An Introductory Guide To Cloud Encryption

IT Biz Today Staff

Cloud storage vendors provide encryption solutions to turn data into code and then store it in the cloud. This is done to stop the data’s unauthorized access. Applications of cloud encryption include secured connections, encryption of sensitive data like usernames and passwords, and end-to-end encryption (E2EE) of data transferred to cloud storage. In the encryption models mentioned above, vendors encrypt the data they get transferring keys to customers to enable safe decryption on an as-need basis.

Encryption is considered a very effective way of securing data and it involves scrambling the things contained in any database, computer, or file so that one can only decrypt it with a key. Organizations will be able to confirm that just their people have the right to use confidential data by implementing encryption and through encryption key management. If the encrypted data is stolen, lost, or unauthorizedly accessed, it cannot be read and is worthless without the key.

Challenges In Cloud Encryption

Encryption may be shown to be effective in strengthening data security, but it is underused. This is among the main challenges related to encryption. The application side of it is becoming more common, with more businesses wanting cloud vendors to offer greater measures of security to make better compliance and maintain efficiency.

Extra bandwidth is needed to convert data into code and then transfer it to cloud storage. This is a factor that brings about a change in the cost for vendors and customers. Therefore, several vendors offer limited encryption services, whereas some clients just encrypt the data onsite before having it stored in the cloud. Those people do it because the strategy potentially reduces their expenses, and it possibly keeps every encryption key and the whole process in their setting.

Cloud Encryption Advantages

Only authorized people can read encrypted data using its decryption keys, and this is the main advantage of cloud data encryption. It confirms that even though an unauthorized person accesses it, the data cannot be used provided that the keys stay secure. This will be particularly useful when uploading data to cloud storage because it will safeguard the content in the case of the cloud account, computer, or vendor being compromised.

Industries that have to follow regulatory requirements should also rely on cloud encryption. A combination of cloud encryption and other data security measures allows organizations to conform to the strict requirements of the Health Insurance Portability and Accountability Act, Payment Card Industry Data Security Standard, and the Sarbanes–Oxley Act.

An organization in the healthcare, e-commerce, retail, or financial sector that has embraced the cloud has to be ready to fulfill the data security challenges related to utilizing cloud solutions. Cloud encryption enables organizations to proactively defend against data violations and attempts to illegally access a system or network, plus it is indispensable in a world driven by data.

Best Practices For Cloud Data Encryption

When selecting a vendor, consider your security requirements for data to be transferred to cloud storage. Discover which data you want to convert into a coded form, and then choose a vendor that offers enough encryption for your requirements. For instance, marketers who utilize cloud service to store videos and graphics might need encryption just for the account credentials. Conversely, producers and engineers who utilize it to share both design documentation and source code will possibly need the help of cloud vendors that offer E2EE. At least, select vendors who utilize HTTPS to make every connection encrypted.

Try to encrypt sensitive data in your company before uploading it to cloud storage. It will keep the uploaded data secured even if the cloud computer or your account is damaged. Encryption key management will also be vital and this applies to the keys of your own organization and the ones your provider offers. It is important to store encryption keys in a place different from the data to make sure that the latter is secure. You must also keep important data backups off-site, and audit these often.

One more best practice is to occasionally refresh encryption keys, particularly when these are on the verge of expiring automatically. Some organizations encrypt keys on their own, but this could just occasionally make the process complicated. Implementing multifactor authentication (MFA) for the master encryption key and the recovery key is also a great practice.

There are challenges related to cloud encryption, but the data security needs and regulations of your business cause encryption to be a necessary requirement. Experts regard encryption as an important tool for data security. At the same time, cloud vendors provide various encryption applications to suit an array of security requirements and budgets. Make the effort to know your business’s cloud data security requirements, look into the encryption solutions of different cloud providers, and prepare for safe cloud adoption. Doing these things will allow the organization to benefit from cloud computing and storage without subjecting its data to unwanted risks.
