Review: Consider VPN services for hotspot protection

Virtual private networks have many uses. Typically, businesses deploy VPNs so employees can securely access the corporate network from outside the office. However, we’ve seen a rise in third-party VPN services that use the same underlying technology, the encrypted tunnel, to simply provide a secure Internet connection. The main window of the Freedome Windows application shows a big circle which tells you the connection status and serves as a connect/disconnect button. On the sides of that, you see the amount of traffic you have sent/received and the number of harmful sites and tracking attempts blocked while connected to the service. Below you see the VPN location, which you can click on to change to one of 21 countries. You can’t choose the exact city, but can select available regions, such as West or East Coast of the U.S.To read this article in full or to leave a comment, please click here(Insider Story)

7 VPN services for hotspot protection

VPNsVirtual private networks (VPNs) have many uses. When connected to a VPN service, the websites you access think you’re at the location where the VPN server is located. This can help anonymize your Internet traffic so it’s much harder for websites to track your personal browsing history. This also allows you to access content that’s restricted where you are currently located, such as Netflix or Hulu when traveling overseas. We evaluated seven third-party VPN services. Here are the individual reviews: On our Android device, we installed the Avast SecureLine app, version 1.0.7704. By default, you only see a status icon for the app on the status bar of Android and on the notification drawer when you’re connected to the service. However, you can optionally enable the icon and notification to be present when disconnected as well. The Android app is also very simple. There’s no shortcut to any help or documentation within the Android app or Windows application, but it really isn’t needed given how simple the apps and service are. Additionally, your Internet traffic would be encrypted when you’re on unsecured Wi-Fi networks, such as public hotspots. This prevents local eavesdroppers from capturing your browsing history and logins. Continue reading

Kubernetes Authentication plugins and kubeconfig

Kubernetes offers several different authentication mechanisms or plugins.  The goal of this post is to review each of them and provide a brief example of how they work.  In addition, we’ll talk about the ‘kubeconfig’ file and how it’s used in association with authentication plugins.

Note: In theory there’s no requirement to use any of these authentication plugins.  With the proper configuration, the API server can accept requests over HTTP on any given insecure port you like.  However – doing so is insecure and somewhat limiting because some features of Kubernetes rely on using authentication so it’s recommended to use one or more of the following plugins.

Kubernetes offers 3 default authentication plugins as of version 1.0.  These plugins are used to authenticate requests against the API server.  Since they’re used for communication to the API, that means that they apply to both the Kubelet and Kube-Proxy running on your server nodes as well as any requests or commands you issue through the kubectl CLI tool.  Let’s take a look at each option…

Client Certificate Authentication
This is the most common method of authentication and is widely used to authentication node back Continue reading

The Power of Test-Driven Network Automation

Over the past few years, I’ve seen (and contributed to) a rise of real network engineers taking on the new and sometimes challenging world of network automation. Every time I check in on Jason Edelman’s Network Automation Slack channel, I’m very happy to see the sheer number of folks asking questions, trying to get the the concepts and tools of network automation working in their own environment. For many, this is all very new, and there’s a lot to soak up.

For many, this is all very new, and there’s a lot to soak up. Linux networking has broken onto the scene in a big way. We’ve started using text formats like YAML and Jinja2 to template out network configurations to make more consistent network changes. We’ve started using tools like Ansible to drive those changes in a meaningful way to our network infrastructure. It’s clear that these ideas are useful, and are taking hold in a big way.

At this point, I’d like to ask you this question; with all of this tooling, which admittedly helps us achieve consistency of change, does it really ensure the success of a change? How do we even define success? At what point can we sit back and be able to truly say, “that change did not Continue reading

After New York, gigabit public Wi-Fi comes to Berlin

Ask someone in Hanover, Germany, where to find the best public Wi-Fi and the answer may well be "In Berlin," 250 kilometers to the East.That's because free gigabit Wi-Fi for Berliners was one of the first new services announced at the Cebit trade show in Hanover this week.New York got its first taste of free gigabit Wi-Fi in January, when CityBridge turned on its first LinkNYC hotspots, which are gradually replacing payphones in the city.In Berlin, it's not a billboard-advertising-funded startup that's delivering the service, but an established telecommunications operator.To read this article in full or to leave a comment, please click here

Retrieving network elements backup from 5620 SAM

Last week I faced a routine (and quite common) task to get the latest backups of current configuration and BOF files for ~700 routers on a customers network. Sure thing sane man would use some automatization techniques, which could be: 5620 SAM scripts some scripting language to grab latest backups from the global NE backup location

Digiwell will teach you an NFC trick your old dog may already know

Patrick Kramer pulled back his sleeves and reached out an empty hand to offer his business card. His contact details appeared on the smartphone screen as if by magic, but it was a sufficiently advanced technology that made it happen. For an encore, he opened a locked door without a key. When anyone else touched the handle, it remained locked. Unlike other magicians, Kramer willingly explained the secret to the trick, which is so simple a dog could perform it: In the flesh between his left thumb and forefinger, he has inserted a tiny glass bead containing an NFC chip.To read this article in full or to leave a comment, please click here

Don’t feel comforted by an antivirus’s security certification

If you feel comforted by your antivirus vendor’s boast of having a certification from Verizon, then maybe you need to rethink that. Google Project Zero security researcher Tavis Ormandy says the methodology behind Verizon’s certification is “about as ridiculous as you would expect,” but vendors follow the gimpy guideline criteria (pdf), pay the fee to be certified and users tend to view the certification as some sign of excellence to be trusted.To read this article in full or to leave a comment, please click here
