Definition
Platform security refers to the comprehensive set of measures and practices implemented to protect the underlying infrastructure and operating environment of computing systems. It encompasses securing the hardware, operating system, firmware, and core services that applications and data rely upon. This involves establishing robust access controls, implementing secure configurations, and ensuring the integrity of system components. By safeguarding the platform, organizations can prevent unauthorized access, data breaches, and system disruptions. For instance, hardening an operating system by disabling unnecessary services and applying security patches is a key aspect of platform security. This differs from application security, which focuses on vulnerabilities within specific software programs. Understanding platform security is crucial for roles preparing for certifications like CompTIA Security+ and CISSP.
