In the midst of security planning and deploying security solution, many clients opt to disable weak protocols as there step to ensure security in their cloud systems.

This is done to perform the desired registry changes on a Windows Server. This makes the admins perform the necessary steps to disable SSL 3 on the server host.

Issues on previous builds

Previous MachPanel builds didn’t allow admins to disable SSLv3 directly since they stopped admins from gaining access via API. In that case, there was a error displayed, once the admin clicks on “Login to control panel” from WHMCS to login directly to MachPanel. The error and its details are:

Error: “Operation failed.Error in fetching tenant details from office 365.

Details: Error processing command: System.Management.Automation.RemoteException: Authentication Error: Unable to complete authentication request (potentially a proxy issue)

In such a case the error would only go away if you would SSL 3 back ON.

The Solution

In the modern builds of MachPanel, this feature to disable SSL 3 is fully supported. Now, you can disable weak protocols are hashes with all other MachPanel services running intact.

If SSL v3 is disabled, the following command needs to be run before Connect-MsolService command:

[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12;

This fixes the previously occurring error message in the latest MachPanel build. More details on the solution can be found here.

With this solution, a good combination of efficiency and cloud security is achieved and the cloud systems can be protected from increasing vulnerabilities in the cyberspace.
