Demystifying Regular Expressions

$7.00

Whether you’re reading and writing IDS rules, searching in a SIEM, or using grep to search through files, this course will help you get comfortable writing and interpreting regular expressions. 

I hate when I know the data I want is there, but I just can’t find it. This happened to me a lot early in my career, particularly when writing Snort signatures or searching for things in a SIEM. Most tools have limited native matching capability, so it always came down to writing regular expressions to dig deeper. I avoided them like the plague.
