Abstract
A security server for use in a telecommunications network is arranged to receive a message; determine whether the message is from a known source or an unknown source and, depending on the result of the determination, modify the message; and forward the message within the telecommunications network. A network processing element for use in a telecommunications network is arranged to receive a message from another network element; determine whether the message has been modified and, depending on the result of the determination, perform one or more security checks in respect of the message.
Claims48
A security server for use in a telecommunications network, the security server configured to:
- receive a message;
- determine whether the message is from a known source or an unknown source and, depending on a result of the determination, modify the message;
- and
- forward the message within the telecommunications network.
A network processing element for use in a telecommunications network, the network processing element configured to:
- receive a message from another network element;
- determine whether the message has been modified and, depending on a result of the determination, perform one or more security checks in respect of the message.
A telecommunications network comprising a security server and a network processing element, the security server being configured to:
- receive a message;
- determine whether the message is from a known source or an unknown source and, depending on a result of the determination, modify the message;
- and
- forward the message to the network processing element.
A method of performing a security check on a message in a telecommunications network, the method comprising the steps of:
- receiving a message;
- determining whether the message is from a known source or an unknown source and, depending on a result of the determination, modifying the message;
- and
- forwarding the message within the telecommunications network.
A security server for use in a telecommunications network, the security server configured to:
- receive a message;
- determine whether the message is from a known source or an unknown source;
- and
- forward the message within the communications network in a manner dependent on a result of the determination.
A telecommunications network comprising a security server and a network processing element, the security server being configured to:
- receive a message;
- determine whether the message is from a known source or an unknown source;
- and
- forward the message to the network processing element in a manner dependent on a result of the determination.
A method of performing a security check on a message in a telecommunications network, the method comprising the steps of:
- receiving a message;
- determining whether the message is from a known source or an unknown source;
- and
- forwarding the message within the communications network in a manner dependent on a result of the determination.
A security server for use in a telecommunications network, the security server configured to:
- receive a message;
- and
- determine whether the message is from a known source or an unknown source and,
- depending on a result of the determination, determine a subsequent action to be taken in respect of the message.
A method of performing a security check on a message in a telecommunications network, the method comprising the steps of:
- receiving a message;
- and
- determining whether the message is from a known source or an unknown source and, depending on a result of a determination, determining a subsequent action to be taken in respect of the message.
A security server for use in a telecommunications network, the security server comprising:
- receiving means for receiving a message;
- determining means for determining whether the message is from a known source or an unknown source and, depending on a result of the determination, modify the message;
- and
- forwarding means for forwarding the message within the telecommunications network.
A network processing element for use in a telecommunications network, the network processing element comprising:
- receiving means for receiving a message from another network element;
