Attack Surface Management

Attack surface refers to all the points in a system where an unauthorized user could attempt to enter or extract data. It includes network infrastructure, applications, storage, IoT devices, and cloud services. Understanding your attack surface helps minimize security risks by identifying and addressing exposure points.

Attack surface management (ASM) is a proactive approach to identify, assess, and reduce vulnerabilities in an organization's digital infrastructure. It involves discovering potential threats, prioritizing and mitigating them, and continuously monitoring for new risks to strengthen overall security.

Core components of ASM include asset discovery, vulnerability assessment, risk evaluation, threat intelligence, configuration management, and incident response planning. These elements work together to reduce an organization's exposure to cyber threats.

ASM helps reduce the risk of cyberattacks, improves regulatory compliance, enhances your organization's reputation, and leads to cost savings by preventing breaches and downtime through proactive vulnerability management.

Challenges include the complexity of modern IT systems, limited resources, the constantly evolving threat landscape, and false positives in vulnerability scans. These can make ASM implementation and upkeep resource-intensive.

To improve ASM, organizations should prioritize high-risk vulnerabilities, automate detection and assessment processes, integrate ASM with other security tools, train personnel, and continuously review and update the attack surface data.

ASM relies on tools such as asset discovery solutions, vulnerability scanners, configuration management platforms, threat intelligence services, and incident response tools. These tools provide automation, insight, and management capabilities.

ImmuniWeb® offers an end-to-end ASM solution including automated discovery, vulnerability testing, dark web monitoring, and continuous reporting. It enables you to uncover unknown assets, assess risk, and maintain a proactive security posture.

Key benefits include full asset visibility, prioritization of critical risks, reduced manual effort via automation, real-time monitoring of threats, and compliance support. ImmuniWeb® also integrates with existing tools and provides fixed pricing.

ImmuniWeb® ASM uses your company name to discover external assets across on-premise and cloud environments. It identifies outdated software, shadow IT, misconfigurations, and dark web leaks, while providing dashboards, alerts, and exportable reports for ongoing management.
