Internet of Things is one of the fastest growing fields in the tech industry. New devices are constantly being invented and introduced into the market. According to Statista, there are expected to be “30.73 billion connected IoT devices in the world by 2020.” With so many new devices being introduced, it is inevitable that some of these devices will be released with vulnerabilities somewhere in the course of their product lifecycle. Many of these devices pose a risk to users and the networks to which they are connected. As many of Viasat’s customers will be adopting these IoT devices, Viasat had two intern teams working together on different aspects of IoT security. My intern team identifies devices in order to associate and offer better protection visibility to our customers. Our partner team is focused on detecting anomalies in network traffic behavior from these devices. This article summarizes both our teams’ efforts and results. (more)
I am a Software Engineering Intern working in Viasat’s Seattle office. My team’s internship project, VonBraun, is a next-generation orchestration platform for 12-factor apps at Viasat, to meet the need for a simple platform to run general-purpose (e.g. web) apps with little operational overload. It is basically a Heroku-style platform for internal use at Viasat. We aim to dramatically increase the speed at which certain kinds of apps can be developed and deployed, such as:
- Web management dashboards for various systems
- Databus loopbacks/aggregators
- Web apps that fall into the 12-factor app idealism
This summer, I have been part of Viasat’s Security Engineering Intern Project (SEIP) team at the Austin, TX office. We have successfully developed a security pipeline for detecting vulnerabilities in code repositories and websites, and retrieving initial reconnaissance scans of targeted internal IP space. I worked on developing the front end of the web application, used offensive security tools to find open vulnerabilities, and also worked on a passion project – “Security Chatbot” to unleash the full potential of ChatOps using Amazon Web Services.
I am an intern in the Global Infrastructure group in the Austin, TX office this summer. Our group is responsible for cloud and infrastructure engineering projects that allow Viasat’s development teams to move fast and deploy software efficiently. Containers and container technologies are largely responsible for that and they have exploded in popularity the last few years.
Containers are a form of packaging in which applications can be abstracted from the environment in which they run. But when you start to run a large number of containers in production you have to deal with the underlying complexity of having to maintain individual machines, deal with uptime, and move resources around. That is where Kubernetes comes in.
Like most developers, we think what we are developing is the most important part of our system. Our infrastructure service is the center of the universe; everything else revolves around it. Ok in reality, Viasat’s brand-new satellite broadband service is the main thing, the virtual network is built to support it. But the virtual network is very essential to the whole customer experience and a pathway for Viasat to create a planet-wide broadband network.
In the last few years, we’ve witnessed explosive growth in the role machine learning (ML) plays in technology. Making good predictions from data has always been important in our industry, but modern machine learning techniques allow us to be much more systematic. However, this wealth of new ML algorithms and services present new challenges for software developers. (more)
Viasat is leading a new wave of communications satellite innovation. This is a by-product of our belief that there is always a better way and not being satisfied with the “state-of-the-art” industry capabilities. It demands we think differently as we develop next generation technologies to enable satellite systems that are demonstratively better than have been offered in the past. Our unique industry position allows us to optimize the entire system, from the ground network to space payloads to user equipment. For high-throughput satellite payloads like ViaSat-1, ViaSat-2 and ViaSat-3, new technologies will need to be developed that get the industry beyond the status-quo and allow for orders of magnitude improvement in capacity and coverage area. We’ll discuss how new solid-state integrated circuit technologies are a tool that can be used to improve critical dimensions of performance for new satellite payloads. (more)
Our next generation network is basically built with mostly virtual network functions. These are services that ViaSat has migrated from custom/purpose built hardware to a virtual platform. One key component for construction of virtual networks is orchestration. It ties the deployment of the virtual network functions with the rest of the network using the network controller service that I wrote about in my last blog.
We would like to show you Azimuth, a new tool for exploring networks, built by interns at light speed. It’s like a command-line, except instead of the output being text, you get an interactive 3D graph. (more)
