With this release, NSX-T 2.3 continues to enable VMware’s vision of delivering consistent, pervasive connectivity and intrinsic security for applications and data across any environment. These new advancements help customers implement a more secure, end-to-end software-based network architecture – a Virtual Cloud Network – that supports their multi-cloud enterprises and advanced security in new and compelling ways.
NSX-T Data Center 2.3 extends advanced multi-cloud networking and security capabilities to AWS, in addition to Microsoft Azure and on-premises environments, and adds support for bare metal hosts as well.
Here are a few highlighted features among what’s new in this release.
NSX-T Data Center 2.3 introduces support for bare metal hosts, in addition to hypervisor and container environments. This includes Linux-based workloads running on bare-metal servers, as well as containers running on bare-metal servers without a hypervisor. To support this new capability, NSX-T leverages the Open vSwitch, allowing any Linux host to be an NSX-T transport node.
Bare-Metal Server Support
This release introduces support for Bare-Metal native compute workloads running RHEL 7.4, 7.5, CentOS 7.4, and Ubuntu 16.0.4 operating systems that allows users to network Bare-Metal compute Continue reading
With the enormous attack surface of cloud providers like AWS, Azure, and GCP, why aren't there more security problems? Data breaches and cyber attacks occur daily. How do you explain the unreasonable effectiveness of cloud security?
Google has an ebook on their security approach; Microsoft has some web pages. Both are the equivalent of that person who is disgustingly healthy and you ask them how they do it and they say "I don't know. I just eat right, exercise, and get plenty of sleep." Not all that useful. Most of us want a hack, a trick to good health. Who wants to eat right?
I'm sure Amazon also eats right, exercises, and gets plenty of sleep (probably not the people who work there), but AWS also has a secret that when that disgustingly healthy person starts talking about at a party, you just can't help leaning in and listening.
What's the trick to 6-pack security? Proving systems correct. Does your datacenter do that? I didn't think so. AWS does.
Dr. Byron Cook gave an enthusiastic talk on Formal Reasoning about the Security of Amazon Web Service. He's clearly excited about finally applying his research in a Continue reading

McAfee says Presidents Trump and Obama have malware campaigns named after them. Tenable discloses a flaw that could affect hundreds of thousands of security cameras globally.
The coming end-of-support for Windows Server 2008 is the perfect opportunity for IT organizations to tap Docker Enterprise to modernize and secure legacy applications while saving millions in the process.
The coming end-of-support for Windows Server 2008 in January 2020 leaves IT organizations with a few viable options: migrate to a supported operating system (OS), rehost in Azure, or pay for an extended support contract (up to 75% of the license fee per year) to receive security updates beyond the cut-off date. The option of doing nothing (running applications on unsupported OS versions) is a non-starter for the vast majority of businesses, as this poses a significant security and compliance risk. We saw the impact of this last year when a massive ransomware attack that affected nearly 100 countries spread by targeting end-of-life and unpatched systems.
Upgrading will be no small feat as roughly 80% of all enterprise applications run on Windows Server. Of those applications, 70% still run on Windows Server 2008 or earlier versions*. Migrating all of these critical applications to a supported version of Windows Server is painful and costly, due to rigid legacy Continue reading
IT staffing budgets are shrinking and consequently many organizations are forgoing having strong engineering talent on staff. In this episode we explore the dynamics of staffing good engineers and whether or not it’s possible to remove that cost in modern networks.

Tune into Gabe Rivas’s most recent course release, Network Foundation Protection: Management Plane, the second in a series of eight CCNA security courses.
Network Foundation Protection is a security framework that provides with strategies to protect three functional areas of a device: Management Plane, Control Plane, and Data plane. In this Course we will focus on the management plane functionality and we will look at ways to protect and secure management access to network devices. We will compare the Pros and Cons of using an in-band vs an out-of-band management network and we will learn how to use network management protocols such as SNMP, NTP, SCP, RADIUS, TACACS+, Telnet, SSH, HTTP, and HTTPS to name a few. We will also learn the difference between the Cisco ACS and ISE servers and configure TACACS+ on ISE and an IOS device to provide with AAA for device administration. As a bonus, we will look at commonly used tools that can help you determine Cisco product vulnerabilities, best recommended software, and how to search bugs.
If this was a single course covering the entire CCNA Security blueprint, the pre-requisite would have been the CCENT Certification or equivalent knowledge. Since this is Continue reading
Last week, the Internet Society together with our Kyrgyz chapter and the wider local community held discussions about Internet connectivity in remote areas in Bishkek, Kyrgyzstan. Approximately 35% of the Kyrgyz population use the Internet (ITU data, 2017) and most users are located in cities and urban areas.
