Beware of connected objects
Most objects we connect to a computer present a security risk.
A malicious mind can easily install spyware to infiltrate a system. USB keys, smartphones, electronic cigarettes can host these malwares that are patiently waiting to go into action. You must be very vigilant with this type of hardware and absolutely ban keys found on the ground, lent by a third party or given as gifts.
If you use these keys to store personal or confidential, private or professional data, you run the risk of having them spied on and stolen remotely. Connecting a device of unknown origin to your computer is very risky because it can create a doorway to the data it contains.
Similarly, be aware that storing data on a USB memory stick can be dangerous if stolen, lost or loaned. Even if deleted, this data could still be recoverable.
Let's also take the time to talk about the separation of uses.
Today, the boundary between private and professional life is blurring, which poses security issues. Indeed, the computer travels, more and more often from work to home where the whole family can use it.
It is recommended to create several user accounts, each with well-set up rights, a strong and different password, depending on the uses. It is important to also separate professional and private messaging. The idea is to separate private and professional life as much as possible for the benefit of all.
In a professional environment, if you have the authorization to do so, prefer to create a personal user account to protect your privacy at work. We tend to mix uses to make life easier, but this is to underestimate the dangers to which personal data is exposed, like a colleague who is a little too curious.
