Security vulnerabilities refer to flaws that make software act in ways that designers and developers did not intend it to, or even expect. Research in vulnerability analysis aims to improve ways of discovering vulnerabilities and making them public to prevent attackers from exploiting them.
Penetration testing replicates the actions of an external or/and internal cyber attacker/s that is intended to break the information security and hack the valuable data or disrupt the normal functioning of the organization. So, with the help of advanced tools and techniques, a penetration tester (also known as ethical hacker) makes an effort to control critical systems and acquire access to sensitive data.
On the other hand, a vulnerability assessment is the technique of identifying (discovery) and measuring security vulnerabilities (scanning) in a given environment. It is a comprehensive assessment of the information security position (result analysis). Further, it identifies the potential weaknesses and provides the proper mitigation measures (remediation) to either remove those weaknesses or reduce below the risk level.
Black hat hackers are malicious hackers, sometimes called crackers. Black hats lack ethics, sometimes violate laws, and break into adversary computer systems with malicious intent, and they may violate the confidentiality, integrity, or availability of an organization's systems and data.
