I faced with serious problem when I try to protect Oracle database in Network DLP.
I configured datamatch registration of oracle db on Discover NDLP. In database there are only phone numbers, email addresses and users' names.
For every table of db I created separate scan operation.
In filter I filled all necessary elements
All scan operations were completed successfuly.
I configured protection rule to detect any attempts of sending data from DB via smtp.
But in incidents there are too many false positive events appeares. it seems that protection rule detect a part of cell (part of record), not all record i a cell.
For example it detect a part of email address (@gmail.com), or detect part of pnone nuber (-179)
How to configure rules to detect complete records from the cell in DB?
