The Internet Security Research Group (ISRG) 's new Prossimo project seeks to make many basic internet programs and protocols memory-safe by rewriting them in Rust . . You know the non-profit Internet Security Research Group (ISRG) for its Let's Encrypt certificate authority, the most popular way of securing websites with TLS certificates. The group wants to do more. Its newest project, Prossimo , seeks to make many basic internet programs and protocols memory-safe by rewriting them in Rust . Rust, like some other memory-safe programming languages such as Go and Java, prevents programmers from introducing some kinds of memory bugs. All too often memory safety bugs go hand-in-hand with security issues. Unfortunately, much of the internet's fundamental software is written in C, which is anything but memory safe. . Explore the efforts of ISRG's Prossimo in advancing online security by reengineering protocols using Rust, aimed at eliminating memory-related vulnerabilities.. memory safe programming, ISRG Prossimo, Rust framework, internet security improvements, secure coding practices. .

The purpose of this introductory article is to take a basic look at the journey of a packet across the Internet, from packet creation to switches, routers, NAT, and the packet's traverse across the Internet. This topic is recommended for those who are new to the networking and security field and may not have a basic understanding of the underlying process. Previous articles by this author have looked at the importance of two key areas of computer security for new users: programming and networking. While they are different disciplines, both networking and programming should largely be viewed as complimentary. If it were it not for the early programming of networking protocols there would be no network. That said, does one have to be a programmer in order to fully grasp networking concepts and theory at a low level? In many cases, you do not. However, a reader's natural curiosity will likely lead him toward programming at some point, in order to further experiment with various protocols and networking theory. .

If you are reading this article, you should have a good understanding of how computers work and a working knowledge of how to use Internet tools such as web browsers, Telnet, and e-mail. In addition, you're probably already aware of the need to protect computers on your network from exterior threats, while still allowing your web and e-mail traffic to traverse your connection to the Internet. You may install a firewall to secure your network, but to configure it correctly you must know just how your computer connects to other computers and downloads web pages, exchanges e-mail, or establishes a Telnet session. You'll also need to know how to set firewall rules to differentiate the legitimate network traffic of your network users from the illicit access of hackers and other external threats. As TCP/IP is the mechanism by which your computer communicates with the rest of the Internet, you will need to have more than a passing familiarity with it. This article will give you a better idea of what is going on behind the scenes. But why do you care how TCP/IP works if you aren't a computer programmer or network engineer? You should care, because the hackers attempting to get past your network security often are computer programmers or network engineers (self-taught or otherwise), and in order to stop them you need to understand and correct the weaknesses in TCP/IP or higher-level protocols that they will attempt to exploit. In other words, know what your enemy knows. The link for this article located at Hacking Linux Exposed is no longer available. .
