Oracle Linux is an enterprise-class Linux distribution supported by Oracle and built from source packages for Red Hat Enterprise Linux (RHEL). Some of the special features of Oracle Linux include a custom-build and rigorously-tested Linux kernel called “Oracle Unbreakable Kernel”, tight integration with Oracle’s hardware and software products including most database applications, and “zero downtime patching” – a feature that enables administrators to update the kernel without a reboot.
Oracle Linux 7.5 delivers extreme performance, advanced scalability, and reliability for enterprise applications and systems. Optimized for enterprise workloads, Oracle Linux is the only operating system to offer zero-downtime updates
Oracle Linux 7.5 provide features like it support for Memory Protection Keys on recent Intel processors – CPUs provide this support through a new user-accessible register (PKRU) that contains two separate bits; ability to unlock encrypted devices connected to a network during the boot process; SSLv3 disabled in mod_ssl, this change also restricts the use of certain cryptographic cipher suites; KASLR (kernel address-space layout randomization) for KVM guests added. Btrfs continues to be fully supported in Oracle Linux 7.5 with Unbreakable Enterprise Kernel (UEK). Btrfs support is deprecated in the Red Hat Compatible Kernel.
Cognosys provides hardened images of Oracle Linux 7.5 on all public cloud i.e. AWS .
