As a missing person investigator, we can use this data to find a persons home address, phone number, password information, birth date, secondary email addresses and more. ElasticSearch can help us store and search billions worth of breach data. ElasticSearch is an open-source, distributed, RESTful, search engine. ES (ElasticSearch) uses JVM and is built on top of Apache Lucene. ES is great for indexing large amounts of data, sifting through a large result set, and analyzing data. In this video I will demostrate how to take breach data, convert it to ES-compliant JSON, import it, and then query for results. In this video I will show you how to ru...
