Wireshark is a free and open-source network protocol analyzer. It is used for network troubleshooting, analysis, software and communications protocol development [1], and education. Wireshark captures packets from a network connection and displays them in a human-readable format [2]. It is capable of capturing data from a wide range of protocols and analyzing the data to identify problems and find potential security issues. Additionally, Wireshark can be used to examine the structure of different network protocols and can be used to debug network protocol implementations. [Hidden Content]

Description Welcome guys in this course I will be your instructor. In this course I will talk straight to the point. Therefore, we will cover more in less time. I tried my best to make this course compact and valuable. Because lots of people don’t have enough time to watch lengthy courses. So, if you are one of those then this is perfect course for you. Wireshark is a network protocol analyzer, or an application that captures packets from a network connection, such as from your computer to your home office or the internet. Packet is the name given to a discrete unit of data in a typical Ethernet network. Wireshark is the most often-used packet sniffer in the world. Wireshark is a software tool used to monitor the network traffic through a network interface. It is the most widely used network monitoring tool today. First, Did you know that being able to understand what’s on the network is considered a superpower? It’s true. Packet analysis helps you to understand the traffic on your network so you can identify latency issues and actively monitor the network for attacks. In this course, I’ll provide an overview and benefits of traffic capture. I’ll cover how to download and install on a PC. Then we’ll explore the Wireshark interface. I’ll cover how to tap into the data stream and use display and capture filters. I’ll review the OSI model and encapsulation. Then we’ll do a deep packet analysis of common protocols, such as TCP, IP and DNS. I’ll finish with working with the expert system and how to troubleshoot network latency issues. Wireshark is the world’s foremost and widely-used network protocol analyzer. It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions. Wireshark captures packets so whether you’re on incognito mode or not, it doesn’t matter — the network traffic will be captured. When you’re finished with this course, you’ll be able to immediately put Wireshark to use in your own work. I invite you to join me on this Wireshark journey. Let’s get started. Thank you. Who this course is for: Who wants to learn Wireshark Who wants to learn about packet analysis Who wants to learn, understand, and identify the traffic on their network Network Teams, Network Engineers, Cybersecurity Teams and Professionals Ethical hackers, Network students Anyone who is interested in the field of Networking Requirements Internet Connection [Hidden Content] [hide][Hidden Content]]

Description This course will teach you how the primary encryption protocol used on the internet, TLS, operates. You’ll learn about the process and all the protocols involved in encryption using TLS. TLS, sometimes called SSL, is the primary method of encryption for most communication on the internet including web and email communication. In this course, Analyzing and Decrypting TLS with Wireshark, you’ll learn the process and protocols TLS uses to encrypt traffic. First, you’ll see a visual description of how TLS encryption operates, explaining all of the critical steps of encryption and protocols involved. Next, you’ll observe a packet capture of an HTTPs website using Wireshark, and examine the unencrypted components of the TLS handshake. Finally, you’ll learn how to capture session keys on your local computer in order to decrypt TLS traffic in Wireshark, and then examine the entire TLS handshake process. By the end of this course, you’ll be able to capture HTTPs traffic with Wireshark, capture the session keys for the TLS encryption, and decrypt the HTTPs session in Wireshark.

Description Ethical hacking is a process of detecting vulnerabilities in an application, system, or organization’s infrastructure that an attacker can use to exploit an individual or organization. They use this process to prevent cyber attacks and security breaches by lawfully hacking into the systems and looking for weak points. Confidentiality, integrity and availability, also known as the CIA triad, is a model designed to guide policies for information security within an organization. The model is also sometimes referred to as the AIC triad (availability, integrity and confidentiality) to avoid confusion with the Central Intelligence Agency. Network security is the protection of the underlying networking infrastructure from unauthorized access, misuse, or theft. It involves creating a secure infrastructure for devices, applications, users, and applications to work in a secure manner. What is Nmap ? Nmap is a free and open-source network scanner created by Gordon Lyon. Nmap is used to discover hosts and services on a computer network by sending packets and analyzing the responses. Nmap provides a number of features for probing computer networks, including host discovery and service and operating system detection. Some of this tool’s best features are that it’s open-source, free, multi-platform and receives constant updates each year. It also has a big plus: it’s one of the most complete host and network and port scanners available. It includes a large set of options to enhance your scanning and mapping tasks, and brings with it an incredible community and comprehensive documentation to help you understand this tool from the very start. Nmap can be used to Create a complete computer network map. Find remote IP addresses of any hosts. Get the OS system and software details. Detect open ports on local and remote systems. Audit server security standards. Find vulnerabilities on remote and local hosts. It was mentioned in the Top 20 OSINT Tools article we published, and today we’ll explore a little bit more about this essential security tool with some practical terminal-based Nmap commands. What is Wireshark ? Wireshark is a free and open-source packet analyzer. It is used for network troubleshooting, analysis, software and communications protocol development, and education.
