Encryption as a service – an overview
In these alarming times of cyber-attacks, sensitive data protection, and regulatory requirements, encryption is one of the top priorities. The encryption approach protects data by making it unreadable to anyone who does not have access to the decryption/key information.
There are numerous technologies in use today in IT for data encryption at rest. Every presentation on the topic covers the solution's key management, how it's a huge, complex issue, and how each product solves it better. This is all useful information for businesses, but when these encryption and key management technologies are deployed to the cloud, the situation becomes much more complicated.
Encryption can help protect data in both the active management and storage phases. The objective of encryption is that no one can access data until it is decrypted, but for cloud service providers, this becomes a problem (CSPs). They also require access to the necessary decryption keys because they can't process encrypted user data. On request, users must either forward the keys to the CSP or authorize the CSP to hold them on-premises.
Because users must disclose their decryption keys, this standard model partially defeats the concept of cloud security. When data gets decrypted, it becomes vulnerable, posing a security risk as more businesses shift their data to the cloud. Organizations require a new method that encrypts data at all times. Encryption as a Service (EaaS) can help with this.
What is Encryption as a Service (EaaS)?
Encryption as a service in which Users subscribe to a cloud-based encryption service rather than installing encryption on their own systems. EaaS is an abbreviation for "Encryption as a Service." It also contributes to end-to-end security by ensuring data transit through authorized networks and restricting third-party access.
Encryption as a service assures that data is always encrypted; even if hackers get access to your network, they will only receive indecipherable data. Eaas simply involves Working with a third-party supplier to assist with installing and managing the necessary technologies to ensure that all data is correctly encrypted.
Encryption-as-a-Service (EaaS) prevents cyber thieves or any other unauthorized party from stealing or eavesdropping on your data, such as unencrypted passwords sent over WANs to collect data. Even if the data is at rest and in its early phases and is not yet in transit, you must encrypt it to prevent hackers from exploiting any vulnerabilities. It also contributes to end-to-end security by ensuring data transit through authorized networks and restricting third-party access.
Protecting data demands a "cloud first" approach now that more than 90% of businesses have adopted cloud services and (according to some forecasts) more than half of all IT workloads are handled in the cloud. Three out of every four businesses are concerned about cloud security, and the requirement to take use of cloud capabilities while keeping data safe has security specialists, industry analysts, and even cloud providers attempting to address the same question.
How should data in the cloud be encrypted, and who should have the keys?
In the cloud, there are four basic techniques to encryption key management. Fundamentally, there is a choice to be made between maintaining control over your keys and taking advantage of a fully managed cloud service. Customers who want more control over their data in the cloud will have to put in more effort to manage the added complexity.
CSP Managed Keys - Encryption keys that are managed by the Cloud Service Provider:
The Cloud Service Provider generates, holds and manages the encryption keys. All aspects of the encryption key lifecycle are managed by the CSP and the encryption services are fully embedded into the cloud services of the given CSP.
Customer-Managed Encryption Keys (CMEK):
With CMEK, you use encryption key material developed and delivered by the Cloud Service Provider, but you manage the encryption keys on your own within the Cloud platform.
Customer supplied encryption keys (CSEK) / bring your own key (BYOK):
Customers generate encryption keys with CSEK and provide them to the Cloud platform for encrypting and decrypting their data. Each CSP service must have access to CSEK keys as and when they are required. CSEK gives the customer complete control over key generation, ownership, and management.
Hold your own Key (HYOK):
The customer encrypts data locally before transmitting it to the Cloud platform, which means the customer is responsible for not only the development and management of encryption keys, but also the encryption process itself. The consumer has previously encrypted the data before sending it to the CSP.
EaaS removes the barriers to having a strong encryption programme for cloud service users. It closes security gaps caused by human psychology and makes encryption easier to use without reducing performance. This is excellent news as businesses continue to move to the cloud.
How can CryptoBind help with encryption as a service?
Customers can ensure consistent data protection and transfer apps to any cloud environment using CryptoBind encryption management across on-premises, hybrid, and multiple public cloud environments. CryptoBind KMS is integrated with a wide range of Cloud services. With minimum cost of key management, you can leverage KMS to encrypt data in these services and maintain control over their distributed compute and storage environment.
