What Are the Key Features To Look For in Attack Surface Management Software?

The right attack surface management (ASM) software depends on your organization’s unique technology stack and monitoring needs. Below are essential features to consider when choosing an ASM solution to ensure it meets your specific requirements.

• Comprehensive Asset Discovery: The ASM software should discover all assets, including subdomains, APIs, and shadow IT, across on-premises, cloud, and hybrid environments.
• Continuous Security Monitoring: An ASM solution should offer real-time attack surface monitoring to detect vulnerabilities and misconfigurations as soon as they surface.
• Risk Scoring and Security Grading: The ASM tool should assess all identified assets for vulnerabilities and misconfigurations, providing scores based on the Common Vulnerability Scoring System (CVSS) or similar metrics. This will enable you to prioritize vulnerability remediation efforts effectively. An overall security grade reflecting your security posture will help you understand your progress in reducing the attack surface.
• Integration Capabilities: The ASM tool you are considering must integrate seamlessly with your existing security solutions, such as SIEM, SOAR, or XDR.
• Threat Intelligence Integration: Threat intelligence integration provides contextual awareness of emerging threats, enabling proactive vulnerability identification and improving alert prioritization for faster, more effective responses.
• Automated Alerts: It should provide instant alerts when your attack surface changes, enabling your security team to act proactively.
• Detailed Reporting: The ASM software should provide detailed reports with insights into your attack surface and vulnerability trends, helping you make informed decisions and meet compliance requirements like GDPR, PCI DSS, and HIPAA.

Can SIEM Software Work As an Attack Surface Management Tool?

No, SIEM software cannot work as a full-fledged attack surface management tool. The main purpose of SIEM tools is to monitor and analyze security events by collecting logs from devices on the network and analyzing those logs for anomalies. They detect security incidents and help you respond to those incidents.

On the other hand, attack surface management solutions focus on identifying and managing all possible points of cybersecurity attacks, such as exposed, vulnerable assets, misconfigurations, shadow IT, EoL, and EoS resources across your organization’s digital footprints.

Integrating SIEM and ASM solutions strengthens overall security by combining threat detection with continuous attack surface monitoring and effective attack surface management.

Can Attack Surface Management Software Identify Vulnerabilities in My Systems?

Yes, Attack Surface management (ASM) tools can identify vulnerabilities in your systems. ASM tools use automated scanning and attack surface analysis techniques based on AI and ML to uncover various vulnerabilities in your systems, such as configuration errors, open ports, unpatched software, and signs of malicious activity.

You can use web vulnerability scanners to find vulnerabilities in your web application.

Is Attack Surface Management Software Suitable for Small Businesses?

Yes, attack surface management (ASM) software is suitable for small businesses. By mapping and monitoring the entire attack surface, ASM software helps small businesses identify vulnerabilities, misconfigurations, and exposed assets, even with limited IT resources.

Hackers are increasingly targeting small businesses, for small businesses have more data than individuals and poorer security than big companies. So, they are perfect targets for hackers.

By using ASM tools, small businesses can automate threat detection, reduce manual monitoring, prioritize risk remediation, and implement suitable types of security controls to prevent attack vectors.

What Are the Key Challenges in Implementing Attack Surface Management Software?

Implementing ASM software can present several challenges, with asset discovery being the biggest. As cloud services, IoT, and interconnected systems expand, the attack surface constantly evolves, making it difficult to find a tool that can effectively map all assets.

Integration is another challenge, as your chosen ASM software may not work easily with your existing security tools. Small businesses, in particular, may struggle with limited resources and expertise to manage ASM software efficiently.

Additionally, ASM tools generate large volumes of data, making it hard to prioritize critical vulnerabilities. Though many tools offer asset risk scoring and security ratings to prioritize vulnerability remediation, human oversight is always necessary for effective risk remediation.

Given these challenges, it’s critical to assess your requirements and test multiple ASM tools to find the best solution for mapping, monitoring, and managing your attack surface.
