Triton AP-Websense SIEM Logstash Output Configuration

The following configuration will make it easier to parse Syslog messages sent from your Websense appliance to your ELK stack.

If you need assistance setting up SIEM integration with Websense you may follow their official guide which is fairly straightforward.

Additionally here’s the documentation for category IDs and classifications which helped tremendously in trying to identify what event IDs correlated to what events:

TRITON AP-WEB and Web Filter & Security, v8.3.x

Finally: Here’s the Logstash configuration:

input {
  tcp {
    port => 5000
    type => websense
  }
}



filter {
 if [type] == "websense" {
grok {
match => { "message" => "%{IPV4:SourceIP}\s%{DATA:vendor}\s%{DATA:Product}\s%{DATA:Product_Version}\s%{DATA:Action}\s%{DATA:SeverityIgnore}%{INT:Severity}\s%{DATA:CategoryIgnore}%{INT:Category}\s%{DATA:UserIgnore}%{USERNAME:Username}\s%{DATA:sourceIgnore}%{IPV4:SourceHost}\s%{DATA:PortIgnore}%{INT:SourcePort}\s%{DATA:HostIgnore}%{DATA:DestinationHost}\s%{DATA:DestinationIPgnore}%{IPV4:DestinationIP}\s%{DATA:DestPortIgnore}%{INT:DestPort}\s%{DATA:BytesOUtIgnore}%{INT:BytesOut}\s%{DATA:BytesIn}%{INT:BytesIn}\s%{DATA:HttpResponseIgnore}%{INT:HttpResponse}\s%{DATA:HttpMethod}\s%{DATA:ContentType}\s%{DATA:UserAgent}\s%{DATA:HttpProxyStatusIgnore}%{INT:HttpProxyStatus}\s%{DATA:Reason}\s%{DATA:DispositionIgnore}%{INT:Disposition}\s%{DATA:Policy}\s%{DATA:RoleIgnore}%{INT:Role}\s%{DATA:DurationIgnore}%{INT:Duration}\s%{GREEDYDATA:URL}" }
 }
}
}

Note: you may un-comment the Geo-Mapping information to get Geo-Ip information about the outbound connections.

Here’s an Kibana query to identify potential threats based on the outbound connection category:

Category: 1 OR Category: 15 OR Category: 23 OR Category:  25 OR Category: 29 OR Category: 65 OR Category: 66 OR Category: 67 OR Category: 70 OR Category: 75 OR Category: 80 OR Category: 98 OR Category: 99 OR Category:  100 OR Category: 109 OR Category: 113 OR Category:  114 OR Category:  115 OR Category:  117 OR Category: 128 OR Category:  138 OR Category:  153 OR Category:  154 OR Category:  156 OR Category: 164 OR Category: 166 OR Category:  167 OR Category:  172 OR Category:  192 OR Category:  194 OR Category: 205 OR Category: 206 OR Category:  207 OR Category: 213 OR Category: 214 OR Category: 217 OR Category:  216 OR Category:  218  OR Category: 219 OR Category: 220 OR Category: 221

Here’s an example of a dashboard created based on the information collected.

Hope this helps!
