Database Security covers access control, data integrity, and secure design for relational and object-relational databases.
What DBST 668 covers
Prerequisite: DBST 651. An overview of both the theory of and applications for providing effective security in database management systems. Topics include conceptual frameworks for discretionary and mandatory access control, data integrity, availability and performance, secure database design, data aggregation, data inference, secure concurrency control, and secure transactions processing.
Models for multilevel secure databases for both relational and object-relational databases are analyzed. Assignments focus on database security concepts and require use of a remote access laboratory.
Typical DBST 668 assignments
Expect a remote-lab assignment requiring you to apply a specific access control model (discretionary or mandatory) to secure a database design.
Key topics in DBST 668
- Discretionary and mandatory access control
- Data integrity and availability
- Secure database design
- Multilevel secure database models
Writing tips for DBST 668
Follow the assignment instructions and rubric line by line
UMGC graduate assignments for DBST 668 are graded against a specific rubric or grading criteria your instructor provides — every requirement has to be visibly addressed. Skipping a requirement because it seems minor is one of the most common reasons a strong submission loses points.
Document your remote-lab database work, not just the final schema or query
DBST 668 assignments require use of a remote access laboratory, and are usually graded on the actual database design or query process — the modeling decisions, the tradeoffs considered, the steps taken — not just a final schema diagram or query result shown without explanation.
Use current, credible database technology sources
Database technologies (NoSQL, distributed systems, security standards) evolve quickly. Strong DBST 668 submissions cite current vendor documentation and recent peer-reviewed database research rather than relying on outdated general-IT sources.

Why students seek help with DBST 668
Students sometimes describe database security concepts generally without applying a specific named access control model — the rubric typically wants that specific model applied to a concrete database design.
