What is Network Security?

About how correctly it is necessary to pass the roadway of the street, everyone is taught from childhood. This knowledge is then fixed in the school. And in many children's TV programs this issue is actively considered. In the necessity of this, no one doubts, because knowledge and observance of traffic rules is a guarantee of preservation of health and even life. But modern realities are such that, together with the above rules, you can begin to learn the basics of network security.

The computer and laptop have become just as familiar attributes of a comfortable apartment as an automatic washing machine. If before the cost of computers was so high that only a few could afford to buy a home electronic assistant, but now the situation has radically changed. Hardware prices are falling every day, and providers are offering ever more attractive tariff plans. Therefore, there is nothing surprising in that people who do not understand the meaning of information security on the Internet are connected to the Network . Alas, they themselves suffer from this, becoming victims of virtual scammers.

Network security is a complex of measures, the main task of which is to prevent the theft of confidential data and any other violation of the normal operation of the computer due to unauthorized access to it from the outside. Due to the constant increase in the speed of access to the global network, the conditional boundaries between computers are increasingly erased, and therefore completely new ways of cheating gullible users began to appear. Gradually, computer viruses that have already become familiar , the work of which is based on vulnerabilities in the software used, fade into the background. Therefore, now network security can not be limited to just installing antivirus protection, as it was before. A set of measures is needed. The maximum effectiveness of protection is possible only with the use of software security and common sense.

Software network security includes:

- Use of the anti-virus application. It is recommended to pay attention to the well-known products of the Internet Security group, as they have more opportunities;

- use the update function of the anti-virus database and the operating system itself;

- If the firewall is not part of the anti-virus application, then it must be installed. The solution built into the system is not effective enough;

- The connection must be properly configured. If there is no local network, access to the disks must be disabled;

- Do not save access passwords to important sites using the browser mechanism.

In addition, network security involves the care of the user. All access codes must be typed manually, and the copy-paste function should be ignored. This is especially important for operations related to finance.

Suspicious emails that come to an email need to be deleted without even opening them.

With the mobile phone number, you should be careful not to report it without emergency. It is acceptable to use it only for initial registration on some sites and programs: e-commerce banking sites, social networks, skype, etc. If some third-party resource asks for your number to confirm something, you need to understand the potential threat of such disclosure. Being in the global network, it is very useful to forget about the presence of a mobile phone for a while - there is only a stationary one, so its number can be reported.

It is necessary to read anti-virus protection messages and properly respond - an affirmative answer to everything reduces the level of security by more than 2 times.
