Since mail is a key tool in your customer service resources, Exchange 2013 offers tools to help you prevent, detect, and respond to important business information in email. Knowing that an attachment is compressed or has embedded files can help you avoid on the fly inspection. The "Match conditions" task pane on the contact management page in the Mail Flow or transport rules settings provides a list of conditions you can choose to inspect email. The "Properties" task pane in Mail Flow or transport rules settings shows information about the attachments, such as file size and file type, that aren't included in the conditions. For example, you can't count on including a specific file type in transport conditions, so you might prioritize data inspection based on file type. You can also, in Exchange 2013, count on using policies to protect important data without adding an Exchange specific data protection technology.
For a business that has sensitive information that it wants to protect, you can build attachments-related rules using the "Email Scan Mail rules" task pane and the "Email Enhanced Scan Mail rules" task pane. In large organizations, you can start by adding standard DLP rules, such as scan mail that has sensitive data, scan mail containing specific file types, and scan mail matching a regular expression. For details, see Scan and review.
You can also protect sensitive information such as passport numbers in your organization with policies that attach to messages. You can create policies that only attach to specific sizes of files. You can also keep the attachment ready for inspection as you initiate the transport rules flow. You could for example have policies attached to messages with password-protected attachments only if they're encrypted or ZIP files. In fact, a policy that comprises several attachments might need to be attached to a message as a prerequisite to the transport rules that follow.
Email is a key tool for a growing number of business processes. As a result, protecting important business information is getting more complex. You can take steps by using existing Exchange 2013 tools. d2c66b5586
