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

Event-Driven Ansible became generally available in Ansible Automation Platform 2.4. As part of the release, Red Hat Insights and Ansible teams collaborated to implement and certify a Red Hat Insights collection integrating Insights events as a source of events for Ansible Automation Platform. This provides a consistent way to receive and handle events triggered from Insights to drive and track automation within the Ansible Automation Platform. The collection is available for installation on Ansible automation hub.
In this article, we explore how to get, configure and use the Red Hat Insights collection for Event-Driven Ansible, and provide an end-to-end example of an automation flow using Ansible Automation Platform and its Event-Driven Ansible functionality. Our goal is to automate the creation of a ServiceNow incident ticket with all relevant information when malware is detected by Insights on one of our Red Hat Enterprise Linux (RHEL) systems. We show how we can track and audit all automation from the Event-Driven Ansible controller as part of Ansible Automation Platform.
In a previous article, we looked at exposing and consuming Insights events to drive automation with Event-Driven Ansible. We validated that events triggered Continue reading
Starting on Aug 25, 2023, we started to notice some unusually big HTTP attacks hitting many of our customers. These attacks were detected and mitigated by our automated DDoS system. It was not long however, before they started to reach record breaking sizes — and eventually peaked just above 201 million requests per second. This was nearly 3x bigger than our previous biggest attack on record.
Concerning is the fact that the attacker was able to generate such an attack with a botnet of merely 20,000 machines. There are botnets today that are made up of hundreds of thousands or millions of machines. Given that the entire web typically sees only between 1–3 billion requests per second, it's not inconceivable that using this method could focus an entire web’s worth of requests on a small number of targets.
This was a novel attack vector at an unprecedented scale, but Cloudflare's existing protections were largely able to absorb the brunt of the attacks. While initially we saw some impact to customer traffic — affecting roughly 1% of requests during the initial wave of attacks — today we’ve Continue reading
