The USB bus is the most common way of connecting peripherals to personal computers. The goal of this thesis is to create an application which analyzes communication between a device connected to this bus and a computer. The application is capable to readably display analyzed data, with specific focus on HID class devices. The application implements semantic analysis of a subset of HID devices consisting of mice, keyboards and joysticks. The methods that the application uses to visually represent data are inspired by already existing applications, where our application combines them and impoves their capabilities to achieve better results. Notable part of the application is its ability to parse HID Report Descriptor, to accomplish easier addition of new HID devices for semantic analysis. Overall design of the application is general enough to allow simple addition of analysis for other USB classes. 1

The Packet Analyzer is a Unix user program that filters a network packet and reports its contents. The term Universal is used to indicate that this program is not limited to a particular protocol stack nor is it limited by the number of layers. The software has an intuitive window-based graphical interface and is mouse driven. The input is a Hex packet stream read from user designated files and the output is the filtered packet, which can be viewed either online or offline. The code is written in ''C'' and the graphical user interface was built using devguide, the OpenWindows Software Developer''s Guide. Packets are defined with the aid of a simple scripting language called the Packet Definition Language (PDL) [1] and [2]. The PDL has constructs that support the layered architecture concept of networks. The user can inspect the packet at any layer using filters. Filters are built up from filter clauses, written in a simple scripting language called the Filter Definition Language (FDL) [1] and [2]. The package has a number of supplementary services that support the main activity of filtering packets. The user has the capability of saving and naming the current configuration of packet definitions and filters. The user can return to this configuration by name, thus saving time. The user can build and edit both filters and packet definitions on the fly.

This paper presents the implementation of online acquisition software for electrocardiogram (ECG) signals. This program is based on the Python language and it allows the adaptation of a commercial offline signal acquisition board into an online signal acquisition board. Here, the concept of online acquisition is applied when the signal can be analyzed in short time intervals, such as a few seconds. The developed system is divided into two parts: the acquisition module; and the graphical user interface (GUI). The acquisition module is responsible for recording and processing the raw signal, making it available to the graphics module. The developed structure allows the algorithm to be used in more complex applications, abstracting the acquisition logic. Furthermore, the acquisition module has acquisition settings, defined by the user when initializing the module. This work presents a simple example of an application using the module. In this case, the system stores the information from the acquisition module and constantly plots it on the screen. The program also integrates settings available by code, using command-line arguments. Therefore, the developed system presents itself as a powerful tool for online ECG signal acquisition, allowing the use of the board in human-machine interfaces.

Network demands are expanding dramatically, especially in educational sectors where systems are acting in a non-tradition network environment. Most of the services are published on the cloud so students can access teaching or learning materials directly; such demand is a heavy burden to systems administrators who needs to monitor critical educational services around the clock. However, such solutions need efforts, money, time, and space to be built; in this paper, the Internet of Things (IoT) is proposed as a small and cheap device that can be installed and configured to analyze packets locally for each service while analyzed logs can be synced simultaneously to have a complete view about systems behavior from any location for the education’s system. Based on the results, the proposed approach showed a significant solution for the heavy demands on the educational system. Moreover, the results showed that the presented approach is more efficient when compared to the state of art packet analysis and monitoring approaches.

Nowadays it is common the adoption of network traffic analysis tools as a protection against possible cyberattacks, but Attackers have become increasingly skilled at building more and more complex attacks in order to avoid IDS/IPS action, typically through the adoption of evasion that hides attacks to the monitoring system. In this paper, we test an innovative idea to build attacks, that relies on the idea of carrying out attacks against a specific component of IDS/IPS, the packet analyzers, in order to make it (at least temporarily) unavailable, hiding possible attacks against the services. In order to explore the feasibility of the approach, we focused on a particular usage example: the network traffic analysis performed during the attack/defence Capture the Flag (CTF), a cybersecurity competition where different teams attempt to find vulnerabilities in services run by the opposing team, fix them and build exploits to perform attacks. It is worth noticing that such a scenario enabled us even to work in a protected context, avoiding producing attacks that can be exploited in a production environment. Accordingly, outlining that the state of the art shows a lack of results with respect to the proposed approach we performed a security assessment of the chosen tools and demonstrated the feasibility of the approach, concluding that these attack patterns should be taken into consideration when building a protection system.

With the proliferation of the Intranet, there is a vast amount of digital information stored in the file server and shared within an organization, It is extremely difficult to monitor all access and action on a network. With numerous incidents these days, the fact that a company cannot monitor all the actions on their network can contribute to a serious problem. Packet sniffer and analyzer, also known as network protocol analyzer is a stand alone system used to monitor network. It has the capability of filtering network traffic based on Internet Protocol (IP) address, port number and protocols. It behaves as a useful tool for network administrators, network engineer and network. Hacker use packet sniffer to obtain usernames, passwords, credit card numbers, personal information and other information that could be damaging to a person or a company. When they obtain this information, hackers will use the information to do damage to other such as send a virus using the usernames and passwords captured. However, in this project the system is built for the purpose of monitoring network traffic. Sniffalyzer is targeted to be implemented in a Local Area Network (LAN) environment. Its main function is to monitor, identify and control network traffic in real time. It helps to improve network manageability and overcome network problems. Sniffalyzer can be effective as security measure for the network and shared resources. All packets passing throughout the network can be captured and analyzed and these help to secure the network.

