As organizations increasingly embrace digital transformation, their attack surfaces are expanding. In this environment, Attack Surface Management (EASM) has emerged as a crucial strategy for maintaining robust cybersecurity defenses.
External Attack Surface Management (EASM) refers to the continuous identification, analysis, assessment, and monitoring of an organization's digital assets for potential vulnerabilities and attack vectors. The goal of EASM is to reduce the number of exploitable entry points that malicious actors could use to breach a network.
With cyber threats evolving rapidly, EASM provides a proactive approach to understanding and mitigating risks. This involves evaluating all assets connected to the network from the perspective of a hacker, thereby identifying potential weaknesses before they can be exploited.
Attack Surface vs. Vulnerability Management: What’s the Difference?
While both Attack Surface Management and Vulnerability Management aim to enhance cybersecurity, they approach the problem from different angles.
- Attack Surface Management offers a holistic view of an organization’s entire digital environment. It encompasses all assets, including those that might be overlooked by traditional security measures. ASM identifies not just vulnerabilities but also the connections between assets and potential attack vectors.
- Vulnerability Management, on the other hand, is typically focused on specific known assets and their vulnerabilities. It often involves scanning for vulnerabilities in software and hardware, but may not address the broader context of how these vulnerabilities interact with the organization’s entire network.
Both strategies are complementary. While Vulnerability Management addresses known issues within specific assets, ASM provides a broader view of potential vulnerabilities and attack vectors across the entire network.
Modern Challenges in Vulnerability Management
As cyber threats evolve, ASM must adapt to new challenges. Some of the modern issues include:
- Cloud Migration: The cloud provides more flexibility, cost efficiency, and scalability, but also unknowns that traditional tools can’t identify.
- Digital Transformation: Organizations are digitizing more of their services to improve customer experience and improve operational efficiency. Rapid deployments of new internet-facing infrastructure are difficult to manage with vulnerability management.
- Shadow IT: Unapproved applications and devices used within organizations can introduce additional vulnerabilities. Vulnerability management is unable to identify these shadow IT assets.
- Remote Work: The rise of remote and hybrid work has led to decentralized security practices, making it harder to manage and monitor assets.
- Alert Fatigue: With an increasing number of alerts, security teams can experience fatigue. Traditional vulnerability management tools produce large numbers of false positives and fail to prioritize relevant threats.
The Growing Importance of ASM
The expansion of digital assets due to factors like cloud adoption, Internet of Things (IoT) devices, and remote work has broadened organizational attack surfaces significantly. According to recent research, 67% of organizations have seen their attack surfaces grow in the past year alone.
This expansion means that traditional security measures might not be enough. ASM helps address this challenge by continuously scanning and managing both known and unknown assets. It ensures that organizations can detect and address potential threats in real time, minimizing the risk of successful cyberattacks.
Key Features of Attack Surface Management
Effective Attack Surface Management relies on several key features:
- Continuous Scanning: Identifying and mapping all digital assets, including unknown or overlooked ones, is the first step. Continuous scanning ensures that the organization’s attack surface is always up-to-date.
- Real-Time Testing: Regular testing and monitoring are crucial for detecting changes and new vulnerabilities. Real-time updates help security teams respond promptly to emerging threats.
- Contextual Understanding: Assessing risks in relation to other assets and organizational objectives helps prioritize threats. Not all vulnerabilities pose the same level of risk.
- Risk Prioritization: Effective ASM strategies categorize and score vulnerabilities based on their severity and potential impact. This prioritization helps focus resources on the most critical threats.
- Remediation: Beyond identifying threats, ASM also involves taking action to address them. This can include patching software, configuring firewalls, and removing obsolete assets.
Choosing the Right ASM Platform
Selecting an Attack Surface Management platform requires careful consideration. Look for features such as:
- Artificial Intelligence: AI can help prioritize risks and automate responses, reducing the manual burden on security teams.
- Agentless Platforms: These platforms provide comprehensive coverage without requiring extensive installation or management.
- Contextualization: Tools that offer a hacker’s perspective and contextualize vulnerabilities will provide more actionable insights.
The Role of External Attack Surface Management (EASM)
EASM and Its Benefits
External Attack Surface Management (EASM) focused on identifying and managing internet-facing assets. This includes domains, IoT devices, SSL certificates, and more. EASM is particularly valuable for understanding vulnerabilities that could be exploited by attackers from outside the organization.
