Scope of the scan

If we are required to perform a vulnerability assessment for a specific application's infrastructure, it is very important to identify the data transmission sources and the components involved in the end-to-end communication. This will allow the penetration tester to perform the vulnerability scan on this scope and identify vulnerabilities specific to this application. Instead, if we choose to scan the subnets or a broader range of IP addresses, we might end up highlighting unnecessary vulnerabilities, which most of the time leads to confusion during the remediation phase. For example, if we are looking to audit a web-based application, we might be looking to include a web application, application server, web server, and database server as part of the audit scope.
