Run the update_ruleset script to update the Wazuh ruleset. You should not need to make any other changes to accommodate the updated rules.
Update Decoders, Rules and Rootchecks:
# /var/ossec/bin/update_rulesetAll script options are available on the :ref:`reference manual <update_ruleset>`.
Run update_ruleset weekly and keep your Wazuh Ruleset installation up to date by adding a crontab job to your system.
One way to do this would be to run sudo crontab -e and, at the end of the file, add the following line
@weekly root cd /var/ossec/bin && ./update_ruleset -r
