Study Notes
Database Security
- Database security consists of mechanisms designed to protect databases from both intentional and accidental threats.
- A subject is an entity (user, program) granted permission to access a database object in a specific mode.
- Objects refer to entities (such as tables or views) upon which actions can be executed.
Access Control
- Access modes define controllable actions that subjects can perform on objects, determining the level of interaction allowed.
- Access control is a systematic process that can be efficiently implemented using tables and automated computer systems.
Authorization and Identity
- Authorization involves validating a subject's claimed identity, confirming that individuals are who they assert to be.
Data Access Controls
- Virtual Private Database (VPD) enables data access controls at granular levels, such as rows or columns within a database.
- Label Security employs row-level data classifications to enforce specific access rules, ensuring users only see data they are permitted to access.
Database Links and Data Management
- A database link serves as a pointer connecting one database to another, facilitating data access and interactions.
- Data is a critical resource that requires meticulous management and control comparable to other corporate assets.
Database Administration
- Protecting the database remains a fundamental and essential responsibility of a Database Administrator (DBA), emphasizing its criticality in data management.
- Network connections are acknowledged as database objects, reinforcing their role in data interactions.
Security Practices
- The principle of limited privilege restricts user and process capabilities, minimizing the risk of catastrophic damage to the database.
