What is the distinction between a cyber-attack and a security breach?

A cyber-attack differs from a security breach in several ways. A cyber-attack, is an attempt to compromise a system's security. Using various types of cyber-attacks as detailed in the preceding section, attackers attempt to exploit the confidentiality, integrity, or availability of a software or network. A successful event or incident in which a cyber-attack results in the compromise of sensitive information, unauthorised access to IT systems, or service disruption is known as a security breach.

Attackers regularly test a variety of cyber-attacks on their targets in the hopes of finding one that would result in a security breach. As a result, security breaches bring to light another important aspect of a comprehensive cyber security strategy: business continuity and incident response (BC-IR). In the event of a successful cyber-attack. When a security incident occurs, Business Continuity is concerned with keeping important business systems operational, whereas Incidence Response is concerned with responding to a security breach and limiting its impact, as well as aiding the recovery of IT and business systems.

Now the concern is who is responsible to breaching the things in terms of cyber attack either security breach so it is obvious, normal human being never do the same until and unless he does not have the wide experience of cyber security courses or does not having any cyber security certification from reputed institute like careerera.com, simplilearn, greatlearning etc.
