Various people or parties are vulnerable to cyber attacks however, different groups are likely to experience different types of attacks more than others. Vulnerabilities can be researched, reverse-engineered, hunted, or exploited using automated tools or customized scripts. An exploitable vulnerability is one for which at least one working attack or exploit exists. Most of the vulnerabilities that have been discovered are documented in the Common Vulnerabilities and Exposures (CVE) database. While most aspects of computer security involve digital measures such as electronic passwords and encryption, physical security measures such as metal locks are still used to prevent unauthorized tampering.Ī vulnerability is a security weakness in the design, implementation, operation, or internal control of a computer or system. Security is of especially high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution, elections, and finance. Cybersecurity is one of the most significant challenges of the contemporary world, due to both the complexity of information systems and the societies they support. It is also significant due to the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). The field is significant due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi.
