minimize the potential impact of breaches.

Attack surface analysis is a systematic process of identifying, evaluating, and understanding the various entry points, vulnerabilities, and weaknesses that an attacker could exploit to compromise an organization’s digital assets. The primary goal of attack surface analysis is to reduce the organization’s exposure to cyber threats and improve its overall security posture.

The Attack surface analysis process typically involves the following steps:

  1. Asset Identification: The first step in attack surface analysis is to identify all digital assets associated with the organization. This includes servers, databases, web applications, network devices, cloud infrastructure, mobile devices, IoT devices, and any other connected systems.
  2. Mapping: After identifying the assets, they are mapped to visualize the organization’s attack surface. This can help security teams understand the relationships and dependencies between assets, as well as identify potential weak points in the infrastructure.
  3. Threat Modeling: Security teams analyze the attack surface to identify potential threats and threat actors that could target the organization. This includes assessing the likelihood of various attack vectors, as well as the potential impact on the organization if an attack were to occur.
  4. Vulnerability Assessment: Next, security teams scan the identified assets for known vulnerabilities using vulnerability scanners and other security tools. This helps in uncovering weaknesses and security flaws that could be exploited by attackers.
  5. Risk Analysis: After identifying threats and vulnerabilities, security teams perform a risk analysis to prioritize assets and vulnerabilities based on their potential impact on the organization. This helps in determining which issues need immediate attention and allows for more effective allocation of resources.
  6. Mitigation Strategies: Based on the risk analysis, security teams develop and implement mitigation strategies to address the identified vulnerabilities and reduce the attack surface. This can involve patching vulnerable software, implementing security controls, hardening systems, and conducting employee training on security best practices.
  7. Continuous Monitoring: As the organization’s attack surface evolves over time, continuous monitoring is essential to maintain an up-to-date understanding of potential risks. Security teams should regularly review and update their analysis, ensuring that new assets are accounted for and emerging threats are addressed promptly.
