Security breach

A security breach is when someone unauthorized is able to access something (like your bank account, for example) that should be locked off and only available to you. It's like if a stranger broke into your house and used your stuff without your permission - it's wrong and dangerous. A security breach might mean your bank account is hacked, your credit card information is stolen, or someone is able to use your identity to make purchases or do other things without your permission. It can happen when someone creates a computer virus, gets access to your passwords, or finds a way to exploit weak spots in your computer system. Being aware of security breaches is important, so if you think one has happened to you, you should contact whoever manages your account (like your bank) and let them know.
