In this research, packet filtering methods based on DSCP code applied to the Netfilter system are used to do prevention of DHCP Starvation attacks, this method has proven to be very effective in making prevention and more efficient when applied on small scale wireless networks such as at office networks and internet cafe.The packet capture module can be used to deep dive into traffic passing a (or multiple) network interfaces. Various methods such as authentication, cryptography, and machine learning are used by researchers in preventing DHCP Starvation attacks, but the issue of effectiveness and efficiency still opens up further research opportunities.

But it turns out that there is a security threat to DHCP service, namely DHCP Starvation attacks that can be exhausting the availability of IP addresses in DHCP service so that the configuration of IP address automatically can no longer be done on the client.

For easy access to the network, DHCP service become a standard feature that must exist, because ordinary users no longer need to think about procedures for configuring IP addresses, all of which have been done automatically by the DHCP service. The use of the internet today has become a necessity, the most commonly used media to connect to the internet is a Wireless LAN network. We will also identify various attacks captured by Wireshark using this process. In this paper, an attack pattern dictionary will be created using which captured live data packets will be manually mapped in order to detect intrusions. In this paper, we will show that Wireshark can be considered not only as troubleshooting tool, network analyzer, protocol analyzer, packet sniffer but also a network intrusion detection tool because if the user has appropriate knowledge about attacks and data packets, then he could easily identify an attack by observing a specific data packet patterns. But Wireshark lacks the feature of intrusion detection. Wireshark is an important tool for the analysis of network packets. To identify intrusions on the grid, the system must have a detection engine that can detect intrusions automatically without any human intervention. This dependency also leads to various types of intrusions. It can be in the form of education, banking, research, business, journalism and many more.

Our day to- day life mostly depends on the internet. The rise of networks has increased very fastly in this modern world.
