Wazuh - operational and can add agents - now what

DustinB3403

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

Oh I made a typo! Its supposed to be 13102

@DustinB3403

This is how you verify rule ID numbers

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?

DustinB3403

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
