How does the text define cyberspace?
Cyberspace generally refers to any data or resources that can be accessed via a network or the space where the internet operates.
What is the main difference between a threat and an attack in the context of computer security?

Study Notes
Computer Security and Cybersecurity
- Computer Security involves identifying, assessing, and managing vulnerabilities, threats, and attacks on a computer system.
- Cybersecurity is all the activities related to identifying, assessing, and managing vulnerabilities, threats, and attacks originating from cyberspace.
Computer Misuse
- Computer misuse is any activity during which a computer system or computer network is accessed, or its data is accessed, modified or deleted without proper authorisation.
- Examples of computer misuse include:
- Acts that cause unauthorised modification, removal, or copying of computer contents.
- Obtaining computer service without proper authorisation (e.g., music download from an illegal site).
- Accessing programs or data on a computer with the intent to commit a crime.
- Unauthorised access to a computer system.
Elements of Computer Security
- Vulnerability: Exposure to the possibility of being attacked or harmed.
- Threat: A statement of an intention to inflict harm or damage.
- Attack: Actual action that causes harm or damage.
- Countermeasure: An action to counteract a threat.
