Ensure 'Allow Basic Authentication prompts from network proxies' is set to 'Disabled'

TinggiLevel 1Otomatisintune-office

Deskripsi

Apps such as Word and Excel allow users to use Basic authentication to connect to resources on web servers by sending usernames and passwords with each request. These credentials are often stored on the servers, making it easier for attackers to capture them and reuse them against other endpoints or services. The recommended state for this setting is: Disabled. Note: This policy setting only applies to subscription versions of Office, such as Microsoft 365 Apps for enterprise, and to subscription versions of Project and Visio. Note 2: This change doesn’t affect Outlook connecting to on-premises Exchange Server using Basic authentication. ... Audit: reads the registry value(s) basicauthproxybehavior that the Intune policy writes for every loaded user profile (HKEY_USERS) and prints compliant only when each satisfies the benchmark value.
