Writing Regular Expressions (Regex) is a versatile skill set to have across the IT landscape. Regex has a number of information security related uses and applications. We are going to provide an overview and work through examples of writing Regex as a group for pattern matching and file content analysis using sample threat feed data in this presentation. Along with a healthy dose of motherly advice, we cover Regex syntax, character classes, capture groups, sub-capture groups, and quantifiers. Whether Regex is something completely new or worth brushing up on, this talk is geared toward you.
