7.7 NetBIOS
Filtering
NetBIOS (Network Basic Input/Output System) is a program that allows applications on
different computers to communicate within a local area network (LAN). NetBIOS is used
in Ethernet, included as part of NetBIOS Extended User Interface (NetBEUI). Resource
and information in the same network can be shared with this protocol.
But the more computers are used recently, the more strong security is required. To secure
individual customer’s information and prevent information leakages in the LAN environ-
men, the hiD 6615 S223/S323 provides NetBIOS filtering function.
