Update ruleset

Run the update_ruleset.py script to update the Wazuh ruleset. You should not need to make any other changes to accommodate the updated rules.

Usage examples

Update Decoders, Rules and Rootchecks:

$ /var/ossec/bin/update_ruleset.py

All script options:

Restart:
  -r, --restart       Restart OSSEC when required.
  -R, --no-restart    Do not restart OSSEC when required.

Backups:
  -b, --backups       Restore last backup.

Additional Params:
  -f, --force-update  Force to update the ruleset. By default, only it is updated the new/changed decoders/rules/rootchecks.
  -o, --ossec-path    Set OSSEC path. Default: '/var/ossec'
  -s, --source        Select ruleset source path (instead of download it).
  -j, --json          JSON output. It should be used with '-s' or '-S' argument.
  -d, --debug         Debug mode.

Configure weekly updates

Run update_ruleset.py 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.py -r
