Which attack-surface-management activity focuses on enumerating an organization's network perimeter and internet-facing services so that those assets can be secured and the overall attack surface reduced?
Fuzz testing
Security baseline scanning
Static code analysis
Edge discovery
Edge discovery identifies all hosts, IP ranges, domains, and services that are visible from outside the organization. By cataloging these boundary assets, security teams gain the visibility needed to patch vulnerabilities, disable unused services, and implement compensating controls-thereby directly reducing the attack surface. Security-baseline scanning, static code analysis, and fuzz testing are valuable, but they do not focus on mapping the external network edge.
