You must re-register your appliance with AMP for Endpoints console with the same data center selected for the File Reputation server.
The web reputation, Webroot, Sophos, and McAfee databases periodically receive updates from the Cisco update server. Server updates are automated and the update interval is set by the server. The Web Security Appliance maintains a filtering database that contains statistics and information about how different types of requests are handled. The appliance can also be configured to send web reputation statistics to a Cisco SensorBase Network server.
SensorBase server information is leveraged with data feeds from the SensorBase Network and the information is used to produce a Web Reputation Score. 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.
The anti-malware name returned by Adaptive Scanning. This variable is included in the scanning verdict information in the angled brackets at the end of each access log entry. Transactions blocked and monitored by the adaptive scanning engine use the ACL decision tags:. The following guidelines explain how AsyncOS uses the cache while scanning for malware:.
