For a decade now, many Network Forensics Analysts, Network Security Engineers, and Cyber security Professionals have pondered that most interesting of questions: What do “they” know about my network? From time to time over the years, discussions related to determining what external entities may know about determining the attack surface of a network occur and then fizzle out. Often, organizations collect and store a great deal of data to piece together a defensive view of a network but do not piece together what external entities know about or have shown interest in on the same network. Big Data offers the potential to evaluate this question in ways that were unimaginable just five years ago. New technologies and techniques enable organizations to evaluate the question of what is the known attack surface of my network. I addressed this question head-on using a variety of cyber security data sets, enrichment techniques, Cloudera CDH 4 (Hadoop distribution), and Platfora: a relative newcomer that is one of the most powerful tools I have worked with in some time.
