I would not use static IP addresses, I would use DHCP.<br />

I would consider using certificates for machine based authentication, this is far more secure than using static addresses and simpler to manage.

hello Experts<br />
in our network we are using Cisco 3560 as core switch, Cisco 2950 as access switch for users, for more and more unauthorized computer connecting to our network, so company management board ask me to limit unauthorized computer connecting to our LAN. and we have MS Active Directory environment, one is window 2003 domain and the other one is windows 2008 domain, so l have the following question about this topic<br />
1. does Cisco ACS is necessary for 802.1x authentication?<br />
2. does it possible authenticate computer object of AD, not user object?<br />
3. could you give me some links and examples for deploy 802.1x in our LAN on Cisco platform?<br />
<br />
thank you

Network security consists of the policies adopted to prevent and monitor authorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.

Network Security

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
