Cloud storage services ( Google Drive, iCloud, OneDrive...) help users conveniently store and access data anytime, anywhere. However, if you are not confidential, your personal data can be leaked or stolen. Here are ways to help protect information security when using cloud storage services.
Set a strong password and activate two-factor authentication
Passwords are the first protective layer for your data, so place a strong password, combining special letters, connotations, numbers and characters. In addition, you should turn on two-factor authentication (2FA). When enabled, the system will send an OTP to your phone every time you log in. Thanks to that, even if someone knows the password, they cannot access their account without a authentication code.
steps to encrypt important data before uploading
If you store sensitive documents such as contracts and personal documents, encrypt the file using software such as 7-Zip, WinRAR or VeraCrypt before uploading it. Thus, even if the file is leaked, others cannot read the content without a decoding password.
Control sharing and access rights
When you share documents, you should only send them to those who really need to see them. If they don't need you to edit your content, choose view only mode to ensure safety. After a while, don't forget to check the shared links and delete access rights of those who are no longer necessary.
Monitor and check login activities
Regularly check your login history to detect any unusual activity. If you see a strange login from a strange device or an unfamiliar IP address, change your password immediately.
Backup important data in many places
Do not rely on just one platform. You should save a copy of the data to an external hard drive or a secondary cloud service to avoid losing it if your account is locked or the system has a problem.
