• Use Cases

1. Bastion Service Overview

Oracle Cloud Infrastructure (OCI) Bastion Service provides a secure way to manage and access resources in private networks. It acts as a secure entry point, allowing authorized users to connect to private instances without exposing them to the public internet. Bastion Service enhances security by reducing the attack surface and ensuring that only authenticated and authorized users can access private resources.

Example: Think of Bastion Service as a secure lobby in a high-security building. Just as the lobby controls access to different parts of the building, Bastion Service controls access to private resources in your cloud environment.

2. Session Management

Session Management in Bastion Service involves creating, monitoring, and terminating sessions. Users can create sessions to connect to private instances using SSH or RDP protocols. Bastion Service provides detailed logs and monitoring capabilities to track session activities and ensure compliance with security policies.

Example: Consider session management as managing a guest list for a private event. Just as you control who enters and exits the event, Bastion Service controls who can create and terminate sessions to access private resources.

3. Security Features

Bastion Service includes several security features to protect private resources. These features include IP whitelisting, session duration limits, and multi-factor authentication (MFA). IP whitelisting restricts access to specific IP addresses, session duration limits ensure that sessions are short-lived, and MFA adds an extra layer of security by requiring additional verification.

Example: Think of security features as layers of security in a high-security vault. Just as multiple locks and security measures protect valuable items, Bastion Service's security features protect private resources from unauthorized access.

4. Integration with OCI Services

Bastion Service seamlessly integrates with other OCI services such as Compute, Networking, and Identity and Access Management (IAM). This integration allows you to manage and access private instances within your cloud environment securely. Bastion Service also supports integration with external identity providers, providing flexibility and interoperability.

Example: Consider integration as a well-coordinated orchestra. Each instrument (OCI service) plays its part, and when they work together, they create a harmonious and powerful performance (comprehensive cloud solution).

5. Use Cases

Bastion Service is ideal for scenarios where secure access to private resources is required. Common use cases include managing private instances, troubleshooting network issues, and performing maintenance tasks. Bastion Service ensures that these tasks can be performed securely without exposing private resources to the public internet.

Example: Think of use cases as different rooms in a secure building. Each room (use case) has specific tasks (managing instances, troubleshooting), and Bastion Service ensures that these tasks are performed securely and efficiently.
