By using the same backend for Threads, we could leverage a lot of the existing tech stack for Threads and reuse most of our existing data models, business logic, security features, and server infrastructure. That’s because email is interoperable and these two companies both conform to the SMTP protocol for delivering emails.

When you want to send the JWT to a server, you put the header, payload, and signature inside the box. Then you send it over to the server. The server can easily read the header and payload to understand who you are and what you want to do. With each iteration, the protocol has evolved in new and interesting ways.

A TCP port is a unique number assigned to specific services and applications that run on a server. It serves as an endpoint for communication between a client and the server, allowing different communication processes over a network. TCP ports operate at the transport layer of the Internet Protocol Suite. What is a TCP Port?

At the beginning of the month, Microsoft released an advisory and security patch for a serious Windows Server Message Block (SMB) vulnerability called the Windows SMBv3 Client/Server Remote Code Execution Vulnerability (AKA Windows SMBv3 RCE or CVE-2020-0796). This would solve the problem for SMB servers but not SMB clients.

VPNs encapsulate data and encrypt the data using an algorithm contained within the transmission protocol. Todays VPNs primarily use one of the three major protocols, each of which has its advantages and disadvantages: PPTP is one of the oldest protocols and came into existence back in the days of Windows 95.
