Why is security a software issue?
they use to obtain unauthorized access and launch attacks, can compromise systems by exploiting software defects. The security of computer systems and networks has become increasingly limited by the quality and security of their software. Security defects and vulnerabilities in software are common.
Is weakness in the security system?
In computer security, a vulnerability is a weakness which can be exploited by a threat actor, such as an attacker, to cross privilege boundaries (i.e. perform unauthorized actions) within a computer system. A security risk is often incorrectly classified as a vulnerability.
Can a system be secure but not reliable?
Consequently, security measures are considered as reliability requirements, where there are many similarities in the requirements for both reliability and security, systems cannot be reliable if security measures are not considered as a part of a system.
Can a system be reliable but not secure can a system be secure but not reliable?
There could be systems which are reliable but unsafe, and there could be systems which are safe but unreliable. However, even more problematic is the extension of the concepts to other type of system components such as the Humans and Organizations. Here reliability based approaches simply do more harm then any good.
