Cloud Key Management Services: Advantages and Disadvantages

Cloud Key Management Services: Advantages and Disadvantages

Key Sections

Cloud Key Management, in the context of cloud computing, involves the secure administration of encryption keys. Encryption keys are pivotal in safeguarding data stored and processed in the cloud, ensuring its confidentiality and integrity. This encompasses key generation, secure storage, periodic rotation, access control, auditing, and integration with cloud services. Cloud Key Management systems also aid compliance with industry-specific data security regulations. Various cloud service providers offer Key Management as a Service (KMS), adding an extra layer of protection for cloud-stored data by managing encryption keys effectively, especially when dealing with sensitive or confidential information.

The Importance of Cloud Key Management Services

  1. Data Security

    Cloud Key Management is the foundation of data security in the cloud. It ensures that your data remains confidential and intact, protecting it from unauthorized access and breaches.

  2. Regulatory Compliance

    Many industries have specific data security and compliance requirements. Cloud KMS helps organizations meet these regulations by managing encryption keys securely and complying with relevant standards.

  3. Access Control

    KMS provides mechanisms for controlling who can access and manage encryption keys. This fine-grained access control helps prevent unauthorized use of keys.

  4. Key Rotation

    Regularly changing encryption keys, known as key rotation, is crucial for data security. KMS automates this process, reducing the risk associated with long-term key compromise.

  5. Auditing and Monitoring

    KMS solutions offer auditing and logging features, allowing you to monitor key usage and quickly detect suspicious activities or unauthorized access attempts.

Advantages and Disadvantages of Cloud Key Management Services

ServicesAdvantagesDisadvantages
Bring Your Own Encryption (BYOE)
  • The Bring Your Own Encryption (BYOE) concept is the desired trust model for organizations that require full control over access to their data regardless of where it is stored or processed.
  • Regulated industries, such as financial services and healthcare, require keys to be segregated from the cloud Data Warehouse compute and storage infrastructure. BYOE enables organizations to comply with this requirement with encryption applied to the most sensitive columns, and dynamic masking or filtering access to other sensitive columns – achieving the optimal balance between data protection, compliance, analytics and usability of the data.
  • Without exposing encryption keys or sensitive data to the cloud, BYOE enhances the security of data within all cloud services such as Database as a Service (DBaaS) environments, as data is always encrypted before being sent to the cloud.
  • There is an increased latency problem as any data element has to go through repeated cycles of encryption and decryption for utilization in cloud environments, thereby inducing latency related issues.
  • As there are limited interfaces available, there is a requirement to build Custom API’s for integration with multiple cloud service providers, which might not be feasible for a small/medium sized organizations.
  • As the organizations adopt a move to cloud approach, this approach puts increasing pressure on the on-premises infrastructure with respect to scaling, performance, etc.
Bring Your Own Key-Cloud HSM
  • No Key exposure outside the HSM.
  • FIPS advanced level (FIPS 140-2 Level 3 and above) complaint hardware-based devices meeting all regulatory requirements.
  • Can perform all core functions of an on-premises HSM: key generation, key storage, key rotation, and APIs to orchestrate encryption in the cloud.
  • Designed for security.
  • Dedicated hardware and software for security functions.
  • Need specialized, in-house resources to manage key and crypto lifecycle activities.
  • HSM-based approaches are more cost intensive due to the use of a dedicated hardware appliance.
  • Performance overheads.
Bring Your Own Key-Cloud KMS
  • No specialized skilled resources are required.
  • Enables existing products that need keys to use cryptography.
  • Provides a centralized point to manage keys across heterogeneous products.
  • Native integration with other services such as system administration, databases, storage and application development tools offered by the cloud provider.
  • Key exposure outside HSM.
  • FIPS 140-2 Level 3 and above devices not available.
Software
Key
Manage-ment
  • With this approach, service accounts, generic administrative accounts which may be assumed by one or more users, can access these secrets, but no one else.
  • Not compliant with regulatory requirements which specify FIPS-certified hardware.
Secret Management
  • Run the organizations own key management application in the cloud.
  • Lower cost than HSMs and full control of key services, rather than delegating them to your cloud provider.
  • Can perform all core functions of an HSM: key generation, key storage, key rotation, and APIs to orchestrate encryption in the cloud.
  • N/A

Conclusion

With the ever-increasing amount of sensitive data being stored in the cloud, the importance of Cloud Key Management Services cannot be overstated.
