Differentiate Vulnerability, Threat and Control
A computer system is composed of three important components software, hardware, and data. Each of these components acts as an asset and offers value to each and every member of the community who is affected in some means by the system. Thus, to analyze the security of the information and data-based computer systems certain ways that can harm them are also concerned.
The difference between the vulnerability, threat, and control is given as follows.
| S.No | Vulnerability | Threat | Control |
| 1. | Vulnerability is defined as a weakness in the security of the system. For example, as in the case of procedures, designs, or implementation, they can be exploited easily to cause the harm or loss to the information security. It is supposed that a system could be vulnerable to the unauthorized accessing of data or manipulating the data because the system is unable to verify the identity of the user before the user access the data. | A threat is defined as the set of circumstances to the computing system that possess the potential to cause the loss, damage, or harm to the computing system. The difference between threat and vulnerability is that there are many threats to the computing system where some can be initiated by human or some can be initiated by the computer system. | While to address to the problems caused by the penetration of attacks on a computer system, the control is used over them as a protective measure. Thus, a control is defined as a device, action, procedure, or the technique that reduces the vulnerability. |
The relationship between the threat, control, and vulnerability is defined by the statement as follows.
A threat is barrened or blocked by the control of vulnerability.
