Improve Security and Trust With Cloud-based Key Control

How safe are your cloud-stored keys? Where and how secret keys are kept can have a substantial impact on the overall security of the data.

Key security in the cloud

Here are several things to keep in mind and think about when it comes to key data security in cloud computing:

Protection Level

Secret keys are the arithmetic numerical string sequences that enable cryptographic operations. They must be protected to the same degree of control, if not greater, as the data they protect. According to the organization’s data security policy, this level of protection is determined by the sensitivity of the data. We must remember that the cryptosystem’s power is only valid if keys are not leaked (except for public keys).

A hardware security module (HSM) is a tool used in servers, data transfer, and log files that can securely store and process encryption keys. If correctly implemented, it is significantly more powerful than storing and maintaining keys in software.

Key Retrieval

Accessing a specific user’s key should be difficult for anybody other than that user. Yet, there are times when an organization has to acquire a user’s key without the user’s involvement. This might be because the person was dismissed, or misplaced their key. To access the data, you must have the technology and method in place. Typically, this involves a technique that covers multiple people, each possessing only a piece of the key.

Distribution of Keys

Key generation for a cryptosystem may be complicated and risky. You need a key management system which needs a secure channel to begin the key creation process. Passing keys out of the band is a time-consuming and costly practice. Furthermore, keys should never be transmitted in cleartext.

Annulment of a Key

When a user should not have access to critical content anymore, or when a key is accidentally or illegally exposed, you need a mechanism for suspending the key or that user’s capability to use it.

Key Vaults

In many circumstances, it is widely preferred to have duplicates of keys kept by a trustworthy entity in a safe environment.

Key Management Services

Keys should never be kept alongside the data they are safeguarding. We should not provide physical access to keys to people who do not have permission.

In cloud computing, it is preferable to store the keys somewhere other than the cloud provider’s data center. One option is for you to keep the keys, but this needs a costly and complicated set of infrastructure as well as a competent staff.

Conclusion

Now you know how to manage your keys on the cloud. This is a practice that, if implemented successfully, increases security and trust in the cloud.
