How to Build a Computer from Scratch

5/29/2019
More
In today’s market, chipmakers design and fabricate chips using supply chains, labor forces, locations, and processes that they don’t always monitor or control as closely as customers with high-security requirements need them to. Without proper security or visibility into how companies fabricate chips, a malicious actor could insert something into the hardware that would provide a way for attackers to target and exploit high-profile organizations that use it. In this SEI Cyber Talk episode,...

What’s Going on with Near-Term Quantum Computing

5/15/2019
More
In this SEI Cyber Talk episode, Ritwik Gupta, Daniel Justice, and Jason Larkin explain what quantum computing is and how it works, and they discuss the benefits that quantum computing can offer, such as increasing the speed at which computers can solve certain algorithms. In the near term, however, quantum computing is limited because quantum computers still present high error rates. Ritwik, Daniel, and Jason explain how these computers must dedicate some of their architecture to error...

How to Fit the Internet into a Box

5/1/2019
More
For the sake of security and safety, exercise environments where cyber operators train often need to be disconnected from real networks. To make these environments more realistic, the Software Engineering Institute (SEI) developed software that simulates the public Internet to give trainees the sense that they are in a real environment. In this SEI Cyber Talk episode, Rotem Guttman and Gabe Somlo explain how this software works to replicate common websites that users see on the Internet and...

Defending Your Computer Network from DNS Hijacking

4/16/2019
More
Recently, the Department of Homeland Security (DHS) released a warning about DNS hijacking and how website owners can protect themselves against it. To explain what DNS hijacking is and how adversaries use it to steal sensitive information, Elli Kanal and Daniel Ruef give a high-level overview of how DNS and network traffic work. They discuss how servers communicate with each other, what kind of information servers send to each other and why, and how adversaries can hijack that information....

What’s It Like to Intern at the SEI?

4/8/2019
More
In this SEI Cyber Talk, Emerging Technology Center interns Dominick Gurnari and Sandra Sajeev discuss what it’s like to intern at the SEI, a DoD federally funded research and development center. We discuss what’s cool about working in a research lab, what’s not, and how the internship differs from traditional industry internships.

Learning by Observing via Inverse Reinforcement Learning

3/22/2019
More
This SEI Cyber Talk episode explains how inverse reinforcement learning can be effective for teaching agents to perform complex tasks with many states and actions. Inverse reinforcement learning (IRL) is a formalization of imitation learning, which involves learning a task by observing how it is done. The difference between IRL and simple imitation learning is that, in addition to taking note of the actions and decisions needed to perform a task, IRL also associates those actions with the...

What is Cyber Hygiene?

3/6/2019
More
This SEI Cyber Talk episode introduces the concept of cyber hygiene, which bears an analogy to the concept of hygiene in the medical profession. Like the practice of washing hands to prevent infections, cyber hygiene addresses simple sets of actions that users can take to help reduce cybersecurity risks. The participants in this Cyber Talk episode discuss what some of those practices are, such as implementing password security protocols, and how organizations can determine which practices to...
