Foundations of cybersecurity
The CIA triad, who attacks and why, the words that matter (threat, vulnerability, risk, exploit) and how social engineering targets people rather than software.
- 1 The CIA triad: confidentiality, integrity and availability
The three properties every security decision protects, what breaks each one, and how to use them as a checklist for your own devices and data.
7 分钟 - 2 The threat landscape: who attacks, and why
Cybercriminals, hacktivists, state-sponsored groups and insiders want different things and work in different ways. Knowing which ones realistically target you tells you where to spend your effort.
8 分钟 - 3 Threats, vulnerabilities, risks and exploits: the words that matter

7 分钟 - 4 Social engineering: phishing, pretexting and baiting
