Abstract While it is widely known that port scanning is widespread, neither the scanning landscape nor the defensive reactions of network operators have been measured at Internet scale. In this work, we analyze data from a large network telescope to study scanning activity from the past year, uncovering large horizontal scan operations and identifying broad patterns in scanning behavior. We present an analysis of who is scanning, what services are being targeted, and the impact of new scanners on the overall landscape. We also analyze the scanning behavior triggered by recent vulnerabilities in Linksys routers, OpenSSL, and NTP. We empirically analyze the defensive behaviors that organizations employ against scanning, shedding light on who ...
