Is your business utilizing a public cloud infrastructure and striving to secure data from cloud service providers and other shared teams? If so, Bring Your Own Key (BYOK) is for you. Designed as a security model to allow organizations to gain control over data security.

What is Bring Your Own Key (BYOK)?

BYOK is an enhanced encryption practice where organizations have the ability to encrypt and decrypt data as per their needs and requirements. In simple terms, think of BYOK as a rental space where you have access to everything except ownership of the key.

Unlike traditional models where cloud service providers generate and store encryption keys, the BYOK gives organizations the ability to create, generate and manage encryption keys that are used to secure and protect their data. While organizations need to transfer the encryption key to the respective cloud service providers, it makes no difference as the organization holds the responsibility for key management operations like monitoring BYOK key rotation frequency, managing key distribution phases, and streamlining key revocation procedures.

With the BYOK solution, organizations can protect their sensitive data and applications by segmenting them even in third-party infrastructure, as they have complete control over encryption keys. While its uses, cases and benefits are many, let us first explore a little history and evolution of BYOK encryption.

History and Evolution of Bring Your Own Key

The practice of encryption dates back to ancient times, when the need to protect and safeguard sensitive information arose. It started as a practice,
  • In Egyptian civilization, encoding educational, religious, and taboo practices was documented in secretive ways, requiring specific deciphering skills to interpret them.
  • Later, the Greeks utilized this approach to hide military communications through a device known as the scytale, which involved wrapping a strip of parchment around a staff to reveal a message only readable on a matching staff, introducing the concept of a shared secret key.
  • World War II changed the course of encryption, as it was the beginning of  machine encryption. It was during this time that computers came into existence. The encryption created using those computers would require trying nearly 17,000 combinations.
  • The rise of World Wide Web gave birth to today’s modern cryptography, the RSA algorithm in 1970, which had two encryption keys, one private and one public, underpinning the security of digital communications. Thus, this marks a significant evolution for today’s advanced encryption models, like BYOK.

Established as a security practice where organizations create, manage and maintain their own encryption keys for data in public cloud applications. This approach provides comprehensive control over the encryption keys for the organizations, leading to end-to-end visibility of applications and other activities. As the adoption of public cloud infrastructure seems to be cost-effective, too many organizations heading to a common infrastructure are subject to some serious threats in terms of unauthorized access, compliance risks, data privacy and data integrity.

BYOK vs. Traditional Encryption

When compared to traditional key management, BYOK allows organizations to take full control of their security posture in a shared environment, reducing the fear of data loss and breaches. Let’s analyze BYOK vs. traditional encryption for a detailed understanding of why BYOK security is the most preferred approach among organizations.

Ownership and control

Traditional key management: In this practice, the service provider generates, manages and stores the key responsible for the encryption and decryption of data. The service provider handles all aspects of key management, right from creation to revocation to storage within their infrastructure, known as Key Management Service (KMS).

BYOK: Customers generate their own key encryption through methods like Hardware Security Modules (HSM) or Key Management Service (KMS). This way, customers can take full advantage of key management functions like creation and maintenance, protecting their data and applications in a way they need and require.

Security Responsibility

Traditional Key Management: As the service provider owns the full rights to the key encryption, they will ensure robust security measures like access controls, encryption and physical security like implementing surveillance are incorporated as per every shared application’s needs and requirements.

BYOK: On the other hand, customers having full control over the key encryption can tailor security protocols, custom policies and procedures that align with current threats and breaches, which can later be modified or customized according to various threats and vulnerabilities.

Data privacy and compliance

Traditional Key Management: Ensuring updated compliance and data regulation rules is important to secure and protect the data. Also, as customers have limited to no control over the provider’s key management, it is important to be on track with the latest security regulations, compliance certifications and audits.

BYOK: By overviewing key encryptions and other safety protocols, BYOK key management empowers organizations to keep track of compliance risks, regulatory adherence and other audits. This way, customers can ensure their data is not just protected but also well aligned with the latest regulatory measures.

Integration and Compatibility

Traditional key management: With key encryption managed within the service provider infrastructure, a seamless and straightforward BYOK integration is enabled.

BYOK: With customers managing key encryption systems, integration with the service provider’s infrastructure can be quite challenging and complex. While creating key encryption, it is recommended to ensure that it will be compatible with  the service provider’s infrastructure.

Risk Management

Traditional key management: Managing unauthorized access and other security risks solely depends on the service provider for they are the owners of key encryption systems.

BYOK: Whereas in BYOK, customers have unlimited control over data integrity and security. Also, they can implement security policies according to their own convenience, leading to enhanced and streamlined risk mitigation measures.
