Definition - What does Platform Security mean?
Platform security refers to the security architecture, tools and processes that ensure the security of an entire computing platform.
It uses bundled/unified security software, systems and processes to enable the security of a computing platform's hardware, software, network, storage and other components.
Techopedia explains Platform Security
Platform security enables the securing of an entire platform by using a centralized security architecture or system. Unlike a layered security approach, in which each layer/system manages its own security, platform security secures all components and layers within a platform. This enables the elimination of individual security measures and use of multiple applications/services to secure different layers of an IT environment.
The security implemented in smartphones and/or devices with embedded software, such as gaming consoles, are common examples of platform security.
