What is DTLS and where do I use it?

It’s best suited for small- to medium-sized businesses with deployments that range from tens to a few hundred computers. A provisioning package (. ppkg) is a container for a collection of configuration settings.

Use the Windows Configuration Designer tool to create provisioning packages to easily configure devices running Windows client. Windows Configuration Designer is primarily used by IT departments for business and educational institutions who need to provision bring-your-own-device (BYOD) and business-supplied devices.

Windows Configuration Designer: Creating software installation package

The Windows Out of Box Experience (OOBE) is a series of screens that guide users through the basic settings of the Windows operating system when they first start a newly configured computer. The OOBE runs before the Windows shell or any other software and performs tasks required to configure and run Windows.

The OOBE process may include:

  • Initial setup
  • Language and region settings
  • Keyboard layout
  • Internet connection
  • Microsoft account setup
  • Privacy settings
  • Cortana and voice typing
  • Customizing your experience
  • Theme and colors
  • Start menu and taskbar
  • Recommended apps

The OOBE may also check for updates during the process. After completing the basic settings, Windows will start to install applications and preferred settings, and the computer will enter the Windows desktop.  Users can configure Windows to boot to OOBE by running the sysprep command by using the /oobe option. By default, OOBE starts after running Windows Setup.

Datagram Transport Layer Security (DTLS) is a communications protocol providing security to datagram-based applications by allowing them to communicate in a way designed to prevent eavesdropping, tampering, or message forgery.

Datagram Transport Layer Security (DTLS) is a communications protocol providing security to datagram-based applications by allowing them to communicate in a way designed to prevent eavesdropping, tampering, or message forgery. The DTLS protocol is based on the stream-oriented Transport Layer Security (TLS) protocol and is intended to provide similar security guarantees.

The DTLS protocol datagram preserves the semantics of the underlying transport—the application does not suffer from the delays associated with stream protocols, but because it uses UDP or SCTP, the application has to deal with packet reordering, loss of datagram and data larger than the size of a datagram network packet. Because DTLS uses UDP or SCTP rather than TCP, it avoids the “TCP meltdown problem”, when being used to create a VPN tunnel.

DTLS Paper :: What is DTLS and how is it used?

A datagram is a basic transfer unit associated with a packet-switched network. Datagrams are typically structured in header and payload sections. Datagrams provide a connection less communication service across a packet-switched network. The delivery, arrival time, and order of arrival of datagrams need not be guaranteed by the network.

Datagram-based applications are applications that use datagram networks to transport data efficiently. Datagrams are basic transfer units that are associated with packet-switched networks and provide connection less communication. They are typically structured into header and payload sections, and the network doesn’t need to guarantee the delivery, arrival time, or order of arrival of datagrams.

Datagram-based applications are often delay sensitive and rely on unreliable datagram transport. Some examples of datagram-based applications include: Real-time video conferencing, Internet telephony, Online games, and Voice-over IP (VoIP) communication.

Consider, for example, situations in which data may be lost because new data immediately follows and replaces old data, such as in video streaming or gaming. DTLS is designed in such a way that packages do not get lost or arrive in the wrong order.

DTLS is a secure protocol, as it provides privacy with datagram protocols. As a result, communication between client-server applications is possible without the communication being overheard or manipulated.

DTLS also solves the problems surrounding the loss and reordering of packets, while it does not suffer from delays that occur with streaming protocols.
