Overview
EASM Scenario
🌐 What is External Attack Surface Management (EASM)?
EASM is a cybersecurity practice focused on discovering, mapping, and continuously monitoring all internet-facing assets of an organization (websites, IP addresses, cloud services, APIs, admin portals, etc.). 👉 The goal is to take the attacker’s perspective in order to identify vulnerabilities, misconfigurations, or forgotten services before they can be exploited.
Key challenges it addresses:
🔎 Eliminating blind spots (shadow IT, unmanaged services)
⚠️ Detecting vulnerabilities (CVEs) and risky configurations early
🛡️ Maintaining a strong security posture in a constantly evolving IT environment
⚙️ How OpenBAS solves this challenge
With OpenBAS, an EASM scenario can be set up in a fully agentless way (no installation required):
🆔 Simply define an asset using an IP address or FQDN.
🧭 OpenBAS then performs enumeration just like an attacker would:
Identifying open ports and running services
Detecting exposed administration portals
Checking for known vulnerabilities (CVEs)
Highlighting misconfigurations (e.g., default credentials)
📊 Findings are correlated and reported, giving clear visibility into external exposure.
⏰ By scheduling this scenario daily, organizations ensure their scope remains secure over time.
👉 In short, combining EASM + OpenBAS enables: ✅ Thinking like an attacker ✅ Continuously monitoring external exposure ✅ Validating the security of the perimeter day after day 🚀
