Practical advice to ensure the security of your IT systems

CHOOSE YOUR PASSWORDS CAREFULLY

Entering a password that allows you to authenticate to access your computer, tablet or mobile phone is a daily security gesture.

Choosing a password that is difficult to detect by a third party or by computer hacking is therefore an effective bulwark to protect personal data against fraudulent intrusions comp tia security.

How to choose the right password?

Set passwords of at least 12 characters

Mixing upper case, lower case, numbers and special characters

Not related to you like your name, date or place of birth

Not forming words in the dictionary

Some additional recommendations

Do not use the same password for everything, in particular to access your online banking and your personal or professional messaging

Beware of software that offers to store your passwords

MAINTAIN YOUR DIGITAL DEVICES REGULARLY

By regularly updating the software of your digital devices

In each operating system (Android, MacOS, Linux, Windows, etc.), software or application, vulnerabilities exist. Once discovered, they are corrected by the editors who then offer users security updates.

Knowing that many users do not perform these updates, attackers exploit these vulnerabilities to complete their operations long after they are discovered or even corrected. It is therefore  necessary to carry out regular software updates.

How to do ?

Configure your software to automatically install security updates whenever possible

Or download the available security patches using only the official publisher websites

Routinely performing backups

Perform regular backups (daily or weekly for example)

How to do?

Cloud backup

Use external media such as an external hard drive, CD, or DVD to back up your data.

The larger and more critical the company data, the more relevant it will be to back up locally or at a service provider. But whether on site or in the Cloud, it is imperative to test the process very regularly and to check the quality of the data saved to check that they are not altered and that they are 100% recoverable in the event of an incident.
