How To Secure Your Wireless Network

Convenience of Price

Wi-fi networks have the capacity to make business enterprise networking much more valuable and economical. It is a lot easier to set up a new user with a wi-fi network connection than to give a wired connection from the nearest switch and do a complete installation process.

Secure Your Wireless Network

To control a wired network is an easy task as all the data is in the cables that connect the computer to the switch and cables can be physical control. While in a wi-fi network, no cables are used, a medium which is used here is air. This wireless network has a particular range up to which any user can connect. For example, if its range is 100 meters, then practically every person within 100 meters of range can access this wireless network.

Threats to Wireless Network Security

Accessing a wi-fi network by an unauthorized user is a significant threat to your wireless network. Besides this here are some other threats whose detail is given below: –

  •    Rogue WLAN’s – Whether your corporation has formally sanctioned w-fi network or not, wireless routers are comparatively cheaper, and bold users may plug the unauthorized system into the network. These rogue wireless networks are considered insecure and pose a danger to the community network at massive.
  •    Spoofing Internal Communications – If there comes an attack from outside the network, it can be recognized. Such as If an attacker connects with your WLAN, they can spoof communications that seem to come from internal domains.

  •    Stealing Network Resources – Even if an outsider does not assault your computer’s data, they may connect to your WLAN and hack your network bandwidth to browse the internet. They can leverage the higher bandwidth discovered on most business networks to download different games, movies, and video clips, using your costly network resources and impacting system performance for your valid users.

Network protection from WLAN

LAN segmentation is utilized by many companies to divide the network into smaller, greater possible compartments. The usage of distinctive LAN segments has various advantages. It can enable an enterprise to enlarge their network, reduce community congestion, compartmentalize problems for extra green troubleshooting, and enhance protection via shielding different VLAN’s from each other.

The progressed safety is an amazing purpose of setting your WLAN up on its own VLAN. You may permit all the wi-fi gadgets to connect with your WLAN but protect remaining your internal community from any troubles or attacks which can occur on the wi-fi network. The use of a firewall, or router access control lists, you may create restriction of communications between the WLAN and remain another network.

Secure WLAN Access

Separating your WLAN from the rest of your network will help to ensure the inner community from any trouble or assaults in the wireless community. However, there are still different steps you may take to shield the wireless community itself. With the aid of encrypting your wireless communications and requiring users to authenticate while connecting, you can make certain unauthorized customers do not interrupt your WLAN and that your wi-fi information cannot be intercepted.

Wireless Encryption

The best way to ensure that unauthorized users do not use your wireless network is to encrypt your wi-fi connection.

The authentic encryption technique is Wired Equal Privacy, was determined to be flawed. WEP depends on a shared key, password or to restrict the right of entry. Any user who is aware of the WEP key can be part of the wi-fi community. There has been no mechanism into WEP to change the key automatically, and there are a lot of tools that can hack the WEP key in a minute, so it will not take a long time for an attacker to get entered to a WEP-encrypted wi-fi network.

While the use of WEP may be a little bit better than keeping network without encryption, it is not enough for protecting a business community. The following technology of encryption WPA, is designed to leverage an 802.1x-compliant authentication server, but it may additionally be run just like WEP in Pre-Shared Key) mode. The principle development from WEP to WPA is the usage of Temporal Key Integrity Protocol, which dynamically modifies the key to prevent the cracking strategies used to interrupt WEP encryption.

To secure wireless data from being intercepted and to prevent unauthorized access to your wi-fi network, your WLAN have to be set up with at least WPA encryption, and WPA2 encryption is highly preferred.
