In cybersecurity as in sports, teamwork makes the dream work. In a world where security analysts can feel constantly bombarded by threat actors, banding together to share information and strategies is increasingly important. Over the last few years, security operations center (SOC) analysts started sharing open source Sigma rules to create and share detections that help them level the playing field.

A structured approach to incident response enables you to create consistently repeatable processes.

It’s a warm, sunny day as you lie in the sand under a big umbrella. Suddenly, you feel the waves crashing against your feet, only to look down and see numbers, letters, usernames, and timestamps. You try to stand up, but you feel the tide of big data pulling you under… With a jolt, you wake up, realizing that you were having another nightmare about your security Data Lake and analytics.

Your Domain Name System (DNS) infrastructure enables users to connect to web-based resources by translating everyday language into IP addresses. Imagine going into a restaurant, in the age before the internet, only to find that the staff speaks and the menu is written in a different language from yours. Without some shared communication form, you can’t order dinner, and they can’t give you what you want.
