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.
