Which of the following security controls works as the totality of protection mechanisms within a computer system, including hardware, firmware, and software, the combination of which is responsible for enforcing a security policy?
Click on the arrows to vote for the correct answer
A. B. C. D.malicious software or hardware.
Maintaining the trusted computing base (TCB) is essential for security policy to be implemented successfully.
Answer: D is.
Trusted computing base (TCB) refers to hardware, software, controls, and processes that cause a computer system or network to be devoid of incorrect.
Internet Protocol Security (IPSec) is a standard-based protocol that provides the highest level of VPN security.
IPSec can encrypt virtually everything above the networking layer.
It is used for VPN connections that use the L2TP protocol.
It secures both data and password.
IPSec cannot be used with Point-to- framework.
It deals with the communications and data security problems in the emerging Internet and intranet application space.
It presents an infrastructure for (API) is an interface implemented by a software program which enables it to interact with other software.
It facilitates interaction between different software programs similar to the way the user interface facilitates interaction between humans and computers.
An API is implemented by applications, libraries, and operating systems to determine their vocabularies and calling conventions, and is used to access their services.
It may include specifications for routines, data structures, object classes, and protocols used to communicate between the consumer and the implementer of the API.
The security control that works as the totality of protection mechanisms within a computer system, including hardware, firmware, and software, is known as the Trusted Computing Base (TCB).
The TCB is the combination of hardware, firmware, and software responsible for enforcing the security policy of a system. It is the foundation on which a secure system is built, providing a secure environment for the execution of critical functions.
The TCB consists of several components that work together to enforce the security policy. These components include the hardware and firmware that control access to the system, the operating system that provides the software environment in which applications run, and the security features that are built into the system software.
The TCB also includes mechanisms for authentication, access control, and audit logging. These mechanisms are critical to ensuring that only authorized users can access the system and that all actions taken on the system can be traced back to their source.
The TCB is designed to be highly secure and tamper-resistant, with strict controls on who can modify or update the system. It is typically implemented in a dedicated hardware component, such as a secure processor, that is isolated from the rest of the system to prevent tampering.
In summary, the Trusted Computing Base (TCB) is a critical security control that provides the totality of protection mechanisms within a computer system, including hardware, firmware, and software, which work together to enforce the security policy of the system.
