The importance of cybersecurity, also at home

As mentioned in recent articles, new technologies, apart from making life more comfortable for many people, have also favored the emergence of new risks. The case at hand is, once again, cybersecurity .

The computer risks to which SMEs are exposed advise hiring cybersecurity insurance. But what about computer security at home? In the same way that computers are vital for companies, today they are also vital for a large number of families: payment of bills, contracting of services, online purchases, etc. Therefore, in order to be well protected, we must know what threats we may have to face .

Below is a list of 7 computer problems whose knowledge can help prevent them.

Cybersecurity against the following threats

Computer viruses

Perhaps this is the problem best known to the general public. It is a code that infects an executable program and spreads by copying itself and infecting other programs. Therefore, for a virus to start working, it requires a person to activate that infected program.

The most effective way to protect yourself is by having the antivirus updated and avoiding opening any untrusted program.

Worms

Very similar to computer viruses, with the difference that they do not need any human to activate them, since they are able to copy themselves and spread over the network through, for example, the address book of contacts.

They usually cause more or less serious performance problems, since they use the resources available to the system, such as memory, network bandwidth, servers, etc.

To avoid worms, apart from having an updated antivirus, it is also advisable to be cautious with file-sharing networks.

Trojans

They are called like this because their way of acting is reminiscent of the history of the Trojan horse. They come camouflaged when programs that appear to be legal are downloaded, and while this threat does not cause harm to the computer, nor does it spread, it allows hackers to control the computer.

Once again, the best protection is caution: download only trusted programs and doubt what you put for free.

Keylogger

Another fairly famous threat. It is usually accompanied by a virus or Trojan and its function is to record the keystrokes that are made. In this way, the information is registered in some type of file and can be sent over the internet.

Rootkit

A rootkit is a program designed to provide hackers with administrative access to the computer without our knowledge. Although they cannot spread automatically (unlike viruses), they can be installed in multiple ways, such as through commercial security products or third-party application extensions.

The best way to protect yourself against these kinds of problems is to use updated antivirus and firewall protection.

DDoS attack

More business-oriented, a distributed denial of service (DDoS) attack is a computer security problem that is carried out by generating a large flow of information to the same destination point. Typically, large numbers of bots are used to produce and send such information. As a result, it is used to collapse the websites of the target companies or entities due to the large consumption of bandwidth they cause.

Exploits

Exploits are programs that contain data or code that take advantage of vulnerabilities in applications installed on the computer. Thus, these types of programs use the security breaches that may appear when developing computer programs, caused, for example, by errors during the development process. For this same reason, it is difficult for users to know that their computers have been infected by exploits.

In summary, there are multiple threats that can put our private data at risk. However, good computer protection , as well as caution when surfing the net, can be good tools to reduce the risks that we may suffer .
