Attack Surface Management (ASM) is a proactive cybersecurity approach that continuously identifies, monitors, and secures all potential entry points that could be exploited by attackers. These entry points encompass hardware, software, cloud services, APIs, domains, and more.
How ASM Reduces Risk Exposure?
-
Comprehensive Asset Discovery
ASM tools perform continuous scanning to discover all assets within an organization's digital infrastructure, including those that are unknown, unauthorized, or forgotten (often referred to as "shadow IT"). By identifying these assets, organizations can ensure that no potential entry points are overlooked.
-
Continuous Monitoring and Assessment
Unlike periodic security assessments, ASM provides ongoing monitoring of the attack surface. This continuous vigilance allows for the prompt detection of new vulnerabilities, misconfigurations, or changes in the IT environment that could introduce security risks.
-
Prioritization of Vulnerabilities
ASM helps organizations assess and prioritize vulnerabilities based on their potential impact and exploitability. This risk-based approach ensures that the most critical issues are addressed first, optimizing resource allocation and enhancing overall security posture.
-
Reduction of Attack Surface
By identifying and eliminating unnecessary or exposed assets, ASM effectively shrinks the overall attack surface. This reduction makes it more challenging for attackers to find exploitable entry points, thereby decreasing the likelihood of successful breaches.
-
Enhanced Visibility and Control
ASM provides organizations with a comprehensive view of their digital footprint, including third-party integrations and external-facing assets. This visibility is crucial for implementing effective security controls and ensuring compliance with regulatory requirements.
