Networking & Cybersecurity Concepts

  Introduction GNS3 (Graphical Network Simulator) is a software tool that simulates complex networks. It allows the combination of virtual and real devices. It is used by many large companies like Walmart, AT and T and NASA. You can also use GNS3 on any computer to experiment with various router configurations. It is helpful for network and Network Security certificates such as CCNA, CCNP, CCIE and so on. This allowed users to build, design and test networks without needing physical hardware. History It was first released in 2008, developed by Jeremy Grossman. His motivation on developing this was to provide graphical user interface for Dynamips, a cisco IOS emulator. Additionally, it was created to make network simulation more accessible and practical for learning and professional development. People who liked the program have supported making it even better and updating it with more features. Features and Benefits This allows users to create virtual labs and practice CCNA/C...

 Introduction    An effective software program for examining network traffic is called Wireshark. It is a crucial tool for network troubleshooting, security research, and understanding how networks work since it enables users to record and examine data as it moves over a network. Students, IT workers, and cybersecurity specialists utilize it extensively for understanding data flow between devices.    History  Gerald Combs first created Wireshark in 1998 under the alias "Ethereal." Due to trademark concerns, it eventually changed its name to Wireshark in 2006. It has developed into a well-regarded network monitoring tool over time, and its features are constantly being enhanced by a vibrant community.   Features and Benefits  Users can record and thoroughly examine real-time network data with Wireshark. It is adaptable for various kinds of network analysis because it supports a wide range of network protocols, including HTTP, TCP, UDP...
