The deep-dive into how Verizon and a BGP Optimizer Knocked Large Parts of the Internet Offline Monday

A recap on what happened Monday

On Monday we wrote about a painful Internet wide route leak. We wrote that this should never have happened because Verizon should never have forwarded those routes to the rest of the Internet. That blog entry came out around 19:58 UTC, just over seven hours after the route leak finished (which will we see below was around 12:39 UTC). Today we will dive into the archived routing data and analyze it. The format of the code below is meant to use simple shell commands so that any reader can follow along and, more importantly, do their own investigations on the routing tables.

This was a very public BGP route leak event. It was both reported online via many news outlets and the event’s BGP data was reported via social media as it was happening. Andree Toonk tweeted a quick list of 2,400 ASNs that were affected.

This blog contains a large number of acronyms and those are explained at the end of Continue reading

Huawei’s 5G RAN Portfolio Wins Top Rating, GlobalData Says

Where are all the IoT experts going to come from?

If the internet of things (IoT) is going to fulfill its enormous promise, it’s going to need legions of smart, skilled, trained workers to make everything happen. And right now, it’s not entirely clear where those people are going to come from.That’s why I was interested in trading emails with Keith Flynn, senior director of product management, R&D at asset-optimization software company AspenTech, who says that when dealing with the slew of new technologies that fall under the IoT umbrella, you need people who can understand how to configure the technology and interpret the data. Flynn sees a growing need for existing educational institutions to house IoT-specific programs, as well as an opportunity for new IoT-focused private colleges, offering a well -ounded curriculumTo read this article in full, please click here

Tracking down library injections on Linux

While not nearly commonly seen on Linux systems, library (shared object files on Linux) injections are still a serious threat. On interviewing Jaime Blasco from AT&T's Alien Labs, I've become more aware of how easily some of these attacks are conducted.In this post, I'll cover one method of attack and some ways that it can be detected. I'll also provide some links that will provide more details on both attack methods and detection tools. First, a little background. [ Two-Minute Linux Tips: Learn how to master a host of Linux commands in these 2-minute video tutorials ] Shared library vulnerability Both DLL and .so files are shared library files that allow code (and sometimes data) to be shared by various processes. Commonly used code might be put into one of these files so that it can be reused rather than rewritten many times over for each process that requires it. This also facilitates management of commonly used code.To read this article in full, please click here

MPLS is dead, Long live MPLS

The initial hype of SD-WAN claimed that MPLS was dead as SD-WAN was going to remove all need for SLA based circuits. Now that we’re several years in and have some experience under our collective belts, we take a look at whether or not the original hype was correct and what real world customers are doing when it comes to selecting circuits for their SD-WAN networks.
