I am new to Elasticsearch and logstash. I wanted to know if there's a way to get windows event logs of remote systems which login to my server(which has logstash) where the windows systems don't have any logpusher software on them.
Thanks in Advance!

I am trying to build familiarity with SIEM systems in general and decided to set up an Elastic Stack via Digital Ocean. Everything was successful and my server as localhost is producing logs. It's been interesting to tinker with visualizations and that good stuff.
Obviously my interest isn't in logs from this remote server, though. I would like to configure some devices on my home network to send logs.
Current setup on server: filebeat > logstash > elasticsearch > kibana.
When I install filebeat onto, say, my laptop and configure the .yml file in a similar way to the server (comment out elastic output, uncomment logstash output) it is not able to connect. Basically I just set the hosts to serverip:logstash port and enabled filebeat on the system. Running the setup commands leads to a "couldn't connect to any configured elasticsearch hosts".
Instead of a direct answer, can someone explain for me generally what I need to be considering for this process? What is happening when connecting outside of the server LAN? and how do I handle authentication to the server, if needed?
Thank you, really. I know that the information is out there but I am deep in a rabbit hole and having a hard time finding what I need.
By default, the HTTP API is bound to only the host's local loopback interface,
ensuring that it is not accessible to the rest of the network. Because the API
includes neither authentication nor authorization and has not been hardened or
tested for use as a publicly-reachable API, binding to publicly accessible IPs
should be avoided where possible.
Even you set "http.host: 0.0.0.0" - you need to open port for your laptop (better if you already have public IP and open it only for your laptop)
For authentication - you have to investigate xpack - security features .

So I am new to this, i installed the elk and FORTIGATE but don't know how to transfer the logs over IP..
thank you
i searched over internet but not able to find any correct way.
Try to enable syslog to logstash: here
And use fortigate filters for logstash.
I have logstash installed in a server which will process logs and publish to elastic search. But, is it possible for logstash to pull logs from remote servers (linux) without installing filebeats in those servers.
Or if filebeats can be installed in the same server as logstash and can it fetch the logs? Please help me if there is any other option as well.
Thanks in advance
Neither Logstash nor Filebeat can pull/fetch log files from remote servers, you need to have some tool installed in the remote servers that will ship the logs elsewhere.
Logstash can consume logs from message queue systems like kafka, redis or rabbitmq, for example, but you need that your remote servers send the logs to those systems anyway, so you would need a log shipper on your remote servers.
can i install elasticsearch on linux in order to run on it queries, for logs that are created on Windows servers?
My application runs on windows server, but in order to save money i want to run elasticsearch on linux, it should receive the log files from windows servers.
Kibana should run lo on linux.
You can run both on any system, both communicate via HTTP and are system agnostic.
I have configured logstash, elastic search and kibana on a Linux machine.
I tried to send logs from the Linux machine, it was successfully sent and working fine (Apache logs, system logs, log4j logs). I also tried sending it from a Windows machine. Normal logs are working fine but Windows Event Logs are not working (.evtx files).
Any idea on why it is working from Linux but not Windows?
