Online security: 4 key principles

Technologies develop. Ever more devices are connected. How to ensure that your data is always protected? 4 key principles

1. You are your best protection

Security technologies evolve but cybercriminals quickly learn to circumvent them. Your best protection against fraud is your common sense. You can identify most attacks yourself, in particular those which affect you directly, such as ransomware or phishing.

2. Choose your password well

You will certainly already be aware that it is essential to protect all your devices and online accounts by means of a password. To increase your protection we also advise you to use two-stage authentication.

A strong and unique password

To be strong it must include as many different characters as possible to make it more difficult to hack. Unique, as you need a specific password for each application/account/device.

Quick tip: use passphrases.

They are longer than passwords and, consequently, safer but also easier to remember! Read our 3 tips for creating an easy and safe passphrase.

Trouble remembering all your passwords? Use a password manager. It is software which stores them safely. You can easily find free tools with your browser. Make sure to use a safe passphrase to secure the password manager.

2-Stage authentication for greater security

Have you not heard of dual authentication? It enables you to enhance security by means of a password and a second confirmation, for instance via a code sent to your mobile phone.

3. Are your updates “updated”?

Cybercriminals are always on the outlook for the slightest weakness in your software. Editing companies, for their part, constantly improve their software to block such weaknesses. How? By offering updates. This is why it is important to ensure that your devices and applications always benefit from the latest version of their software.
Tip: activate updates automatically, it will make your life easier!

4. Save, save and save again

Even when you take all the aforementioned precautions, your computer can become infected by a virus. In that case, generally the only solution is to re-initiate your device which means that all your data will be removed. Photos, videos, personal details... If you do not want to lose them, make sure you save them regularly! How? Store them on a secured cloud or an external hard disk for example.

Check regularly that you are properly protected
