Are SD-WAN security concerns warranted?

Are software-defined WAN security features sufficient to handle the demands of most enterprises? That’s the question addressed by author and engineer Christoph Jaggi, whose SD-WAN security concerns were cited in a recent blog post on IPSpace. The short answer? No — primarily because of the various connections that can take place over an SD-WAN deployment.

“The only common elements between the different SD-WAN offerings on the market are the separation of the data plane and the control plane and the takeover of the control plane by an SD-WAN controller,” Jaggi said. “When looking at an SD-WAN solution, it is part of the due diligence to look at the key management and the security architecture in detail. There are different approaches to implement network security, each having its own benefits and challenges.”

Organizations contemplating SD-WAN rollouts should determine whether prospective products meet important security thresholds. For example, products should support cryptographic protocols and algorithms and meet current key management criteria, Jaggi said.

Wireless ain’t nothing without the wire

You can have the fanciest access points and the flashiest management software, but without good and reliable wiring underpinning your wireless LAN, you’re not going to get very far. So said network engineer Lee Badman as he recounted a situation where a switch upgrade caused formerly reliable APs to lurch to a halt.

“I’ve long been a proponent of recognizing [unshielded twisted pair] as a vital component in the networking ecosystem,” Badman said. Flaky cable might still be sufficient in a Fast Ethernet world, but with multigig wireless now taking root, old cable can be the source of many problems, he said.

For Badman, the culprit was PoE-related and once the cable was re-terminated and tested anew, the APs again worked like a charm. A good lesson.

The long tail and DDoS attacks

Now there’s something new to worry about with distributed denial of service, or DDoS, attacks. Network engineer Russ White has examined another tactic, dubbed tail attacks, which can just as easily clog networking resources.

Unlike traditional DDoS or DoS attacks that overwhelm bandwidth or TCP sessions, tail attacks concentrate on resource pools, such as storage nodes. In this scenario, a targeted node might be struggling because of full queues, White said, and that can cause dependent nodes to shut down as well. These tail attacks don’t require a lot of traffic and, what’s more, are difficult to detect.

For now, tail attacks aren’t common; they require attackers to know a great deal about a particular network before they can be launched. That said, they are something network managers should be aware of, White added.

Helping customers shift to a modern desktop – Microsoft 365 Blog

IT is complex. And that means it can be difficult to keep up with the day-to-day demands of your organization, let alone deliver technological innovation that drives the business forward. In desktop management, this is especially true: the process of creating standard images, deploying devices, testing updates, and providing end user support hasn’t changed much in years. It can be tedious, manual, and time consuming. We’re determined to change that with our vision for a modern desktop powered by Windows 10 and Office 365 ProPlus. A modern desktop not only offers end users the most productive, most secure computing experience—it also saves IT time and money so you can focus on driving business results.

Today, we’re pleased to make three announcements that help you make the shift to a modern desktop:

  • Cloud-based analytics tools to make modern desktop deployment even easier.
  • A program to ensure app compatibility for upgrades and updates of Windows and Office.
  • Servicing and support changes to give you additional deployment flexibility.

Analytics to make modern desktop deployment easier

Collectively, you’ve told us that one of your biggest upgrade and update challenges is application testing. A critical part of any desktop deployment plan is analysis of existing applications—and the process of testing apps and remediating issues has historically been very manual and very time consuming. Microsoft 365 offers incredible tools today to help customers shift to a modern desktop, including System Center Configuration Manager, Microsoft Intune, Windows Analytics, and Office Readiness Toolkit. But we’ve felt like there’s even more we could do.

Today, we’re announcing that Windows Analytics is being expanded to Desktop Analytics—a new cloud-based service integrated with ConfigMgr and designed to create an inventory of apps running in the organization, assess app compatibility with the latest feature updates of Windows 10 and Office 365 ProPlus, and create pilot groups that represent the entire application and driver estate across a minimal set of devices.

