Spectre/Meltdown: Long Time No Read

It is time again to talk about the most prominent security vulnerabilities of 2018, whose horror at the beginning of the year haunted the Internet, only to turn out to not be so horrible afterwards. In the end it's something that can be reported on, but which will not lead to the end of the world. Here are some facts about Spectre & Meltdown, covering everything that has been going on since our last article. But first, a brief etymological digression.

When Alert Notifications Fail: How PRTG Hosted by Paessler Can Help

The basis of any network monitoring solution is alert notifications. You need them to know when there's a problem with your infrastructure. And, when setting up your monitoring solution, there is a fundamental problem that you will have to consider when it comes to notifications: if your infrastructure crashes and no longer accesses a connection to the Internet, how will you be notified? Because traditionally, your monitoring software is onsite. And onsite is down, with no means to communicate with the outside world. Oops.  This leads us to the age-old philosophical question: Like a tree falling in the forest, if your network fails and you don't get the notifications, did it really fail?

Track Your GDPR Compliance with PRTG

Apart from some events in the world of politics, hardly any topic has been as intensely debated in the past few weeks as the introduction of the new General Data Protection Regulation (GDPR), which came into force on May 25, 2018.

LPWA: A New Technology? Not as New as It Seems.

LPWA (or LPWAN - the “N” stands for Network but both terms mean the same technology) and Sigfox: you've been hearing and reading about it a lot lately. We have already had an initial overview in our blog, but here we jump between several topics within the generic term LPWA(N).

What makes a star? Is it that they're late every time they shoot? Is it the excessive make-up pauses while the scriptwriter is sent out to get an espresso? Or is it the spontaneous script modifications?  If that is so, then I guess we've created a star.

Wait, Geek What? Tell Us Your Opinion!

I believe the state of a society can be measured by the unofficial holidays it celebrates. Let's put it this way: In the 21st century there is a "Ditch New Years Resolutions Day" (January 17th), a "Compliment Your Mirror Day" (July 3rd) and a "Punk for a Day Day" (October 25th). Not to mention that even Disney characters seem to have their own day of honor. You' re into Donald Duck? Then save June 9th! All this is proof enough for me that mankind is genuinely screwed. But maybe there is hope: The International Geek Pride Day seems to rise from the vacuum of pointless pseudo holidays as the shining figurehead of a real, meaningful feast.

Monitoring Physical Security Systems

The basic principles of physical security systems have been around for decades, and have not changed that much: surveillance, intrusion detection, and triggering alarms in case of breaches or anomalies still form the basis of any security installation. What has changed, however, is the technology driving these basic principles, as digitization has changed the very bones of security systems. Along with this digitization, new challenges have arisen. In this post, we take a look at some of these, and how to mitigate them.

The Next Level: Get Our IPv6 Cheat Sheet

How Cryptojacking Impacts You, and What You Can Do About It

Late in 2017, we witnessed a frenzy in the cryptocurrency markets as the price of Bitcoin nearly reached $18,000 USD. This led to a gold rush mentality as everyone looked to cash in on this new commodity. Unfortunately, this gave rise to a new type of malware: cryptojacking.
