      @IRJ How are rulesets installed?

      They are in your /var/ossec/rules directory. You should not change those rules ever.

      Any new rules, you will need to put in /var/ossec/etc/rules like I explained in previous post.

        Okay, so I've added that file to /var/ossec/etc/rules and entered what you provided (probably should verify that for my own sanity). Do I need to "enable" it or refresh the rules?

          You need to restart the wazuh manager and agents

          You can restart agents from the manager by using this command /var/ossec/bin/agent_control -R -a

          You can restart wazuh-manager by using systemctl restart wazuh-manager

            @IRJ so I can't start the wazuh-manager because ossec-analysisd: ERROR: Invalid option 'frequency' for rule '100100'.

            I'll have to look into that in a bit, have a meeting to run too.

              2-9999 are allowed values

                I made an error writing the rule. frequency and timeframe go up next to rule_id and level . I edited my previous post and fixed it

                Just like rule 5703 here https://github.com/wazuh/wazuh-ruleset/blob/master/rules/0095-sshd_rules.xml

                      13202 is the rule number not frequency or timeframe

                        Does rule 13202 not exist? you should be able to find it in your rules folder under 0200-smbd_rules.xml file

                              This is how you verify rule ID numbers

                              c2826081-0d96-4382-a777-fa5644cf47e9-image.png

                              Then you open the rule file

                                @IRJ so a lot of this works out of the box, one question I have is how the heck do I get the details of specific events.

                                In the below I specifically failed a login attempt a few times, How can I find out what client was attempting to login to this server and failed?

                                  Or I guess an even better question is there some free training on wazuh? I did a very brief search and found a few things, but it's all over the place as to what may be useful.

                                      Nope, I should make a course on Udemy, though
