Deconfinement: Specialists prepare for employees' return to offices

For almost two weeks, there has been a wave of deconfinment everywhere.

Work picks up a bit depending on the sector, and employees begin to return to the office after almost 2 months of telework. A transition that is closely followed by several cybersecurity specialists. Indeed, during this period when remote work had become a standard, there was a wave of cyber-malveillance acts, which continued to grow more and more. Hackers have never been more prolix.

This is what scares cybersecurity experts the most, who know a reality that has been doing the job for a while. Telework has exposed businesses even more. If during the containment period the computer systems of companies were constantly in danger, the deconfinement heralds for those who know how to observe, a new crisis in cybersecurity.

The danger of returning employees to companies is a prelude to the transition to remote work. A transition that was rushed and organized without any real assurances. "We had to get by and do it with the means on board. For many companies, it was a bit of a walk or a break. It's hard to blame them. "Cybersecurity expert Bastien Robert" noted. Everything was organized abruptly. Not leaving a lot of time for some companies to prepare. Indeed, "Most companies did not have an in-house tool before the pandemic began. They have therefore turned to the most popular solution, which is both easy for employees to use and works well. In this case, Zoom. explains our cybersecurity expert. Gérôme Billois, it security expert at Wavestone. This security specialist says: "Most of the telework is still done the old-fashioned way. ».

Second, the way remote work has been conducted has been likely to expose not only users of direct digital services, i.e. employees, but also their company's systems. It should be noted that for individuals, it is not as easy to understand in terms of computer discipline. If within the company there is a certain environment that allows certain rules of use in digital hygiene, once at home, it is very easy to neglect them. Orange CEO Michel Van Den Berghe recalled: "In the company, you are like a castle. But when you're at home, the level of protection is immediately much lower." "The big challenge with telecommuting is to separate the work environment from the staff environment," says Baptiste Robert. "On a company-configured computer, administrative rights are limited, which prevents anything from being installed. On a personal computer, the user has a wider scope of action, making them more vulnerable to hacking attempts," he adds. This way, creating an amalgam between the home environment and the work environment, makes it easier for cyber criminals. It is clear that the home internet connection are clearly less protected or not at all. In what context, a simple malware, would be likely to cause damage than software designed specifically to attack a more robust system. It would then be easy for cyber-prisoners to place dormant programs on the terminals used by teleworkers, the clear aim of which is to attack the company's system.

Therefore, IT teams will have to implement a whole system, in order to promote a fairly controlled return of employees within companies. For it is through them that the risk will surely come. Gérôme Billois noted in fact: "The teams in charge of protecting the computer park were a little more blind than usual. With the deconfinement, the services will have to manage a return of computers, sometimes up to several thousand, which could be exposed to just about anything and everything for weeks. ».
