Cybersecurity Fundamentals and Common Attack Defenses

A message arrives. It looks like your boss, or your bank, or a vendor you pay every month, and it wants you to act right now. Most security advice would have you memorize a hundred attack names and hope the right one comes to mind. This course does the opposite: it gives you one move you can make every time. Recognize what you're looking at. Judge how much it actually matters. Apply the right protection. Take the correct first step — and know who to tell. You'll run that loop on the situations that really happen to people and small businesses: the phishing email, the invoice with new bank details, the reused password that unlocks everything, the laptop left in a taxi, the morning the files are all encrypted. Along the way the myths get corrected, because believing them is what gets people caught. The padlock doesn't mean a site is safe. Changing your password every 90 days makes it weaker, not stronger. Antivirus alone isn't enough, "we're too small to be a target" is exactly backwards, and the strongest single thing most people can do — turn on the right kind of multi-factor authentication — takes minutes. You'll also learn to size up your own risk so effort goes where it counts, and to have a plan ready for the bad day instead of improvising in a panic. No prior background, no jargon for its own sake, no fear-mongering — just the real frameworks professionals use, taught as habits you can actually keep. Whether you're protecting a team, a business, or just yourself, you'll leave able to handle the moment instead of freezing.
