One Comment on “which of the following will prevent this type of attack…

  1. meac says:

    The WEB pages needs to be accessed, so blocking Ports is not the best option
    Port 389 is for LDAP
    Port 3389 – Port is IANA registered for Microsoft WBT Server, used for Windows Remote Desktop and Remote Assistance connections (RDP – Remote Desktop Protocol). Also used by Windows Terminal Server.
    This eliminates B & D.
    In addition to that, even if we segregate the server to a different vlan, it still must be accessible. Also as a rule, web server are place in the DMZ, which means that they are already “segregated” – This eliminates C

    So A- Input validation on the web server is the best answers.
