A few days after I published the EBGP session protection lab, Jeroen van Bemmel submitted a pull request that added TCP-AO support to netlab. Now that the release 1.6.3 is out, I could use it to build the Protect BGP Sessions with TCP Authentication Option (TCP-AO) lab exercise.
Today's Day Two Cloud covers highlights from a recent Edge Field Day event. Ned Bellavance was a delegate at the event and will share perceptions and insights based on presentations from the event. Topics include a working definition of edge, the constraints of hosting infrastructure in edge locations (power, space, network connectivity and others), and operational models for running software and services in these environments.

Back in the early 2000s, store and forward networking was used by both market data providers, exchanges and customers executing electronic trading applications where the lowest latency execution can make the difference in a strategy from a profit to a loss. Moving closer to the exchange to reduce link latency, eliminating any unnecessary network hops, placing all feed handler and trading execution servers on the same switch to minimize transit time, and leveraging high-performance 10Gb NICs with embedded FPGAs all contributed to the ongoing effort to squeeze out every last microsecond to execute trades and gain a performance edge.
In this podcast episode, Johna and I discuss the concept of technical debt. We provide different definitions of technical debt, with me focusing on the inability to switch solutions easily and Johna emphasizing the trade-off between immediate speed and long-term efficiency. We give examples of technical debt, such as outdated systems and insecure infrastructure, and […]

Today on the Tech Bytes podcast, we talk with sponsor Palo Alto Networks about SD-WAN for retail locations. From securing payment card data to supporting customer Wi-Fi to connecting a multitude of IoT devices, a secure, reliable WAN is a must for retail. We talk with Palo Alto Networks about how SD-WAN can help retail locations get and keep shoppers in stores.

It feels like the cybersecurity space is getting more and more crowded with breaches in the modern era. I joke that on our weekly Gestalt IT Rundown news show that we could include a breach story every week and still not cover them all. Even Risky Business can’t keep up. However, the defenders seem to be gaining on the attackers and that means the battle lines are shifting again.
A recent article from The Register noted that dwell times for detection of ransomware and malware hav dropped almost a full day in the last year. Dwell time is especially important because detecting the ransomware early means you can take preventative measures before it can be deployed. I’ve seen all manner of early detection systems, such as data protection companies measuring the entropy of data-at-rest to determine when it is no longer able to be compressed, meaning it likely has been encrypted and should be restored.
Likewise, XDR companies are starting to reduce the time it takes to catch behaviors on the network that are out of the ordinary. When a user starts scanning for open file shares and doing recon on the network you can almost guarantee they’ve Continue reading
