By the close of 2016, "Annual global IP traffic will pass the zettabyte ([ZB]; 1000 exabytes [EB]) threshold and will reach 2.3 ZBs per year by 2020," according to Cisco's Visual Networking Index. While analyzing network traffic enables defenders of large organizational networks to have network situational awareness, operators of networks of even modest size struggle with building a comprehensive view of network activity. In this blog post, Shimeall examines two different approaches for analyzing network security using and going beyond network flow data to gain situational awareness to improve security.
