This advanced course develops the knowledge and skills needed to protect enterprise databases against unauthorized access, data exposure, privilege abuse, and operational threats. It covers security architecture, database hardening, identity and access management, encryption, secure application connectivity, monitoring, incident response, and recovery.

The course takes a vendor-neutral approach to relational databases, with additional coverage of NoSQL and cloud-managed database environments. Platform-specific features and configuration requirements vary by database product, version, and deployment model.

 

Duration 5 Days – 35 hrs.

 

Objectives

• Analyze database threats, attack surfaces, and security requirements.
• Design layered security controls for enterprise database environments.
• Apply database hardening and vulnerability remediation practices.
• Implement least-privilege access and separation of duties.
• Select encryption, key management, and sensitive-data protection controls.
• Secure application connections and reduce injection risks.
• Configure database auditing, monitoring, and actionable alerts.
• Address security risks in cloud-managed, replicated, and NoSQL databases.
• Develop database incident response and secure recovery procedures.
• Produce an integrated database security design and implementation roadmap.
