Ensure 'credentials' are not stored in configuration files

BajaNivel 2Automatizadaiis

Descripción

The <credentials> element of the <authentication> element allows optional definitions of name and password for IIS Manager User accounts within the configuration file. Forms based authentication also uses these elements to define the users. IIS Manager Users can use the administration interface to connect to sites and applications in which they've been granted authorization. Note ... No forms credentials <user> entries may be stored in the root web.config or any site configuration. PowerShell 5.1 with the WebAdministration module; run elevated.
