Encryption in DBMS
Encryption in databases is a critical aspect of database security, aimed at protecting sensitive data from unauthorized access or disclosure. Encryption involves transforming data into a secure, unreadable format using cryptographic algorithms. Here are the key aspects of encryption in databases:
- Types of database encryption:
- Data-at-rest encryption:
- Purpose: Encrypts data when stored on disk or other storage media
- Protection: Guards against unauthorized access to the physical storage medium (e.g., hard drives or SSDs)
- Data-in-transit encryption:
- Purpose: Secures data as it is transmitted between the database server and clients
- Protection: Safeguards against interception and eavesdropping during data transmission over networks
- Data-in-use encryption:
- Purpose: Focuses on protecting data while it is being processed or used by applications
- Protection: Guards against unauthorized access during computations or processing stages
- Data-at-rest encryption:
- Encryption algorithms:
- Symmetric...
