Fragmented packet scanning is a technique used to split the crafted packets into smaller pieces, potentially evading detection by making the traffic appear less suspicious to anomaly detection systems that are expecting larger packets indicative of a scan or attack. On the other hand, performing a full connect scan without any modifications can be easily detected due to the establishment of a full TCP connection. While using common ports may help evade some simplistic forms of detection, it is less effective against anomaly detection systems. ICMP echo requests are typically used for simple host discovery and are not as effective for evading sophisticated detection systems.
