Storage encryption is a basic practice that helps in ensuring the security of data. However, using storage encryption is much more than just its enablement where you want it. Here is a look at three great policies to facilitate an ideal storage encryption at rest.
1. Standardizing Storage Encryption Methods
Even though it is good to use a single type of encryption algorithm for all data , there may be logistical issues that occur that make this impossible. Using a kind of storage encryption at rest can help to simplify both key management and storage management. Furthermore, it is essential to conduct storage performance evaluations both prior to and after the encryption process. All encryption algorithms can carry a limited amount of overhead. During the initial encryption process and normal, day-to-day read operations, this overhead comes into play.
To read the data, it must be decrypted. Decryption applies to everything from accessing files to protecting applications and data. Here, it is important to choose storage encryption algorithms that provide a balance of security with performance.
Data encryption can also help in protecting every bit of information, regardless of its specific nature and security status. Encryption can prevent situations where enterprises have accidentally left data, sensitive or otherwise, unencrypted.
2. Access Control Reviews
Companies should review the access control permissions regularly to safeguard from potential data breaches. Even though this policy might not have much to do with storage encryption, it is very much an important factor. With casual access control, the security benefits gained with storage encryption can prove worthless, in case of unauthorized user attack. If access policies grant universal access to the data, then it becomes easy for attackers to target enterprises
3. Safeguard Encryption Keys
Protecting encryption keys will safeguard users against attacks and potential data loss. Attackers who have gained access to encryption keys can also read the encrypted data. Additionally, if the same keys are lost or destroyed, enterprises lose their ability to access their own data. This kind of loss happens as the organization cannot decrypt it further and leaves the data in a permanently encrypted stage.
