How to Secure a Wireless Network from Hackers?

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 won\t 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.

WIRELESS HACK..........

WIRELESS HACK

Screens

(based on book with full instruction)

INFO

1) Unzip and install Commview, then paste the included "cv.exe" to the directory you installed it to (c:\program files\commviewwifi)

2) Open commview and install the commview drivers to a card. It should prompt you about your card and than automatically install the driver. It is important that you have 1 card that works with commview or else the rest of the tutorial will not work

3)now go to the "rules" tab and check "enable advanced rules"

4)type in the box labled formula "tods=1 and dmac=FF:FF:FF:FF:FF:FF" then type a name for your formula in the box labled name and than click add/edit.

5)it should now appear in the upper box. if it is not checked, check it.

6)now click settings>options>memory usage and turn maximum packets in buffer to 20000 (max). If it prompts you to restart it, do so. There are three funnel looking things on the main menu bar of commview. uncheck all but the first one (one labled "capture data packets")

7) now click the play button and scan for the network you want to crack.

8)once you have found it, drag the channel menu down to the desired channel and click capture.

9) now using your other adapter thats not capturing, connect to the password protected network. when it asks you for key, type in something random, i used 1234567890.

10) it should now say connected with limited connectivity. (same as being associated!!)

11)go back to your commview menu and click on the packets tab. you should see a couple of packets.

12) looking at the protocol column, you should see a couple labled IP/UDP, ARP REQ, and a couple of others. Right click on any packet labled "ARP REQ" and than click send packet, and selected. A mini menu should now appear.

13) on the mini menu, change packets per second to 2000, and rather than 1 time(s), click continuously, and Then click send.

14) now go back to the main commview window and go to the rules tab, and uncheck the rule you made.

15) You are now injecting and you should see the number of packets rising really fast.

16)to save the packets, you have to save every 20000 packets, click file, save and than in the save dialogue, remember where you saved it, and instead of saving it as an ncf file, save it as a "dump" .cap file.

17) Extract the Aircrack-NG folder.

18)open aircrack-ng-GUI that can be found in the map "bin" and select the files you saved, and than click launch.

19)Look at the list of IV's you have, and select the network you want to crack , there should be a list of alot of them, chose the one with the most ivs
