| Metadata is information about one or more pieces of data. This may include information about the data's purpose, creator, origin, or classification. Information flow control regulates where information is allowed to travel within a network and between hosts as opposed to who is allowed to access the information. Information flow enforcement mechanisms compare security attributes on all information such as source and destination objects, and respond appropriately (e.g., block, quarantine, alert administrator) when the mechanisms encounter information flows not explicitly allowed by the information flow policy. This is a network architecture best practice and does not require a configuration setting on the IDPS sensor. |
