Hi, I am not familiar with OWASP TOP 10, but reading information
https://owasp.org/www-project-top-ten/ about this, I see this provides a list of the top 10 most critical security risks to web applications considered at the moment.
I understand your goal is to test or customize (as necessary) Wazuh to detect and alert the web attacks listed on the OWASP TOP 10.
Depending on the web attack, Wazuh could alert you with the built-in ruleset, and for uncovered cases with the built-in ruleset, you could need to customize the ruleset adding new decoders and rules that matches with the indicators of the comproise of the web attacks.
I guess you should identify and understand each attack listed on OWASP top 10 and how this can be exploded in the web applications you want to protect. In the case you want to be alerted, then you should search a mechanism how an indicator of the compromise related to the web attack can be identified on your application. For example, a log of the web application could contain the indicator of the compromise for the web attack, so if you collect the log with Wazuh and this is analyzed and you have a rule that matches with the log, this Wazuh could generate and alert.
