To truly appreciate what RHEL 10 offers, it’s essential to compare it with the capabilities of previous major releases like RHEL 8 and RHEL 9. This comparison helps IT leaders make informed decisions about whether and when to upgrade.
Modern security enhancements in RHEL 10
Security is a fundamental component of enterprise infrastructure, and RHEL 10 significantly improves upon the frameworks introduced in prior versions. While previous releases laid the foundation for SELinux improvements and encryption, RHEL 10 builds a more dynamic and adaptable security model.
Streamlined SELinux management
SELinux has historically been complex for system administrators to manage, often requiring detailed policy customization and troubleshooting. In RHEL 10, SELinux becomes easier to configure through more user-friendly tools and integrated diagnostics. The policy enforcement mechanism is more transparent, with better default policies and reduced false positives during audits.
Improved troubleshooting options help administrators quickly identify and resolve conflicts, while graphical tools in the web console make SELinux configuration more accessible. This stands in contrast to earlier versions where SELinux debugging often required extensive log parsing and command-line expertise.
Integrated compliance roles
RHEL 10 introduces ready-to-use system roles focused on security compliance. These roles allow administrators to enforce standards such as CIS benchmarks or STIG profiles using automated playbooks. Rather than relying on third-party tools or manual interventions, organizations can use these integrated roles to ensure that their environments meet industry compliance requirements.
This contrasts with RHEL 8 and 9, where achieving compliance often meant writing custom Ansible playbooks or scripts. The ability to apply predefined, tested configurations saves time and reduces human error.
Updated cryptographic standards
Encryption is critical to protecting data at rest and in transit. RHEL 10 supports modern cryptographic algorithms, including those compliant with the latest FIPS guidelines. TLS 1.3 is enabled by default, offering better performance and improved security over TLS 1.2. In addition, updated versions of GnuTLS and OpenSSL improve efficiency and reduce vulnerabilities.
Older versions like RHEL 8 began adopting TLS 1.3, but RHEL 10 treats it as a foundational standard. Its system-wide cryptographic policies are easier to apply and adjust, helping administrators enforce consistent security settings across all applications and services.
Improved authentication mechanisms
User authentication has also been improved. RHEL 10 integrates better with identity management solutions and supports multi-factor authentication more natively than earlier releases. This aligns with modern zero-trust architectures, making it easier to secure remote access and enforce access control policies.
These changes offer stronger default security while giving enterprises more flexibility in designing their authentication strategy. RHEL 8 and 9 provided basic integration with LDAP and Kerberos, but RHEL 10 extends these capabilities with enhanced token-based authentication and easier integration with enterprise SSO platforms.
