Security in the Internet. Information security on the Internet

Security on the Internet is a very important issuethis time. And it concerns everyone, from children to pensioners. It is becoming more and more relevant in connection with the massive arrival of users on the Internet, almost, and even completely, not prepared for threats, waiting for them. Therefore, this article will be devoted to such issue as security on the Internet. After all, not one user suffers, but many others, united in one global structure.

The dangers that await us in the network

To put it briefly, there are two mainThe possibilities of how your computer can become a victim. The first is you yourself, traveling on different sites or installing software from untested sources, and sometimes with proven ones, infect your computer. Secondly, it is also possible that intruders intentionally, with the help of, for example, Trojans or viruses, make your device a source of danger.

As a result of all this, the computer, sometimes evensecretly from its owner, begins to send spam, participates in DDoS-attacks on various sites, steals passwords. It also happens that the provider has to forcefully disconnect such a device from the global network. It turns out that if the user is not aware of what constitutes the basis of security on the Internet, it will be hard for him.

Why do cybercriminals need access to a user's computer

The common user simply does not think that hisno one needs a computer. Earlier hackers often wrote viruses just for the sake of interest, now it is almost always done with commercial benefits. About 20 years ago, an attacker was enjoying the fact that he could simply format the hard drive. Or to make it so that when you turn on the computer, instead of a standard desktop, there will be some funny pictures. Now they are doing everything possible to ensure that the PC owner as long as possible does not know that his device is infected and secretly performs additional functions from him.

Why is all this done? In addition, as mentioned above, hackers are trying to access your e-mails, wallets, accounts in social networks, forums. It happens so, for example, that you go to bed with 20 000 rubles on an electronic wallet, and in the morning you receive an SMS message that there is already no money on it. And from the mail, all your contacts, and not only receive spam emails, or even trojans. Hackers can combine a lot of infected computers into a single powerful network, carry out a DDoS attack, even on powerful state servers. From the simplest, but also bringing money: they will block the operation of the operating system and will require money to fix the problem. And, by the way, money will be taken, but the computer will be blocked. So security on the Internet should be the foundation of your work in it.

How do intruders get into the computer? detailed information

In order to crack the protection of the PC, even if itthere are, hackers use a number of ways, and users in vain think that by simply installing an antivirus, they got rid of the danger, for example, to pick up a malicious program. Therefore, before you look for information on how to properly comply with security on the Internet, you need to understand, and where are the viruses and Trojans. Now we list the main ways of their penetration and methods of theft of various information.

1. The first method is called social engineering. Due to various psychological tricks, tricks and credulity of users, hackers send you a completely innocuous file or letter, and you yourself launch a Trojan in it. Or, at the request of the alleged administration of the service, you issue all your passwords and appearances.
2. The second method - offers a variety of free software, pirated discs, where many viruses, trojans and similar nasty things are hidden.
3. In the software, including the most reliable provensources, there are always holes in security. This also applies to operating systems. Here, attackers carefully and follow such moments, try not to miss them, but to use for their own purposes. Go to any page a hundred times a proven site and - once - your device is infected.
4. The fourth method was particularly popular inLately. This is phishing when fake sites are created. And you instead of the page of your bank are on his counterfeit copy. About what can be further, we will not speak, you yourself will guess.

Initial protection of the user's computer

Ideally, by purchasing a PC, the user must performa number of operations before rushing to plow through the endless expanses of the network. Now we will introduce some of the very first lessons of security on the Internet.

2. The next step is the installation of antispyware andantivirus software. You need to update it immediately and configure it for automatic updates. Also, it should run automatically, along with the OS. And constantly, in the background, work. And be sure to check any installed program.
3. As soon as updates appear for Internet Explorer and other browsers you use, immediately download and install them.
4. Disable all unused services on your device, this will reduce the chances for hackers to access it.

Further safety lessons

2. Use only complex passwords, consisting of a complex set of numbers, letters and symbols. For each case, assign your own, original.
3. When leaving the network from public places, becareful and careful. The same applies to the use of proxy servers. It is advisable not to conduct any banking and other similar operations from such places.
4. Prefer to work with payment systems through their own applications, and not through the site. It's much safer.
5. It is not advisable to visit adult sites or similar resources. Chances are high to pick up the Trojan.
6. Watch for Internet traffic, even if itunlimited. If it has increased significantly without a special reason, this may be a sign of the activity of the virus. If you comply with these minimum security rules on the Internet, then avoid many problems. Of course, this is not all. There are so many dangers that you can not forget about them for a minute.

Some more safety lessons on the Internet

Now let us briefly discuss some more measuresprecautions. If a letter came from your bank with a password check, do not think of sending it to the bank. Banks never make such requests. All email programs have a spam filter. Trust him. If you receive a letter about winning a million rubles or an inheritance of five million dollars, delete them immediately. We recommend to install complex protection. It is more reliable than an antivirus - from one manufacturer, a firewall - from another, and an antispyware program from the third.

Prefer paid versions. Since Opera and Internet Explorer are the most common browsers, for them and viruses exist the most. Use alternatives: Apple Safari, Google Chrome, and Mozilla Firefox. Do not use unlicensed software, as spyware can be initially installed in it. If you shop at online stores, use only proven options. The same applies to any other online service. Follow all these requirements, and then security on the Internet will be more or less guaranteed.
