Security Overview

Oracle’s mission is to build cloud infrastructure and platform services for your business to have effective and manageable security to run your mission-critical workloads and store your data with confidence.

Oracle Cloud Infrastructure’s security approach is based on seven core pillars. Each pillar has multiple solutions designed to maximize the security and compliance of the platform.

Allow customers to deploy their application and data assets in an environment that commits full isolation from other tenants and Oracle’s staff.
Protect customer data at-rest and in-transit in a way that allows customers to meet their security and compliance requirements for cryptographic algorithms and key management.
Offer customers effective and easy-to-use security management solutions that allow them to constrain access to their services and segregate operational responsibilities to reduce risk associated with malicious and accidental user actions.
Offer customers comprehensive log data and security analytics that they can use to audit and monitor actions on their resources, allowing them to meet their audit requirements and reduce security and operational risk.
Enable customers to use their existing security assets, such as user accounts and policies, as well as third-party security solutions when accessing their cloud resources and securing their data and application assets in the cloud.
Offer fault-independent data centers that enable high availability scale-out architectures and are resilient against network attacks, ensuring constant uptime in the face of disaster and security attack.
Follow rigorous processes and use effective security controls in all phases of cloud service development and operation. Demonstrate adherence to Oracle’s strict security standards through third-party audits, certifications, and attestations. Help customers demonstrate compliance readiness to internal security and compliance teams, their customers, auditors, and regulators.

Also, Oracle employs some of the world’s foremost security experts in information, database, application, infrastructure, and network security. By using Oracle Cloud Infrastructure, our customers directly benefit from Oracle’s deep expertise and continuous investments in security.

Basic Security Considerations

The following principles are fundamental to using any application securely:

  • Keep software up to date. Use the latest product release and any patches that apply to it.
  • Limit privileges as much as possible. Give users only the access necessary to perform their work. Review user privileges periodically to determine relevance to current work requirements.
  • Monitor system activity. Establish who is expected access which system components, and how often, and monitor those components.
  • Learn about and use the Oracle Cloud Infrastructure security features. For more information, see Security Services.
  • Use secure best practices. For more information, see Security Best Practices.
  • Keep up to date on security information. Oracle regularly issues security-related patch updates and security alerts. Install all security patches as soon as possible. See the Critical Patch Updates and Security Alerts website.

Understanding the Oracle Cloud Infrastructure Environment

When planning your Oracle Cloud Infrastructure deployment, consider the following:

Which resources must be protected?

  • Protect customer data, such as credit card numbers.
  • Protect internal data, such as proprietary source code.
  • Protect system components from external attacks or intentional system overloads.

Who are you protecting data from?

For example, you must protect your subscribers’ data from other subscribers, but someone in your organization needs to access that data to manage it. Analyze your workflows to determine who needs access to the data. Consider carefully how much access to give a system administrator; A system administrator might be able to manage your system components without needing to access the system data.

What happens if protections on a strategic resource fail?

Sometimes, a fault in your security scheme is nothing more than an inconvenience. In other cases, a fault might damage you or your customers. Understanding the security ramifications of each resource helps you protect it properly.

Shared Security Model

Oracle Cloud Infrastructure offers best-in-class security technology and operational processes to secure its enterprise cloud services. However, for you to securely run your workloads in Oracle Cloud Infrastructure, you must be aware of your security and compliance responsibilities. By design, Oracle provides security of cloud infrastructure and operations (cloud operator access controls, infrastructure security patching, and so on), and you are responsible for securely configuring your cloud resources. Security in the cloud is a shared responsibility between you and Oracle.

In a shared, multi-tenant compute environment, Oracle is responsible for the security of the underlying cloud infrastructure (such as data center facilities, and hardware and software systems) and you are responsible for securing your workloads and configuring your services (such as compute, network, storage, and database) securely.

In a fully isolated, single-tenant, bare metal server with no Oracle software on it, your responsibility increases as you bring the entire software stack (operating systems and above) on which you deploy your applications. In this environment, you are responsible for securing your workloads, and configuring your services (compute, network, storage, database) securely, and ensuring that the software components that you run on the bare metal servers are configured, deployed, and managed securely.

