Big Data Analytics is transforming the landscape of cyber security by enhancing threat detection, prevention, and response. With the explosion of data from various sources like IoT devices, cloud platforms, and user activity logs, traditional security systems often struggle to keep up. Big Data enables security professionals to analyze massive volumes of structured and unstructured data in real-time to identify anomalies, detect cyber threats, and predict future attacks. Organizations are increasingly adopting Big Data tools to stay ahead of evolving threats and improve incident response times. As the demand grows, professionals trained in both data analytics and cyber security—often from institutes like SKILLOGIC—are becoming highly sought after in the industry.
