Storage encryption is a key element in keeping enterprise data safe.
Most enterprises use a combination of encryption methods to protect their data on premises, in motion and in the cloud, so it's important to understand the different types and best practices for implementation.
Storage encryption is the use of encryption methods for data both in transit and on media such as hard drives.
Secure encryption uses so many cryptographic keys that no human can guess it, nor can a computer easily calculate the correct string of characters by trying every potential combination.
Storage encryption involves various tools, technologies and approaches for data at rest and in motion.
The encryption key is a public key shared among everyone who needs to send encrypted data.
Asymmetric encryption is more expensive to produce and takes more computing power to use, as the encryption key is often between 1,024 and 2,048 bits.
It's more secure than symmetric encryption but isn't suited for large data packets.
Enterprises use numerous symmetric encryption methods, including Advanced Encryption Standard and Twofish.
Twofish is used in both hardware and software and is considered the fastest symmetric encryption method.
ECC is an advanced asymmetric encryption method that provides security of massive encryption keys with a smaller and more efficient footprint.
ECC often secures digital signatures and shared symmetric encryption keys.
Enterprises should have a comprehensive data storage encryption strategy.
Which encryption method to choose depends on the data, its location, its use and any regulatory requirements.
Decide first on symmetric or asymmetric encryption and then the encryption option.
Many cloud storage providers include data encryption, so refer to their documentation for the details.
Healthcare enterprises must check that the encryption complies with HIPAA, while financial services companies may require Payment Card Industry Data Security Standard compliance.
The principle of least privilege should apply to the entire IT infrastructure, including data encryption.
Grant relevant access to encryption methods based on where the data is, where it moves to and from, who uses it and what regulatory requirements apply.
In an enterprise, data encryption must be scalable so it can handle user bases and IT devices or systems that may expand.
