Wireless Internet technology is increasingly deployed in offices, public environments, and as well as by the internet users at home. Due to this rapid growth of the internet, its security compromised. When wireless technology was first introduced, there were relatively few dangers. It was difficult for the hackers to get hands on the new technology because it was not common yet. However, Our current wireless protocols and encryption methods have associated with many security risks. Security can also compromise because of carelessness and ignorance at the user and IT level.
Hacking methods have become much more classy and innovative with wireless access. Hackers have found wireless network easy to break into as compared to a wired network. They can easily hack into our systems through any loop in network security. Thus there is a need for some security parameters to keep the networks secure.
What is Wireless security?
Wireless security is the process of preventing a network from unauthorized access by designing, implementing and ensuring safety over a system. Windows security is just an aspect of computer security; however, organizations are more vulnerable to security breaches.
The most common types of security are Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WAP). WEP is a weak security protocol. Its password can easily crack within minutes through a basic laptop and readily available tools. In 2003, Wi-Fi Protected Access (WAP) replaced it, and it was a quick alternative to improve the network security.
Threats to Wireless Network:
There are some threats exists to the Wireless networks. Used methods have briefly discussed below:
Denial of Service:
In DOS attack the hacker continuously bombards the system with bogus requests or rare traffic. This cause the user to not be able to access the network and may even cause the network to crash.
Passive capturing is performed by merely getting within the range of network and then obtaining data. This information can be used to break-in or spoof in the organization.
Man, in the middle attack:
In a man in the middle attack, the attacker places him between two devices often a web browser and web server and then intercepts or change the communication.
In this method, the hacker injects bogus re-configuration commands that can affect routers, intelligent hubs, and switches. A whole network can be brought down using this method and then it will require rebooting or even reprogramming of router.
There is a range of Wireless security measures that can prevent your network from any unauthorized access. Some of them are:
A simple way to protect your system is to hide your SSID unless you need to give access to someone.
MAC ID Filtering:
A simple and effective way is to allow only authorized MAC address to connect to your network. This will prevent unauthorized mac addresses to connect to your system.
End to End Encryption:
To keep your network safe, the application layer of the system should be encrypted and authorized using technologies like SSL, SSH, and PGP, etc.
Static IP Address:
WAP provides IP addresses to clients via DHCP. If the clients set their IP addresses, then it is more difficult for an intruder to log onto the network. It supplies little protection against an attacker.
