content dictionaries, DLP dictionaries, disclaimers, and templates.
content dictionaries, DLP dictionaries, disclaimers, and templates.
Content Dictionaries
You can use content dictionaries to scan messages against message or content
filters in order to take appropriate action in accordance with your corporate
policies. You can create, delete, and view dictionaries; add and delete entries from
a dictionary; and import and export entire dictionaries. You can also determine
case sensitivity and word boundary detection for each dictionary. For example,
you could create a list of confidential or profane words, and, using a filter rule to
scan messages for words in the list, drop or archive messages containing matching
words. And you can add a “weight” terms in a dictionary so that certain terms
trigger a filter action more easily.

Dictionaries can contain non-ASCII characters.
DLP Dictionaries
You can use data los prevention (DLP) dictionaries in custom DLP policies to scan
outgoing messages for sensitive information. Similar to content dictionaries, you
can create, delete, and view dictionaries; add and delete entries from a dictionary;
and import and export entire dictionaries. Unlike content dictionaries, terms in
DLP policies do not have a “weight.” AsyncOS comes with a set of predefined
dictionaries from RSA Security Inc., but you can create custom DLP dictionaries.