The ability to characterize IP traffic and understand how and where it flows is critical for network availability, performance, security and troubleshooting. Monitoring IP traffic flows facilitates more accurate capacity planning and ensures that resources are used appropriately in support of organizational goals. It helps to determine where to apply Quality of Service (QoS), optimize resource usage and it plays a vital role in network security to detect Denial-of-Service (DoS) attacks, network propagated worms, and other undesirable network events. The proposed Wireless Packet Analyzer Tool (WPAT) facilitates solutions to many common Wi-Fi threats like DoS attack, Mis-associated systems from neighboring premises, Rogue APs etc., encountered by wireless networks. The attacks were simulated in an experimental set-up and WPAT is tested for required performance. A scheme that may effectively and efficiently combine detection, defense, and traceback may significantly enhance performance and mitigate false positives. The WPAT is used to identify the new IP and its route is traced by IP Traceback tool. The route contains the details such as the total number of hops, time taken for each hops in milliseconds and the IP address of the intermediate routers. The traced route is used for plotting the graph.

Wireless networks are the primary gateways for modern digital communication, yet they remain susceptible to critical vulnerabilities due to weak encryption, exposed ports, and the lack of integrated monitoring. Existing security tools are often fragmented and command-line driven, creating a significant "expert-gap" that leaves administrators unable to visualize their risk posture effectively. To address these challenges, this project introduces an Integrated Wi-Fi Network Packet-Port Vulnerability and Security Analyzer. Developed using a Python-Flask framework, the system implements a synchronized, multilayered diagnostic pipeline protected by a secure User Authentication and Login module. The backend utilizes Scapy for realtime ARP integrity monitoring and Nmap for granular service discovery. A key innovation is the Heuristic Rule-Based Audit engine, which cross-references discovered services against global CVE databases via RESTful APIs to provide live threat intelligence. To ensure proactive defense, the system features an Automated Email Alerting mechanism that triggers a critical notification to the administrator whenever the Network Health Score falls below a 50% threshold. The final implementation features a high-fidelity web dashboard that synthesizes complex telemetry into a quantifiable health score based on CVSS principles. By automating Security Audit Reports and providing structured Remediation Roadmaps, the project transforms raw network data into actionable security intelligence. This unified platform offers a proactive, scalable solution for enhancing wireless integrity in both residential and enterprise environments.

This thesis details the implementation of a command and response analyzer for a Micro-Electromechanical Systems (MEMS) Inertial Measurement Unit (IMU) sensor. The tool processes and translates the messages exchanged between a host device and the sensor into a human-readable form. Commissioned by Robert Bosch Oy for internal use, the primary goal of the analyzer is to assist engineers by automating the communication decoding and acting as an extension tool to their existing workflow. Furthermore, a key requirement was the ability to process the comma-separated values (CSV) log files exported from the Saleae protocol analyzer containing captured data from various bus interfaces. The implemented analyzer produces a chronologically structured Hypertext Markup Language (HTML) report, providing a detailed analysis of the data packets while highlighting relevant information, such as warnings and errors. Lastly, the design of the tool emphasizes future expansion. It prioritizes software component reusability, allowing for the addition of new command analysis capabilities and the processing of logs from various sources. To ensure broad accessibility, the functionalities of the Command Interface Analyzer are accessible through a web interface on both Windows and Linux devices.

In this paper, a packet analyzer for JPEG2000 codestreams is designed and its switching power and cell areas are estimated. This analyzer is intended to treat packets in the PEG2000 codestream, where the packet header and body data are separated from each other for further processing, such as encryption, partial scrambling, data hiding, and error correction. This VHDL-modeled analyzer can work at a bit rate of 50 Mb/s at minimum cost. Thus, it is suitable for real-time applications.

The rapid growth of UnderWater Acoustic Sensor Networks (UW-ASNs) has led researchers to enhance underwater MAC protocols against limitations existing in underwater environment. We propose the customized robust real-time packet inspection mechanism with addressing the problem of the search for the data packet loss and network performance quality analysis in UW-ASNs, and describe our experiences using this approach. The goal of this work is to provide a framework to assess the network real-time performance quality. We propose a customized and adaptive mechanism to detect, monitor and analyze the data packets according to the MAC protocol standards in UW-ASNs. The packet analyzing method and software we propose is easy to implement, maintain, update and enhance. We take input stream as real data packets from sniffer node in capture mode and perform fully analysis. We were interested in developing software and hardware designed tool with the same capabilities which almost all terrestrial network packet sniffers have. Experimental results confirm that the best way to achieve maximum performance requires the most adaptive algorithm. In this paper, we present and offer the proposed packet analyzer, which can be effectively used for implementing underwater MAC protocols.

This Master's project paper describes the development of XNET, a packet network analyzer which collects and displays network information in an X-Windows environment. XNET is written in the Tcl/Tk language, a language optimized for graphical user interface development. The hardware for the project consists of a radio transceiver and a Terminal Node Controller (TNC) which connects to the computer system through a serial port. XNET analyzes AX.25 wireless packet networks which predominately operate in the two meter band (144 to 148 MHz). The AX.25 data link layer protocol is a variant of the international standard X.25 protocol. The protocol has been slightly modified to meet the unique requirements of amateur radio packet communication. Unlike wire and optical fiber based networks where the network configuration is relatively stable, wireless networks continually change as nodes are switched on and off. Wireless networks are also more error prone due to the variability of the medium. It...
