Incase anyone needs more clarification on how to get clients to trust self-signed certificates, see this latest video: th-cam.com/video/zPkSiojo7rA/w-d-xo.html We explain how self signed certificates is potentially more secure than publicly signed certificates.

I haven't used postman in a while, so I don't remember how the user interface works these days. But in theory, it should work the same if you know how to pass in options for data payload, credentials, http headers and option for CA cert if applicable.
Hello, first of all, thank you for your video, it's great content well explained ! I'm faced with a very particular problem that seems simple at first but finally, after a lot of research, I'm totally stuck. I've followed your video to the letter, but I'm having a particular problem with the certificate on the Kibana side. The certificate generated on the Elasticsearch side is valid and recognized by my browser. The difference with your infrastructure is that my Elasticsearch service and Kibana run on the same machine, so I had to adapt the certificates to my case. I've noticed that my Kibana service won't start, and when I look at the errors, I get the following error message: License information could not be obtained from Elasticsearch due to ConnectionError: unable to verify the first certificate error The message is fairly clear, but I don't know exactly where the problem is, I first thought it was a communication problem with my Elasticsearch, but it's going through the encrypted token in the variable, so I don't think it's coming from that. As for the certificate part, I've just reused the previously generated ca but the certificate generated behind it doesn't seem to be recognized. Have you ever had this problem?
Thanks for your message. I've encountered so many different certificate issues, your case might be one of them. You will have to email me through our website. Then you'll have to the exact shell commands you used, share your yml files etc... Then I'll be able to comment more via email

I have connected the agents to the fleet server by adding --insecure command as I didn't assign a SSL. My question is, if I did self signed SSL after installing the agents (--insecure) do I have to remove the agent from the servers and Install it again or it will be by default changed "I doubt". What should I do?
Hey there I haven't looked to extensively in to this. But I use to just Uninstall then reinstall. That worked for my purposes and didn't seem to cause any problems
Great videos, thank you. At 7:48 you mention a password that was being requested for the http.p12. That password can be found with the command. /usr/share/elasticsearch/bin/elasticsearch-keystore show xpack.security.http.ssl.keystore.secure_password Cheers
If I host the elk stack in the cloud, the. I use the DNS manager of the place where I bought the domain then pointed the A record to the IP address of the machine I'm working with. If I am hosting locally, then I modify host files of each machine so the appropriate domains point to the appropriate local IP address
Hi @evermighttech , I have the same question as @ati43888, I have followed this guide and it works perfectly; however, at the moment of including a new elasticsearch node to create a cluster the issue is not clear; I tried to apply what you indicate in "Setup Elasticsearch Cluster + Kibana 8.x" but it does not work, if you can do us the favor of expanding this video including the explanation of a cluster with Self-Signed SSL it would be very helpful.
hello, the Setup Elasticsearch Cluster + Kibana 8.x should describe end to end of using self-signed certs. If you email me the specific error, then maybe I can comment more. You can find our contact form on evermight.com
Sir, I am having two doubts kindly clarify. 1. while generating the certificate we are passing either IP/DNS. In case of generating the certificate for elastic search cluster for 3 nodes. Whether we have to generate certificates for all three nodes in the cluster by passing the respective IP/DNS. 2. Why the ownership has been changed to user "elasticsearch" and "kibana" what implications we get it if the same hasn't been changed. whether change of the ownership for entire folder of /etc/elasticsearch and /etc/kibana or to be applied for any specific file.
1. For each node in your cluster, the `xpack.security.http.ssl` the common name/SAN needs what has been issued by the certificate. So if each node has a specific address, then yes, you need a certificate for each node. If you watch my elastic cluster video, you see that I have one cert for each node like node2..com, node3..com etc... That's my suggestion based on what iv'e done, but if you discover a better way, let me know! 2. Earlier in the year, I got a lot of unusual start up errors and file read/write permissions . I found changing ownership to elasticsearch/kibana users got rid of those errors for me. I don't know if such steps are necessary in the latest versions of ELK, but I've continued the practice using elasticsearch/kibana users.
@@evermightsystems Thank you for swift response. In my case i am trying with ES cluster with 3 nodes and there is only IPaddress and no domain name mentioned and I am generating self signed certificates. If i have generated 3 self signed certificates separately then in fleet and elastic search agent configuration which server certificate details are to be passed for option fleet-server-es-ca. 2. Have you ever faced the issue of slowness in loading the page of fleet in kibana.
Nice video. Is there a way around SEC_ERROR_UNKNOWN_ISSUER? I used windows server CA for my certificates and my Windows Servers can browse to the Kibana URL without any error, but when I browse to the Kibana URL with my Ubuntu servers that are hosting elasticsearch, kibana, & filebeat I run into that error which is telling me my Ubuntu machines do not trust the CA. The only way I find around the error on my ubuntu machines is to add the CA to the /usr/local/share/ca-certificates directory and also importing the CA into the browser you are using.
Importing the ca is the correct solution to the SEC_ERROR_UNKNOWN_ISSUER message. This approach is intentional and the way self signed certificates and self created CA are supposed to work . And for the purposes of elasticsearch, it actually makes the entire platform more secure than public CA and public certificates, because with private CA approach, none of the CA certificates are automatically trusted. You as the technical administrator must manually authorize the sharing of any keys, certs, ca etc... As far as I can tell, this was an intentional architectural security decision by the elastic team. Nothing should be automatically trusted.
Greetings, First thank you, follow all your kibana and filebeat installation steps. And I have a server running collecting netflow data from my router. However I have a problem the graphics are only 30 minutes of data and they are already overwriting and I have 1.5tb of storage, how do I fix this? Do I need to make any other adjustments to use netflow? The router that sends has a traffic of 30~40Gbs
Hi Michell thanks for your message. I could try to look into this issue with you over a zoom call this week . If you contact us through our website, we can schedule something?
@@evermightsystems By default the filebeat was to keep the data and graphics until the disk was full? I thought this was just a configuration tweak. Follow all your steps to configure Kibana+Elastic Search and then filebeat. Clean server only the steps of the videos
Is there a video (is this it?) where you only used the certs that come by default with elastic for configuring kibana? Eventually logstash and filebeat will be implemented, starting in our lab first.
I don't have a video yet that uses the default certs. But you can definitely use it. The http.p12 is the full chain/keystore. The http_ca.crt is the certificate authority file that you would continue using (instead of using the ca.crt that I made in my video). Someone else commented recently that you can get the password to the http.p12 file with this command: /elasticsearch/bin/elasticsearch-keystore show xpack.security.http.ssl.keystore.secure_password . I haven't tried it yet, but had I known that in advance, and if it works, then I probably would have used the http_ca.crt and http.p12 to sign new SSL certificates instead of starting a new certificate authority. Anyway, you have a lot of options...don't start a new CA, start a new CA, use different CA for various sets of self signed ssl etc... the combinations are endless!
It was a very good explanation. Thanks. But how to use self signed certificate in 3 node clusters. Could you please improve this video based on this question.
I believe the video on setting up elastic cluster uses self signed certificates. Cluster nodes communicate on port 9300 which should ALWAYS use self signed certificates unless you have explicitly put measures in place deal with security concerns that arise from using publicly signed certificates on port 9300
th-cam.com/video/TfhcJXdNSdI/w-d-xo.html this was the video on setting up elastic clusters with 5 nodes. And we used self signed certs as suggested by elastic documentation. Let us know if we missed something

Hi, can u instruct to deploy ELK stack helm chart v8.5.1 on Kubernetes?
it's on task list, but i might need utnil end of year to produce the guides. A lot of client project deadlines these past few months.
can u use docker compose ?
