Wireless Internet

Wireless Network is the linking two or more computer without the use of any wires. Thirty years ago, entrepreneurs, real estate agents and trades people incorporated pagers and cell phones into their work and personal lives for one central reason: productivity. Wireless connections meant they could more rapidly interact with customers, partners and suppliers. Over time, wireless users have had more exposure to key business applications such as appointment scheduling, customer relationship management and supply chain management software.Threats to Wireless NetworksThreats to Wireless networks comes in all sizes and shapes, from a person who gets hold of your Wireless Access point without any approval, gripping packets out of the air and interpreting them through a packet sniffer. Many users of Wireless networks are not aware of the dangers they may encounter by just connecting to a Wireless network which is not recognized.The nature of a Wireless network opens the door for attackers and intruders who may come from every direction. The Traffic of Wireless travels in radio waves which make it can not be restricted by the building walls. Many people do feel it comfortable to work on their laptops from any place, hackers and intruders can gain access to the network from anywhere, and it can be across the street or even from the parking lot. There are some frequent threats to a wireless network which are:·        Inhale to EavesdropDue to the communication of wireless broadcast by means of radio waves, listeners who snoop up the transmission of the wireless network and can simply pick up the messages which are unencrypted. The wireless LAN unlike LANs which are wire based are not limited to the company’s are or just to a single point. The wireless LAN range is even outside the building’s boundary which therefore gives unauthorized permission to may users who can access it from any other public place. A hacker who wants to log on to the network just needs to be in the range of the network he wants to hack and will need for further enhanced skill to log on to the network.·        Denial of Service AttacksHackers who cannot have access to a particular Wireless network can however create numerous threats by flooding or even jamming the wireless network by mean of static noises which will cause the signals of a wireless network to crash and create CRC faults. These DOS (denial of service) will hack the system will force the wireless network to sternly close down or even shut down. The susceptibility is obvious and being logged in to a random network will not decrease the susceptibility to different attacks, virus or by even increasing the security. It will definitely get worse.·        Access points which are unauthorizedWireless Internet can be simply set up by anyone who has the access to a wireless connection anywhere in the business or a company. Many wireless systems are set up in home which let the users to take their laptop anywhere in the house and use internet. As a Wireless Internet can be installed by simply hooking up a WAP to a network and all they need is a wireless card in a laptop. This freedom to use Wireless network is on a high in America. They go on their own and buy everything they need and than get connected through an officer network. This unauthorized hooking up to a network may cause problems.·        Incorrectly Configured Points of AccessWrongly configured points of access are a needless but major gap in WLAN security. Many entrance points are at first configured to openly transmit SSIDs to official users. Numerous truthful administrators have wrongly used SSIDs as passwords to confirm official users. Though, since the SSID is being transmit, this big design error that permits trespasser to without difficulty take an SSID and have the person suppose they are permitted to join.SECURITY FOR THE WIRELESS NETWORKSecuring a Wireless Network is essential to prevent hackers and intruders to stop from entering into ones network. Here are some ways which can avert these situations.Changing Username and PasswordsAlmost all the accessible points of wireless networks permit an the administrator to administer their personal WIFI network by means of an account made by the administrator. This personal account will help to gain access to the WIFI network by means of a username and a password.Organizations that produce set the username and password of the system when making it. The username is at times the word administrator or admin whereas the password is a simple word like password, admin or public and even at times it is kept blank. To enhance the security of your network, it is required that as soon as the unit is installed the password is to be changed to improve the security. These passwords kept by the organizations who manufacture are normally known to the hackers and they can use it or even write it on the Internet. Many units do not have an option of changing the username but if there is an option that it can be changed than it is recommended that it should be done immediately.Lastly to continue network security, it is required that the password be changed frequently. Many computer experts say that is should be changed after in ever 1-3 months. Words are to be used which can be hard for other to conjecture.WPA Encryption turned onWIFI Protected Access is WPA which is a standard security measure for numerous wireless Networks. The WIFI protected access is not to be bemused by the Windows XP Product Activation.WIFI Protected Access can be used with Windows XP, for that the wireless clients of Windows XP is to be manually patched, the next thing is to confirm that the network adapters and wireless access points are configured properly. Following are the instructions which can be used to set up a Wireless Protected Access on several WIFI networks for people who use Windows XP.The difficulty which they may have is about average.The time needed for the setting up is around 30 minutes.Here is what needs to be doneThe first thing is to read the Wireless protected access security update in XP.Confirm if all the clients of Windows XP are running on the XP service pack 1 or Service pack 2 or 3.On every client of XP, confirm if the network adapter of the client is matched with the WZC (Wireless Zero Configuration) service. Check the products producer official website, customer service, and proper documentation of the product.For every client of XP, for WIFI protected access it is necessary to install Windows XP support patch.Make the important alteration to the Access points of the WirelessMake the important Alteration to the Adapter of Wireless network.What is needed areAccess point of the WIFI wirelessA client of Windows XP with network adapter of WIFIInternet to download the patch software.FirewallOne of the simplest and cheapest ways to secure a wireless network from a possible hacker or any other sort of an attack is a personal firewall. People who have a home router need to have the extra protection that is offered by a personal firewall.Default SSID is to be changedA network name known as the SSID is normally used by the routers and Access point. The producers often ship the products with SSID name attached. The SSID for all the devices of Linksys is usually linksys, expressing the SSID will now allow other people to break into the network. When a person finds a SSID to be default, they think of it as a network which is weakly configured and will usually attack. When the default SSID is changed it helps to enable a wireless security on the network.Allow MAC address siftEvery set of WIFI has a different identifier known as the MAC or physical address. All of the routers and Access points keep on following this addresses of each and every device connected to it. Many systems give access to the owner in the Addresses of the network, which will help to refrain from other networks to connect with the devices. This feature may not be as commanding as it seems to be. Attackers can have fake MAC addresses without difficulty.SSID disablingIn Networking a WIFI, the router or the access point of a wireless normally shows the name of the network at frequent times. Normally this feature is used by mobile spots and business where the clients of WIFI may come in and out of the networks range. It is better to disable the SSID feature so that someone else may not log on to it. This security is for home users only.Never Auto Connect to the WIFI networksWhen using wireless network at home, there is a threat of security when one logs on to a nearby wireless internet. Many connections have this setting to be automatic without letting the user know. However when you use a Wireless network at home this option should not be allowed except if required.Assigning IP addressIt is essential to assign an IP address which is set in a fixed range. Assigning a easily accessible IP address will give the advantage to the hacker who can easily gain access to it.Turning off NetworkShutting the network down when it is not in use will give the advantage to administrator. It will help the network to be attacked by hackers.ConclusionSecuring your Wireless is essential. It will prevent you from being hacked by a potential hacker and thus will gain access to all your accounts. Getting a Wireless internet is easy and simple whereas securing your network is easy as well. There are many hackers out there who are just waiting for the opportunity to log on to the network; all you have to do is not to let them have that opportunity.
