How to Secure a Wireless Network from Hackers?

Updated on: 2012-03-22 || Source: computerfreetips.com

The reason we secure a wireless network is to stop people from using the services of our network who don't have permission to utilize them. It is harder to secure a wireless network from hackers as compared to a classic wired network. This is due to the fact that a wireless network can be accessed anywhere inside the range of its antenna.

In order to secure a wireless network from hackers, we should take proper steps to save ourselves against security issues. If you don't secure a wireless network from hackers, you might end up without its service. The consequence might also include the utilization of our network to attack further networks. To secure a wireless network from hackers, you should follow these simple wireless networking tips:

1.       Strategic antenna placement:

The first thing you have to do is to position the access point's antenna in a place which restricts the range of its signal to go further than the required area. You should not put the antenna close to a window because glass can't obstruct its signals. Place it in a central location of the building.

2.       Use WEP:

WEP stands for Wireless encryption protocol.  It's a customary technique for encrypting traffic on a wireless network. You should never skip it as that will allow hackers to get instant access to the traffic over a wireless network.

3.       Change the SSID, disable the broadcast of SSID:

SSID stands for service set identifier.  It is the recognition thread utilized by the wireless access point due to which the customers are capable of starting connections. For every wireless access point arranged, select an exclusive as well as unique SSID. Also, if it's attainable, hold back the broadcast of the SSID out over the antenna. It wont appear in the listing of offered networks, while being able to provide services as usual.

4.       Disable DHCP:

By doing this, the hackers will have to decode the TCP/IP parameters, subnet mask as well as the IP address in order to hack your wireless network.

5.       Disable or modify SNMP settings:

Change the private as well as public community settings of SNMP. You can also just disable it. Otherwise the hackers will be able to utilize SNMP to get significant info regarding your wireless network.

6.       Utilize access lists:

For additional security of your wireless network, and if your access point support this feature, employ an access list. An access list lets us determine precisely which machinery is permitted to attach to an access point. The access points which include the access list can employ trivial file transfer protocol (TFTP) now and then in order to download modernized lists to steer clear of hackers.
