In this lesson, we'll examine security for wireless networks and how data can be protected from theft and malicious use.

WIRELESS NETWORK SECURITY ISSUES EBOOK DOWNLOAD

Have you noticed while you're using your home wireless network how many neighbors have wireless networks too? If you look at the list of wireless networks available to connect to, there's usually quite a few.

So if you can see them and they can see you too, how do you protect your wireless network? And what if you're a business wireless network security issues a wireless network - if you have customer data, like credit card numbers wireless network security issues your servers, how do you protect it?

Wireless network access points which connect your wireless device to the network typically have an effective range of around feet. So unless you build a home or office with spy-proof, high-tech walls and windows, people outside your building can intercept your wireless network signal.

Other potential issues with configuration include weak passphrases, weak security deployments i. This information can be used for a number of things including attempting to break existing security settings and analyzing non-secured traffic.

It is almost impossible to really prevent this type of attack because of the nature of a wireless network; what can be done is to implement high security standards using complex parameters.

Summary The nature of a wireless network is to provide easy access to end users, but this ease of access creates a more open attack surface. Unlike a wired network that requires an attacker to physically access part of the network, a wireless network only requires that the attacker be in close proximity and even this is relative.

The best attitude to take towards wireless security it to be constantly vigilant; ensure that wireless network security issues security used on a wireless network is adapted as the standards change to ensure a high level of security.

Hopefully the information within this article will be your starting point in securing your wireless networks. Get our content first.

Wireless security - Wikipedia

Combine these programs with other software that allow a computer to pretend it has any MAC address that the hacker desires, [10] and the hacker can easily get around wireless network security issues hurdle.

MAC filtering is effective only for small residential SOHO networks, since it provides protection only when the wireless device is "off the air".

Anyone with an In wireless network security issues organizational environment, where most wireless devices are "on the air" throughout the active working shift, MAC filtering provides only a false sense of security since it prevents only "casual" or unintended connections to the organizational infrastructure and does nothing to prevent a directed attack.

Man-in-the-middle attacks[ edit ] A man-in-the-middle attacker entices computers to log into a computer which is set up as a soft AP Access Point. Once this is done, the hacker connects to a real access point through another wireless card offering a steady flow of traffic through the transparent hacking computer to the real network.

The hacker can then sniff the traffic. Man-in-the-middle attacks are enhanced by software such as LANjack and AirJack which automate multiple steps of the process, meaning what once required some skill can now be done by script kiddies. Hotspots are particularly vulnerable to any attack since there is little to no security on these networks.

These cause legitimate users to not be able to get on the network and may even cause the network to crash.

Wireless security

The DoS attack in itself does little to expose organizational data to a malicious attacker, since the interruption of the network prevents the flow of data and actually indirectly protects data by preventing wireless network security issues from being transmitted.

The usual reason for performing a DoS attack is to observe the recovery of the wireless network, during which all of the initial handshake codes are re-transmitted by all devices, providing an opportunity for the malicious attacker to record these codes and use various cracking tools to analyze security weaknesses and exploit them to gain unauthorized access to the system.

This works best on weakly encrypted systems such as WEP, where there are a number of tools available which can launch a dictionary style attack of "possibly accepted" security keys based on the "model" security key captured during the network recovery.

The hacker injects bogus networking re-configuration commands that affect routers, switches, and intelligent hubs. A whole network can be brought down in this manner and require rebooting or even reprogramming of all wireless network security issues networking devices.

It is not necessary for the attacker to be in the area of the network using this exploit. By using a process that targets the Windows wireless stack, it is possible to obtain the WEP key from a remote client.

For closed networks like home users and organizations the most common way is to configure access restrictions in the access points.

Those restrictions may include encryption and checks on MAC address. For commercial providers, hotspotsand large organizations, the preferred solution is often wireless network security issues have an open and unencrypted, but completely isolated wireless network.
