As someone who works in security, you often have to deal with large quantities of information (in the form of log files, internet packets, etc).. You also likely have to design firewall rules, analyze internet traffic, or set up malware scanners.

Different software and RegEx engines will often have their own specificities, and it's best to check the official documentation pages for a full reference of the RegEx version that you are using.

One of the ways you can use RegEx is to perform complex text searches. This means RegEx is very useful during the analysis of log files: instead of searching for simple terms, you can use RegEx to quickly find more accurate results.
