Vulnerability Management: Part 3 – Attack Surface Management

Combine threat and attack surface intelligence to experience true resolution intel

Welcome back to the final part of our series on vulnerability management on attack surface management. In case you are new here, you should quickly browse through the first two installments:

Risk-based Vulnerability Management for Attack Surface Reduction

Organizations nowadays need to combine risk-based vulnerability management with attack surface reduction. Risk-based vulnerability management involves a constant cycle of identifying, classifying, prioritizing, remediating, and mitigating exposed software vulnerabilities. On the other hand, the latter aims to reduce the number of exposed open ports and services. The idea here is to reduce vulnerabilities and limit the ability of malicious actors to perform attacks. Attack surface management combines these two principles to build one comprehensive system.

What is Attack Surface Management?

Attack surface management (ASM) is the continuous discovery, inventory, classification, prioritization, and security monitoring of external assets that contain and transmit sensitive data. Smart and efficient ASM dramatically reduces the risks of data breaches and leaks.

ASM allows you to prevent damage originating from:

  • Vendor managed assets
  • Legacy, IoT, and shadow IT assets
  • Networks and systems inherited during mergers and acquisitions
  • Open-source software
  • Cyberattacks on your organization

Netenrich’s Attack Surface Intelligence (ASI) leverages security experts and artificial intelligence (AI) to provide actionable insight into your company’s external digital risk. Here’s how the process works:

  • Machines perform external assessments to discover risks related to domains, IPs, digital brand exposure, certificates, misconfigurations, and vulnerabilities
  • Alerts collected across the disparate data sources in your systems are provided on one screen in Netenrich’s threat intel dashboard
  • Netenrich’s security analysts provide impact analysis and recommend remediation strategies to resolve your most critical risks

The process consists of four critical steps:

#1 Discovery

ASI’s scanning engines scour through billions of data points and identifies associated digital assets and shadow IT related to your brand. The engines are designed to dig deep into areas that generally take significant time to research, associate, and assess. It can do all this with a single seed of data, like an email address or domain name. Potential risk points are collated on a single dashboard for rapid consumption and investigation.

#2 Analysis

Following discovery, the next step is analysis beginning with an extensive automated evaluation that correlates data, identifies false positives, and performs risk-checks to assess your overall attack surface status. During this process, data is correlated and validated against our proprietary threat intelligence.

#3 Prioritization

During this step, Netenrich’s cybersecurity analysts vet findings to validate machine-generated recommendations.

#4 Remediation

The final phase is analyst-led threat impact analysis and recommendations. In this phase, you will receive actionable reports that contain affected assets, technical details, context, and technical remediation advice.

Benefits of Attack Surface Intelligence

Complementing solutions like pen testing that examine your attack surface at one point in time, ASI provides ongoing discovery to steadily reduce your attack surface over time. Benefits include:

  • Empowering your SOC team to prevent attacks proactively
  • Stronger overall security posture
  • Reducing skill gaps in your organization

Combining Threat and Attack Surface Intelligence

Netenrich’s Resolution Intelligence is a powerful combination of machine and human intelligence. ASI is also integrated with Netenrich’s proprietary threat intelligence from our Knowledge NOW (KNOW) platform. Use KNOW and ASI to shrink your attack surface, manage your threat landscape, uplevel your SecOps with ease, and protect your digital brand at all times.

Netenrich analyzes millions of signals across the Internet so you can discover newly exploited vulnerabilities and track changes in risk status for third-party applications in your stack. Want to know more about how this works?

Yes, I do!
