In Part-2 Network Security Fundamentals, The Network DNA expands the conversation beyond technical tools to highlight the human and physical elements of a strong security program. The article underscores that even the best defensive technologies can fall short without well-trained users and strict physical protections for critical infrastructure. By prioritizing user awareness, security training, and physical access control, organizations can reduce common risks like phishing, accidental data exposure, and unauthorized entry into secure areas.
If you’ve ever had your computer suddenly shut off during a storm or brief power flicker, you already know how frustrating—and potentially damaging—it can be. That’s where a UPS (Uninterruptible Power Supply) comes in. Think of it as a safety net for your electronics. Instead of your system instantly losing power, a UPS provides temporary battery backup, giving your equipment enough time to stay running or safely shut down. For anyone who relies on computers, servers, or networking gear, that small buffer can make a huge difference.
Mozilla is rolling out a free built-in VPN directly into Firefox with the upcoming Firefox 149 update, set to start releasing on March 24, 2026.
Here's the key details from recent announcements:
It's browser-only (routes just your Firefox traffic through a proxy to hide your IP address and approximate location—no full-device protection like their paid Mozilla VPN).
Completely free, no subscription or extra downloads needed, and Mozilla emphasizes it's built on their privacy principles (unlike some sketchy free VPNs out there).
At launch, you'll get 50GB of data per month.
Initially available only in the US, UK, France, and Germany (likely expanding later).
This is part of a bigger Firefox 149 update that also includes things like split-screen browsing (Split View), tab notes, better AI feature controls, a visual refresh, and a new mascot named Kit.
For years, Windows users who needed administrative privileges in the terminal had to jump through a few awkward hoops—usually launching an entirely new “Run as administrator” window or wrestling with the clunky runas command. The article explains how Microsoft has finally embraced a much simpler approach by introducing the familiar sudo command to Windows 11. Borrowed from the Linux world, sudo allows users to run a single command with elevated privileges without turning the entire terminal session into an administrative free-for-all.
If you’ve ever deployed Wi-Fi and thought, “Well… it works most of the time,” this webinar is for you. “Wi-Fi Decoded: Wireless Design Best Practices” from Ekahau dives into the real science behind building reliable wireless networks. The session breaks down the fundamentals of wireless design—from RF behavior and coverage planning to avoiding common deployment mistakes that can quietly sabotage performance. Instead of relying on guesswork or trial-and-error, attendees will learn proven strategies used by experienced wireless engineers to build networks that actually perform the way users expect.
Throughout the webinar, the presenters walk through practical design approaches that help engineers plan better networks from the start. Expect insights into things like proper access point placement, understanding signal propagation, and designing for both coverage and capacity—two things that don’t always go hand-in-hand in Wi-Fi deployments. The session focuses on real-world lessons and examples that highlight why small design decisions can have a huge impact on roaming, interference, and overall user experience.
Whether you’re a wireless professional, network engineer, or someone who simply wants to stop hearing complaints about “slow Wi-Fi,” this webinar is packed with practical knowledge you can put to use immediately. If you want to design smarter networks, avoid costly mistakes, and finally understand what’s really happening in the airwaves, this event is well worth your time. Think of it as a crash course in turning your Wi-Fi from “meh” to actually impressive. #EKAHAU
