Webtakes relatively long time to detect an abnormal packet and suspicious cyber attacks. This means that a real-time network protection is hardly implemented. Second, a server or system running a NIDS software consumes a large amount of resource that results in the packet loss even in a low-bandwidth network environment [7]–[10]. IP fragmentation attacks are a kind of computer security attack based on how the Internet Protocol (IP) requires data to be transmitted and processed. Specifically, it invokes IP fragmentation, a process used to partition messages (the service data unit (SDU); typically a packet) from one layer of a network into multiple smaller payloads that can fit within the lower layer's protocol data unit (PDU).
