If you’re thinking about getting into tech or are already in it and considering your next step, network security training is one of the smartest moves you can make—and we have five powerful reasons to back that up. But before we dive in, you might be wondering, What’s the difference between ‘network security’ and cybersecurity?  (Don’t worry. We hear this question all the time.) Let’s define what “network security” refers to, specifically: “Network security” is a subset of cybersecurity that protects company assets from breaches and attacks. At Cisco, we define network security as protecting the underlying networking infrastructure from unauthorized…

Just as Cisco helped build infrastructure for the internet, we’re now creating quantum networking technology that will be the foundation for the quantum internet, making quantum computing practical years ahead of current timelines. Our approach could accelerate impactful quantum computing and networking applications from decades away to just 5-10 years. Today, we are announcing two milestones: Unveiling of Cisco’s Quantum Network Entanglement Chip – a research prototype and breakthrough technology that enables quantum networks to scale and connect quantum processors for practical applications Opening of Cisco Quantum Labs – our dedicated research lab in Santa Monica, CA, where quantum scientists…

IP is the engine behind everything—our favorite streaming services, the global array of IoT sensors connecting people and things, and the workload we access in the cloud. It is the heart of our digital world, connecting us like an invisible and persistent presence in everyday life. Foreseeing IP market demands Over the decades, the industry has introduced additional complexity with numerous layers and extensions to the IP protocol, each designed for a specific use case: MPLS in the core, UDP/VXLAN in data centers, GTP in the mobile industry, and NSH for service chaining. While these bespoke solutions may work for…

Summertime around here is hot, and sometimes we need a cool summer treat. Like a chocolate chip cookie served with a cup of coffee in cool popsicle form, this is one summer treat I make for me! With a creamy, coffee flavor, and crunchy chocolate chips, it’s the perfect summer dessert. Dairy-Free Chocolate Chip Coffee Popsicles This recipe makes four popsicles, so you don’t need a really large quantity of any ingredients. It’s perfect for when you have a little brewed coffee left to use or a partial can of coconut cream. Although coffee lovers can certainly double the recipe!…

Originally published in the Well Being Journal, March/April 2025 edition, my open letter addresses the American Dental Association (ADA) with an urgent appeal to reform two long-standing practices in U.S. dentistry: water fluoridation and the continued use of mercury amalgam fillings. With mounting evidence linking both to systemic health concerns, I’m calling on the ADA to align its policies with modern science and global best practices for public health. A Call for Progressive, Evidence-Based Practices in Dentistry The field of dentistry has long been at the forefront of preventive care, with advancements that have improved the quality of life for…

Stewart Whitson, a senior director at the Foundation for Government Accountability, testified before Rep. Marjorie Taylor Greene’s DOGE subcommittee in Washington, D.C., on Feb. 12. The hearing was titled “The War on Waste.” Al Drago/Getty Images hide caption toggle caption Al Drago/Getty Images PHOENIX — As an Arizona bill to block people from using government aid to buy soda headed to the governor’s desk in April, the nation’s top health official joined Arizona lawmakers in the state Capitol to celebrate its passage.

Did you know that a pill you likely already have in your medicine cabinet could help stop cancer from spreading? That’s right — aspirin, the little white tablet you pop for headaches or to keep your heart healthy, does more than you think. Scientists are discovering that aspirin could help your body fight cancer, especially when it tries to move to new places in your body. This movement is called metastasis, and it’s what makes cancer so dangerous. In fact, metastasis is responsible for nine out of 10 cancer deaths.1 Finding a way to stop it could save lives —…

At RSA Conference 2025, one theme echoed across the show floor: security teams don’t need more alerts—they need more certainty. As threats move faster and operations get leaner, organizations are shifting from reactive investigation to proactive, automated forensics. That’s why we’re excited to announce a major leap forward in Cisco XDR: automated forensics built into the detection and response workflow. The Modern SOC Struggles with Confidence, Not Just Complexity It’s no longer about just identifying suspicious activity. Today’s security tools can surface anomalies such as a rogue login, a strange process, or a lateral movement attempt. The real challenge? Proving what happened—and how…

Gain-of-function research, became especially controversial and politically polarized during the COVID-19 pandemic. One theory states the SARS-CoV2 virus spilled out of a Chinese laboratory in Wuhan, China. Feature China/Future Publishing/Getty Images hide caption toggle caption Feature China/Future Publishing/Getty Images President Trump issued an executive order Monday restricting federal funding for research that involves a controversial field of scientific study known as “gain-of-function” research. The research, which is also known as “dual-use” research, involves experimenting with viruses and other pathogens that have the potential to trigger a pandemic. Those studies could discover how infectious agents might become more transmissible or make…

Co-authors: Lou Norman and Erich Stokes Applications and the Benefits of Network Telemetry Welcome to Part 3 of this blog series “Defining Network Telemetry.” In this section, we will discuss the true value of network telemetry and explore its wide-raging applications. By leveraging telemetry data, organizations can achieve significant improvements in network management and security. To recap, in Part 1, we discussed how network telemetry is a transformative tool for the US Public Sector, providing comprehensive insights into network performance, security, and usage patterns. In Part 2, we discussed how network telemetry plays a crucial role in enhancing security response times by providing…
