FTP is one of the oldest network protocols still in use. In its first iteration, it was created in 1971 as a way to quickly move files between computers and has been in continuous use ever since. It’s particularly common on the web, where it is responsible for moving files and data.

Unfortunately, while common, it is also insecure. FTP transmits user credentials, file contents, and other data in the clear. For that reason, anyone with a packet sniffer and a bit of patience is free to take a look at it. This video looks at the security of FTP traffic and why it is problematic. It covers:

  • How to set up an FTP server on Windows Server 2008 and configure a simple site
  • The use of a packet sniffer (Wireshark) on Ubuntu to monitor network traffic

Server Security, Part 2 Title SlideGood network security begins with good server security. Unfortunately, though, server security is a multifaceted problem.

There are the straightforward issues, such as how to make sure that the physical machine is safe. But there are also the software challenges, and that is where things can become complicated, difficult, and ugly.

The plan for securing two different servers might vary widely, depending on what the servers will be used for and how they will be accessed. This can make planning the security a nightmare. Luckily, Windows Server offers one very powerful feature that can make planning and configuring the security options a little bit easier: Security Templates.

This video will introduce security templates on Windows Server 2008. It will show how to create them, how they can be used to audit the security settings for a server, and how to change settings that might not be in compliance.

As difficult as it can be to secure individual computers, making sure that a network is secure is even more challenging. This is because, instead of working with a single machine, you have an entire network of devices to worry about. It’s a classic case of, “if the security of one is threatened, we’re all threatened.”

Luckily, there are several tools that can be used to “harden” individual computers, thereby making the network as a whole more secure. This series of videos will explore a few of those, including the Windows Server Security Configuration Wizard, the Role of Security Templates, and some of the Linux/Unix Security best practices.

This first video kicks things off by looking at the Windows Server 2008 Security Configuration Wizard and shows how to configure a simple firewall setting.

Windows Server Core is a relatively new version of Windows Server. Like it’s slightly more mature sibling, the “full” version, it is tremendously powerful. Server Core allows you to set up Active Directory domains, DNS/DHCP, and web servers. It can help secure your infrastructure, and probably floss your teeth.

But that isn’t what makes it interesting. Server Core is interesting for what it doesn’t have: the Windows Server GUI. Like in the case of Linux servers, nearly all of the action happens in the command line. This makes Server Core light weight and an excellent candidate for network virtualization, as it can run all of the core networking services need to administer a domain.

In this video, we take a look at how a Server Core installation can be configured to run as a DHCP server. It will walk you through the process of installing the DHCP server role from the command line, registering the DHCP service with Active Directory, and configuring the first zone. When combined with the earlier Active Directory tutorial, this video describes a way to run the three core networking services needed for domain administration – DNS,  DHCP, and Active Directory – on a single server.

This lays the groundwork for later networking and security tutorials by allowing us use the less resource intensive Server Core for simulation and exploration rather than the full Windows Server virtual machine.

In the world of large networks, Microsoft’s Active Directory holds a near monopoly. There are many reasons for this, but I’ll only cite one: it’s an excellent product. It offers much more than just mere authentication for users. It also represents desktop computers systems as objects, and makes it easy to manage and secure them. It provides application deployment, standardizes system configurations, and locks down user interfaces through Group Policy Objects. Finally, it issues Kerberos tickets to enable single sign-on for enterprise applications.

Using Active Directory to manage a domain of computers is smart. If you have non-Windows clients (such as Windows or Mac computers) on the network, though, it can seem like a daunting prospect to add them to an Active Directory Domain. In this series of videos, I will walk you through the process of adding a Linux client to an Active Directory Domain.

It covers:

  • Where to download the software
  • How to configure the DNS settings and network settings of the Linux system so that it is able to localize Active Directory domains
  • How to join the domain
  • Some hints on where to start troubleshooting if things go wrong

Windows Server 2008 is Microsoft’s latest server operating system and comes with a number of features – the inclusion of virtualization technology, the ability to create private clouds, and streamlined administration – that make it an extremely attractive options for business or groups that need a server. And because it is often bundled with technologies such as Active Directory, it is very common to find Windows Server machines on nearly every network.

In this tutorial, I’ll walk you through how to install Windows Server 2008 on a VMware virtual machine. It shows how to install both the full version of Windows Server and Server-Core. The video also demonstrates how to configure virtual machines to participate in an external network (such as the Internet) and an Internal (host-only) network. Configuring a virtual machine in this way allows you to simulate network behavior, test software, or demonstrate security concepts.

Active Directory is one of the most pervasive technologies in the Windows networking world, with good reason. Active Directory makes it easy to manage users, security policies, and network resources. It’s so good, many companies rely on it exclusively to manage their network infrastructure.

This video introduces Active Directory and shows how to install/configure it on a server running Windows Server 2008. It then shows how to add additional servers to the domain, in this case a Server-Core machine, and configure the second machine so that it is a backup domain controller. Finally, it briefly covers how to create user accounts and configure sharing of resources (like shared folder volumes) for users of the network.

Note: This video was created as part of a networking class that I am currently teaching. I’ve posted it here in the hope that it will be useful to a slightly wider audience.

Though the Internet, and the many things that it enables, may seem magical, the system is built upon tried and true pillars. In this video, I take a look at how two of those pillars, DNS and DHCP work by deploying them on a virtual network using VMware.

The tutorial includes a brief introduction to virtual networks, how to configure the virtual network adapters, and the installation of DNS and DHCP services on Windows servers.

The ability to create custom installation images (whether they be of servers, desktops, or more specialized devices) is a tremendously handy thing. In Windows Server 2008, Microsoft released a tool that makes the creation of these images much easier called ImageX.

ImageX works hand-in-hand with a second tool, called the Windows Preinstallation Environment (WinPE). In this series of videos, I will explain how you can use ImageX and Windows PE to create custom images and deploy them.

In this video, Part 2 of the series, we will cover how to create a custom WinPE image that includes ImageX and other useful tools. Part 1 talks about where to find and download WinPE/ImageX and how to install them.

The entire series is from a networking infrastructure course that I am currently teaching. I am posting it here in the hope that it will be helpful to a wider audience.

The ability to create custom installation images and deploy them to other machines is a very handy skill. If you are working in a large environment, you can create a master image with all of the tools needed for your work that could be used on all of your hardware. In this series of videos, I will explain how you can use ImageX and Windows PE to create custom images and deploy them.

Note: The following video is part 1 of a series that I have put together for a networking class that I am currently teaching. I have posted it here in the hope that it will be helpful to a slightly wider audience.
