Internet security is a set of methods to ensure the safety of data and information stored in a system connected to the world wide web. Today it has become an extremely relevant topic all over the world. People who regularly visit the Internet should be aware of the problems that may arise while doing this.
Using antivirus alone is not enough, you should definitely learn about other ways to keep your computer secure.
One of the common ways to ensure the security of information on the Internet is to:
• Data encryption. This is nothing more than the transformation of the original data into a set of unreadable information that can only be decrypted using a certain method.
• Use of passwords. Passwords are used to prevent unauthorized access to information, so that the entire computer, with all its contents, is under its protection. Choosing a password for your computer should be such that it is not easy for other people to guess it.
There are quite a few methods for ensuring internet security. Some of them are presented below:
1. Using Firewall. Firewall is software that filters unauthorized attempts to access your computer and also prevents unauthorized outgoing connections. It must be properly configured to effectively secure the system.
2. Data backups. Data should be backed up regularly, at least, as a last resort, those that cannot be restored later. In case the hard drive suddenly becomes unusable, or the operating system crashes due to a virus attack, a backup copy will help minimize unpleasant consequences.
3. Prevention of virus attacks. If you often download various files from the Internet, then there is a high probability of infecting your computer with viruses, Trojans, worms, etc. Viruses are small programs that install themselves and run every time you launch an application infected with them. This type of malware can cause many different troubles. Viruses can replicate themselves, and also contain a hidden function that affects the system files of the computer and leads, in the worst case, to the collapse of the operating system and the loss of all data. You can protect yourself from viruses using numerous antivirus applications that are designed to search for and destroy found malware of this type.
4. Malicious links. You can also protect your computer from virus attacks by passing by dubious links that lead to unverified resources and by avoiding reading suspicious emails. It is worth remembering, however, that in some cases, links may be loaded unexpectedly for the user and without his consent. To reduce the exclusion of such situations, do not visit suspicious sites.
5. Routers. Some routers prevent external connections to the computer and allow outbound connections, which eliminates some potential security threats to the system.
6. Interfering with SpyWare Programs. SpyWare is software that is launched along with other applications and, without the user’s knowledge, collects the necessary information, and subsequently sends it to the developer of this program via the Internet. Such programs are also known as spyware.
There is also a program called ad-ware that works like a spyware. But she is engaged in loading unnecessary ads while surfing the Internet, which reduces system performance and slows down the computer and the network.
Internet security in general:
You should unplug your computer when not in use. Certain Internet connections are created as soon as the system starts up. This should be avoided, because this way, you give computer spyware an extra chance to steal your data, and once again, by disconnecting your computer from the network, you will prevent many attempts of illegal access to your system. Using only one antivirus program, Firewall, etc. you will not ensure your system is completely safe from intrusion of viruses. Your personal care is also required when using the Internet. Remember – you should beware of unverified sites and unverified links, and you should also not download and run dubious files from the network on your computer. All this together will make your system as safe as possible from Internet threats of any kind.
