1. Introduction to OCI Autonomous Database Security

• Overview of OCI Autonomous Database’s security features.
• Importance of data security in cloud environments.

2. Provisioning an Autonomous Database

Step-by-Step Provisioning

• Login to OCI Console.
• Navigate to “Autonomous Database”.
• Click “Create Autonomous Database” and fill in the required details.
• Set up network access.

3. Configuring Network Security

Setting Up Virtual Cloud Network (VCN)

• Create a VCN and subnets.
• Set up security lists and network security groups (NSGs).

4. Implementing Data Encryption

Encryption at Rest

• Make sure Transparent Data Encryption (TDE) is enabled by default.
• Managing TDE keys with Oracle Key Vault.

Encryption in Transit

• Set up SSL/TLS for secure data transmission.
• Download and set up client username and password.

5. Setting Up Access Control

Identity and Access Management (IAM)

• Define IAM policies for resource access control.
• Assign roles and permissions.

Database Access Control

• Set up database user accounts and roles.
• Implement fine-grained access control (FGAC).

6. Monitoring and Auditing

Using Oracle Data Safe

• Turn on Oracle Data Safe for comprehensive security management.
• Set up activity auditing and user assessment.

Monitoring Tools

• Use OCI Monitoring for setting alarms and alerts.
• Example command to create an alarm:

oci monitoring alarm create --compartment-id <compartment_OCID> --display-name "HighCPUUsage" --metric-name "CpuUtilization" --threshold 85 --comparison ">" --enabled true
