Network protection. Program for the protection of computer networks

Network protection is a complete and necessary set of activities that includes the organization, the creation of software, and 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.

Informational resources

Today it is necessary to carefully take care of encryption 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:

• Integrity. Programmers and specialists must fully ensure the relevance and truthfulness of information that will not contradict the sources. Materials are protected against any destruction from the side and unauthorized changes.
• Full confidentiality. Maximum security is provided for the necessary information, which can be subjected to unauthorized access by fraudsters.
• Availability. The protection of networks is carried out in a complex of measures that will help to provide all necessary facilities. They help users to access stored and processed information.
• Authenticity. There is a necessary maintenance of authenticity of subjects and objects which have access to the certain information.

Protecting the computer network from an intruder

If the network is not password-protected, unauthorized users can connect to the wireless connection. In most cases, they do this 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 may be aggravated. Sometimes users use an unprotected connection to start downloading illegal content.

If the owner of the personal computer has not taken any measures to protect the network from unauthorized access by third parties, then he exposes himself to danger. You need to enter the interface of the router and change the network access data. The address of the router is indicated in the instruction that is issued during 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.

Why do I need to secure the computer network?

If LAN protection is completely absent, it can become the main and main source of danger occurrence. A large number of modern hackers can use special programs 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 a wireless network on the home or office computer has an unprotected connection, 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 leaders of large organizations to create a home group that will be protected by a complex password.

Hacking

Over the past few years, the most popular have been using several methods that will protect your computer from illegal hacking:

• Filtering by MAC addresses.
• Hiding the SSID, that is, classifying the network name.

Protecting the network with these measures does not provide complete 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.

Burglars will monitor the computer network until it connects 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.

Fraudulent program for hacking a computer network

Now a special demand and popularity among the burglars is the software package 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.

Also, the program provides an opportunity to restore the WEP key. Today, there are a large number of methods that allow you to quickly and easily hack a computer network. But the client or user of the 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 scams, 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 encrypting data. When the user does not perform the update, the wireless network adapter may be in danger.

Public access point

Public institutions provide free access to the wireless network. They become an attractive place where cyber-mongers gather. Through them, a large amount of information passes , which is further 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 and other important information. Other users who connect to this network will be able to intercept personal data of a person. Often, accounts are controlled on a variety of sites.

Protection of the Internet and cookies is a necessary measure for encryption of information entered. Today there are a large number of methods of attacks, 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.

How to protect your home network?

Protection of access to the network is a mandatory measure that 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.
