How to Configure ModSecurity in WHM

Share This Article [TheChamp-Sharing]

Hostwinds VPS, Cloud and Dedicated Server clients have the option to configure WHM to fit their needs. 

Your WHM comes with a free web app called ModSecurity. It’s helpful for dealing with common attacks, such as trojans, SQL injections, session hijacking and more. To adjust your ModSecurity settings on a global scale, log in to your WHM account and head to Security Center => ModSecurity Configuration.

What Settings Can I Change?

On the Configure Global Directives you’ll be given an interface to configure your settings.  Review the list below to see what you can adjust.

  • Audit Log Level – Change the behaviour of the audit engine and for which transactions would be logged.
  • Connections Engine – Determines the behaviour of the connections engine (SecConnEngine), if it should process rules or not.
  • Rules Engine – Like the connections engine setting, this applies to the rules engine(SecRuleEngine) and if it should process the rules.
  • Backend Compression – This setting allows disabling of backend compression, while leaving the frontend compression enabled for use.
  • Geolocation Database – Here you can specify a path to the Geolocation database that you will be using. By default, this will be blank.
  • Google Safe Browsing Database – Similar to the Geolocation Database, though this applies to Google Safe Browsing. This is blank as well.
  • Guardian Log – This allows you to set an external program to pip the transaction logs to for additional analysis.
  • Project Honey Pot Http:BL API Key – You can specify your API key for use with the @rbl operator.
  • Perl Compatible Regular Expressions Library Match Limit – Specify the match limit of the Perl Compatible Regular Expressions Library, by default this will be 1500 (even if left blank).
  • Perl Compatible Regular Expressions Library Match Limit Recursion – Similar to the option above, except this affects the Match Limit Recursion for the same library.
