Customized Keyword Lists
Create customized keyword lists if none of the predefined keyword lists meet your
requirements.
There are several criteria that you can choose from when configuring a keyword list. A
keyword list must satisfy your chosen criteria before OfficeScan subjects it to a Digital
Asset Control policy. Choose one of the following criteria for each keyword list:
TABLE 9-6. Criteria for a Keyword List
CRITERIA RULE
Any keyword A file must contain at least one keyword in the keyword list.
All keywords A file must contain all the keywords in the keyword list.
All keywords
within
characters
A file must contain all the keywords in the keyword list. In
addition, each keyword pair must be within characters of
each other.
For example, your 3 keywords are ABCDE, FGHIJ, and WXYZ
and the number of characters you specified is 20.
If OfficeScan detects all keywords in the order FGHIJ,
ABCDE, and WXYZ, the number of characters from F to A and
from A to W must be 20 characters at most.
• The following data matches the criteria:
FGHIJ####ABCDE############WXYZ
• The following data does not match the criteria:
FGHIJ*******************ABCDE****WXYZ
When deciding on the number of characters, remember that a
small number, such as 10, will usually result in faster
scanning time but will only cover a relatively small area. This
may reduce the likelihood of detecting sensitive data,
especially in large files. As the number increases, the area
covered also increases but scanning time might be slower.
