What is a data breach?

Hello, my name is Levi, I'm going to discuss the issue of data breaches. 


What is a data breach?

A data breach is where unauthorised user gain access to sensitive, protected or confidential, information, often with malicious intent. This can involve numerous forms of information, this can include, personal, finical, account credentials, health information, intellectual property. This can often happen through means such as hacking, system vulnerabilities, insider leaks, theft from the physical world, or even from accidents. 

This can lead to all sorts of issues, such as identity fraud, financial loss, damage to reputation and legal consequences.



Yahoo Data breach - 2013-2014

Well known as one of the biggest data breaches in history, it feels very important to discuss this data breach due to the severity of it, this affected 3 billion user created accounts, leading to stolen user information and account credentials. From names, email addresses, passwords, date of birth, and even security questions, this was only publicly disclosed in 2016. 

The consequences, were the loss of data, the loss of trust and reputation in user's security, the financial effects of trying to mitigate the effect of the breach, improving security measures and legal fees.
