The 'security' verb of systemd-analyze needs to be able to parse JSON files to be able to read in the user-defined requirements and use them to determine the overall exposure level of the specified unit file(s). The JSON files are expected to have a specific format where the keys in the file are the unit ids consisting of only alphanumeric characters and underscores and the values are JSON objects again consisting of key value pairs. The keys in these objects may include one or more of the following properties: description_na, description_good, description_bad, weight, and range. The first three of these are expected to be strings and the latter two are expected to be unsigned integer values. If one or more of these properties is missing from the JSON object, then the default values of the properties as specified in the hard coded set of security directives is used. The other properties that assess() needs to determine overall exposure levels for a unit file for example, the assess function and parameter type among others, are not to be included in the JSON files defined by the user because the values assigned to these fields are expected to be consistent across unit files for each id.
