This lesson focuses on Network Security, Secure Configuration, Patching, and Review within Oracle Database 19c: Security Fundamentals.
The activity is tied to a legacy database reviewed for broad accounts, PUBLIC grants, audit gaps, and network exposure, so the configuration, development, process, or support decisions are specific to this Oracle course.
Demonstrate listener and service exposure 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.
Implement a controlled workshop covering SQL*Net encryption, firewalls, allowlists, and TLS awareness and configuration baselines, parameters, patches, and vulnerabilities, then test a failure or exception involving monitoring, incidents, evidence, and access review.
The Network Security, Secure Configuration, Patching, and Review result must be reproducible, traceable to approved inputs, and consistent with the expected Oracle product behavior.
Diagnose issues in listener and service exposure, SQL*Net encryption, firewalls, allowlists, and TLS awareness, configuration baselines, parameters, patches, and vulnerabilities, or monitoring, incidents, evidence, and access review without making an unverified production change.
Learners isolate the smallest proven cause, apply a reversible correction, rerun validation, and record the preventive action.
