Tiivistelmä
Local Area Network (LAN) refers to the local area coverage of a computer network. In general, communication data packets which can be transmitted between any two network nodes based on broadcast transmission have been widely used in local area network at present. Not only can they be received by a network card in those two network nodes, but they can also be received by a network card in any other network node on the same Ethernet. Therefore, a hacker can track, unpack all packets and steal critical information in Ethernet when they access any node on the Ethernet. This poses security risks in Ethernet.
In order to ensure local area network security. This thesis analyzes several solutions which are used firewall technology, encryption technology, network segmentation and VLAN technology. The thesis introduces three ways of establishing a preliminary LAN Protection System which are: designing a LAN structure, designing LAN security management structure and configuring a firewall.
