Who is the secure personal Cloud Storage provider?

Cloud Storage users are increasing day by day along with numerous service providers. You might have been using them. Have you ever thought of their security? Go through this article to know how secure your cloud storage providers are.

Google Drive

When you open Drive you can observe the prefix 'https' in url bar. This indicates that the site is using a Secure Socket Layer(SSL), where the entire data of users is transferred in an encrypted form. Also they use trusted certificates to block middle-man attacks. One worst thing is that, your data in Google's servers is stored in an un-encrypted form. Google has an explanation for this, it is done so that users can preview their documents or data. But the unknown reason is, Google analyzes your files in an order to serve up target advertising. Google' privacy policy states "when you upload your content to our service, you give Google a worldwide licence to use, host, store, reproduce, modify, create derivatives etc. This indicates that Google can freely use our entire data and publish it in a desired way. Also, Google Drives offers a two-step authentication for accessing Drive, where user has to enter a delivered code to their mobile.

Microsoft Sky Drive

Sky Drive also uses an SSL certificate to transfer data for users to their data centers. Similar to Google, Sky Drive also doesn't encrypt the data at their servers which allow users to preview their files. Even Sky Drive provides a two-step verification and its is done through an alternate email address. You should remember that Microsoft doesn't provide any documentation on security protocols to secure or data. Their privacy policy states "You understand that Microsoft may need and you hereby grant Microsoft the right to use, modify, adapt, reproduce, distribute and display content posted on service solely to the extent necessary to provide the service." Thereby Microsoft promises that our information will only be used to enhance quality of service.


Mega cloud logo
Mega is referred as the most secure cloud service provider. AES-128 is used to encrypt users' data before transferring to their servers. Since it uses SSL, an extra layer of encryption is added during transfer and the entire information is stored on their servers along with a 'master key' which is in turn encrypted with hash of user's password. This facilitates extra security to your information ie even the data was stolen illegally, hacker should put a brute work to know the password, before even knowing the key to decrypt. This service uses RSA-2048, an asymmetric encryption to share secret files between users. Mega keeps redundant copies of your data for physical security. So, they'll never use your data for advertising like Google.


Box cloud logo
Another popular cloud service provider 'Box' offers a 5 GB free data storage for sharing documents, tracking comments and edits. This box uses high grade SSL certificate during data transfers and encrypt them using a 256-bit AES. These encrypted keys on their servers are rotated frequently and box uses data centers which are 'SSAE 16 Typewell' issued. Box completely differs from other providers by providing the ability of audit trails for admins ie administrators of folders can generate reports for tracking username, IP, emails for all changes made. Their privacy policy is "We'll not give, rent, sell, share or trade any of your personal information or any data that you store using our services to any third party except as outlined in this policy or with your consent." So, the exception is, in case of legal requirements or user's safety.


Drop box logo
Dropbox is also a well known and mostly used cloud storage service. Like all the above providers Dropbox also uses a SSL certificate for transferring data. But this Dropbox uses Amazon S3 servers, which are well known for their safety and high end protection level. Those S3 servers have robust security protocols, offer SSL encryption throughout and sorts data in multiple localities. Dropbox two-step authentication can be through SMS or a mobile application.

So, by considering all you can choose the best and secure cloud storage service provider. In my view, Mega can be the safest provider which offers a high security to their users by allowing dual level encryption.
