In this post, we will see and learn about the Disallow Digest Authentication Using Intune. We will apply Disallow Digest Authentication Policy Using Intune. We will make use of Configuration Profiles from Intune to implement this policy.
Disallow Digest Authentication Policy is a security configuration setting that can be enforced using Microsoft Intune, a cloud-based endpoint management solution. It helps protect your organization’s resources by preventing the use of Digest Authentication for accessing various services and applications.
Digest Authentication is a method used for authentication in web-based applications. It involves the exchange of a hashed password between the client and the server, which provides a level of security. However, Digest Authentication has certain vulnerabilities that make it less secure compared to other authentication methods like Kerberos or NTLM.
By enforcing the Disallow Digest Authentication policy using Intune, you can ensure that devices managed by Intune do not use Digest Authentication when accessing resources. This policy can be applied to various platforms, including Windows, macOS, iOS, and Android, allowing you to maintain a consistent security posture across different devices.
Intune provides granular control over policy configuration. You can choose to apply the policy to specific platforms, device groups, or individual devices, allowing you to tailor the policy enforcement based on your organization’s requirements.
