Question

How to manage Web Application Firewall (ModSecurity) on Plesk server via CLI?

Answer

Web Application Firewall (ModSecurity) management is available within the Plesk CLI utilities server_pref and
subscription
.

For example:

  • In order to check ModSecurity status:

    # plesk bin server_pref --show-web-app-firewall

  • To turn ModSecurity on - specify the required rule set and other WAF settings - in this example, the OWASP ModSecurity Core Rule Set (CRS) on Apache is enabled with the weekly rule set update period and "Fast" redefined set of values:

    # plesk bin server_pref --update-web-app-firewall -waf-rule-engine on -waf-web-server apache -waf-rule-set crs -waf-rule-set-update-period weekly -waf-config-preset fast

  • To turn on the web application firewall settings for the website example.com:

    # plesk bin subscription --update-web-app-firewall example.com -waf-rule-engine on 

  • To manually update ModSecurity ruleset:

    # plesk daily UpdateModSecurityRuleSet

Refer to the following documentation articles for additional details:

Plesk Documentation and Help Portal - Reference for Command-Line Utilities, Plesk for Linux - Using command line utilities - server_pref
