The access log file records the information returned by the Web Reputation Filters and the DVS engine 
for each transaction. The scanning verdict information section in the access logs includes many fields to 
help understand the cause for the action applied to a transaction. For example, some fields display the 
web reputation score or the malware scanning verdict Sophos passed to the DVS engine. 
For more information about the scanning verdict information section in the access log file, see
