Don't worry, guests will be back to chat with us in the fall. But until then, join us on #CyberChats as we stay cool in the summer heat and dive into the freshest topics in cyber. In today's episode, we dip our toes into an introduction to cryptograhy. What is cryptography? Why do we need cryptography? How does cryptography work? To answer these questions, we'll talk about how computers think -- while you and I might look at a picture and see colors, a computer can't think in colors. So, how do computers understand reds, blues, and greens in images? Tune in to find out. After the episode, put your new knowledge to practice in our first of three Summer Cyber Challenges on MetaCTF: HexCryption!

In this throwback episode from Season 1, we hear from two incredible women in cyber to help us explore our risk appetite.Not all people or businesses can tolerate the same amount or type of risk… so that means everyone approaches manages risk differently. What are you risking when you decide to take a certain class or download a particular application? Are you missing out on friends? Are you sacrificing speed on your device? What does that type of analysis look like in the cyber career space? Ultimately, risk management is about making smart decisions for our own contexts. In this episode, we talk with Erica Wilson, VP of Global Cybersecurity and Privacy Risk Management at Reinsurance Group of America, and Jamie Kemp, President of Women in Cybersecurity(WiCyS) at Lakota West High School. We chat about the unique perspectives of our guests and how they got into cyber, as well as issues specific to girls and women in cybersecurity and resources to support them. By listening to our podcast and sharing it with your network, you’ll be helping us to raise awareness and accessibility of cybersecurity careers. Together, we can create a more diverse and resilient cybersecurity workforce that can tackle the challenges of the future. So, what are you waiting for? Tune in and join the conversation today!

We don't play around in cybersecurity, but we definitely game! In this episode, our guests detail the role that games and game strategy play in teaching us how to think like an adversary and keep safe online. We chat with DJ Strickland about his work and advocacy in bringing more representation into the cyber community through video games and comic books. But, like DJ experienced, we learn that hackers use adversarial thinking to exploit vulnerabilities in computer systems. So, our host challenges guest Dr. Seth Hamman to a tense game of rock-paper-scissors to show how game theory can help us understand the motivations of cybercriminals and anticipate their actions to protect ourselves against them. Whether you're a seasoned pro or just starting to learn about online safety, you won’t want to miss this episode to level up your cybersecurity skills and stay safe online! After you listen, you can put your own game theory skills to the test by completing this week’s episode challenge!
