Most technology systems today are distributed systems, made up of app servers, databases, and caches. Managing distributed systems is tricky, and writing distributed systems is even trickier. Our mission is to make building and running these systems as easy as building or running an app on your smartphone.

How safe is 5G really?

Article | February 19, 2020

The 5G era is about to arrive, to enable a host of new business applications. The next-generation cellular technology is designed , but 5G security is also much more complicated to manage. 5G poses an elevated security threat partly because there are more vectors through which adversaries can attack. The technology is set to enable a huge number of connected devices, collectively known as the ).

Did 5G cause coronavirus? Four reasons why ‘dangerous’ conspiracy theory is completely wrong

Article | April 14, 2020

5G is a little higher at 3.4GHz to 3.6GHz, but that's tiny when you consider that microwaves go up to 300GHz. And visible light comes in at a range of around 430THz to 770THz. That's more than a thousand times higher than the maximum microwave – and 100,000 higher than 5G. Dangerous radiation, like UV rays, X-rays and gamma rays are also far higher up the spectrum still. Early theories suggested 5G could lead to cancer – and now crackpots have linked it to coronavirus too. But it's simply impossible for 5G to cause any of these problems. Radiation damages cells by breaking them apart, but 5G microwaves simply lack the power to do this. 5G is a low-frequency radiation, far below infrared and visible light. In fact, it's essential that 5G is low-frequency, because higher frequencies are less useful at delivering mobile signals over large areas. We know that this level of radiation is safe, because otherwise the visible light from our televisions would have killed us a long time ago.

Trump's 'Secure 5G & Beyond Act' Explained: What It Actually Means

Article | March 29, 2020

The Trump White House has signed the "Secure 5G and Beyond Act of 2020," paving the way for the creation of a plan to secure 5G networks and protect related innovations. With 5G devices rolling out in the US market, and providers expanding their 5G coverage, the future of mobile tech is getting closer, and the U.S. government is beginning to look more seriously at how it can best be protected. The path to 5G-enabled devices and compatible services in the United States began opening up in 2019, with major mobile companies introducing a handful of 5G-enabled phones and limited service options. With more devices built to capitalize on 5G on the horizon - and demand for 5G access from other industries on the rise - the signing of the Act gives US lawmakers a path toward legislation to help protect US businesses, citizens, and strategic allies.

How 4G and 5G networks are vulnerable to Denial-of-Service attacks

Article | March 26, 2020

Mobile operators are racing to upgrade their networks with 5G connectivity while at the same time expanding 4G LTE coverage throughout the world. Though the latest generations of cellular technology offer faster performance and other benefits over their predecessors, they're vulnerable to some of the same security flaws. A report released Thursday by Positive Technologies explains how and why existing 4G and new 5G networks can be hurt by Denial-of-Service (DOS) attacks in particular. For its report "Security Assessment of Diameter Networks 2020," Positive Technologies simulated external attacks against 28 telecom operators in Europe, Asia, Africa, and South America during 2018 and 2019. Specifically, the company looked at 4G and 5G networks using Diameter signaling protocol, a method for coordinating data among different Internet Protocol (IP) network elements.
