What is Cybersecurity?

” Computer security, also known as cybersecurity or IT security, is the protection of computer systems from the theft and damage to their hardware, software or information, as well as from disruption or misdirection of the services they provide.

Cybersecurity includes controlling physical access to the hardware, as well as protecting against the harm that may come via network access, data, and code injection.  Also, due to malpractice by operators, whether intentional, accidental, IT security is susceptible to being tricked into deviating from secure procedures through various methods.

The field is of growing importance due to the increasing reliance on computer systems and the Internet,  wireless networks such as Bluetooth and Wi-Fi, and the growth of “smart” devices, including smartphones, televisions and tiny devices as part of the Internet of Things.

A vulnerability is a weakness in design, implementation, operation or internal control. As they are discovered many vulnerabilities are documented in the Common Vulnerabilities and Exposures (CVE) database. An exploitable vulnerability is one for which at least one working attack or “exploit” exists. Vulnerabilities are often hunted or exploited with the aid of automated tools. To secure a computer system, it is important to understand the attacks that can be made against it.” https://en.wikipedia.org/wiki/Computer_security
