AKA (security)

Security is like having a big, strong lock on your bike so nobody can steal it. Just like your bike, there are things and information that need to be protected from naughty people who want to take them away, hurt them or spy on them. Security makes sure that only the people who are allowed to see or use something can do it, and that everything is safe from bad guys.

Security can be many things like passwords and special codes, firewalls, alarms or even guards. It is important to have security to make sure everything is safe and nobody can take something from us or hurt us.
