It ensures that sensitive data cannot be understood or accessed by unauthorized users even if they manage to gain access to the database. Encrypted data can only be decrypted with a specific key, which is known only to authorized users.
In databases, encryption is typically used at two levels – data in transit (when it is being transferred between systems) and data at rest (when it is stored on a disk or server). This makes it difficult for hackers or malicious insiders to steal or manipulate sensitive information.
2. Access Control: Access control refers to the process of controlling who has access to what information within a database. Each user has a unique username and password, and their level of access is determined by their role within the organization (e.g., administrator, manager, regular user). This helps prevent unauthorized users from accessing sensitive information.
Access control can also restrict certain actions that can be performed on the data, such as viewing, creating, modifying, or deleting records. This protects against accidental or intentional modifications to important data.
Combining encryption and access control helps ensure that only authorized personnel have access to sensitive information in a database, making it more difficult for malicious actors to steal or tamper with the data. Together they form a layered defense mechanism that provides an additional level of security for databases.
