Oracle Cloud Infrastructure security

Isolated network virtualization

Oracle Cloud Infrastructure uses custom-designed SmartNIC to isolate and virtualize the network. Using the SmartNIC, Oracle Cloud Infrastructure prevents any malware within a compromised instance from moving to other customers’ instances.

Oracle Cloud Infrastructure Differentiators
  • Isolates and virtualizes the network with SmartNIC
  • Isolates hardware and software from the cloud host
  • Prevents network attacks on customer tenants

Reduce risk from firmware-based attacks with Hardware Root of Trust

Protect customer tenants with a highly secure firmware installation. Use the hardware-based root of trust card that is manufactured to Oracle specifications to guarantee a clean firmware installation for each new customer tenant.

Experience the world’s first autonomous operating system

Oracle Autonomous Linux, combined with OS management service, executes automatic patch updates and tuning, improving security, downtime, and IT staff productivity.

Oracle Cloud Infrastructure Differentiators
  • Cost effective, compatible, and complete
  • Highly secure and reliable
  • Highly available and scalable
  • Manageable and automated

Protect applications from malicious traffic

Oracle Web Application Firewall is a cloud-based, PCI-compliant, global security service that protects applications from malicious and unwanted internet traffic.

Oracle Cloud Infrastructure Differentiators
  • Protection
  • Access
  • Bot management

Control who has access to your cloud information

Oracle Cloud Infrastructure identity and access management service lets you control who has access to your cloud resources, what type of access they have, and to which specific resources. Manage complex organizations and rules with logical groups of users and resources and simple-to-define policies.

Oracle Cloud Infrastructure Differentiators
  • Manage users and access
  • Secure by design
  • Define groups and permissions

Encrypt your data using the keys you control

Oracle Cloud Infrastructure Key Management is a managed service that enables you to encrypt your data using keys you control.

Oracle Cloud Infrastructure Differentiators
  • Protect your keys
  • Use the managed service
  • Enhance compliance

Proactively manage cloud security posture

Automatically set up and enforce security policies in Oracle Cloud Infrastructure with Oracle Cloud Guard and Security Zones.

Protect applications and workloads

Oracle CASB (Cloud Access Security Broker) provides visibility into your entire cloud stack and the security automation tools your IT team needs.

Eliminate risk from vulnerabilities

Assess and monitor cloud hosts for new, unpatched vulnerabilities and open hosts.

Provide restricted and time-limited secure access to private hosts

Oracle Cloud Infrastructure (OCI) Bastion service enables customers to have access to private hosts without deploying and maintaining a jump host. The service removes the need for a public IP for bastion access, eliminating the hassle and potential attack surface from remote access.

Oracle Cloud Infrastructure differentiators:
  • Secure access to private hosts
  • Simplified SSH access
  • Centralized visibility and control for SSH sessions

Create, deploy, and manage certificates in Oracle Cloud Infrastructure

Adopt a flexible private certificate authority (CA) hierarchy to create private CAs. Avoid the error-prone, manual certificate management process with the new OCI Certificates service.

Ensure separation of data and workloads

Oracle bare metal instances support applications requiring high core counts, large amounts of memory, and high memory bandwidth. Bare metal compute instances provide customers with exceptional isolation, visibility, and control.

Oracle Cloud Infrastructure Differentiators
  • Experience high performance
  • Utilize elastic and on-demand compute
  • Better manage security and control

A global approach to compliance

Oracle continuously pursues programs that maintain compliance with global, regional, and industry-specific certifications.

Security that meets stringent government requirements

Oracle Cloud Infrastructure government regions provide public sector entities with best-in-class security and industry-leading price-performance.

Adhere to data privacy requirements

Oracle helps customers comply with data privacy principles with Oracle Cloud Infrastructure privacy features.

Oracle Cloud Infrastructure Should Be on Your Short List of Cloud Service Providers

Jay Bretzmann, IDC Program Director, Security Products

When evaluating a cloud environment, we look to an old saying in the IT industry about project management systems called the “Iron Triangle,” where the desire is to create a solution that's good, fast, and cheap. For today's cloud reality, the Iron Triangle would more appropriately be: good, fast, and easy. Easy recognizes that we have a scarcity of IT talent. Saving pennies of hard cost while creating work for scarce IT people results in softer costs that strangle returns on investment. Using IDC's recently completed lab validation study of the Oracle Cloud Infrastructure (OCI), let's consider the selection of OCI from the monocle of ROI impacts on people.
