Remediation Steps
Follow the steps below to remediate this finding on Microsoft IIS webserver.
IIS does not include a Server header with version details by default, but if it does, install the URL Rewrite module and add an outbound rule to remove or replace the header:
<rewrite> <outboundRules> <rule name="Remove Server header"> <match serverVariable="RESPONSE_SERVER" pattern=".*" /> <action type="Rewrite" value="" /> </rule> </outboundRules> </rewrite>
