Regular Expressions (RegEx) SE-023

The Security training will be deliver by Kereon, our Accredited EC-Council partner.

Course Overview

Information are sometimes located in very large files (big data). Retrieving a specific data in such context cannot be done efficiently via a line-by-line examination. A regular expression describes the format of the data to be retrieved. By using a regular expression, one can retrieve the specific data and all other having the same format. This training is unique, covering in depth a subject barely covered, if covered, during university, college, and digital investigation courses.