More specifically, your responsibilities and Oracle's responsibilities can be divided into the following areas:

  • Identity and Access Management (IAM): As with all Oracle cloud services, protect your cloud access credentials and set up individual user accounts. You are responsible for managing and reviewing access for your own employee accounts and for all activities that occur under your tenancy. Oracle is responsible for providing effective IAM services such as identity management, authentication, authorization, and auditing.
  • Workload Security: You are responsible for protecting and securing the operating system and application layers of your compute instances from attacks and compromises. This protection includes patching applications and operating systems, operating system configuration, and protection against malware and network attacks. Oracle is responsible for providing secure images that are hardened and have the latest patches. Also, Oracle makes it simple for you to bring the same third-party security solutions that you use today.
  • Data Classification and Compliance: You are responsible for correctly classifying and labeling your data and meeting any compliance obligations. Also, you are responsible for auditing your solutions to ensure that they meet your compliance obligations.
  • Host Infrastructure Security: You are responsible for securely configuring and managing your compute (virtual hosts, containers), storage (object, local storage, block volumes), and platform (database configuration) services. Oracle has a shared responsibility with you to ensure that the service is optimally configured and secured. This responsibility includes hypervisor security and the configuration of the permissions and network access controls. ensure that hosts can communicate correctly and that devices are able to attach or mount the correct storage devices.
  • Network Security: You are responsible for securely configuring network elements such as virtual networking, load balancing, DNS, and gateways. Oracle is responsible for providing a secure network infrastructure.
  • Client and Endpoint Protection: Your enterprise uses various hardware and software systems, such as mobile devices and browsers, to access your cloud resources. You are responsible for securing all clients and endpoints that you allow to access Oracle Cloud Infrastructure services.
  • Physical Security: Oracle is responsible for protecting the global infrastructure that runs services offered in Oracle Cloud Infrastructure. This infrastructure consists of the hardware, software, networking, and facilities that run Oracle Cloud Infrastructure services.

Infrastructure Security

Our security model is built around people, process, tooling, and a common security “platform” of methodologies and approaches from which we build our products. We apply this model to our core security components of Security Culture, Security Design and Controls, Secure Software Development, Personnel Security, Physical Security, and Security Operations that we use to protect and secure our customers and business.

Security Culture

We believe that a dynamic security-first culture is vital to building a successful security-minded organization. We have cultivated a holistic approach to security culture in which all our team members internalize the role that security plays in our business and are actively engaged in managing and improving our products' security posture. We have also implemented mechanisms that assist us in creating and maintaining a security-aware culture.

  • Security-minded leadership: Our senior leadership is actively involved in our security planning, monitoring, and management. We define and measure ourselves against security metrics and include security as a component of our team evaluation processes.
  • Embedded expertise: To help with driving security practices within our team, we have an embedded security-engineering model with security team members sitting and working with our product development teams. This approach enables our security organization to build deep understanding of the product-development processes and system architectures. We are also able to better assist teams in solving security challenges quickly and drive security initiatives more effectively.
  • Common security standards: We actively work to integrate security into our products and operations. For example, we establish a security standards baseline. Our objective in creating this baseline is to provide a single security point of reference for business that establishes clear and actionable guidelines. The security baseline is updated frequently to incorporate learned lessons and reflect emerging business factors. We have also created a series of support materials to assist our teams in implementing security controls including reference architectures, implementation guides, and access to security experts.
  • Values of openness, constructive debate, and encouraged escalation: Security issues can be addressed only when the people who can fix them are aware of them. We believe that openness and transparency, constructive debate, and encouraged escalation make us stronger. We encourage escalation, and we work to create an environment where raising issues early and often is rewarded.
  • Security training awareness: We maintain robust security and awareness training programs that raise awareness and reinforce our security culture. We require in-depth security training sessions for all new employees and annual refresher trainings, and we provide security training that is tailored to our employees’ specific job roles. All our software developers undergo a secure development training that establishes baseline security requirements for product development and provides best practices. We also work to provide engaging and innovative forms of security awareness training such as guest speakers and interactive forums.

Security Designs and Controls

Security is integrated into our products and operations through our Oracle Cloud Infrastructure Methodology. This centralized methodology defines our approach for the core security areas that form the security foundation from which we build our products. This approach lends itself to agility and helps us apply best practices and lessons learned from one product across the business, thus raising the security of all our products.

