Error handling security considerations for the IBM WebSphere Application Server용 DMZ 보안 프록시 서버
The overall security level of the IBM® WebSphere® Application Server용 DMZ 보안 프록시 서버 is partially determined by the choices made regarding the handling of custom errors.
You can define a custom error page for each error code or a group of error codes on errors generated by the proxy server or the application server. This is done using HTTP status codes in responses to generate uniform customized error pages for the application. For security reasons, you can ensure that the error pages are read from the local file system instead of being forwarded to a custom remote application. Choosing this option limits the code path and eliminates the need for a potentially unauthorized application to be run as the error message is generated based on a flat file.
