Database Security and Authorization
This chapter addresses the critical aspects of database security, emphasizing the importance of protecting sensitive data against various types of threats including unauthorized access and data breaches. It covers access control mechanisms such as Discretionary Access Control (DAC), Role-Based Access Control (RBAC), and Mandatory Access Control (MAC), alongside the dangers of SQL injection attacks and the preventive measures needed. Additionally, the roles of data encryption and database auditing in securing and monitoring databases are explored.

What we have learnt
- Database security involves protecting the confidentiality, integrity, and availability of data.
- Common access control methods include DAC, RBAC, and MAC, each with their unique advantages and disadvantages.
- SQL injection attacks exploit application vulnerabilities, and the principal defense is to use parameterized queries.
- Data encryption serves as a vital defense mechanism for data at rest and in transit.
Key Concepts
- -- Database Security
- The collective measures and controls aimed at protecting a database system from unauthorized access and vulnerabilities.
- -- Access Control
- The process by which a Database Management System (DBMS) regulates who can perform what operations on which data and objects.
- -- SQL Injection
- A code injection attack that targets data-driven applications by inserting malicious SQL code into input fields.
- -- Data Encryption
- The transformation of data into a coded format to prevent unauthorized access, using encryption algorithms and keys.
- -- Database Auditing
- The systematic process of collecting and reviewing information about activities performed in a database system to ensure accountability and compliance.
