Security in the Internet. Information security on the Internet

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

Dangers lying in wait for us in the network

In short, there are two main possibilities for 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 even secretly from its owner, starts sending 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?

No ordinary user thinks that his computer is not needed by anyone. 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 your computer, instead of a standard desktop, there will be some funny pictures. Now they are doing everything possible to ensure that the owner of the PC 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 try 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 purse, 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, conduct a DDoS attack, even on powerful state servers. From the simplest, but also bringing money: block the operating system and 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 it is, hackers use a number of ways, and users in vain think that by simply installing an antivirus, they have 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. Thanks to various psychological tricks, tricks and gullibility 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 proven sources, there are always security holes. 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 checked site and - once - your device is infected.
4. The fourth method has become very popular recently. This is phishing when fake sites are created. And you instead of the page of your bank are on his fake copy. About what can be further, we will not speak, you yourself will guess.

Initial protection of the user's computer

Ideally, having bought a PC, the user must perform a 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.

1. Despite the fact that Windows has a built-in firewall, it is recommended to install a more reliable one, since the existing one is far from the best. Choose paid or free, based on their ratings.
2. The next step is installing antispyware and antivirus software. You need to update it immediately and configure it for automatic updating. 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

Now a little information on how to ensure the safety of work on the Internet. After completing the steps outlined in the previous section, continue to keep in mind daily protection.

1. Delete immediately all messages of suspicious content, do not try to open files from unknown sources. Ignore all offers of easy earnings, do not send out your passwords to anyone, do not skip the suspicious links.
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, be careful and careful. The same applies to the use of proxy servers. It is advisable not to conduct any banking or 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 it is unlimited. If it has increased significantly without a particular 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 one must not forget about them for a minute.

Some more safety lessons on the Internet

Now let us briefly talk about some of the precautions. If a letter came from your bank with a password check, do not think of sending it to them. Banks never make such requests. All email programs have a spam filter. Trust him. Having received 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 antivirus - from one manufacturer, firewall - from another, and antispyware program - from the third.
Give preference to paid versions. Since Opera and Internet Explorer are the most common browsers, there is more for them and viruses. Use alternatives: Apple Safari, Google Chrome and Mozilla Firefox. Do not use unlicensed software, as it may initially be installed spyware. If you shop in online stores, then use only proven options. The same applies to any other online service. Fulfill all these requirements, and then security in the Internet will be more or less guaranteed.

Children and the Internet

And if before they basically played games, even without going online, now everything is completely different, and you yourself all know. Therefore, there was a new task - to ensure the safety of children in the Internet. This is quite difficult, since the World Wide Web initially develops completely uncontrollably. In it there is a lot of information, access to which children should not be. In addition, they need to be taught how not to "catch" viruses and Trojans. Who will help them with this, if not adults. In addition, information security in the Internet is very important, since children are completely inexperienced users. They can easily fall for the bait of an experienced fraudster or intruder.

How to teach children how to use the Internet correctly

The very first advice is that the first sessions on the network the child should spend with someone from adults. It is desirable to use programs such as "Parental Control" to monitor all the actions of children on the Internet. It is necessary to limit the independent use of mail and chat rooms, because it can be even dangerous. Since there, for example, pedophiles can seek victims.
