Log handler rule sets Monitoring Logging 8 Log handler rule sets are top-level rule sets with nested rule sets that include logging rules. This section describes the nested logging rule sets that are provided by default on the appliance. Access Log This nested logging rule set records requests for access to the web sent from users of your network. Nested logging rule set — Access Log Criteria — Always The rule set contains the following rule: Write access.log Always –> Continue — Set User-Defined.logLine = DateTime.ToWebReporterString + “ ”” ... FileSystemLogging.WriteLogEntry (User-Defined.logLine) The rule uses an event to fill a log file entry with parameter values relating to requests sent by users, such as user names or request headers. It uses another event to write this entry to a log file. The log file entry is specified as a parameter in both events. The log that stores the log file is specified by the settings of the write event. Values for the following parameters are set and logged by the events of the rule (properties used by the set event are shown in italics): • Date and time — DateTime.ToWebReporterString • User name — Authentication.UserName • Client IP address — String.ReplaceIfEquals (IP.ToString(Client.IP), “”, “-”) • Response status — String.ReplaceIfEquals (Number.ToString (Response.StatusCode), “”, “-”) • Request header — RequestHeader.FirstLine • URL category — List.OfCategory.ToString (URL.Categories) • URL reputation — String.ReplaceIfEquals (URL.ReputationString, “”, “-”) (URL.Reputation) • Media type — MediaType.ToString (MediaType.FromHeader) • Body size — String.ReplaceIfEquals (Number.ToString (Body.Size), “”, “-”) • User agent — Header.Request.Get(“User-Agent”) • Virus and malware names — List.OfString.ToString (Antimalware.VirusNames) • Block action ID — Number.ToString (Block.ID) The logging rule applies whenever a request for access to the web is received. The two rule events for filling and writing a log entry are then executed. Processing continues with the next rule or rule set. McAfee Web Gateway 7.1.5 Product Guide 295
