Cyber sécurité

Cybersecurity is the art of protecting networks, devices and data from unauthorized access.

One of the best methods of protection is data encryption. With encryption, data is encrypted

via a unique key needed to access the data. With strong protection, cybersecurity allows you

to have control over who has access to your data, while keeping it clean and confidential to

prevent any action aimed at accessing, stealing or corrupting your data.

A cyber attack is any malicious act which harms IT systems for economic or political

reasons.

They represent a threat for us the consumers, but mainly the organizations and

companies.

The main goal for hackers is to claim money in exchange for the stolen data.

We will see an old and a recent example of a cyberattack.

new one.

They also used social networks to enroll employees from companies to leak information.

Lapsus$ also developed an nvidia certificate signing tool. Using these signatures on their

viruses, they will be spoofed so the anti-virus won’t detect them.

The best way to combat "social engineering" is to educate employees and personal user in

general about the risk of this type of social attack.
