    #586: Stop zero days without a patch: You need to learn eBPF

    How has AI changed cybersecurity and enterprise networks? In this interview, Michael (General Manager for Cisco's Campus Networking) joins David Bombal to discuss the real-world impact of agentic AI, physical AI, and modern security threats. Discover why the U.S. cybersecurity agency (CISA) reports that the mean time to exploit vulnerabilities has plummeted from 10 months to just 10 hours due to AI systems chaining CVEs together. Learn how autonomous agents are shifting campus and branch environments from traditional north-south traffic to massive east-west flows, creating up to 9x the bandwidth demand. Michael breaks down how network segmentation and "least agency" protect data, how Cisco Live Protect utilizes eBPF inside the Linux kernel to create a compensating shield before a patch is ready, and how line-rate encryption with post-quantum cryptography protects against "harvest now, decrypt later" threats. Finally, find out why network engineering remains an incredibly critical, high-demand career path in 2026.

    #585: Run Full WiFi Networks in your laptop 🤯

    In this episode, David Bombal sits down with Joe and Dalton from Cisco to break down the biggest Cisco Modeling Labs (CML) 2.10 release yet. Joe demos the new open source MCP server (model context protocol) that lets an AI model like Claude build a full CML lab from plain English. Just by asking for three IOL routers with a simple BGP config, the AI looks up the node definitions, invents the IP addresses, builds the topology, chooses eBGP on its own, and even starts the lab and waits for convergence. From there you will see the MCP server spin up a CCNA troubleshooting scenario from the official blueprint, quiz you, review your console history and final config, and hand back an honest evaluation with coaching tips. It can even turn a BGP packet capture into a ladder diagram to explain how the protocol works. Dalton then shows off CML 2.10's new wireless fabric, which runs end to end WiFi simulations with no real radios or physical access points. Watch signal strength change as you drag a client across the canvas, simulate roaming between two APs, add link conditioning to mimic a concrete wall, and run wireless packet capture on the .11 frames. Finally, Joe walks through the upgraded breakout tool that streams live packet captures straight into Wireshark so you can troubleshoot BGP and other protocols in real time. Everything shown works in the free version of CML, making this a must watch for anyone studying for the CCNA or leveling up as a network engineer.

    #584: Will this replace PoE (Power over Ethernet)?

    Big thanks to NTT DATA for sponsoring this video and to Cisco for sponsoring my trip to Cisco Live Vegas. For more information about NTT DATA and Cisco’s partnership, click here https://services.global.ntt/en-us/abo... 1000W touch safe power sounds impossible, but Class 4 Fault Managed Power is changing how we think about power delivery for AI data centers, buildings, networking, and IT infrastructure. In this interview, we look at how Cisco, NTT, and Panduit are approaching the next generation of energy networking systems. Traditional Power over Ethernet is useful for endpoints like access points, cameras, sensors, and phones, but PoE tops out around 100 watts. Fault Managed Power introduces a new class of power delivery that can deliver much higher wattage while intelligently shutting down when it detects a fault, short circuit, or unsafe condition. The conversation explains why this matters now. AI is driving massive demand for data center compute, but that compute requires more power, more cooling, and more efficient infrastructure. The guests explain how AC-to-DC conversion losses add up across multiple power conversion stages, how transmission and distribution losses waste energy before it even reaches the building, and why many legacy data centers spend a large amount of energy on cooling and non-useful power. A key example from the discussion: an average 5 megawatt, air-cooled data center moving to direct liquid cooling and fault managed power could save 75% of its energy cost. That same energy profile could also translate into 2.3x the compute for the same amount of energy. We also discuss touch-safe DC power up to 400V, why DC-to-DC power matters for data centers, how this technology could reduce material and labor complexity, and why network engineers, electricians, data center operators, and IT professionals should understand Class 4 Fault Managed Power. This is not just about sustainability. It is about energy cost, AI infrastructure, safer power delivery, faster deployment, data center efficiency, retrofits, new builds, and the future of networking. // Stephen Kelly SOCIAL // LinkedIn: / stephen-kelly-70737a9 // Denise Lee SOCIAL // LinkedIn: / deniseleeyeh // Website REFERENCE // https://www.nttdata.com/global/en/ // David's SOCIAL // Discord: discord.com/invite/usKSyzb Twitter: www.twitter.com/davidbombal Instagram: www.instagram.com/davidbombal LinkedIn: www.linkedin.com/in/davidbombal Facebook: www.facebook.com/davidbombal.co TikTok: tiktok.com/@davidbombal YouTube: / @davidbombal Spotify: open.spotify.com/show/3f6k6gE...