  • User authentication and access control: Least-privilege access is used to grant access to production systems, and the approved lists of service team members are periodically reviewed to revoke access when the need can't be justified. Access to production environments requires multi-factor authentication (MFA). The security team grants MFA tokens, and tokens of inactive members are disabled. All access to production systems is logged, and the logs are stored for security analysis.
  • Change management: Oracle Cloud Infrastructure follows a defined and rigorous change management and deployment process that uses purpose-built proprietary testing and deployment tools. All changes deployed into our production environment follow a testing and approval process before they are released. This process is designed to ensure that changes operate as intended, and can otherwise be rolled back to a previous known good state to recover gracefully from unforeseen bugs or operational issues. We also track the integrity of critical system configurations to ensure that they align with expected state.
  • Vulnerability management: We use both internal penetration testing teams and external industry experts to help us identify potential vulnerabilities in our products. These exercises help us improve the security of our products, and we work to incorporate the lessons that we learn into our future development work. Oracle Cloud Infrastructure hosts undergo periodic vulnerability scanning using industry-standard scanners. Scan results are triaged to validate applicability of findings to the Oracle Cloud Infrastructure environment, and product teams apply the required patches if applicable.
  • Incident response: We have developed strong processes and mechanisms to enable us to respond to and address incidents as they arise. We maintain 24/7 incident response teams ready to detect and respond to events. Our critical staff members carry paging devices that enable us to call on the expertise needed to bring issues to resolution. We have also built a process to help us learn from our incidents. We perform root cause analysis through our Corrective Action/Preventative Action (CAPA) process. CAPAs are intended to discover process gaps and changes that the business can make after an incident. CAPAs act as a common language that we can use to reflect on an issue and capture concrete steps to improve future operational readiness. CAPAs capture the root cause of an issue, what is required to contain or fix the issue, and what steps we must take to ensure that the issue does not recur. Our leadership team reviews all CAPAs, looks for cross-organizational applications for learned lessons, and ensures that actions are implemented in a timely manner.
  • Security logging and monitoring: We have created automated mechanisms to log various security-relevant events (for example, API calls and network events) in the infrastructure, and monitor the logs for anomalous behavior. The security team tracks and triages the alerts generated by monitoring mechanisms.
  • Network security: By default, customer communications with Oracle Cloud Infrastructure services are done using the latest TLS ciphers and configuration to secure customer data in transit, and hinder any man-in-the-middle attacks. As a further defense in depth, customer commands to the services are digitally signed using public keys, to prevent any tampering. The services also deploy proven, industry-leading tools and mechanisms to mitigate distributed denial of service (DDoS) attacks and maintain high availability.
  • Control plane security: Oracle Cloud Infrastructure backend (control plane) hosts are securely isolated from customer instances by using network ACLs. Provisioning and management of customer instances are done by software agents that must interact with the backend hosts. Only authenticated and authorized software agents can successfully interact with Oracle Cloud Infrastructure backend hosts. For backend hosts, pre-production environments (for example, development, testing, and integration) are separated from production environments so that any development and test activities do not have any impact on production systems.
  • Server security and media management: Oracle has a long history of enterprise-class secure hardware development. Our Hardware Security team is responsible for designing and testing the security of the hardware used to deliver Oracle Cloud Infrastructure services. This team works with our supply chain and tests hardware components to validate them against rigorous Oracle Cloud Infrastructure hardware security standards. This team also works closely with our product development functions to ensure that hardware can be returned to a pristine, safe state after customers release the hardware.
  • Secure host wipe and media destruction: Oracle Cloud Infrastructure instances are securely wiped after customers release the hardware. This secure wipe restores hardware to a pristine state. We have re-engineered the platform with proprietary hardware components that allow us to wipe and reinitialize the hardware in a secure manner. When the underlying hardware has reached end-of-life, it is securely destroyed. Before leaving our data centers, drives are rendered unusable by using industry-leading media destruction devices.

Secure Software Development

Secure product development requires consistently applied methodologies that conform to clear security objectives and principles. We build security practices into every element of our product development life cycle. Oracle employs formal secure product development standards that are a roadmap and guide for developers. These standards discuss general security knowledge areas such as design principles and common vulnerabilities, and provide specific guidance on topics such as data validation, data privacy, and user management.

Oracle secure product development standards have evolved and expanded over time to address the common issues affecting code, new threats as they are discovered, and new use cases by Oracle customers. The standards incorporate insights and learned lessons; they do not live in a vacuum, nor are they an “after the fact” addendum to software development. They are integral to language-specific standards such as C/C++, Java, PL/SQL, and others, and are a cornerstone to Oracle's secure development programs and processes.

Security assurance analysis and testing verify security qualities of Oracle products against various types of attacks. There are two broad categories of tests employed for testing Oracle products: static and dynamic analysis. These tests fit differently in the product development lifecycle and tend to find different categories of issues, so they are used together by Oracle product teams.

Personnel Security

Our people make our business. We strive to hire the best, and we invest in and continue to develop our employees. We value training, and we require not only baseline security training for all our employees but also specialized training to keep our teams abreast of the latest security technologies, exploits, and methodologies. In addition to standard annual corporate training programs that cover our information security and privacy programs (among many others), we engage with a broad spectrum of industry groups and send our employees to specialist conferences to collaborate with other industry experts on emerging challenges. The objectives of our security training programs are to help our employees better protect our customers and products, to enable employees to grow in their knowledge areas around security, and to further our mission to attract and retain the best talent.

We work to recruit the best talent for our team as we grow, and we hire people with strong ethics and good judgment. All our employees undergo pre-employment screening as permitted by law, including criminal background checks and prior-employment validation. We also maintain performance evaluation processes to recognize good performance and help our teams and employees identify opportunities for growth. We maintain both team and employee evaluation processes, and we use security as a component of our team evaluation processes. This approach provides our teams and leadership visibility into how our teams are performing against our security standards and enables us to identify best practices and improvement areas for critical security processes.

