Detection of Sparse Anomalies in High-Dimensional Network Telescope Signals. (arXiv:2211.04918v1 [cs.CR])

Network operators and system administrators are increasingly overwhelmed with
incessant cyber-security threats ranging from malicious network reconnaissance
to attacks such as distributed denial of service and data breaches. A large
number of these attacks could be prevented if the network operators were better
equipped with threat intelligence information that would allow them to block or
throttle nefarious scanning activities. Network telescopes or "darknets" offer
a unique window into observing Internet-wide scanners and other malicious
entities, and they could offer early …
