Sysscan Scanner Request

Sysscan/masscan is a very fast TCP port scanner not a URL scanner, hence ASM is not capable of detecting it, but it is already protecting your websites because what F5 is very good at is dropping packets on ports it is not listening on. If sysscans does hit ports 80/443 then F5 LTM will simply reset the connection without any impact on the backend application. You can tell your boss to relax as this was not a web attack, buct a port scanner. Pretty simple to block on the upstream network firewall as well..