The new Desktop Analytics service will provide insight and intelligence for you to make more informed decisions about the update readiness of your Windows and Office clients. You can then optimize pilot and production deployments with ConfigMgr. Combining data from your own organization with data aggregated from millions of devices connected to our cloud services, you can take the guess work out of testing and focus your attention on key blockers. We’ll share more information about Desktop Analytics and other modern desktop deployment tools at Ignite.

Standing behind our app compatibility promise

We’re also pleased to announce Desktop App Assure—a new service from Microsoft FastTrack designed to address issues with Windows 10 and Office 365 ProPlus app compatibility. Windows 10 is the most compatible Windows operating system ever, and using millions of data points from customer diagnostic data and the Windows Insider validation process, we’ve found that 99 percent of apps are compatible with new Windows updates. So you should generally expect that apps that work on Windows 7 will continue to work on Windows 10 and subsequent feature updates. But if you find any app compatibility issues after a Windows 10 or Office 365 ProPlus update, Desktop App Assure is designed to help you get a fix. Simply let us know by filing a ticket through FastTrack, and a Microsoft engineer will follow up to work with you until the issue is resolved. In short, Desktop App Assure operationalizes our Windows 10 and Office 365 ProPlus compatibility promise: We’ve got your back on app compatibility and are committed to removing it entirely as a blocker.

Desktop App Assure will be offered at no additional cost to Windows 10 Enterprise and Windows 10 Education customers. We’ll share more details on this new service at Ignite and will begin to preview this service in North America on October 1, 2018, with worldwide availability by February 1, 2019.

Servicing and support flexibility

Longer Windows 10 servicing for enterprises and educational institutions
In April 2017, we aligned the Windows 10 and Office 365 ProPlus update cadence to a predictable semi-annual schedule, targeting September and March. While many customers—including Mars and Accenture—have shifted to a modern desktop and are using the semi-annual channel to take updates regularly with great success, we’ve also heard feedback from some of you that you need more time and flexibility in the Windows 10 update cycle.

Based on that feedback, we’re announcing four changes:

  • All currently supported feature updates of Windows 10 Enterprise and Education editions (versions 1607, 1703, 1709, and 1803) will be supported for 30 months from their original release date. This will give customers on those versions more time for change management as they move to a faster update cycle.
  • All future feature updates of Windows 10 Enterprise and Education editions with a targeted release month of September (starting with 1809) will be supported for 30 months from their release date. This will give customers with longer deployment cycles the time they need to plan, test, and deploy.
  • All future feature updates of Windows 10 Enterprise and Education editions with a targeted release month of March (starting with 1903) will continue to be supported for 18 months from their release date. This maintains the semi-annual update cadence as our north star and retains the option for customers that want to update twice a year.
  • All feature releases of Windows 10 Home, Windows 10 Pro, and Office 365 ProPlus will continue to be supported for 18 months (this applies to feature updates targeting both March and September).

In summary, our new modern desktop support policies—starting in September 2018—are:

Windows 7 Extended Security Updates
As previously announced, Windows 7 extended support is ending January 14, 2020. While many of you are already well on your way in deploying Windows 10, we understand that everyone is at a different point in the upgrade process.

With that in mind, today we are announcing that we will offer paid Windows 7 Extended Security Updates (ESU) through January 2023. The Windows 7 ESU will be sold on a per-device basis and the price will increase each year. Windows 7 ESUs will be available to all Windows 7 Professional and Windows 7 Enterprise customers in Volume Licensing, with a discount to customers with Windows software assurance, Windows 10 Enterprise or Windows 10 Education subscriptions. In addition, Office 365 ProPlus will be supported on devices with active Windows 7 Extended Security Updates (ESU) through January 2023. This means that customers who purchase the Windows 7 ESU will be able to continue to run Office 365 ProPlus.

Please reach out to your partner or Microsoft account team for further details.

