What you'll learn

  • protecting a database from unauthorized access, misuse, or threats that can compromise the confidentiality, integrity, and availability (CIA) of the data
  • Database privacy ensures that sensitive information is not exposed to unauthorized users or misused, and that individuals’ personal data is handled in complianc
  • Use strong authentication mechanisms
  • Students learn the highly technical aspects of how Security is structured and designed to build effective, efficient, and reliable applications

Course content

1 section • 5 lectures • 1h 34m total length

  • Introduction19:53

    Explore the fundamentals of database security and privacy, including security architecture and the four-module database management system (users, query processor, storage manager, disk storage) with confidentiality, availability, and integrity.

  • Security Fundamentals24:56

    Master security fundamentals, including vulnerability, asset types, access control, and authentication, while applying encryption, password policies, Kerberos, and secure file transfer in database environments.

  • Administration Policies25:46

    Explore database administration policies by learning to create, modify, and remove SQL Server logins, manage passwords, and use database links and remote servers to secure access.

  • Implementing Password Policies16:44

    Implement password policies and login management for database security, including creating and altering logins, granting privileges, and enforcing encryption. Explore Kerberos and NTLM authentication mechanisms to secure access.

  • Overview6:44

    Review security architecture, asset types, authentication, and password policies, then learn to create and modify users, grant privileges, manage database links, and understand Kerberos and encryption.

Requirements

  • No programming experience is needed

Description

This course provides an in-depth exploration of security and privacy issues related to database systems. Students will learn the fundamental principles and practices used to protect sensitive data stored in databases from unauthorized access, misuse, and breaches. Topics include access control models, authentication and authorization mechanisms, encryption techniques, database activity monitoring, vulnerability management, and the mitigation of common attacks such as SQL injection.Additionally, the course covers data privacy regulations and techniques such as data anonymization, pseudonymization, and compliance with laws like GDPR and HIPAA. Students will gain hands-on experience through practical labs and projects that simulate real-world database security scenarios. By the end of the course, participants will be equipped with the skills to design, implement, and maintain secure and privacy-aware database systems.

Key Topics:

  • Database security models (DAC, MAC, RBAC)

  • Authentication and authorization

  • SQL injection and mitigation

  • Data encryption (at rest and in transit)

  • Backup, recovery, and auditing

  • Database activity monitoring (DAM)

  • Insider threat detection

  • Data privacy laws and compliance

  • Anonymization and data masking techniques

  • Secure database design best practices

    Prerequisites:

    • Basic knowledge of databases (e.g., SQL)

    • Familiarity with computer networks and operating systems is recommended

    • Key Components of Database Security:

      1. Authentication & Authorization

        • Ensure only authorized users have access to the database.

        • Role-based access control (RBAC) is common.

      2. Encryption

        • Data-at-rest: Encrypt stored data to protect it if the physical storage is compromised.

        • Data-in-transit: Use TLS/SSL to secure data transmission between clients and the server.

      3. Auditing and Monitoring

        • Track access and changes to the database.

        • Detect suspicious activities in real-time.

      4. Backup and Recovery

        • Regularly back up data to protect against loss due to system failure or attacks.

        • Have a tested disaster recovery plan.

      5. Database Firewalls

        • Block known attack patterns (e.g., SQL injection) before they reach the DBMS.

      6. Patching and Updates

        • Regularly update DBMS software to fix security vulnerabilities.
