Final answer:
Securing big data requires robust security measures such as authentication and authorization mechanisms. This is to protect against threats such as identity theft which can result from data breaches experienced by major organizations.
Step-by-step explanation:
Securing big data involves ensuring that data networks are sufficiently secured via authentication and authorization mechanisms. In light of the large-scale data breaches that organizations like Target, JP Morgan, and Verizon have experienced, it's evident that robust security measures are imperative to protect against the threat of identity theft and safeguard personal information.
Increase in security measures for individuals includes the utilization of two-factor authentication, the creation of stronger passwords, and education to avoid phishing scams and other types of online fraud. Similarly, companies and governments must bolster their website security to prevent unauthorized access to sensitive data.
