A cloud storage is a way to keep your file saved on third parties services over the internet.


3::Encrypt files yourself
2::Appropriate management of share settings
1::Leave it to your cloud service provider

This is the correct answer. If you need to store documents on your cloud storage that you consider important to be kept in the most secure way, then the most appropriate solution is to encrypt your files. If you are the only one holding the decryption key, no one else – including the cloud provider or any possible attacker - will be able to decrypt your files and therefore read or use your personal information.

This answer is not exactly correct. Indeed, it is important to carefully check and amend, if necessary, your share settings (cloud storage services typically allow one of three settings: i) private, i.e. only you can view the files, ii) public, i.e. everyone can view the files without any restriction and iii)shared, i.e. only people you invite can view the files). However, if you need to store documents on your cloud storage that you consider important to be kept in the most secure way, then the most appropriate solution is to encrypt your files. If you are the only one holding the decryption key, no one else – including the cloud provider or any possible attacker - will be able to decrypt your files and therefore read or use your personal information.

This answer is not the correct one. Whilst cloud service providers are supposed to take data security very seriously, it is not good idea to rely only on this; there is nothing wrong with taking extra steps to ensure that your personal information is kept safe and secure. 

The correct answer in the context of this scenario is to encrypt your files yourself. If you need to store documents on your cloud storage that you consider important to be kept in the most secure way, then the most appropriate solution is to encrypt your files. If you are the only one holding the decryption key, no one else - including the cloud provider or any possible attacker- will be able to decrypt your files and therefore read or use your personal information.

Common examples are Dropbox or Amazon Cloud Drive. You have been using your personal cloud storage to backup photographs but you are considering storing documents and some may contain personal information that you would like to keep secure and private. What steps can you take to ensure that this happens?
