Wireshark filters2/3/2024 ![]() If you are working professionally, or you wanted to submit the PCAP for the analysis to your seniors, managers, or any others, you cannot simply give the PCAPs and ask them to filter on their own, that doesn’t sound professional. There would be lots of packets that must have been collected as of now. Now that we have seen the 3-way TCP handshake process and the SSL handshake (sending of the CLIENT and SERVER packets in the Wireshark). Once that is accepted by the server, the server will send the SERVER packet, which consists of their certificates, algorithms, and ciphers. ![]() Once established It starts sending the CLIENT HELLO packet and this packet contains a lot of information such as Certificates, cipher, and algorithms that the system is using. Now It uses TCP protocol which guarantees packet delivery and error-free data. This ensures that the TCP way handshake is established successfully for further communication. Basically, this is the 3-way TCP Handshake process, where the system sends the SYN Packet flag set to 1 then, the SYN + ACK flag set to 1, Followed by the ACK flag set to 1. Now, this can also be seen on the Wireshark in the Client Hello Packet. Represent that whatever is before the dot would be classified under. Let us take an example, if you wanted to browse then the SNI would be ”. You’ll then see a menu of additional options. Once you select the IP address, right-click, and then select the Apply As Filter option. Alternatively, you can highlight the IP address of a packet and then create a filter for it. ![]() Server Name Indication is one of the important things that every server has. Figure 11: Applying a filter to a capture in Wireshark. Wireshark comes up with so many options that you can explore, it helps you to analyze which of the SNI (Server Name Indication) is having the largest traffic so that you can filter the TCP session of that captured file. Now, this traffic would be any, if it is flowing from the internet to your system Or system to the internet. If a packet meets the requirements expressed in your filter, then it is displayed in the list of packets. Wireshark is the Network analyzer tool that analyzes the traffic that is being captured. Wireshark and TShark share a powerful filter engine that helps remove the noise from a packet trace and lets you see only the packets that interest you. Wireshark is used in Information Technology Industries for a while now, it is a free software tool that can perform actions beyond the level. It is so popular and so convenient to use, only if you know what exactly you want to perform. Wireshark is one of the most used tools by Cyber Security Experts around the Globe.
