Computer network is a system of connected computers and peripherals, which allows them to work collaboratively, share resources, be controlled with a modified central part, and also allows them to be protected or limited as a group. Security software, in a broad sense, is any software that helps keep a system or network safe from risk or danger, or to keep data secure. Computer network security software is a program that aims to protect the network and its data. different ways and from various threats.
Often, many users think that computer network security software is standalone program or a package of products designed solely for safety. But, such thinking could be ignored by a very important type of security software. The missing ingredient will have security patches issued by operating system manufacturers. They are focused on both security and their software, so although they do make updates to the software and that means they still rely on dedicated network security software to run the computer.
The products that most often come to mind as network security software are those that start with “anti”. It includes anti-virus software, anti-malware is short for “malware”, and anti-spyware. At different manufacturers the three names are used slightly differently, but in general, the software is designed to catch and shut down or prevent the intrusion of viruses, worms, Trojan horses, backdoors, rootkits, spyware, and sometimes botnets, spam, and phishing attacks.
Generally speaking, security includes data security, and therefore computer network security software includes software that automatically performs backup data. For even more security, backups can be made on site. Backup software can be set to frequency backups and located on the drive or server being backed up. Encryption of data can also contribute to the security of data, so we do not consider them in this category yet.
In the field of protecting a system from unwanted intrusions, there are at least four roles that computer network security software can perform. One thing to think about is a properly configured web browser as a security program, because the handling of cookies, passwords, downloads, attack targets, and web content also contributes to system security. Secondly, the firewall software on the computer, router, server, or all three, help to prevent PC infection. You can go even further with software network scanning, intrusion detection software, or log on to a system that only grants network access to pre-approved individuals.

Internet security is a very important issue of today. And it concerns everyone, from children to pensioners. It is becoming more and more relevant due to the massive arrival of users on the Internet, almost, if not completely unprepared for the threats that await them. Therefore, this article will be devoted to such an issue as security on the Internet. After all, not one user suffers, but many others, united in one global structure.
The dangers that lie in wait for us online
In short, there are two main possibilities for how your computer can become a victim. The first is that you yourself, wandering through various sites or installing software from unverified sources, and sometimes from verified ones, infect your computer. Secondly, a situation is also possible when attackers deliberately, using, 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, and steals passwords. It also happens that the provider is forced to forcibly disconnect such a device from it. It turns out that if the user is not aware of what the basics of security on the Internet are, he will have a hard time.
Why do attackers need access to the user's computer
in vain ordinary user thinks that nobody needs his computer. It used to be that hackers often wrote viruses just for fun, but now it's almost always done for commercial gain. About 20 years ago, an attacker enjoyed the fact that he could simply format HDD. Or make it so that when you turn on the computer, instead of the standard desktop, some cool pictures will appear. Now they are doing everything possible so that the PC owner does not know for as long as possible that his device is infected and secretly performs additional functions.
What is all this for? In addition, as mentioned above, hackers try to gain access to your emails, wallets, accounts in in social networks, forums. It happens, for example, that you go to bed with 20,000 rubles for e-wallet, and in the morning you receive an SMS message stating that there is no more money on it. And from the mail all your contacts, and not only, receive spam letters, and even trojans. Hackers can combine many infected computers into a single powerful network, carry out a DDoS attack even on powerful government servers. From the simplest, but also bringing money: they will block the operation of the operating system and demand money for fixing the problem. And, by the way, the money will be taken, but the computer will be left blocked. So security on the Internet should be the basis of your work on it.
How do intruders get into a computer? detailed information
In order to crack PC protection, even if it exists, hackers use whole line ways, and users needlessly think that by simply installing an antivirus, they got rid of the danger, for example, to pick up malware. Therefore, before looking for information on how to properly maintain security on the Internet, you need to understand where viruses and trojans come from. Now we will list the main ways of their penetration and methods of stealing various information.
- The first method is called Thanks to various psychological tricks, tricks and gullibility of users, hackers send you a completely harmless file or letter, and you yourself launch a Trojan in it. Or, at the request of the alleged administration of the service, you give out all your passwords and appearances.
- The second method - various free software is offered, pirated disks, where a lot of viruses, trojans and the like are hidden.
- Security holes are constantly appearing in software, including those from the most reliable trusted sources. This also applies to operating systems. Here attackers carefully and monitor such moments, try not to miss them, but use them for their own purposes. You go to some page of a site that has been checked a hundred times and - once - your device is infected.
- The fourth method has received special distribution recently. This is phishing when fake websites are created. And instead of the page of your bank, you find yourself on its fake copy. We won’t talk about what could be next, you can guess for yourself.

All 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 installing comprehensive protection. It is more reliable than antivirus - from one manufacturer, firewall - from another, and anti spyware- from the third.
Give preference to paid versions. Since Opera and Internet Explorer- the most common browsers, for them and viruses there are most of all. Use alternative options: Apple Safari, Google Chrome and Mozilla Firefox. Do not use unlicensed software as it may have spyware installed by default. If you shop online, use only trusted 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.
