Meeting Madness, ONUG, and Software Defining All The Things

We’re going back to our roots here at Network Collective and that means we’re going to be spending more time chatting and less time with agendas. In this episode we discuss Russ’s impression of ONUG 2019 in Dallas, the team’s take on solving problems in a meeting, the value of meetings in general, and the slow but steady rise of SDN adoption in the enterprise.

BrandPost: What’s a Mobile-First Support Strategy, and Why Do You Need One?

Remote support has long been offered to customers on desktops and laptops, but with the rise of mobile devices, times are changing. If you haven’t already considered a mobile-first support strategy, now’s the time to create one.Most people spend an average of 5 hours a day on their mobile devices, a statistic that you won’t find too surprising if you’re reading this on a mobile device. Increasingly, we rely on our mobile devices in our personal and work lives, and in many cases, customers are ditching their laptops and moving entirely to mobile.It stands to reason that if mobile is where customers are, support teams should be there too. The problem is, remote support was originally created for desktops and is often offered through channels that aren’t always readily available to mobile users, like live chat. That’s why it makes sense for support teams to look at remote support from the other side: mobile-first. This allows you to create a remote support experience that’s consistent across web and mobile, including how tickets feed into the same queue for fast resolution, and how diagnostic data is presented for the device, operating system, network, and more. Doing so enables your Continue reading

Announcing Cloudflare Image Resizing: Simplifying Optimal Image Delivery

Announcing Cloudflare Image Resizing: Simplifying Optimal Image Delivery

In the past three years, the amount of image data on the median mobile webpage has doubled. Growing images translate directly to users hitting data transfer caps, experiencing slower websites, and even leaving if a website doesn’t load in a reasonable amount of time. The crime is many of these images are so slow because they are larger than they need to be, sending data over the wire which has absolutely no (positive) impact on the user’s experience.

To provide a concrete example, let’s consider this photo of Cloudflare’s Lava Lamp Wall:

On the left you see the photo, scaled to 300 pixels wide. On the right you see the same image delivered in its original high resolution, scaled in a desktop web browser. They both look exactly the same, yet the image on the right takes more than twenty times more data to load. Even for the best and most conscientious developers resizing every image to handle every possible device geometry consumes valuable time, and it’s exceptionally easy to forget to do this resizing altogether.

Today we are launching a new product, Image Resizing, to fix this problem once and for all.

4 vulnerabilities and exposures affect Intel-based systems; Red Hat responds

Four vulnerabilities were publicly disclosed related to Intel microprocessors. These vulnerabilities allow unprivileged attackers to bypass restrictions to gain read access to privileged memory. They include these common vulnerabilities and exposures (CVEs): CVE-2018-12126 - a flaw that could lead to information disclosure from the processor store buffer CVE-2018-12127 - an exploit of the microprocessor load operations that can provide data to an attacker about CPU registers and operations in the CPU pipeline CVE-2018-12130 - the most serious of the three issues and involved the implementation of the microprocessor fill buffers and can expose data within that buffer CVE-2019-11091 - a flaw in the implementation of the "fill buffer," a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache [ Also read: Linux hardening: a 15-step checklist for a secure Linux server ] Red Hat customers should update their systems Security updates will degrade system performance, but Red Hat strongly suggests that customers update their systems whether or not they believe themselves to be at risk.To read this article in full, please click here

Heavy Networking 449: Web Application Firewall Fundamentals

Today's Heaving Networking episode delves into Web application firewalls (WAFs) with guest Scott Hogg. We examine how WAFs differ from typical firewalls, the security problems they're trying to solve, how attackers try to bypass them, operational challenges, WAFs and cloud applications, and more.

Las Vegas targets transport, public safety with IoT deployments

The city of Las Vegas’ pilot program with NTT and Dell, designed to crack down on wrong-way driving on municipal roads, is just part of the big plans that Sin City has for leveraging IoT tech in the future, according to the city's director of technology Michael Sherwood., who sat down with Network World at the IoT World conference in Silicon Valley this week.The system uses smart cameras and does most of its processing at the edge, according to Sherwood. The only information that gets sent back to the city’s private cloud is metadata – aggregated information about overall patterns, for decision-making and targeting purposes, not data about individual traffic incidents and wrong-way drivers.To read this article in full, please click here
