Research papers like Practical Automated Detection of Stealthy Portscans analyze how these fixed thresholds—like 30 probes—are often too easy for attackers to evade by slowing down their scan rate. "kportscan 30 upd" does not appear to refer

Why would an administrator or penetration tester run this specific command? If the port is open: The service (e
