Introduction to Cybersecurity: Concepts and Principles

Learning Objectives Define cybersecurity, threat, vulnerability, and defense mechanism. Identify at least three common cyber threats like phishing, malware, and weak passwords. Explain the three principles of the CIA Triad (Confidentiality, Integrity, Availability) using a simple analogy. Describe two defense mechanisms, such as creating strong passwords and using two-factor authentication. Apply the 'Principle of Least Privilege' to a simple, real-world scenario. Analyze a sample message to identify the signs of a phishing attempt. Have you ever built an amazing fort and made secret rules so only your friends could get in? 🤔 Cybersecurity is like building a super-strong digital fort for your online information! In this lesson, we'll become digital detective...

TermDefinitionExample CybersecurityThe job of protecting computers, networks, and data from being attacked, damaged, or stolen by digital bad guys.Using a password to lock your phone is a simple form of cybersecurity. ThreatAnything that has the potential to harm your digital information or devices.A computer virus that tries to steal your passwords is a threat. VulnerabilityA weakness or a hole in your security that a threat can use to get in.Using 'password123' as your password is a big vulnerability because it's so easy to guess. PhishingA trick used by attackers to make you give them your personal information, like passwords or credit card numbers, by pretending to be someone you trust.You get an email that looks like it's from your favorite game company, asking yo...

The CIA Triad Confidentiality, Integrity, and Availability These are the three main goals of cybersecurity. Confidentiality means keeping secrets secret (only authorized people can see data). Integrity means making sure data is not changed or messed with. Availability means making sure you can access your data when you need it. Principle of Least Privilege Give only the minimum level of access needed to do a job. Use this principle when sharing files or giving permissions. Don't give someone full 'admin' control if they only need to read a document. This limits the damage someone can do if their account gets compromised. Defense in Depth Use multiple layers of security. Don't rely on just one defense. Think of a castle: it has a moat, a high wall,...
