Data breaches can affect anyone, and it's not just a matter of IBAN theft. The CNIL (French Data Protection Authority) has published a comprehensive guide covering all scenarios: how to detect a breach, protect your information, react to phishing or identity theft, and much more.
📌 Monitor your accounts and permissions
📌 Beware of phishing and identity theft attempts
📌 Strengthen your passwords and enable multi-factor authentication
📌 Report any anomalies promptly to your bank or via cybermalveillance.gouv.fr
I fully support these procedures: it is essential that everyone understands the importance of data security, whether in their professional or personal life.
Leave nothing to chance, this book is a must-read. 🔗
