![]() ![]() It was a bit of a puzzle, trial and error, but this is what my input finally looks like: input Ĭonvert => Leave the Filebeat service stopped until we configured Logstash to accept the logs. E:\Program Files\Microsoft\Exchange Server\V14\TransportRoles\Logs\MessageTracking\MSGTRK2*.LOG I used a standard installation, and this is what my filebeat.yml looks like: filebeat: To send these files to ELK, I used Filebeat. More about Message Tracking can be found here. Feel free to adjust the filters to any other version. Also the fields in the log files may differ between versions, so once again, the setup I post here is for Exchange Server 2010. At least in the 2010 version I am using, I was told in Exchange Server 2013 you have to turn it on manually. To process, connect the Pipeline to a Stream of messages.It’s been a while, but today I thought it was time to finish my ELK input for monitoring Microsoft Exchange Server.Įxchange Server logs the mailflow to logfiles in \Program Files\Microsoft\Exchange Server\V14\TransportRoles\Logs\MessageTracking by default. Without the plugin, it would not be possible to save the rules because of the missing functions. To use the last two Stages, you will need to install the Graylog threat intelligence plugin on all your Graylog Nodes. Please note, due to the amount of messages produced by sysmon, you should enable the delivery to Graylog in batches so that you are able to scale and size the environment. In this Pipeline, we will have the following Stages containing rules: The rules will now need to be added to a new Pipeline. - Enables searches like threat_indicated:true set_fields(sysmon_dns_lookup_ip_whois) let sysmon_dns_lookup_ip_whois = whois_lookup_ip(to_string($message.query_answer), "sysmon_dns_lookup_ip") Enable and carefully watch latency and performance. Let sysmon_src_ip_answer_intel = threat_intel_lookup_ip(to_string($message.query_answer), "sysmon_src_ip") so you know if your IP is seen as a problem this is useful if dealing with non internal IPs ![]() Set_fields(sysmon_lookup_ip_answer_intel) Let sysmon_lookup_ip_answer_intel = threat_intel_lookup_ip(to_string($message.query_answer), "sysmon_dns_lookup_ip") if we do not monitor the dns, then this might be nice to have Let sysmon_dns_lookup_intel = threat_intel_lookup_domain(to_string($message.query_domain), "sysmon_dns_lookup") look up the requested DNS captured by sysmon To save CPU cycles, only run if there is something to look up - Needs installed Graylog Threat Intel plugin : Remove_field("winlogbeat_event_data_DestinationIsIpv6") Remove_field("winlogbeat_event_data_SourceIsIpv6") ![]() Remove_field("winlogbeat_record_number") Remove_field("winlogbeat_event_data_ProcessId") Remove winlogbeats fields we don't need Remove_field("winlogbeat_provider_guid") Set_field("sysmon_data_provider_gui", to_string(fix)) The important step is to now replace the Event name with [$", to_string($message.winlogbeat_provider_guid)) ![]() Since we only want the Windows Event Logfile, simply disable the filebeat backend in the collector sidecar configuration file.īack to the Graylog Web interface! We assume you have a beats input already running as global input on Port 5044 with no TLS.įollow the step-by-step guide to create a configuration and choose WinlLogBeat for the type of configuration. When installing the collector sidecar, leave the tag windows so you will be able to configure everything from the Graylog web interface. This will already include winlogbeat so you only need to install and configure one package. The documentation provides a step-by-step guide to install the collector sidecar. We will walkthrough the steps below and once implemented, you will be able to easily monitor your data and react to any unusual requests. Note, the threat intelligence plugin is still in testing mode. The plugin adds processing pipeline functions to enrich log messages with threat intelligence data. For added protection, you can also install our threat intelligence plugin. After installation and configuration, you can configure your already running winlogbeat to get the sysmon messages into Graylog. The Microsoft System Monitor (sysmon) that provides you information about your Windows also writes messages to the Windows Event Log. This will be useful if you are running Windows Servers in your environment or have a fleet of workstations that you are responsible for and want to have the additional information added to your already present central logfile system. Now we’ll show you how to use the winlogbeat to get the Windows Event Log over to your Graylog Installation. Previously we discussed how you can use Graylog Collector Sidecar to configure Filebeat and work with Logfiles. ![]()
