Our computer systems face the risk of being plagued by powerful, feature-rich malware. Current malware exploit the vulnerabilities that are endemic to the huge computing base that needs to be trusted to secure our private information. This summary presents the trusted computing base (TCB) and the Trusted Computing Group (TCG). TCB is the collectivity of the computer’s protector, which influences the security of system. The Trusted Computing Group (TCG) is an international industry standards group. There are extensive theories about information security and technology. Providing some technology and methods that can prevent you system from being attacked by malware and controlled by unauthorized persons. At last, we introduce efficient TCB reduction.
