RSA Email DLP Fails to Detect Violations in Email Attachments
Problem When using predefined DLP policies, RSA Email DLP fails to detect violations in email
attachments. This can be caused by the small value of the proximity parameter in the predefined DLP
policies.
Note You cannot change the proximity of a predefined DLP policy.
Solution Do one of the following:
• Create a custom policy and adjust the proximity as required. See Creating a Custom DLP Policy
(Advanced), page 17-9.
• Use RSA Enterprise Manager and the predefined policies in it. RSA Enterprise Manager allows you
to fine-tune the predefined policy configurations such as proximity. See RSA Enterprise Manager,
page 17-23.
