Which of the following is true about Oracle Cloud’s security features?

The assertion that every service automatically includes basic security is true regarding Oracle Cloud's security features. Oracle Cloud Infrastructure is designed to integrate foundational security measures into its services, ensuring that baseline protections are in place. This approach enhances the overall security posture of the cloud environment, providing features such as data encryption, firewall capabilities, identity and access management, and compliance with industry-standard security protocols by default.

This automatic inclusion of basic security safeguards the user's data and operations while utilizing the platform, making it easier for organizations to maintain compliance and protect sensitive information without needing to establish these fundamental measures from scratch.

In contrast to this, the other statements suggest misunderstandings about cloud security. Security being optional undermines the essential nature of safeguarding data, while the notion that users must implement all security measures manually overlooks the built-in defenses that cloud providers like Oracle incorporate. The claim that security is only available in premium services is also misleading, as foundational security features are typically included in standard service offerings.
