How a Computer Expert can Help to Prevent or Report Cyber Attacks

Businesses were forced to advise their employees to telecommute as a result of the outbreak of the pandemic, and many of them still have part or all of their staff out of the office.

Although the coronavirus crisis has pushed the self-employed and SMEs to accelerate the digital transformation that they so badly needed, the truth is that this increase in the use of new technologies has also brought some negative consequences.

According to figures published by the Government, the State Security Forces and Bodies registered 287,963 allegedly criminal acts related to information and communication technologies in 2020, 32% more than in 2019. 

This increase in cybercrime largely affects smaller businesses that do not have as many security measures as large companies. They can suffer from theft of information or business bank accounts by hackers and even the competition to misuse their employees’ data and technological tools.

Faced with these new risks, one of the professions that have become increasingly relevant is computer expertise, a trade that, despite being booming, is still largely unknown to companies and the general public. 

The function of these professionals is the prevention and provision of evidence to fight against all kinds of crimes committed through technology: from cases of espionage or revealing secrets; crimes against intellectual property or interference with the privacy of individuals; even illegal access to documents or files of a business; justification of dismissals for inappropriate use of technology; dissemination of private data of a company; and in general, any crime committed through automated means. 

The help that these professionals provide to the self-employed and SMEs can be twofold: small businesses can find out if they are exposed to or have suffered a cyberattack, and, in addition, they can also report it with the evidence collected by the expert.

He explains to this newspaper what his profession consists of and what help he can provide to the self-employed and small businesses.
