Cloud or online storage, for instance Dropbox or iCloud, are very popular. What do you have to watch out for when using such services though?
With cloud storage, data (documents, photos, films, passwords, etc.) are stored centrally at a data centre. Access to your data is generally handled via the Internet. This central storage enables you to access your data from several devices (also at the same time).
Yet with all the advantages this facility offers, you must not forget that you pass on your data to a third party.
Protect yourself by ...
- choosing a suitable cloud provider.
There may be drawbacks to using foreign, and above all non-European cloud providers, with regard to data protection.
- ensuring you are able to securely authenticate yourself.
If possible, use two factor authentication, similar to the method used with e-banking.
- applying our «6 rules for a secure password».

- only ever transmitting your data in encrypted form.
Use a service which transmits your data in encrypted form. Inside a browser, this is for instance the case if «https://» and a lock symbol are displayed at the beginning of the address line.
- only ever storing your data in encrypted form.
You are generally unable to check that your cloud provider encrypts your data correctly. Encrypt and decrypt your sensitive data yourself.
- creating an additional local back-up of your data.
You are generally unable to check that your cloud provider backs up your data correctly either. For this reason, you should make absolutely sure that you create local back-ups of all your data stored in the cloud, too.
