Network protection is a complete anda necessary set of activities, which includes the organization, the creation of software, as well as the adoption of physical and technical measures. Only such a complex is able to ensure the maximum achievement of the properties of the information resource.
Today, care must be taken toencryption of specific properties of information resources. Protection of networks is possible if necessary measures are taken. There are several main properties of the information network:
If the network is not password-protected, then wirelessUnauthorized users can connect to the connection. In most cases, they do it not intentionally, but only because modern mobile devices and gadgets automatically connect to the network. The protection of computer networks will prevent unplanned flow of traffic. But in some cases the situation can worsen. Sometimes users use an unprotected connection to start downloading illegal content.
If the owner of the personal computer does nothas taken no measures to protect the network from unauthorized access by third parties, then he exposes himself to danger. It is necessary to go into the interface of the router and change the data of access to the network. The address of the router is indicated in the instruction that is issued at the time of the purchase of such a device. If it does not exist, you can determine the IP address using your own network device. To do this, the browser window opens, where you must enter 192.168.1.1 in the line.
If LAN protection is completely absent,then it can become the main and main source of danger. A large number of modern hackers can use a special program called sniffer to determine the available unprotected connections. Burglars can quickly and easily intercept personal identification data that they receive from a variety of services.
When on a home or office computerThe wireless network has an unprotected connection, then users should exercise extreme caution. The content that is in the shared folders can be used by many other users. This is because there is no protection for the computer and local network. Experts advise all users and managers of large organizations to create a home group that will be protected by a complex password.
Over the past few years, the most popular have been using several ways that will help protect your computer from illegal hacking:
Network protection by these measures does not providecomplete security for users. Hackers can quickly determine the name of the network if they use the adapter. Using a modified driver, you can make a switch to a special monitoring mode. Programs called sniffer help you cope with the task.
Crackers will monitor the computernetwork until it is not connected to the user or client. Then, by manipulating the packet data, you can eliminate the client from the network. During the reconnection of the client, attackers can see the name of the network that is being used.
This process may seem difficult for many people, but in practice this is completely wrong. The whole procedure will not take more than five minutes.
Now special demand and popularity amongcrackers use a package of programs called Aircrack-ng. Cybermasters use it to quickly crack wireless network adapters. The presented program besides the sniffer includes a special application that allows you to load and modify all the necessary drivers on the adapter.
The program also provides an opportunity forrestore the WEP key. Today, there are a large number of methods that allow you to quickly and easily hack a computer network. But a client or a user of a personal computer can protect its own device on which the program will be installed to protect the network. It has a whole package of applications that protect the computer from unauthorized hacking.
To protect the device from scammers,you need to find the latest firmware that supports new encryption methods. In special programs for the protection of a personal computer already have all the necessary firmware for data encryption. When the user does not perform the update, the wireless network adapter may be at risk.
Public institutions provide freeaccess to the wireless network. They become an attractive place where cyber-fraudsters gather. Through them, a lot of information is passed, which is later used as a tool for hacking accounts or bank accounts. In cafes, hotels or many other public places you can find free access points.
But not only cyber-crooks can learn passwords andother important information. Other users who connect to this network will be able to intercept personal data of a person. Often, accounts are monitored on a variety of sites.
Protection of the Internet and cookies isa necessary measure for encryption of input information. Today there are a large number of methods of attack, which are very simple. They can use even a novice hacker or a competent user. The extension called Firesheep is used in many modern browsers. This application allows you to automatically find and read accounts of other users.
Protection of access to the network is a mandatory measure,which every user of a personal computer must take. When the router is protected with a strong password and using WPA2 encryption, no danger from hackers will be threatened by the computer and information. It is not recommended to share your password with friends and acquaintances from the wireless network. Their gadgets and mobile devices can be infected with malware.
Recently, new routers were introduced,which provide for the presence of a guest mode. Its main advantage is that the router will create a separate network with its own password. This is the best protection of networks, because the home group will not be used in this case.
