Every time you visit your bank, check your email, log into a shopping site, or open a secure web app, there’s an invisible browser protection working behind the scenes: HSTS — HTTP Strict Transport Security. In this episode of Technically U, we break down how HSTS protects billions of web sessions from one of the most elegant and dangerous network attacks ever demonstrated: SSL stripping. Back in...

DNS over HTTPS (DoH) encrypts the internet's phonebook—and it's breaking traditional network security. Here's what IT professionals need to know about DoH in 2026, why enterprises are concerned, and how to adapt.🔐 WHAT IS DNS OVER HTTPS:THE PROBLEM DoH SOLVES:- Traditional DNS = plaintext on port 53 (unencrypted since 1983)- ISPs, network operators, anyone on WiFi can see every domain...

🔐 Are your containers actually secure… or just assumed to be? In this episode of Technically U, we take a deep, structured dive into Container Security, breaking down how modern environments built on Docker and Kubernetes are secured—and more importantly, how they’re attacked. Containers have revolutionized application deployment, but they’ve also introduced an entirely new security model. Unlike...

Have you ever logged into your bank account and seen the message: “We don’t recognize this device”?That message may be powered by one of the most important cybersecurity tools most people have never heard of: device fingerprinting. In this episode of Technically U, we break down how websites, banks, apps, payment platforms, and security systems can recognize your device based on clues like your br...

Your Zoom call, WebEx meeting, VoIP phone conversation, and WebRTC video chat may all be encrypted — but they are not using HTTPS. Why? Because HTTPS relies on TLS over TCP, while real-time communications usually run on UDP. In this episode of Technically U, we break down DTLS — Datagram Transport Layer Security — the encryption protocol that makes secure real-time communication possible. DTLS giv...

AI agents are changing the workplace faster than most people realize. Unlike AI assistants such as ChatGPT, Claude, Gemini, or Copilot, AI agents do more than answer questions — they can take action inside business systems, complete workflows, update records, process requests, and make decisions within defined rules. In this episode of Technically U, we break down the real differences between AI a...

What if the technology powering BitTorrent, IPFS, and blockchain networks… is fundamentally insecure? In this episode of Technically U, we take a deep dive into Distributed Hash Table (DHT) security—and uncover why one of the internet’s most important decentralized technologies still faces unsolved security challenges after more than 20 years of research. DHTs enable peer-to-peer networking withou...

Who is allowed on your network—and how is that decision made? In this episode of Technically U, we break down IEEE 802.1X, the powerful security framework behind Network Access Control (NAC) that determines whether devices can connect to your wired or wireless network. Whether you're plugging into an Ethernet port or connecting to corporate Wi-Fi, 802.1X is working behind the scenes to authent...

🔐 Is your private network actually secure… or just private? In Part 3 of our Wavelength Services series on Technically U, we dive into encrypted Wavelength services—and why security at the optical layer is becoming critical for modern enterprise networks. Even with HTTPS, VPNs, and application-layer encryption, your data still travels across carrier-owned fiber infrastructure. And yes—fiber tappi...

⚡ Think your network is redundant? It might not be. In Part 2 of our Wavelength Services series on Technically U, we go beyond the basics and dive into the engineering decisions that determine whether your network survives a failure—or goes down hard. If you’re investing in 100G or 400G Wavelength (Wave) services, understanding protection, failover, and restoration is critical. Many organizations...

🌐 What is a Wavelength service—and why are enterprises, cloud providers, and financial networks relying on it? In this episode of Technically U, we break down Wavelength services (Wave / DWDM circuits)—the high-capacity optical connections that power data center interconnects, cloud infrastructure, and ultra-low latency networks. If you’ve ever heard someone say “we might need a Wave” and weren’t...

Key Takeaways: Most people don't need RFID blocking for credit cards Focus security on: transaction alerts, statement monitoring, strong passwords, 2FA, avoiding phishing Car key fobs SHOULD be stored in Faraday bags (real threat) Security theater: Products that provide feeling of security without actual protection Contactless payment becoming more secure with biometric authentication Don'...

Key Takeaways: RFID skimming accounts for less 0.01% of credit card fraud UK reported zero confirmed cases (2023-2024) Criminals use easier, more profitable methods (data breaches, phishing, buying stolen data) Passports have built-in RFID shielding when closed Car key fobs ARE vulnerable to relay attacks (legitimate concern) RFID-blocking products work but quality varies Aluminum foil works but i...
