1. Executive overview
The packet analysis for implemented network is critical task and all possible threats and risks to network traffic are mainly identified with it. There are different tools used for network packet analysis and Wireshark is very popular because of free availability and open source nature. The provided file shows the Telnet based communication with implementation of protocols like TCP, SMTP, FTP and IMAP etc. The complete analysis of the provided network file is done to protect the sensitive data of this network and making the recommendations for fixing the security problems in the presented network. The cross platform activities of this wireshark tool are used mainly for making analysis of the provided network. The graphical front end of wireshark provides effective filtering of malicious issues and allows us to sort them in required order. The promiscuous mode of this allocation is for verification of interface controls set over the provided network. The used protocols on the provided networks are used for identification of MAC addresses, so that traffic visibility of provided network can be monitored. The network switches and respective taps are also verified for identification of malicious activities. The monitoring mode of wireshark allows easy analysis of network and provides monitoring facilities for identification of malicious traffic.
2. Security analysis for sensitive information and malicious traffic
The security analysis for sensitive information and malicious traffic is mainly completed in this task. The identification of malicious traffic is big challenge for any network implementation. As this provided network is making use of private IP, so, all other IP from the set range are creating malicious activities to this network. The packets requiring retransmission because of data loss are mainly requiring identification as; these packets can contain sensitive information. The screen shot of provided network for security analysis through wireshark is provided under:
This file shows the TCP implementation for packet exchange. The provided responses, requests, their...
