CSHARP.INSEC.MDSS : Method Disables Security Setting (C#)

JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

CSHARP.INSEC.MDSS : Method Disables Security Setting (C#)

要旨

A safe security setting seems disabled.

It should be avoided a mismatch of security annotations between code elements of larger scope to elements of smaller scope. The security annotations of the element with the larger scope always wins.
Certifications should not be added to the operating system's trusted root, as it can lead to accept untrusted certification authority.
It should be never acceptable to disable security protocols or not to use a strong cryptography. Anyway, this can be done by calling the method AppContext.SetSwitch() and setting Switch.System.Net.DontEnableSchUseStrongCrypto to true or by setting Switch.System.ServiceModel.DisableUsingServicePointManagerSecurityProtocols to true.
