Networking Concepts and Protocols

by Ross Bagurdes

Apr 20, 2018 / 5h 26m

Beginner • 5h 26m

Start Course
Description

Listening to a data network engineer speak about the equipment, maintenance, and operation of a networked system can often feel like you are listening to a foreign language. Although data networking hardware is not remarkably different in operation to your desktop computer, it’s application and configuration requires the implementation of protocols to ensure data moves from one device to another device, quickly and without error. In this course, Networking Concepts and Protocols, you will learn how the most important protocols on the Internet, like IP, TCP, and HTTP work together to deliver a web page from a server on the Internet to your desktop’s web browser. First, you will learn the secrets of the IP address. Next, you will learn the most important rules to help you understand if two devices can communicate or not. Finally, you will learn to use the OSI model to organize protocols to better understand how they interact with each other. By the end of this course, you will be able to quickly examine network configuration on your workstation and clearly understand the different components.

Introduction to Enterprise Network Infrastructure

by Ross Bagurdes

Apr 20, 2018 / 2h 58m

Beginner • 2h 58m

Start Course
Description

Different sized networks require different types and sizes of networking hardware. Your home network has only a few connected devices, and usually only one or two physical network devices. In this course, Introduction to Enterprise Network Infrastructure, we will use the concepts of a home network as a starting point to describe how big businesses deliver data network connections to thousands of devices. First, you will learn about the variety of network hardware options you have at your disposal to meet your specific needs. Next, you will learn about the different cabling types and how fiber optics are categorized for data network use. Finally, you will learn about the different types of 802.11 wireless networks and where they are used. By the end of this course, you will be able to identify the most important networking hardware and explain its purpose in the data network.

Network Management and Operations

by Ross Bagurdes

Apr 20, 2018 / 2h 30m

Beginner • 2h 30m

Start Course
Description

Understanding the vocabulary, protocol operation, and hardware configuration is surprisingly only a small component of maintaining an enterprise data network. In this course, Network Management and Operations, you will learn how data moves through systems and how to reliably and securely keep the network moving data. First, you will learn about different types of network documentation. Next, you will learn about the mechanisms that keep systems working, even when a device fails. Finally, you will explore the tools used to monitor the state of network devices. By the end of this course, you will understand the secure mechanism engineers use to access network hardware, as well as, understand the difference between a hot, cold, and warm data center site.

Network Security Fundamentals

by Ross Bagurdes

Apr 20, 2018 / 2h 16m

Beginner • 2h 16m

Start Course
Description

Data breaches have become common place in national and world news, and because of this, engineers now find themselves in new roles in organizations, exclusively focused on securing information. In this course, Network Security Fundamentals, you will learn about the different types of attacks used to bring down networks, and/or steal data from them. First, you will examine the physical security of data centers, password creation recommendations, user account privileges, and devices to monitor network behavior. Next, you will learn about techniques for mitigating these attacks. Finally, you will learn about mechanisms for encrypting wireless traffic. By the end of this course, you will know the difference between WEP, WPA, WPA2, and how you can use multifactor authentication to prevent unauthorized account access.

Network Troubleshooting and Tools

by Ross Bagurdes

Apr 20, 2018 / 2h 54m

Beginner • 2h 54m

Start Course
Description

There are what feels like a near infinite number of moving parts in a data network, which means that when things go wrong, they often have cascading consequences that can prevent users from accessing the resources required to do their jobs. In this course, Network Troubleshooting and Tools, you will learn techniques and tools for troubleshooting broken network components. First, you will learn how to use command line utilities like ipconfig, ping, nslookup, Nmap, and netstat. Next, you will learn how to use Wireshark to capture and examine an unencrypted website. Finally, you will learn to use iperf to measure the bandwidth of an internal network and use Nmap to run a port scan on a remote server. By the end of this course, you will know-how to troubleshoot and track down network problems, which are critical skills you must have as an engineer.
