Symmetric encryption is typically faster than asymmetric encryption, but it is less secure since the key is shared. This means that anyone with the key can access the data, so it is important to keep the key secure. ![]() Symmetric encryption: Symmetric encryption is a type of encryption where the same key is used to both encrypt and decrypt data. These include disk encryption, symmetric encryption, and end-to-end encryption, wherein the cloud provider never has access to user data. Cloud storage encryption overview In this section, we’ll cover the most common encryption schemes used on cloud data storage services. Furthermore, unlike some portable USB drives or hard drives, access to sensitive data can easily be revoked or via cloud permissions, yielding significant safety benefits. The cloud storageservice provider subsequently manages the security of the data, and the user or organization will not have to worry about losing the data if a single device is lost or stolen. This allows users to access the data from any device that has an internet connection, or to sync data locally with a desktop folder (in fact, this was one of Dropbox’s biggest innovations that sparked initial massive growth). The service provider makes the data available to the user over web, iOS, Android, and other consumer applications. Consumer cloud storage providers include Dropbox, Box, and Google other companies operate cloud storage services for enterprises and applications, such as Amazon Web Services (AWS). Now, user data is stored on servers that are owned and operated by a service provider, which subsequently owns, operates, or rents storage in data centers. Users can manage permissions, choose providers with different encryption practices, and ensure compliance with data processing regimes, such as GDPR and CCPA. In contrast, cloud storage allows users to upload, store, and share data online, from gigabytes of research and documentation to personal photos and videos. Files were either sent over email, or shared in physical form using USB drives, portable hard drives, or other cumbersome hardware. Why cloud storage? Before cloud storage, sharing files and information was slow, frustrating, and significantly less secure. We’ll also cover some of the most popular cloud storage providers and analyze their security practices, encryption schemes, and privacy policies. ![]() This article outlines some best practices to employ when you’re using cloud storage services, including security practices, data protection guidelines, and suggestions for the privacy and encryption practices to keep your data safe. However, choosing the proper cloud storage platform and setting it up properly are prerequisites to ensuring good security and privacy practices for your data. Cloud storage is a convenient, safe way to manage and share important documents and files. ![]()
