Database Security

INTRODUCTION

Database security is a crucial aspect of information security, focusing on protecting databases from unauthorized access, misuse, and threats. It encompasses a range of practices and technologies designed to safeguard data stored in databases from various risks such as cyberattacks, data breaches, and accidental loss or corruption.

HOW IT WORKS:

Database security protects data from unauthorized access, breaches, and loss through several key mechanisms:

1. Authentication: Verifies user identity using credentials and multi-factor authentication.

2. Authorization: Controls user access and permissions based on roles and access control lists (ACLs).

3. Encryption: Secures data at rest and in transit using encryption algorithms and key management.

4. Data Integrity: Ensures data accuracy and consistency with checksums, validation rules, and integrity constraints.

5. Backup and Recovery: Regularly backs up data and defines procedures for restoring data in case of corruption or loss.

6. Auditing and Monitoring: Tracks database activity through logs and real-time monitoring to detect and respond to anomalies.

7. Patch Management: Applies updates and patches to address vulnerabilities in the database software.

These practices collectively safeguard the confidentiality, integrity, and availability of data.

 

KEY FEATURES:

1. Access Control: Manages who can access the database through authentication (e.g., passwords, MFA) and role-based permissions.

2. Authorization: Defines what authenticated users can do with data using granular permissions and access control lists (ACLs).

3. Encryption: Secures data at rest and in transit with encryption algorithms like AES and protocols like TLS.

4. Data Integrity: Ensures data accuracy and consistency through checksums, hash functions, and integrity constraints.

5. Backup and Recovery: Regularly backs up data and allows restoration to specific points in time to protect against data loss.

6. Auditing and Monitoring: Tracks and reviews database activities through audit logs and real-time monitoring to detect anomalies.

7. Patch Management: Regularly updates and patches the database software to fix vulnerabilities.
