10.7 AI in Cybersecurity

AI helps defend systems by spotting unusual activity fast - but attackers use AI too.

Chapter 10: Practical Applications of AI

Security teams use AI to monitor networks and flag anomalies - like a login from an unusual place or a computer suddenly sending tons of data. It can scan far more activity than any human team.

Email filters use AI to catch phishing. In 2024 Google even reported an AI agent that found a previously unknown security bug in popular database software.

The flip side: attackers use AI for more convincing phishing messages and voice scams. So the basics still matter most: strong unique passwords, two-factor authentication and thinking before you click.

Protect yourself

Got an urgent message or call asking for money or codes - even in a familiar voice? Hang up and verify through another channel.

Key takeaways

AI spots anomalies and phishing at scale

Attackers use AI too

Basics still win: unique passwords, 2FA, verify before you trust
