Learning Objectives
- Define cybersecurity in plain language.
- Explain threats, vulnerabilities and risk.
- Describe confidentiality, integrity and availability (CIA).
- Recognise differences between personal and business cybersecurity needs.
Build a clear foundation in how cyber threats, vulnerabilities and risk affect people and organisations.
Without a foundation, it is easy to focus on tools instead of outcomes. Strong cyber decisions begin with understanding risk and priorities.
For both home users and businesses, prevention is usually cheaper and less stressful than recovery.
Cybersecurity is the practice of reducing harm from digital threats. A threat is something that might cause harm. A vulnerability is a weakness that could be exploited. Risk is the chance and impact of harm happening. CIA helps frame protection goals: keep information private (confidentiality), accurate (integrity), and available when needed (availability).
A threat is a possible harmful event or actor. A vulnerability is a weakness that can be exploited.
Availability, because backups help you restore access to information and systems.
Not always. Business environments usually need stronger governance, access control and continuity planning.
