A network connection between a server group of a data intake and query system and each of one or more source network nodes is established. The server group includes an indexer server and a model management server. Source data at the server group is received from at least one of the one or more source network nodes. A model management server detects data constraints for a security model. The data constraints include a data element used by the security model and an availability requirement set. Using the timestamped entries, the data constraints are validated to obtain a validation result. The model management server determines a data availability assessment of the security model based on the validation result. The data availability assessment of the security model is stored in computer storage.