    #581: AES Explained: How Encryption Protects Your Data

    Big thanks to TryHackMe for sponsoring this video. Learn Cyber Security with Practical Labs on TryHackMe:https://tryhackme.com/DavidBombalTech Use my code DAVIDTECH25 to get 25% OFF on Annual Subscription! Dr. Mike Pound joins David Bombal to explain symmetric encryption, AES, secret keys, VPN encryption, TLS, block ciphers, stream ciphers and why encryption is one of the most important building blocks in modern cybersecurity. In this video, Mike explains what encryption actually does: it takes readable plaintext and turns it into unreadable ciphertext so that only someone with the correct secret key can decrypt it. He breaks down how symmetric encryption works, why the same key is used to encrypt and decrypt, and why algorithms like AES are used everywhere from secure websites and VPNs to BitLocker and full disk encryption. You’ll learn why AES is so fast on modern CPUs, how keys interact with encryption algorithms, and why AES uses rounds of substitution and permutation to scramble data. Mike also explains the difference between block ciphers and stream ciphers, including AES, DES, Triple DES, ChaCha20 and older algorithms like RC4 and A5/1. The discussion also covers why symmetric encryption is used for bulk encryption in protocols like TLS and IPsec, why asymmetric encryption is used differently, and why you should never write your own encryption algorithm or implement your own AES code for real-world security. If you want to understand how encryption protects your data, how VPNs and secure web traffic work, and why AES is still one of the most important algorithms in cybersecurity, this is a great place to start. // Mike SOCIAL // X: / _mikepound YouTube Channel: / computerphile // YouTube Video REFERENCE //Password Cracking: Can a Rainbow table reverse a hashed password?: • Password Cracking: Can a Rainbow table rev... // David's SOCIAL // Discord: discord.com/invite/usKSyzb Twitter: www.twitter.com/davidbombal Instagram: www.instagram.com/davidbombal LinkedIn: www.linkedin.com/in/davidbombal Facebook: www.facebook.com/davidbombal.co TikTok: tiktok.com/@davidbombal YouTube: / @davidbombal Spotify: open.spotify.com/show/3f6k6gE...

    #580: Cisco's first Quantum Switch: What it means for you

    Big thanks to ‪@Cisco‬ for sponsoring this video and sponsoring my trip to Cisco Live Vegas 2026. In this deep dive into the future of networking, we explore the reality of quantum networking and Cisco's groundbreaking announcement of the world's first Universal Quantum Switch. Quantum computing is no longer just a buzzword; it's moving into the mainstream, bringing massive implications for network engineers and cybersecurity professionals in 2026 and beyond. We discuss why a quantum switch is essential for scaling distributed quantum computers and how it translates different quantum modalities, acting as a universal fabric. We also break down the quantum stack, from entanglement sources generating 200 million photon pairs per second to nanosecond switching speeds. Beyond the hardware, we tackle the elephant in the room: Shor's algorithm and the imminent threat to classical encryption (RSA/Diffie-Hellman). With "harvest now, decrypt later" attacks already happening and the January 2027 CNSA 2.0 compliance deadline approaching, we cover exactly how you can prepare using post-quantum cryptography (PQC). Finally, we explore fascinating real-world applications, including high-frequency trading advantages, unbreakable eavesdropper detection using the no-cloning theorem, and secure position verification. // Ramana Kompella’s SOCIAL // LinkedIn: / rkompella // Website REFERENCE // https://outshift.cisco.com/ // Videos REFERENCE // • Cisco Quantum Summit 2026 - Quantum Data C... https://event.on24.com/wcc/r/5305787/... // David's SOCIAL // Discord: discord.com/invite/usKSyzb Twitter: www.twitter.com/davidbombal Instagram: www.instagram.com/davidbombal LinkedIn: www.linkedin.com/in/davidbombal Facebook: www.facebook.com/davidbombal.co TikTok: tiktok.com/@davidbombal YouTube: / @davidbombal Spotify: open.spotify.com/show/3f6k6gE...
