Wireless Security Systems

Wireless LAN technology – not to respond easily to PC Network

If a rapid solution to the needs of business computing, wireless is here to stay. But the ease of installation and increase the value of security problems? This article analyzes some of the risks.

Wireless LAN Topologies

The vulnerability of a network of computers will increase in proportion to the size and nature of the network. Each access point is a safe bleach.

1)Peer to Peer:

In a peer-to-peer topology of wire, the data in the system, unless limited to two computers or a cake BNC, each message will indirectly be shared with other networked devices.
Apart from the Internet, wire-to-peer peer topology is a closed system. Stranger external activity is extremely limited.

Convert from wired to wireless, and a simple peer-to-peer computer network is an open invitation to outsidersattacks. All computer system is directly connected to any other device in-range. This open access immediately increase the need for additional security software and appliances.

2) Access Point Connections:

systems, computer network routers often use as a means of communication between different WLAN. In addition to several other features critical routers DHCP services performed. Router designed by nature to help controlsecurity issues. routers can be used as a gateway between wired and wireless networks.

On the other hand, the access point is only a portal, a bridge to access the wireless traffic to an existing wired or wireless backbone. Although access points to share common security of their router counterparts, not The functions of traffic control in a router.

The access points simply connect your laptop into a wall. None A man has real control over where even close, more people jump on the line, the slower the system works.

3) point to multipoint wireless bridge:

Bridges serve multiple LANs connected to the router. bridge wire standard is limited by the fact that only customers can wire to connect a secondary router. Since the wireless connection is involved, the safe provision is comparable to aWireless peer-to-peer PC network connection.

Wireless LAN bridge connected to each other, regardless of the distance. Even if you do not work under the bridge standard method, the necessary adjustments are few and simple. Bridging the software and tools can easily reach or network, whether wired or wireless.

Wireless bridges, two major flaws: 1) Line of site and / or primary router umbrella will be to limit the effectiveness ofbridge, 2) the security risks increase proportionally with the wireless connections available.
