RHEL 10.2: post-quantum, AI, and Long-Life Add-on

"Red Hat Enterprise Linux 10.2 and 9.8 strengthen security against quantum threats by integrating quantum-resistant algorithms approved by the U.S. NIST. NIST can offer organizations confidence in this area because it is known for its commitment to standards. RHEL will therefore utilize Red Hat Certificate System 11.0. This introduces quantum-resistant signatures to protect organizations against so-called “harvest now, decrypt later” attacks."

"On the security front, Red Hat is also releasing a tech preview of sealed images, a feature that operates via image mode. This allows administrators to cryptographically sign container images, ensuring that systems boot only verified images that the customer has personally approved. This is particularly useful for environments where the underlying host cannot be fully trusted."

"Another notable feature of the releases is the expansion of Model Context Protocol (MCP) servers. These are now available as a tech preview for Red Hat Satellite and as a developer preview for RHEL itself and Red Hat Lightspeed. Through these MCP servers, AI agents can securely communicate with RHEL systems, leveraging real-time data and Red Hat's built-in expertise. Administrators can thus manage their Linux environment using natural language, with automated, multi-step workflows providing support."

"In addition, Red Hat is introducing an AI-driven upgrade experience, powered by the Ansible Automation Platform. System upgrades have traditionally been difficult and time-consuming. With the new RHEL upgrade system role, available as a Red Ha"

Red Hat Enterprise Linux 10.2 and 9.8 are planned with stronger security against quantum threats by integrating NIST-approved quantum-resistant algorithms. RHEL will use Red Hat Certificate System 11.0 to add quantum-resistant signatures that help protect against “harvest now, decrypt later” attacks. A tech preview of sealed images will allow cryptographic signing of container images and ensure systems boot only verified images approved by the customer, supporting environments where the host cannot be fully trusted. For security operations, customers using CrowdStrike with Red Hat will receive more than 2,300 new malware signatures. The releases also expand Model Context Protocol (MCP) servers for secure AI agent communication, natural-language administration, and automated multi-step workflows, alongside an AI-driven upgrade experience powered by Ansible Automation Platform.
