1.3 Overview of Oracle Linux Security

Oracle Linux has evolved into a secure enterprise-class operating system that can provide the performance, data integrity, and application uptime necessary for business-critical production environments.

Thousands of production systems at Oracle run Oracle Linux and numerous internal developers use it as their development platform. Oracle Linux is also at the heart of several Oracle engineered systems, including the Oracle Exadata Database Machine, Oracle Exalytics In-Memory Machine, Oracle Exalogic Elastic Cloud, and Oracle Database Appliance.

Oracle On Demand services, which deliver software as a service (SaaS) at a customer's site, via an Oracle data center, or at a partner site, use Oracle Linux at the foundation of their solution architectures. Backed by Oracle support, these mission-critical systems and deployments depend fundamentally on the built-in security and reliability features of the Oracle Linux operating system.

Released under an open-source license, Oracle Linux includes the Unbreakable Enterprise Kernel that provides the latest Linux innovations while offering tested performance and stability. Oracle has been a key participant in the Linux community, contributing code enhancements such as Oracle Cluster File System and the Btrfs file system. From a security perspective, having roots in open source is a significant advantage. The Linux community, which includes many experienced developers and security experts, reviews posted Linux code extensively prior to its testing and release. The open-source Linux community has supplied many security improvements over time, including access control lists (ACLs), cryptographic libraries, and trusted utilities.
