CYOP 350 at the University of Maryland Global Campus focuses on keeping data safe where it lives: inside the database.
UMGC describes it as a study of processes and techniques for securing databases. The objective is to design, build and maintain databases to minimise risks and security attacks.
Topics include privileges and roles, user accounts, encryption, authentication methods and auditing. The course was formerly SDEV 350 (credit for only one), and the prerequisite is CMSC 320 or CYOP 200.
Students often know SQL but have rarely administered security in a database. The course rewards precise thinking about who can do what, and how you would prove it.

What CYOP 350 Covers
| Topic | In plain language |
|---|---|
| Privileges | Specific permissions, such as reading or changing a table |
| Roles | Bundles of privileges assigned to groups of users |
| User accounts | Creating, managing and removing database logins |
| Encryption | Protecting data at rest and in transit |
| Authentication methods | How the database confirms who is connecting |
| Auditing | Recording database activity for review |
Key Concepts Explained
Least Privilege with Roles
Granting privileges to roles, then roles to users, makes access easier to manage and review. Each role should have only what the job needs.
Example: A clinic database has a patients table. A reception role gets SELECT and INSERT on patient contact columns only. A clinician role gets SELECT and UPDATE on clinical columns. The application's own account can run only the stored procedures it needs. No everyday account has DROP or ALTER rights. When a receptionist leaves, removing one role membership ends their access.
Encryption at Rest and in Transit
Encryption at rest, such as transparent data encryption or column-level encryption, protects data if storage or backups are stolen. Encryption in transit, using TLS for connections, protects data travelling between the application and the database. Key management matters as much as the algorithm: keys should be stored separately from the data.
Auditing
Audit trails record logins, privilege changes and access to sensitive data. They support investigations and compliance, but only if logs are protected from tampering and someone reviews them.
Common Database Threats and Controls
| Threat | Key controls |
|---|---|
| SQL injection | Parameterised queries, least privilege |
| Excessive privileges | Roles, regular access reviews |
| Stolen backups | Encrypted backups, separate keys |
| Weak authentication | Strong passwords, integrated or multi-factor login |
| Insider misuse | Auditing, separation of duties |
Use a table like this in assignments to show that each control answers a named threat.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Role and privilege design | Least privilege | Map job functions to minimal permissions |
| Security configuration lab | Implementing controls | Script each step and verify it works |
| Encryption plan | Protecting stored and moving data | Say what is encrypted, how, and where keys live |
| Audit analysis | Monitoring database activity | Define what to log and how to review it |
Designing Roles for a Small Application
Role design questions are common in database security work. Start from the jobs people do, not from the tables.
Example: An online shop database has three groups of users. The web application account may read products and insert orders, but cannot delete anything or read stored payment tokens. Support staff may read orders and update shipping addresses. Only the database administrator role can change schemas, and that account is not used for daily work. Audit logging records every privilege change.
Explain why each permission is needed. Any permission you cannot justify should be removed.
Where Students Get Stuck
- Granting to users directly. Use roles so access stays manageable.
- Over-privileged application accounts. Apps rarely need administrator rights.
- Encryption without key management. Explain where keys are stored and who can use them.
- Logging everything, reviewing nothing. Say how audit logs will be used.
Study Tips for CYOP 350
- Practise GRANT, REVOKE and role commands in the database system your course uses.
- Draw an access matrix of roles against tables before writing scripts.
- Test every role by logging in as it and trying actions it should not perform.
- Keep notes on the differences between database products you meet.
