Oracle Cloud Security

OCI offers several solutions for each pillar that enhance the security and compliance of the cloud platform; these are:

Customer Isolation:  It enables the deployment of your application and data assets in a completely isolated environment from other tenants and Oracle workers.

Data Encryption: It helps you satisfy your security and compliance standards for cryptographic algorithms and key management by protecting your data while at rest and in transit.

Security Controls: It reduces the risk posed by malicious and unintentional user actions by restricting access to your services and separating operational duties.

Visibility: It offers thorough log data and security analytics for auditing and keeping track of resource usage. Due to this visibility, you can meet your audit obligations and lower operational risk.

Secure Hybrid Cloud: It allows you to utilize your security resources, including user accounts and policies. It enables you to access your cloud resources and protect your data and application assets using third-party security solutions.

High Availability: It offers fault-tolerant data centers that support scalable, highly available architectures resistant to network attacks.

Verifiably Secure Infrastructure: It deploys strong security controls and adheres to strict procedures throughout the whole creation and operation of cloud services. OCI complies with Oracle’s stringent security requirements through external audits, certifications, and attestations. To internal security and compliance teams, clients, auditors, and regulators, our secure infrastructure enables you to demonstrate compliance readiness.

Primary Security Considerations: Using any program safely starts with the following guiding principles. Plan, create, deploy, and manage your resources in Oracle Cloud Infrastructure by these guidelines.

• Update your software: Use the most recent product version and any relevant fixes.

• Privileges should be kept to a minimum: Give users only the access they require to complete their tasks. User privileges should be periodically reviewed to determine their applicability to the moment’s needs.

• Watch the system’s activity: Determine who should have access to which system components and how often they should be accessed, and then keep an eye on those components.

• Utilize the security features of the Oracle Cloud Infrastructure: For additional details on security services, Update your knowledge of security. Oracle often publishes security-related alerts and patch updates. Install all security updates as quickly as you can.

• Basic Resource Protection: Consider which resources need to be secured, how much access to allow to those resources, and the effects of security failure on those resources as you prepare your Oracle Cloud Infrastructure deployment.

Which Resources Must be Protected?

• Customer data, such as credit card numbers

• Internal data, such as proprietary source code

• System components (protected from external attacks or intentional system overloads)

Who Are You Protecting Data From?

To decide who requires access to what data, analyze your workflows. For example, keep subscriber data secure from other subscribers while allowing someone in your company access for management purposes.

What Happens if Protections on a Strategic Resource Fail?

An issue with your security plan may occasionally be inconvenient. You can secure it by being aware of each resource’s security implications.

Shared Security Model   

You and Oracle both share responsibility for security in the Oracle Cloud Infrastructure. However, you must be aware of your security and compliance obligations to securely execute your workloads in OCI.

We are in charge of maintaining the security of the cloud infrastructure (including data center facilities, hardware, and software systems) in a shared, multi-tenant computing environment. You are responsible for your workload security and safe cloud resource configuration (including computing, network, storage, and database).

You are more accountable since you own the entire software stack (operating systems and above) on a fully isolated, single-tenant, bare-metal server where you deploy your application. In this environment, you are responsible for the following tasks:

• Keeping your Tasks Secure

• Setting up your services (network, database, storage) securely

• Configuring, deploying, patching, and managing the software components that you use on the bare metal servers in a safe manner

Zero Trust Security

Zero Trust Security has emerged as a critical concept for cybersecurity and IT professionals, fundamentally reshaping how organizations approach network security. This paradigm shift challenges traditional assumptions by assuming minimal trust for users and devices connected to an organization’s network. The underlying principle is to establish and maintain trust through carefully designed security controls.

The evolution of Zero Trust Security has been driven by factors such as the rise of public cloud services and the recognition of threats originating from both external attackers and insiders. Although adopting a Zero Trust approach demands substantial effort, it proves essential for safeguarding modern digital landscapes. Oracle’s Oracle Cloud Infrastructure (OCI) steps in to assist organizations in their Zero Trust initiatives by offering built-in security features that rapidly and effectively secure workloads in the cloud.

Embracing Zero Trust necessitates a commitment to gradual advancement in technical architecture and business processes. OCI, as a next-generation cloud, aligns with this approach. Designed to empower business transformation, OCI furnishes high-performance computing for cloud-native and enterprise IT workloads. By prioritizing a security-first approach, Oracle ensures that security is seamlessly integrated into OCI’s foundation.

Oracle supports organizations in their security journey through three core tenets: simplicity, offering user-friendly security controls; prescriptiveness, imparting expert guidance for a robust security posture; and integration, embedding security across all service levels. This approach delivers comprehensive security across infrastructure, platform, and software services by reducing manual tasks and human errors.

Security Services

• Role-Based Access Control: IAM introduces the concept of Role-Based Access Control (RBAC), enabling you to define and assign roles to users with specific privileges. This fine-grained control empowers administrators to grant access only to the resources and actions essential for each user’s responsibilities.

• Policies and Authorization: IAM policies provide the guidelines for governing access permissions. These policies outline what actions a user can perform on specific resources. By crafting and enforcing well-defined policies, you ensure that access is limited to authorized individuals, mitigating potential security risks.

• Compartments for Segregation: IAM introduces the concept of compartments, allowing you to segregate resources and manage access on a per-compartment basis. This compartmentalization enhances security and streamlines management by providing isolation between projects, departments, or applications.

• Authentication Mechanisms: IAM offers various authentication methods, including user credentials, API keys, and federated identity providers. This flexibility enables secure authentication tailored to your organization’s needs, ensuring only authorized users gain entry.

• Virtual Cloud Networks (VCNs): At the core of OCI’s networking security lies the concept of Virtual Cloud Networks. VCNs enable you to create isolated network segments, controlling traffic flow and segmentation within your cloud environment. This crucial tool ensures that resources remain shielded from unauthorized access.

• Security Lists and Network Security Groups (NSGs): Within VCNs, Security Lists and NSGs act as gatekeepers. Security Lists define traffic flow, allowing or denying communication to and from resources. NSGs take this a step further, enabling more granular control by regulating traffic at the subnet level.

• Key Management: At the heart of data protection lies the management of encryption keys. OCI offers a robust Key Management service that empowers you to generate, store, and control cryptographic keys used to encrypt and decrypt sensitive data. This service assures that even if data is accessed, its contents remain indecipherable without proper authorization.

• Data Encryption: Encrypting data at rest and in transit is a fundamental measure to thwart unauthorized access. OCI’s Data Encryption service offers the means to safeguard data through encryption mechanisms, adding an extra layer of security to sensitive information.

• Database Firewall: The OCI Database Firewall is a critical line of defense against cyber threats. This service thwarts unauthorized attempts to access or manipulate data within databases by monitoring and controlling database traffic.

• Audit and Monitoring: OCI’s Audit service provides a comprehensive trail of all activities within your cloud environment. By enabling auditing, you gain real-time visibility into changes, user actions, and system events, fostering a proactive approach to security monitoring.

• Compliance Standards: In cloud security, adhering to industry-specific and regulatory compliance is necessary. OCI’s Compliance Service helps you meet these standards by providing pre-configured templates and reports tailored to various compliance frameworks.

Conclusion

Oracle Cloud Security is a robust offering designed to help organizations maintain their cloud resources’ confidentiality, integrity, and availability. Organizations should consider their security responsibilities and implement additional security measures to meet their specific security objectives.
