Network protection is a complete and necessary set of measures, which includes the organization, creation of software, as well as the adoption of physical and technical measures. Only such a complex can ensure the maximum achievement of the properties of an information resource.
Informational resources
Today it is necessary to carefully take care of the encryption of specific properties of information resources. Network protection is possible with the necessary measures. There are several main properties of the information network:
- Integrity. Programmers and specialists must fully ensure the relevance and veracity of information that will not contradict the sources. Materials are protected from any destruction from outside and unauthorized changes.
- Full confidentiality. Maximum security is provided for the necessary information, which may be subject to unauthorized access by scammers.
- Availability. Network protection is carried out in a set of measures that will help provide all the necessary capabilities. They help users access stored and processed information.
- Authenticity. There is a necessary guarantee of the authenticity of subjects and objects that have access to certain information.
Protecting a 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 are automatically connected to the network. Protecting computer networks will help prevent unplanned traffic consumption. But in some cases, the situation may worsen. Sometimes users use an insecure connection to download 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 endangers himself. You need to go into the router interface and change the network access data. The address of the router is indicated in the instructions that are issued at the time of purchase of such a device. If not, you can determine the IP address using your own network device. To do this, a browser window opens where you must enter the address 192.168.1.1 in the line.
Why is it necessary to secure a computer network?
If the protection of the local network is completely absent, then it can become the main and main source of danger. A large number of modern hackers can use special programs called sniffer to identify existing insecure connections. Hackers can quickly and easily intercept the personal identification data they receive from a variety of services.
When a wireless network has an insecure connection on a home or office computer, users should exercise extreme caution. Content located in shared folders can be used by many other users. This is because there is no protection for the computer and local network. Specialists advise all users and managers of large organizations to create a home team that will be protected by a complex password.
Hacking
Over the past few years, several methods have become most popular that will protect your computer from illegal hacking:
- MAC address filtering.
- Hiding the SSID, i.e. classifying the network name.
Protecting the network with these measures does not provide complete security for users. Hackers can quickly identify the network name if they use the adapter. Using a modified driver, you can switch to a special monitoring mode. Programs called sniffer will help to cope with the task.
Hackers will monitor the computer network until a user or client is connected to it. Further, by manipulating packet data, you can eliminate the client from the network. During client reconnection, crackers can see the name of the network that is being used.
This process may seem complicated to many people, but in practice it is completely different. The whole procedure does not take more than five minutes.
Computer network hacking program
Nowadays, a software package called Aircrack-ng is in particular demand and popularity among crackers. Cyber fraudsters use it to quickly crack wireless network adapters. The presented program, in addition to the sniffer, includes a special application that allows you to download and modify all the necessary drivers on the adapter.
The program also provides the ability to restore the WEP key. Today there are a large number of methods that allow you to quickly and easily crack a computer network. But a client or user of a personal computer can protect their own device on which the program for protecting the network will be installed. It has a whole package of applications that protect the computer from unauthorized hacking by hackers.
To protect the device from scammers, you need to find the latest firmware that supports new encryption methods. In special programs for protecting a personal computer, all the necessary firmware for data encryption is already available. When the user does not perform updates, the wireless adapter may be in danger.
Public access point
Public places provide free access to a wireless network. They become an attractive place where cyber fraudsters gather. A large amount of information passes through them , which is subsequently 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 fraudsters can learn passwords and other important information. Other users who connect to this network will be able to intercept the person’s personal data. Often, monitoring accounts on a variety of sites.
Protecting the Internet and cookies is a necessary measure to encrypt the entered information. Today there are a large number of attack methods that are very simple. Even a novice hacker or a competent user can use them. An extension called Firesheep is used in many modern browsers. This application allows you to automatically find and read the accounts of other users.
How to protect your home network?
Network access protection 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, the computer and information will no longer be at risk from hackers. It is not recommended to disclose the password from the wireless network to friends and acquaintances. Their gadgets and mobile devices may be infected by malware.
Recently, new routers have been introduced that include guest mode. Its main advantage is that the router will create a separate network with its own password. This is the best protection for networks, because the homegroup will not be used in this case.