Physical Security

Oracle Cloud Infrastructure data centers are designed for security and availability of customer data. This approach begins with our site selection process. Candidate build sites and provider locations undergo an extensive risk evaluation process that considers environmental threats, power availability and stability, vendor reputation and history, neighboring facility functions (for example, high-risk manufacturing or high-threat targets), and geopolitical considerations, among other criteria.

Oracle Cloud Infrastructure data centers align with Uptime Institute and Telecommunications Industry Association (TIA) ANSI/TIA-942-A Tier 3 or Tier 4 standards and follow a N2 redundancy methodology for critical equipment operation. Data centers housing Oracle Cloud Infrastructure services use redundant power sources and maintain generator backups to prevent widespread electrical outage. Server rooms are closely monitored for air temperature and humidity, and fire suppression systems are in place. Data center staff are trained in incident response and escalation procedures to address security or availability events that might arise.

We take a layered approach to physical security that starts with the site build. Oracle Cloud Infrastructure data center facilities are durably built with steel, concrete, or comparable materials and are designed to withstand impact from a light vehicle strike. Our sites are staffed with security guards who are ready to respond to incidents 24 hours a day, 7 days a week, 365 days a year. The exterior of the sites is secured with perimeter barriers and vehicle checks are actively monitored by a guard force and cameras that cover the building perimeter.

All persons entering our data centers must first go through a layer of security at the site entrances, which are staffed with security guards. Persons without site-specific security badges entering the site must present government-issued identification and have an approved access request granting them access to the data center building. All employees and visitors must wear visible, official identification badges at all times. There are more security layers between the entrance and server rooms that vary depending on the site build and risk profile. Data center server rooms are built with other security layers including cameras that cover server rooms, two-factor access control, and intrusion-detection mechanisms. Physical barriers are in place to create isolated security zones around server and networking racks that span from the floor (including below the raised floor where applicable) to the ceiling (including above ceiling tiles where applicable).

Access to Oracle Cloud Infrastructure data centers is carefully controlled and follows a least-privilege access approach. Authorized personnel must approve all access to server rooms and access is granted only for the necessary period. Access usage is audited, and data center leadership periodically reviews access provisioned within the system. Server rooms are isolated into secure zones that are managed on a zone-by-zone basis, and access is provisioned only for those zones required by personnel.

Security Operations

The Oracle Cloud Infrastructure Security Operations team is responsible for monitoring and securing the unique Oracle Cloud Infrastructure hosting and virtual networking technologies. The team works and trains directly with the Oracle engineers who develop these technologies to use the unique security and introspection capabilities they provide.

We monitor emerging internet security threats daily and implement appropriate response and defense plans to address risks to the business. When we determine that urgent changes are recommended that are within the scope of the customers' responsibilities, we issue security alert bulletins to those customers to ensure their protection.

In the case of a detected or reported security issue that affects Oracle Cloud Infrastructure servers or networks, Security Operations staff is available 24/7 to respond, escalate, or take required corrective action. When necessary, we will escalate and coordinate with external parties (including network and hosting service providers, hardware vendors, or law enforcement) to protect Oracle Cloud Infrastructure, our customers, and our network's security and reputation.

All actions performed in response to a security issue by the Security Operations team are done according to our documented process, and are logged in accordance with compliance requirements. Care is always taken to protect the goals of service and data integrity, privacy, and business continuity.

Customer Data Protection

Data Rights and Ownership

Oracle Cloud Infrastructure customers retain all ownership and intellectual property rights in and to their content. Customer data protection is critically important, and we strive to be transparent with our data protection processes and law enforcement requests that we might receive.

Data Privacy

Oracle Cloud Infrastructure has features that help customers align with common data privacy principles. See Oracle Cloud Infrastructure Privacy Features

Law Enforcement Requests

Except as otherwise required by law, Oracle promptly notifies customers of any subpoena, judicial, administrative, or arbitral order of an executive or administrative agency or other governmental authority that it receives and which relates to the personal data Oracle is processing on the customer’s behalf. Upon customer request, Oracle provides customers with reasonable information in its possession relevant to the law enforcement request and any assistance reasonably required for them to respond to the request in a timely manner.


Oracle Cloud Infrastructure is built for enterprises. We operate under practices aligned with the ISO/IEC 27002 Code of Practice for information security controls, from which we have identified a comprehensive set of security controls that apply to our business. Oracle Cloud Infrastructure is still a new product line, and we must operate for a period of time for these security controls and our operations to undergo external audit. As an enterprise cloud, we plan to pursue a broad suite of industry and government certifications, audits, and regulatory programs.
