Attack Surface Management
The continuous process of discovering, inventorying, and reducing exploitable entry points across an environment. Effective attack surface management requires complete, real-time asset visibility.
What is Attack Surface Management?
The continuous process of discovering, inventorying, and reducing exploitable entry points across an environment. Effective attack surface management requires complete, real-time asset visibility.
Attack surface management (ASM) is the continuous process of discovering, inventorying, and reducing the exploitable entry points across an organization's entire digital environment. The "attack surface" is the totality of paths through which an attacker could gain unauthorized access — every network-connected device, every open port, every public-facing application, every credential, every unpatched vulnerability, every misconfiguration.
The emphasis on "continuous" is important. Attack surfaces are not static. New devices are connected, new vulnerabilities are published, configurations change, cloud resources are provisioned, and external attack surface shifts as applications and services are added or modified. A point-in-time assessment of the attack surface is useful for a moment; continuous monitoring keeps the picture current.
In IoT and OT environments, attack surface management faces unique challenges. Traditional ASM tools focus on internet-facing assets — what an external attacker can see from the internet. Internal IoT, OT, and IoMT devices are largely invisible to external ASM tools, yet they represent significant internal attack surface: devices that an attacker who has achieved any initial access can pivot to and potentially exploit. Internal attack surface management requires comprehensive network monitoring, not just external scanning.
Key Facts
- The average enterprise adds 7–10 new network-connected devices per day — attack surface grows continuously
- Internal IoT and OT devices represent over 50% of the exploitable attack surface in healthcare and manufacturing
- CISA's Continuous Diagnostics and Mitigation (CDM) program mandates ongoing attack surface monitoring for federal agencies
- Reducing the attack surface is consistently ranked among the highest-impact, lowest-cost security controls
How ORDR Addresses Attack Surface Management
ORDR extends attack surface management to the internal connected device estate — discovering every IoT, OT, and IoMT asset, scoring its exploitability based on CVE data, KEV status, EPSS, and network exposure, and tracking changes as the environment evolves. This gives security teams a continuous view of their full internal attack surface, not just the perimeter.
