Question

What is a computer security disk​

Answer 1

Answer:

Computer security, cybersecurity[1] or information technology security (IT security) is the protection of computer systems and networks from the theft of or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.

The field is becoming more significant due to the increased reliance on computer systems, the Internet[2] and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of "smart" devices, including smartphones, televisions, and the various devices that constitute the "Internet of things". Owing to its complexity, both in terms of politics and technology, cybersecurity is also one of the major challenges in the contemporary world.[3]

Information Security is the practice of securing data and information from threats to its confidentiality, integrity, or availability. That is to say, information stored in systems can be vulnerable to unintended disclosure (confidentiality). This is when someone obtains unauthorized access to information (or information systems), or when someone divulges information inappropriately (think along the lines of your doctor sharing your medical records without permission). Information can also be tampered with (integrity), and there are ramifications to this, too. For example, students tampering with their grades / records, someone tampering with an authentication system to gain unauthorized access (changing a password, basically), and so on. Then there’s availability, which is when information is just not available for the people, processes, or systems that need it when it is needed. This can be things like accidental or deliberate deletion of information, denial of service attacks, etc.
