Confidentiality ensures that only authorized persons can see specified information.
Unlike the cases described in the previous section, information security enables organizations to maintain trade secrets. Control determines who is authorized to access and possess information. For example, a software vendor may want to control who can access the software it is attempting to sell over the Internet so it can maintain profit margins. Authenticity means that corporate and individual identities can be confirmed that the information provided has not been tampered with. Availability ensures that information can be accessed over the Internet.
