Understanding Attack Surface Management (ASM)

Sep 12, 2023

red-team-white-team-2One of the latest terms to emerge in the realm of cybersecurity is ASM, which stands for Attack Surface Management. This proactive approach helps organizations identify, monitor, and mitigate potential attack vectors within their systems. ASM has become an essential practice for organizations aiming to protect their valuable assets. In this article, we will delve into the essentials of ASM, discuss the key factors to consider for effective implementation, and highlight how PathSolutions can address these requirements.

Understanding ASM

Attack Surface Management refers to the process of assessing and managing an organization's exposure to potential cyber threats. It involves identifying and analyzing all possible entry points, vulnerabilities, and assets within an organization's network, applications, systems, and infrastructure. By gaining a comprehensive understanding of their attack surface, organizations can prioritize their security efforts and allocate resources effectively.

Factors for Effective ASM

  1. Asset Discovery:  The first step in ASM is to identify and catalog all assets, including hardware, software, and data, across an organization's infrastructure. This comprehensive asset inventory forms the foundation of effective ASM.

  2. Vulnerability Assessment: Conducting regular vulnerability assessments is crucial to identify weaknesses and potential entry points within an organization's systems. This assessment helps prioritize security measures and allocate resources where they are most needed.

  3. Continuous Monitoring: ASM is an ongoing process that requires continuous monitoring of an organization's attack surface. By constantly monitoring for new vulnerabilities, misconfigurations, or changes within the environment, organizations can promptly address potential risks and enhance their security posture.

  4. Risk Prioritization: Not all vulnerabilities are created equal. ASM involves assessing the risk associated with each vulnerability and prioritizing their remediation based on the potential impact on the organization's security. Risk-based prioritization ensures that limited resources are used efficiently.

How TotalView Addresses ASM Requirements

PathSolutions TotalView® Security Operations Manager addresses the key requirements for effective ASM. Here's how this tool can help organizations enhance their security posture:

  1. Complete Asset Discovery: TotalView Security Operations Manager employs advanced scanning techniques to discover and catalog all assets across an organization's infrastructure. This is called new device discovery and it includes finding any IoT devices and Rogue IT. This enables organizations to gain a holistic view of your attack surface.

  2. Continuous Vulnerability Assessment:  It conducts continuous and comprehensive vulnerability assessments, providing organizations with real-time insights into your security weaknesses and NetFlows. By the way, v14 also now monitors all your SSL certs and DNS records, in addition to standard hardware. By identifying vulnerabilities as they emerge, organizations can proactively address them before threat actors can exploit them.

  3. Automated Risk Prioritization: It utilizes intelligent risk-scoring mechanisms to prioritize vulnerabilities based on their potential impact. This enables organizations to efficiently allocate resources to remediate high-risk vulnerabilities first, reducing their overall risk exposure.

  4. Actionable Insights and Reporting: It provides detailed and actionable reports, such as the Nightly Security Report,  that highlight vulnerabilities, misconfigurations, and potential attack vectors. These insights empower organizations to make informed decisions and take proactive steps to improve their security posture.

  5. Validation: Once remediated, the TotalView SecOps Manager can show the day-to-day improvement of the organization via the nightly security reports.

By understanding your attack surface, implementing effective ASM strategies, and leveraging solutions like the TotalView Security Operations Manager, you can proactively mitigate risks and enhance your organization’s overall security posture, to identify, prioritize, and address vulnerabilities.
