In recent months, our relationship with digital technology has intensified, both personally and professionally. From online shopping platforms to government services, including social media, we manage a large number of accounts, profiles and avatars on a daily basis to access online services that offer to simplify our lives. Faced with this multitude of portals, many express the feeling of being overwhelmed by the different identifiers and passwords to remember.

Do we adopt safe reflexes in all our online actions? On a daily basis, the temptation to go there "quickly" is sometimes strong, but also involves very real dangers.

Is your password secure?

Let's take a facet of cybersecurity that concerns us all: online passwords.

A password is a series of characters (letters, numbers and symbols) used as a means of authentication to prove one's identity. Formerly used by the military and spies to recognize each other in the event of low or no visibility, the term "password" has also become more widely used in the literature. We all know the legendary password from the Thousand and One Nights tale “Ali Baba and the Forty Thieves”: “Open sesame! ".

The news of recent years has often shown us that specialists in malicious computer techniques, or cyber hackers, multiply and steal quantities of sensitive data, starting with passwords.

Do you know the vulnerability of the password used to connect to your email account, to your organization's VPN, or to access your bank account? In this regard, the perpetrators of threats can resort to "brute force" (from English brute force) to crack a password. Basically, this computer method consists of testing, one by one, all the possible combinations. Obviously, the more complex the combination, the longer the decryption time will be. And vice versa!

As a guide, here is the time required today to crack a password with this method, depending on the number and type of characters used:

Time required to crack a password

This is why it would be relevant to propose today to Ali Baba to optimize his formula in the light of good practices in cybersecurity: $é$am3 0uvr3 * to1 would allow him to sleep soundly about his virtual cave!

School and cybersecurity

In an increasingly connected school environment where digital levers allow a judicious integration of ICTs, students, teachers and managers are living the challenge of developing a dynamic and equally secure creative posture. 

To learn more about online authentication and other cybersecurity issues in schools, CADRE21's “Educating for cybersecurity” training is available here.

Not to be missed, the Carrefour education's cybersecurity guide, which offers resources for young people to understand the threats that exist online so that they can avoid them.
