Microsoft patches RHEL instances in Azure cloud

Microsoft has patched a vulnerability stemming from its configuration of Red Hat Enterprise Linux (RHEL) in the Azure public cloud that a customer discovered.+MORE AT NETWORK WORLD: How to compare costs between AWS, Azure and Google clouds +Microsoft Azure uses a process in which all instances of the RHEL operating system check back to a centralized system to ensure it is up to date. The customer, Ian Duffy in Ireland, found that he was able to access that master copy of RHEL, which could have allowed him or anyone else to implant a security vulnerability into the master copy of the program that would have propagated throughout any Azure customer using the OS.To read this article in full or to leave a comment, please click here

Not one, not two, but three undersea cables cut in Jersey

Sometime before midnight Monday (UK local time) a ship dropped its anchor and broke, not one, not two, but three undersea cables serving the island of Jersey in the English Channel. Jersey is part of the Channel Islands along with Guernsey and some smaller islands.

These things happen and that’s not a good thing. The cut was reported on the venerable BBC news website. For the telecom operators in Jersey (JT Global) this wasn’t good news. However looking at the traffic from Cloudflare’s point of view; we can see that while the cable cut removed the direct path from London to Jersey, it was replaced by the backup path from Paris to Jersey. The move was 100% under the control of the BGP routing protocol. It's a relief that there's a fallback for when these unpredictable events happen.

Here's a look at one network on the island.

The red traffic is being served from our London data center (the normal location for all Jersey traffic) and the blue traffic is coming from our Paris data center. The step could well be caused by either a delayed break in one of the cables or the Continue reading

The new Mirai strain has gone far beyond Deutsche Telekom

The latest strain of Mirai, the malware that’s been infecting internet routers from Germany’s Deutsche Telekom, has spread to devices in at least 10 other countries, according to security firm Flashpoint.The company has detected the new Mirai strain infecting internet routers and modems across the globe, including in the U.K., Brazil, Iran and Thailand.It’s still unclear how many devices have been infected, but Flashpoint estimates that as many as five million devices are vulnerable. “If even a fraction of these vulnerable devices were compromised, they would add considerable power to an existing botnet,” Flashpoint said in a Tuesday blog post.To read this article in full or to leave a comment, please click here

Netbox IPAM/DCIM – What all Network Engineers beg for!

We found it!!!

Have you ever sat at your desk, hoping on a miracle, that somebody somewhere will develop a fully comprehensive application for tracking network information???  I know I have, along with millions of other fellow network professional’s I have to assume.  What exactly am I referring to?  IP addresses, vlans, VRF’s, Rack Elevations and on and on and on.  We all have to keep up with this information, for most it is located in spreadsheets; some in notepads; others try to lock it all away in the vast empty space we call a brain.

So, the stage is set.  Yes, there are claims of applications that can keep track of what your CORE router IP address is and what vlan you assigned to one of your customers, or even where in the bloody rack it sits in relation to your other devices.  Some can even keep track of which VRF routing table your management lies in along with which physical port it connects to.  Going a little further, maybe the application claims to give you a basic map layout to which you can refer to…

BUT, very few paid applications actually combine most of these functions into one and very Continue reading

Pushing Back Against Cheap and Deep Storage

It is not always easy, but several companies dedicated to the supercomputing market have managed to retune their wares to fit more mainstream market niches. This has been true across both the hardware and software subsets of high performance computing, and such efforts have been aided by a well-timed shift in the needs of enterprises toward more robust, compute and data-intensive workhorses as new workloads, most of which are driven by dramatic increases in data volumes and analytical capabilities, keep emerging.

For supercomputer makers, the story is a clear one. However, on the storage side, especially for those select few …

A year after separation, HP and HPE are still trying to shed rust

Five years ago, then Hewlett-Packard CEO Leo Apotheker was derided for an abrupt plan to spin off the PC division from the mothership. It happened anyway in 2015, when the idea seemed more logical.The spin-off led to the creation of HP, which focuses on PCs and printers, and Hewlett Packard Enterprise, which focuses on enterprise hardware and the cloud. Now a year after the split, the companies are still trying to shed off the rust as they try to stand on their own legs.Growing pains have afflicted both companies as they try to find their identities. HP and HPE both had to change their business focuses and also shed excess fat, announcing layoffs last month within days of each other.To read this article in full or to leave a comment, please click here

New partner programs for AWS are aimed at growing Alexa, IoT, and more

While Amazon Web Services touts the self-service capabilities of its cloud, the company also works with a large number of channel partners to help companies migrate to and use its services. The cloud provider announced a suite of updates to its partner programs at its Global Partner Summit keynote in Las Vegas on Tuesday. The updates are focused on helping customers get increased use of Amazon’s cloud services and getting partners to invest further in AWS. The keynote was an opportunity for the cloud provider to make a hard sell to the companies that will help businesses adopt Amazon’s cloud services. Partners shouldn’t hedge their investment in the public cloud, but should instead commit to supporting one provider deeply and aggressively, AWS CEO Andy Jassy said.To read this article in full or to leave a comment, please click here

Worth Reading: Security and BYOD

According to the Identity Theft Resource Center, more than 169 million personal records were exposed as a result of 781 publicized security breaches across the financial, business, education, government and health-care sectors in 2015. As shocking as these numbers are, they may not fully convey the scope of the threat: Any company or consumer that connects to the Internet is at risk of becoming a victim of a cyberattack. The challenge of protecting networks from these attacks has been exacerbated by the bring-your-own-device phenomenon, which opens the door to new vulnerabilities for many organizations daily. More and more, business is taking place over personal devices as employees work from home or travel. For some staff members, relying on their own laptops, tablets and smartphones is simply a matter of personal preference. —Data Center Journal

Tips for building SD-WANs

The substantially high cost of MPLS circuits ($200-$400/Mbps/month) compared to easily deployed, lower cost broadband Internet (with a price tag of $1/Mbps/month) has triggered a shift in enterprise architectures to the software defined WAN. SD-WAN provides the flexibility to choose the most optimal transport and dynamically steer traffic over a mix of MPLS circuits, the public Internet, or even wireless LTE circuits.  The access transport selection depends on a variety of factors, including the type of application, traffic profile, security requirements, QoS and network loss and latency. When implemented correctly, SD-WAN truly has significant advantages: Faster service deployment, increased flexibility, unified management and improved application performance, to name a few. But, while familiarity about SD-WAN has increased over the last year, a survey by Silver Peak and IDG shows only 27% of small- to mid-sized enterprises have shifted to SD-WAN.To read this article in full or to leave a comment, please click here

Isolation technologies create an “air gap” to eliminate the risk of malware

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.Like the threat landscape itself, web gateways have changed over the years. Back in the 1990s, organizations primarily used them to prevent employees from wasting time surfing the web – or worse, from visiting gambling, adult and other unauthorized websites. Today web gateways do much more than enforce regulatory compliance and HR policies. Whether they are implemented on-premise or as cloud-based services, organizations rely on web gateways to thwart Internet-borne threats delivered through users’ browsers.To read this article in full or to leave a comment, please click here
