What is Data Breach?
Once upon a time there was a farmer who had large field filled with precious crops. The farmer worked hard to tend his to crops and protect them from out side threats.
Once a day, while the farmer was away from his field, a group of thieves snuck in and stole some of the crops.
The farmer returned to his field to find that his precious crops had been tampered with and some had even been taken away, He was devastated and couldn’t understand how his had happened. He had put so much effort into protecting his crops, but somehow the thieves had managed to breach his defences.
In a similar way a data breach occurs when a malicious party gains unauthorized access to sensitive information stored.
Just like a farmer’ company, and Organization work hard to protect their valuable data from outside threats, but sometimes those efforts are not enough to prevent a breach.
The consequences of a data breach sever, including financial losses, damage to reputation, and even legal action, just as the farmer learned from his experience and strengthened his security measures to protect his crops, Organization can also learn form data breaches and take steps to improve their cyber security practice and prevent future breaches
