The method of claim 1, wherein scanning the captured email includes scanning the captured email for search terms defining personal or confidential information that are stored in a lexicon, the lexicon having one or more categories each associated with a different class of personal or confidential information.
16. The method of claim 1 wherein the one or more trends relate to identification of a specific type of information that has been located when scanning, or individuals, context or types of communications associated with one or more of the occurrences.
17. A method of analyzing email, comprising:
identifying a copy of an email transferred over a network;
encrypting the copy of the email;
transferring the encrypted copied email to a data analyzer;
decrypting the encrypted copied email;
analyzing the copied email including:
scanning the copied email for search terms defining personal or confidential information, and
identifying trends based on the personal or confidential information contained in the copied email including, after the scanning, evaluating occurrences in the copied email of the personal or confidential information and determining the nature and amount of personal or confidential information passing through the copied email; and
identifying, based on the identified trends, one or more security-related protocols for securing future communications between the sender and the intended recipient wherein the one or more security-related protocols are different than protocols used to send communications between the sender and the recipient that were included in the captured email.
18. The method of claim 17, wherein scanning the copied email includes scanning the captured email for search terms defining personal or confidential information that are stored in a lexicon, the lexicon having one or more categories each associated with a different class of personal or confidential information.
19. The method of claim 17 wherein the one or more trends relate to identification of a specific type of information that has been located when scanning, or individuals, context or types of communications associated with one or more of the occurrences.
20. A method comprising:
receiving a plurality of messages transmitted over a network, each message being communicated between a sender and an intended recipient;
analyzing the messages to identify personal or confidential information contained in the messages including evaluating occurrences of the personal or confidential information and determining the nature and amount of personal or confidential information passing through one or more of the messages;
identifying a security protocol based on the analysis; and
securing future messages as between the sender and the intended recipient using the identified security protocol wherein the security-related protocol is different than a protocol used to send the message between the sender and the recipient.
21. The method of claim 20, wherein identifying a security protocol includes identifying an encryption protocol for encrypting the message.
22. The method of claim 21, wherein securing the message includes encrypting the message based on the encryption protocol prior to delivering the message.
23. The method of claim 20 wherein the nature relates to identification of a specific type of information that has been located based on the analysis, or individuals, context or types of communications associated with one or more of the occurrences in the messages.
