While bro-cut is certainly an important tool in your toolbox, you can expand on your ability to analyze logs and detect a variety of interesting network events through the use of the awk program. In this talk Mark will give an intro to the syntax of the awk command and then show several examples of how awk can be used directly on logs or in a pipeline with other programs. He hopes that you find the examples provided as useful takeaways from BroCon whether you are a beginner or advanced user.
