ossec-logtest
The ossec-logtest program is a useful tool when working with Wazuh rules. This tool allows the testing and verification of rules against provided log examples in a way that simulates the action of ossec-analysisd. This can also assist with writing and debugging custom rules and troubleshooting false positives and negatives.
