Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

The predefined Sarbanes-Oxley (SOX) policy template uses the Corporate 
Financials classifier to search for non-public corporate financial information.

Examples:

2009 Cisco net sales, net income, depreciation

 (Match)

FORM 10-Q 2009 I.R.S. Employer Identification No.

 (Match)

A number of policy templates require customization of one or more classifiers, 
which involves creating a regular expression to search for identification numbers 
that may be linked to confidential information, such as a custom account number 
or patient identification number. The style of regular expressions used for content 
matching classifiers is the POSIX Basic Regular Expression style regular 
expressions. 

Use the following table as a guide for creating regular expressions for classifiers:

Regular expressions for classifiers match a string if 
the sequence of directives in the regular expression 
match any part of the string. 

For example, the regular expression 

ACC 

matches the 

string 

ACCOUNT

 as well as 

ACCT

. 

Use brackets to indicate a set of characters. 
Characters can defined individually or within a range.

For example, 

[a-z]

 matches all lowercase letters 

from 

a

 to 

z

, while 

[a-zA-Z]

 matches all uppercase 

and lowercase letters from 

A

 to 

Z

. 

[xyz]

 matches only 

the letters 

x

, 

y

, or 

z

.
