What Is Attack Surface?
The total set of points where an attacker can try to enter or extract data from a system. This includes every API endpoint, open port, login form, file upload, third-party integration, and piece of infrastructure reachable from the outside.
In Laravel Applications
In a Laravel application, the attack surface includes all registered routes, exposed debug tools (Telescope, Ignition, Horizon), .env files, storage directories, DNS records, security headers, and open ports on the server.
Example
A Laravel app with 50 routes, an exposed Telescope dashboard, and an open Redis port has a larger attack surface than one with 50 routes, Telescope disabled, and Redis firewalled.

Attack Vector
A specific method or path an attacker uses to exploit a vulnerability and gain unauthorized access to a system. While the attack surface is the total collection of entry points, an attack vector is the specific technique used against one of those entry points.
External Attack Surface Management (EASM)
The continuous process of discovering, monitoring, and managing all internet-facing assets and their security posture from an external perspective. EASM tools scan your applications the way an attacker would, identifying exposed services, misconfigurations, and vulnerabilities visible from the outside.
Vulnerability
A weakness in a system that can be exploited by an attacker to perform unauthorized actions. Vulnerabilities can exist in code, configuration, infrastructure, or processes. They range in severity from informational to critical.
