Cyber Security Basics: What It Is and Why It Matters
Welcome to Cyber Security
What cyber security means
Cyber security is the practice of protecting devices, accounts, networks, and data from unauthorized access, damage, or disruption. It includes both technology and human behavior, because attacks often target people as much as computers.
Big picture
You do not need to be highly technical to improve your security. Many of the most effective defenses are simple habits.
What attackers usually want
Attackers often want money, data, access, or control. They may try to steal passwords, trick someone into sending money, install harmful software, or interrupt services.
