Keysight: How to Overcome the Darkside of Moving Apps to the Cloud

First up, the paper kicks off by acknowledging the big promise of public cloud platforms: faster time-to-market, flexibility, scalable business apps, and so on. But it quickly pulls back the curtain and warns that many organizations hit a “dark side” — unexpected performance issues, runaway costs, downtime, and diminished ROI. In fact, the data shows a hefty chunk of companies are already pulling workloads back on-premises because the cloud move didn’t go as expected.

Then, it digs into the root of the issues. A big culprit: organizations leap into the cloud without a clear strategy for which apps should move and why. That can lead to costly cycles of move → undo → re-move. It also lists core problem areas: security concerns, performance degradation, vendor lock-in, multi-cloud complexity, and hidden costs. The paper emphasizes that the cloud isn’t automatically better just because “cloud” sounds good — you still need to plan thoughtfully.

The next part of the paper deals with getting visibility and monitoring in place. If you move apps to the cloud (or mix cloud + on-premises), you must still see what’s going on: traffic, latency, application performance, security anomalies. Without that visibility you’re flying blind and can’t detect problems or validate that your cloud provider is delivering. It talks about building a three-layer visibility architecture (data access, control plane, monitoring layer) plus active monitoring tools and synthetic tests to stress applications and ensure SLAs really hold up.

Finally, the paper offers a pragmatic conclusion: there’s no one-size-fits-all answer. If cloud doesn’t make sense for some workloads, moving them back on-premises or using a hybrid model might be the best move. The goal is to pick the right tool for the right job, not just chase hype. It emphasizes that visibility isn’t optional — you must have a scalable architecture for it — and that a hybrid approach may give you the flexibility to harness cloud benefits when they work, and keep control when they don’t.

Adding a Wireshark icon on your Kali Linux desktop

 Having a Wireshark icon right on your Kali Linux desktop might seem like a small convenience, but it can make a big difference in efficiency. Instead of navigating through menus or typing commands to launch the tool, one click instantly opens Wireshark, getting you straight to packet analysis. When working in fast-paced environments like penetration testing or incident response, that quick access can be the difference between catching a critical packet and missing it.

A desktop icon also serves as a constant reminder of one of the most powerful tools in your cybersecurity toolkit. Wireshark is essential for inspecting traffic, identifying anomalies, and diagnosing network issues. By keeping it visible and easily accessible, you’re more likely to use it frequently — reinforcing good habits and encouraging continuous network monitoring rather than waiting until something breaks.

Finally, a Wireshark desktop shortcut simplifies multitasking and experimentation. Kali users often juggle multiple tools and terminal windows, so launching Wireshark with a single click keeps workflows smooth and organized. Whether you’re capturing live traffic, replaying saved traces, or analyzing suspicious packets, that quick-start icon saves time and helps maintain focus — a subtle yet effective way to boost productivity in your cybersecurity operations.

"Scouring the dark web for leaks of sensitive data

Four in five small businesses have suffered a recent data breach. And a single incident can cost a small firm over $1 million. So why don't we hear more data breach news?

Proton isn’t waiting for breaches to be reported. Instead, we go directly to the dark web, capturing and sharing leaks in real time — and helping small businesses to protect themselves."

Starting Your VirtualBox Image from the command line Is a Game Changer

Starting your VirtualBox Linux image from the command line may seem like a task for advanced users, but it offers real advantages in speed, control, and automation. Instead of waiting for the VirtualBox GUI to load and manually selecting your virtual machine, a simple command like VBoxManage startvm "UbuntuServer" --type headless launches it instantly. This approach streamlines your workflow, especially if you frequently run or test multiple virtual environments.

Another major benefit is automation. Command-line control allows you to integrate VM operations into scripts or batch files. You can start, stop, snapshot, or even clone your Linux images automatically as part of a larger process — for example, preparing a test environment or running a nightly build. This level of automation isn’t just efficient; it’s essential for developers, system admins, and IT professionals who manage several VMs at once.

Finally, running your VirtualBox image from the terminal can reduce overhead and improve performance. When launched in headless mode, the VM operates without the graphical interface, freeing up system resources for the guest OS or other tasks. This is particularly valuable on servers or lightweight setups where every bit of CPU and memory matters. In short, the command line offers a faster, cleaner, and more powerful way to manage your VirtualBox Linux systems.

Fine-Tuning Your Network: How to Set Your Windows MTU to 1400 for Smoother Connections

 

Your computer’s **MTU (Maximum Transmission Unit)** defines the largest packet size your system can send over the network without needing to be fragmented. In simple terms, it controls how much data travels in each burst across your connection. If your MTU is too high, packets may get fragmented or dropped, leading to slower speeds or connection issues. Adjusting your MTU to the optimal value—like **1400 bytes**—can make a noticeable difference in stability and performance, especially when troubleshooting VPNs, gaming latency, or file transfer interruptions.

To change the MTU on a Windows computer, you’ll start by **opening Command Prompt as Administrator**. Simply type “cmd” in your Windows search bar, right-click on **Command Prompt**, and select **Run as administrator**. Next, type the command `netsh interface ipv4 show subinterfaces` and press **Enter**. This command lists all your active network interfaces and their current MTU values, allowing you to identify the name of the connection you want to modify (for example, “Wi-Fi” or “Ethernet”).

Once you’ve identified your interface, you can change its MTU with a single command. Type the following line, replacing “Wi-Fi” with your interface name. 

netsh interface ipv4 set subinterface "Wi-Fi" mtu=1400 store=persistent

Press **Enter** to apply the change. The “store=persistent” option ensures your new MTU value remains active even after a reboot. After running this command, you can confirm the change by retyping `netsh interface ipv4 show subinterfaces` to verify that your MTU now shows as 1400.

Changing your MTU can help eliminate connection bottlenecks and packet fragmentation that slow down your network performance. It’s especially beneficial for **VPNs, gaming, or remote work setups**, where even small inefficiencies can cause lag or disconnections. Remember that the best MTU size depends on your network environment—1400 is a safe, compatible value for most users, but you can test other sizes if needed. With this quick tweak, your Windows PC can enjoy more stable, reliable, and responsive network performance.
