In the cloud application. Many software-as-a-service application vendors provide de facto or optional data encryption. Amazon Web Services, Microsoft Azure, Google Cloud, and others provide data-at-rest cloud encryption. On the storage media and/or through the operating system. Most major operating systems and large storage vendors offer data-at-rest cloud encryption software.

Where should cloud encryption software be deployed?Ĭloud encryption software can be deployed at several physical points in a cloud-based architecture, whether it is a private, hybrid, or public cloud. Is the data essential to the operation of the organization?Īny of these scenarios could require both data-in-transit and data-at-rest (disk) encryption.Does the data contain sensitive intellectual property?.Does the data fall under regulatory compliance requirements, such as health records (HIPAA), financial data (PCI, SOX), privacy acts (GDPR), or other legal or contractual obligations?.Users can better determine their cloud encryption solution needs when they examine their operations and data applications. McAfee Endpoint Encryption software provides disk encryption across desktops and laptops with central management and transparent use, while McAfee Complete Data Protection delivers both data-in-transit and storage encryption protection. Several companies can provide strong disk encryption at the user, network, and cloud level. In such cases, users may wish to encrypt data even before connecting to the cloud. While using HTTPS provides a high level of protection to and from the cloud, it may not satisfy more stringent data security requirements. Why use encryption before uploading data to the cloud? The user does not need to take action other than accessing the data with proper authorization and authentication. Software handles all encryption and decryption in the background. Again, encoding and decoding the encrypted data is handled via key exchanges between the user and the device, and keys are only granted to users with the proper authorization and trust certificates. Keys are generated and issued using sophisticated asymmetrical algorithms only exchanged between trusted parties-whose trust certificates are verified during the initial connection.ĭata-at-rest. Data encrypted when it resides on a disk or other storage device ensures that even if an unauthorized user copies or opens the encrypted material, it appears as a useless jumble. Decoding (and encoding) the data within the SSL channel occurs at the user and the destination level using digital keys to lock and unlock the encrypted data. In addition, if a third party intercepts the data stream between the user and the cloud, the unauthorized third party would see only encoded, seemingly meaningless data.

Hence, SSL establishes an important authorized, secure transmission channel. Second, it ensures that only the authorized, intended server can read the data that the user sends or receives. First, it verifies that the cloud user is talking to only the cloud destination it requested.

Also, SSL performs two important security functions beyond encryption. In addition, SSL uses a checksum to help ensure that no data is altered in the transmission.

The SSL wrapper encodes all traffic within the channel so that only authorized users in that communication session can access the contents. This layer is called SSL (secure sockets layer). Based on the internet standard IP protocol HTTP, HTTPS adds a security "wrapper" around the internet communication channel. Fortunately, most data-in-transit is handled natively in web browsers and FTP client software connecting to secure web sites.ĭata-in-transit. The most prevalent form of cloud data-in-transit encryption is the widely used HTTPS protocol. There are two forms of encryption used in the cloud-data-in-transit and data-at-rest.
