Abstract
A network having a security capability where the network includes a data bus, a plurality of stations connected to the data bus and a security unit which monitors traffic on the data bus and only enables authorized data to flow along the data bus.
Claims22
A network having a security capability, the network comprising:
- a data bus;
- a plurality of stations connected to the data bus;
- and
- a security unit which monitors traffic on said data bus and only enables authorized data to flow along said data bus by causing a collision on said data bus when unauthorized traffic is detected.
A method of securing a network having at least one hub, the method comprising:
- sending blocks of data on a data bus of said hub, wherein said blocks of data each comprise at least source and destination addresses for every block of data sent on said data bus of said hub, determining if said addresses conform to a stored set of access rules;
- and
- causing a collision on the network if the output of said step of determining is false.
A security unit for a network having a data bus to which a plurality of stations are connected, comprising a traffic monitor which monitors traffic on said data bus and a collision mechanism which only enables authorized data to flow along said data bus by causing a collision on said data bus when unauthorized traffic is detected.
A method of securing a network comprising:
- sending blocks of data on a data bus of said network, wherein said blocks of data comprise at least a source address and a port address to which said source is connected;
- determining if said source address and said port address conform to a stored set of allowable source address and port address combinations;
- and
- denying access to the network for data blocks whose source address and port address do not conform to said stored set of allowable combinations by causing a collision on said data bus.
A method of securing a network comprising:
- sending blocks of data on a data bus of said network;
- causing a collision on the network if the blocks do not conform to a stored set of access rules.
