Network Simulation – Cisco VIRL Now Available in the Cloud

There has been a lot happening around VIRL the last few weeks. A new release of VIRL just got released and today the VIRL team announced that they are adding support for running VIRL in the cloud.

Cisco has chosen to work together with Packet, a bare metal cloud provider. This is how Packet describes themselves.

At Packet, we're out to build a better internet by supercharging the container revolution with smart, API-driven bare metal. Our platform brings the price and performance benefits of bare metal servers to the cloud, powering highly-available performance workloads through a unique, never-congested network.

The following picture summarizes why Cisco has chosen Packet.

Compared to Amazon AWS, Packet is a bare metal cloud provider which means that the resources you rent will be dedicated to you. Packet does not run any hypervisors, meaning that the workloads are not virtualized.

If you have an existing install of VIRL, you can use Terraform by Hashicorp to provision your new VIRL server at Packet. I had never heard of Terraform before, this is how Hashicorp describes Terraform.

Today we announce Terraform, a tool for safely and efficiently building, combining, and launching infrastructure. From  Continue reading

Use Linux? Stop what you’re doing and apply this patch

A buffer-overflow vulnerability uncovered Tuesday in the GNU C Library poses a serious threat to countless Linux users.Dating back to the release of glibc 2.9 in 2008, CVE-2015-7547 is a stack-based buffer overflow bug in the glibc DNS client-side resolver that opens the door to remote code execution when a particular library function is used. Software using the function can be exploited with attacker-controlled domain names, attacker-controlled DNS servers or man-in-the-middle attacks.Glibc, which was also at the core of the "Ghost" vulnerability found last year, is a C library that defines system calls and other basic functions on Linux systems. Its maintainers had apparently been alerted of the new problem last July, but it's not clear if any remediation effort was launched at that time.To read this article in full or to leave a comment, please click here

How Shared Spectrum Can Improve In-Building Cellular

Juan Santiago By: Juan Santiago, Director of Product Management

You’ve been there before: You popped into a store and wanted to look something up on your smartphone while waiting in line. However, the cell signal shows just one lousy bar. You consider logging on to Wi-Fi but there are multiple inconvenient steps that aren’t worth the hassle while you’re waiting in line. Nope, you’ll just wait to go back outside and go somewhere else next time.

Why can’t Wi-Fi be as simple as pulling the phone out of your pocket, like cellular? Or, better yet, why can’t cellular just be everywhere Wi-Fi is, including deep inside buildings? The answer lies in a little-known fact about cellular: Your phone company owns the right to use the cellular airwaves everywhere, even if, as in the example above, it’s not actually using them where you happen to be. 

You may think that the store, realizing that you may never come back, would be willing to spend a little cash for better cell service, but it can’t. The store doesn’t own the right to use the airwaves inside its walls, thus it must work with each phone company individually to convince them to install a Continue reading

Should Technology Mirror Business?

The essence of SDN is to create a software model of the current data network business. This quantitative model is based on volumes of data: what ‘bandwidth’ resources do I have (i.e. supply), and how can I give different quantities of this ‘bandwidth’ to different users and uses (i.e. demand)? -via circleid

I’ve been in information technology since the early 1990’s, and it’s always been like this: business tells IT what to do, and IT does it. In other words, we make technology mirror business. Which is a fine formula for success, so long as you think business is the engine of innovation. The problem is innovation doesn’t come from one department or place. In fact, innovation most often comes from the intersection of two or more things. Think about it.

When did cars first start being innovative? When they combined the technology that existed in the latest horse drawn carriages with the latest in industrial technology, including internal combustion engines and assembly line production. All three of these came from someplace else—many people don’t know the idea of interchangeable parts came out of the firearms world, rather than the automotive industry. When did innovation come into the Continue reading

Worth Watching: The Economics of the Internet

Old economics explains the new economy well. When we buy something, we spend time and money searching for it, comparing it with other products, negotiating a price, and ensuring that we get what we paid for. This is what economists call ‘transaction costs.’ The internet dramatically reduces these costs, making it cheaper for people, businesses and governments to do business. -via the World Bank

Xen’s latest hypervisor updates are missing some security patches

The Xen Project released new versions of its virtual machine hypervisor, but forgot to fully include two security patches that had been previously made available.The Xen hypervisor is widely used by cloud computing providers and virtual private server hosting companies.Xen 4.6.1, released Monday, is flagged as a maintenance release, the kind that are put out roughly every four months and are supposed to include all bug and security patches released in the meantime."Due to two oversights the fixes for both XSA-155 and XSA-162 have only been partially applied to this release," the Xen Project noted in a blog post. The same is true for Xen 4.4.4, the maintenance release for the 4.4 branch that was released on Jan. 28, the Project said.To read this article in full or to leave a comment, please click here

Should you worry about the Internet of Hackable Things?

If 2015 was the year of the Internet of Things, 2016 could be the year of the hacked Internet of Things. That could mean a lot of headaches for CIOs, whether they're fans of these new devices themselves or will be dealing with employees connecting them at work and managing the potential security exposure that brings. "The issue to date is that devices are vulnerable just by the fact that they exist and can connect to the Internet," says Jerry Irvine, member of the U.S. Chamber of Commerce’s Cybersecurity Leadership Council and CIO of Prescient Solutions. "Anybody can get to a device if you don't secure them properly." To read this article in full or to leave a comment, please click here

How to prevent shadow IT
