Chapter 17. Post-installation security hardening
RHEL is designed with robust security features enabled by default. However, you can enhance its security further through additional hardening measures.
For more information about:
- Installing security updates and displaying additional details about the updates to keep your RHEL systems secured against newly discovered threats and vulnerabilities, see Managing and monitoring security updates.
- Processes and practices for securing RHEL servers and workstations against local and remote intrusion, exploitation, and malicious activity, see Security hardening.
- Control how users and processes interact with the files on the system or control which users can perform which actions by mapping them to specific SELinux confined users, see Using SELinux.
- Tools and techniques to improve the security of your networks and lower the risks of data breaches and intrusions, see Securing networks.
- Packet filters, such as firewalls, that use rules to control incoming, outgoing, and forwarded network traffic, see Configuring firewalls and packet filters.
