WorldExtend® IronDoor Ø-Listener™ Configuration
WorldExtend IronDoor 3.5 with Ø-Listener technology provides secure application publishing and the other features of WorldExtend IronDoor via our patent-pending Ø-Listener technology that effectively guards against Denial of Service (DoS) attacks which can cripple a network.
Any network that provides remote access incorporates listeners to recognize an incoming request and facilitate a connection. Typically, the platforms that enable remote access require that listeners be constantly posted to all open ports so that they are ready to establish a connection in the event of a network request. This receptiveness is a vulnerability that hackers can exploit by sending unauthorized messages to the open listener or even flooding it in the case of DoS attacks.
With IronDoor 3.5 and Ø-Listener technology the assignment of listeners is a reactive process, rather than an open, available state. Listeners are only assigned to a port once a user has been validated by IronDoor 3.5. This advanced screening of user requests heightens your network security and prevents unnecessary congestion of network resources – only requests that have been validated as coming from an authorized user will generate a listener to acknowledge the request and process it. Once the connection is validated, a secure connection is established between the remote user and your network.
IronDoor 3.5 Ø-Listener technology has further refined this “just-in-time” listener delivery by allowing you to restrict the assignment of listeners to a designated range of ports on your firewall. This reduces the likelihood of a port probing attack finding an open listener, and safeguards the authentication process.
If you do not have the IT resources to appropriately configure IronDoor 3.5 with Ø-Listener technology , you can rely on the consulting expertise of WorldExtend® field engineers or consider our hosted WorldExtend® IronDoor 3.5 ™ solution.
