Oracle Database 19c: Security Fundamentals — Lesson 1: Security Architecture, Accounts, Authentication, Profiles, and Admin Access

Technical Scope

• security objectives and threat surfaces
• users, authentication, common and local accounts
• profiles, password policy, and resource controls
• SYSDBA, OS access, and administrative separation

Instructor Demonstration

Demonstrate security objectives and threat surfaces inside a legacy database reviewed for broad accounts, PUBLIC grants, audit gaps, and network exposure, then capture the exact configuration, command, transaction, report, or code evidence that proves the result.

Applied Workshop

Implement a controlled workshop covering users, authentication, common and local accounts and profiles, password policy, and resource controls, then test a failure or exception involving SYSDBA, OS access, and administrative separation.

1. Confirm environment, identity, data, dependencies, and expected result.
2. Complete the product-specific implementation or analysis.
3. Capture commands, configuration, output, logs, transactions, or reports.
4. Explain the operational, security, performance, or business trade-off.

Validation Standard

The Security Architecture, Accounts, Authentication, Profiles, and Admin Access result must be reproducible, traceable to approved inputs, and consistent with the expected Oracle product behavior.

• The intended target and ownership are verified.
• The result is supported by reproducible evidence.
• Security, performance, reliability, and support impact are reviewed.
• Unexpected behavior is investigated before acceptance.

Failure Analysis

Diagnose issues in security objectives and threat surfaces, users, authentication, common and local accounts, profiles, password policy, and resource controls, or SYSDBA, OS access, and administrative separation without making an unverified production change.

Learners isolate the smallest proven cause, apply a reversible correction, rerun validation, and record the preventive action.
