In which of the following forms of bulk data collection are large amounts of data...

In the context of bulk data collection for threat intelligence, data is often initially collected in an unstructured form from multiple sources and in various formats. This unstructured data includes information from blogs, news articles, threat reports, social media, and other sources that do not follow a specific structure or format. The subsequent processing of this data involves organizing, structuring, and analyzing it to extract actionable threat intelligence. This phase is crucial for turning vast amounts of disparate data into coherent, useful insights for cybersecurity purposes.References:
