This routine is used to update and retrieve the current security settings. Security settings can only be modified when security is disabled. Changes to security settings are lost on restart.

This routine returns the current security settings (prior to the call) as an expression sequence of equations of the form name = val. Here, name is a recognized security setting name and val is, depending on the name, either a boolean or a list of file specifications.

If the settings argument is provided, each name = val pair is applied to the current settings, replacing the previous value.

Valid names are:
