Most things can be improved upon, even secure-by-default Oracle Linux, as Ginny Henningsen demonstrates in her two-part series on hardening the operating system's defenses against exploitation by outsiders. The first part discussed hardening the OS itself by removing unused software packages and minimizing network services, performing comprehensive administrative procedures, and creating the comprehensive security architecture and governance framework that is critical for ensuring the integrity and availability of systems and data. Such a framework, Henningsen writes, includes documented security policies, routine system monitoring and management procedures, and periodic security evaluations. It's important to review administrative practices periodically and to take end-to-end security precautions to determine what additional safety measures can be taken to protect your Oracle Linux and other enterprise IT systems. In part 2 Henningsen reviews procedures and frequently used tools that administrators can employ to safeguard Oracle Linux systems, monitor potential threats, and detect compromise in the event it does occur.