Support for Office 365 ProPlus on Windows 8.1 and Windows Server 2016
Office 365 ProPlus delivers cloud-connected and always up-to-date versions of the Office desktop apps. To support customers already on Office 365 ProPlus through their operating system transitions, we are updating the Windows system requirements for Office 365 ProPlus and revising some announcements that were made in February. We are pleased to announce the following updates to our Office 365 ProPlus system requirements:

  • Office 365 ProPlus will continue to be supported on Windows 8.1 through January 2023, which is the end of support date for Windows 8.1.
  • Office 365 ProPlus will also continue to be supported on Windows Server 2016 until October 2025.

Office 2016 connectivity support for Office 365 services
In addition, we are modifying the Office 365 services system requirements related to service connectivity. In February, we announced that starting October 13, 2020, customers will need Office 365 ProPlus or Office 2019 clients in mainstream support to connect to Office 365 services. To give you more time to transition fully to the cloud, we are now modifying that policy and will continue to support Office 2016 connections with the Office 365 services through October 2023.

Shift to a modern desktop

You’ve been talking, and we’ve been listening. Specifically, we’ve heard your feedback on desktop deployment, and we’re working hard to introduce new capabilities, services, and policies to help you on your way. The combination of Windows 10 and Office 365 ProPlus delivers the most productive, most secure end user computing experience available. But we recognize that it takes time to both upgrade devices and operationalize new update processes. Today’s announcements are designed to respond to your feedback and make it easier, faster, and cheaper to deploy a modern desktop. We know that there is still a lot of work to do. But we’re committed to working with you and systematically resolving any issues. We’d love to hear your thoughts and look forward to seeing you and discussing in more detail in the keynotes and sessions at Ignite in a few weeks!

Microsoft pledges to cut carbon emissions by 75 percent by 2030 – Microsoft on the Issues

At Microsoft, we believe climate change is an urgent problem that demands a global response from all industries. We are committed to doing our part and have been taking steps to address and reduce our carbon footprint for nearly a decade. In 2009, Microsoft set its first carbon emissions target. In 2012, we became one of the first companies to put an internal global carbon fee in place, which enables us to operate 100 percent carbon neutral. Last year, we put in place targets to get more energy from renewable sources.

Today, we will take the next step in this journey by pledging to reduce our operational carbon emissions 75 percent by 2030, against a 2013 baseline. We’ll do this through continued progress against our carbon neutrality and renewable energy commitments, as well as investments in energy efficiency. This puts Microsoft on a path, as a company, to meet the goals set in the Paris climate agreement, which is a level of decarbonization that many scientists believe is necessary to keep global temperature increase below 2 degrees Celsius. We estimate this will help avoid more than 10 million metric tons of carbon emissions by 2030.

As we expand our global cloud infrastructure, we will increasingly turn to renewable energy because it is a clean power source and gives us better financial predictability. It’s good for the environment, our customers and our business. Our cloud-based programs to reduce resource consumption have already cut energy consumption at our main campus in Redmond, Washington by nearly 20 percent, reducing emissions and our power bill. The data we’ve collected on our energy consumption laid the groundwork for us to now buy our own clean energy at market rates, and we’ll soon be powering our Puget Sound campus with 100 percent carbon-free energy. Put simply, the environment and our business both benefit each time we’ve implemented sustainability targets and goals.

We’ve also seen that the private sector can be a catalyst for exponential change. This is particularly true for companies like ours. Artificial intelligence (AI) and the cloud are enabling companies and governments to make smarter, real-time decisions that lower emissions and reduce resource consumption in areas from buildings to transportation to manufacturing to agriculture to the production and distribution of electricity. We’re working not only to enable these transformations, but also to create and democratize new innovations through programs like AI for Earth that can help our customers adapt and thrive in a changing environment.

But even with our commitments within our operations and work with our customers, there’s still more to do.

As a global company, the changes we make in how we operate our business and the goals we set have a worldwide impact. It’s our hope that this pledge inspires others to join us in setting targets, and provides confidence to governments, companies and individuals that it’s possible for entities to help reach the goals set in the Paris climate agreement. By raising our ambitions and taking these actions, our goal is to help make the future more sustainable and beneficial to everyone.
