Cyber security and countermeasure

Cyber security is when people protect their computers, phones, and other technology from the bad guys that want to do bad things with them. Countermeasures are things people do to prevent cyber security problems. Things like using strong passwords, not clicking on suspicious links or attachments, and using anti-virus software to scan your computer regularly are all examples of countermeasures. Cyber security and countermeasures work together to keep our technology safe and make sure the bad guys don't break in or do bad things with our stuff.
