Practical, defensive digital-safety skills for everyday life — the kind that actually keep you from being hacked or scammed. Learn to spot phishing emails and text scams (urgency, mismatched links, requests for codes or gift cards), build strong unique passwords and use a password manager, turn on two-factor authentication (and why an app or key beats SMS), recognize malware and the importance of updates, protect your privacy and data, browse safely (HTTPS, public Wi-Fi risks), and shut down social-engineering tactics like pretexting and the "tech support" call. Grounded in consensus guidance (NIST, the FTC scam taxonomy, CISA). Defensive only — how to protect yourself, never how to attack others. Educational general guidance, not a substitute for professional incident response.
