Cisco Cisco Email Security Appliance C160 Mode D'Emploi

containing one encrypted member along with unencrypted members will be 
considered protected. Similarly, PDF file that has no open password will not be 
considered protected, even though it may restrict copying or printing with a 
password. The following example shows protected attachments sent to a policy 
quarantine:

quarantine_protected:

if attachment-protected 

{

quarantine("Policy");

}

The 

attachment-unprotected

 filter tests whether any attachment in the message 

is not password protected or encrypted.  This message filter complements the 

attachment-protected

 filter. You might use this filter on outgoing mail to detect 

outgoing mail that is unprotected. The following example shows AsyncOS 
detecting unprotected attachments on an outgoing listener and quarantining the 
messages:

quarantine_unprotected:

if attachment-unprotected 

{

quarantine("Policy");

}
