Abstract
As more and more businesses move to cloud-based Software-as-a-Service (SaaS) solutions, the security of sensitive data stored in the cloud becomes increasingly important. Encryption at rest is a critical component of cloud security, ensuring that data is protected even when it is stored on disk. This white paper discusses the encryption at rest implementation for solution, including the encryption algorithm, key management, and access control mechanisms.
Introduction
Lexzur provides businesses with a cloud-based platform for managing their data and applications. As part of our commitment to security, we have implemented encryption at rest to protect sensitive data stored on our servers/your servers. Encryption at rest is a form of encryption that encrypts data before it is written to disk, and decrypts it when it is read back from disk. This ensures that data is protected even if the disk is compromised.
Encryption Algorithm
We have chosen the Advanced Encryption Standard (AES) algorithm to encrypt data at rest in our SaaS solution. AES is a symmetric-key encryption algorithm that is widely recognized as one of the most secure encryption algorithms available. AES uses a block cipher with a key size of 256 bits CBC, providing a high level of security for our customers' data.
Access Control
In addition to encryption at rest, access control mechanisms are in place to ensure that only authorized personnel can access customer data. We use role-based access control (RBAC) to manage access to customer data, which allows us to grant access to specific data sets based on an individual's role in the organization. RBAC provides a fine-grained level of access control, ensuring that only authorized individuals can access sensitive data.
Conclusion
Encryption at rest is a critical component of cloud security, particularly for Lexzur where sensitive data is stored in the cloud. Our implementation of encryption at rest for our solution uses the AES encryption algorithm and RBAC access control mechanisms to ensure that only authorized personnel can access customer data. By implementing encryption at rest, we are able to provide our customers with a high level of security for their sensitive data.