In cooperation with its Kyrgyz chapter, the Internet Society is piloting the community networks approach in the village of Suusamyr, located some 150 kilometers south of the capital city Bishkek. We had an opportunity to visit this village of about 4000 people, tucked away in a wide valley surrounded by high mountains. The economic activity revolves around farming, horse and cattle keeping, and tourism.
While the final phase of the Suusamyr community network is still under implementation, we can already draw some lessons learnt from the preparatory and testing phases.
Partnerships
As a starting point, the Internet Society Kyrgyz chapter consolidated a partnership with the government, Internet Service Providers (ISP), and the local community in Suusamyr. The Kyrgyz government saw the opportunity for local economic development. Two ISPs agreed to lease their existing backbone infrastructure to connect the last mile. And most importantly, the local community embraced this initiative with a Continue reading
Hot networks served chilled, DCNM style
When I started this blog for Data Center Interconnection purposes some time ago, I was not planning to talk about network management tools. Nevertheless, I recently tested DCNM 11 to deploy an end-to-end VXLAN EVPN Multi-site architecture, hence, I thought about sharing with you my recent experience with this software engine. What pushed me to publish this post is that I’ve been surprisingly impressed with how efficient and time-saving DCNM 11 is in deploying a complex VXLAN EVPN fabric-based infrastructure, including the multi-site interconnection, while greatly reducing the risk of human errors caused by several hundred required CLI commands. Hence, I sought to demonstrate the power of this fabric management tool using a little series of tiny videos, even though I’m usually not a fan of GUI tools.
To cut a long story short, if you are not familiar with DCNM (Data Center Network Manager), DCNM is a software management platform that can run from a vCenter VM, a KVM machine, or a Bare metal server. It focuses on Cisco Data Center infrastructure, supporting a large set of devices, services, and architecture solutions. It covers multiple types of Data Center Fabrics; from the Storage Continue reading
This article will talk about our approach to network security using technologies like RPKI to sign Internet routes and protect our users and customers from route hijacks and misconfigurations. We are proud to announce we have started deploying active filtering by using RPKI for routing decisions and signing our routes.
Back in April, articles including our blog post on BGP and route-leaks were reported in the news, highlighting how IP addresses can be redirected maliciously or by mistake. While enormous, the underlying routing infrastructure, the bedrock of the Internet, has remained mostly unsecured.
At Cloudflare, we decided to secure our part of the Internet by protecting our customers and everyone using our services including our recursive resolver 1.1.1.1.
A prefix is a range of IP addresses, for instance, 10.0.0.0/24, whose first address is 10.0.0.0 and the last one is 10.0.0.255. A computer or a server usually have one. A router creates a list of reachable prefixes called a routing table and uses this routing table to transport packets from a source to a destination.
On the Internet, network Continue reading
We have talked about the BGP Internet routing protocol before. We have talked about how we build a more resilient network and how we can see outages at a country-level via BGP. We have even talked about the network community that is vital to the operation of the global Internet.
Today we need to talk about why existing operational practices for BGP routing and filtering have to significantly improve in order to finally stop route leaks and hijacks; which are sadly pervasive in today’s Internet routing world. In fact, the subtle art of running a BGP network and the various tools (both online and within your a networks subsystems) that are vital to making the Internet routing world a safe and reliable place to operate need to improve.
Internet routing and BGP and security along with its operational expertise must improve globally.
Nothing specific triggered today’s writing except the fact that Cloudflare has decided that it's high-time we took a leadership role to finally secure BGP routing. We believe that each and every network needs to change its mindset towards BGP security both on a day-by-day and a long-term basis.
It's time to stop Continue reading
Network managers need to be open to an expanded partnership with the security group. A new EMA report finds such collaboration is already underway in many organizations.
Although this article mainly targets OpenVPN TAP driver installation issue, The problem is likely not limited to that specific driver.
You may want to continue reading and give the very easy solution at the end of the article a try.
Recently I had to install OpenVPN on a system running Windows XP (Don’t ask). The installation went smoothly up until TAP driver installation and then suddenly things went haywire:
The yellow marked status with the code of 28 in the device manager was not promising either:
In Windows XP, to install its inf file, TAP driver installation uses the built-in Windows Device Console (Devcon.exe). Pretty simple stuff, you just use devcon.exe with the install argument, supply the inf file and then provide the device’s Hardware ID.
This is the command being used to install each TAP NIC:
"C:\Program Files\TAP-Windows\bin\devcon.exe" install "C:\Program Files\TAP-Windows\driver\OemWin2k.inf" tap0901
Which gave a mundane error:
devcon.exe failed.
Devcon however, leaves a log file of its operation behind in %windir%\setupapi.log which included these lines:
#E122 Device install failed. Error 2: The system cannot find Continue reading
This is the third blog post in “thinking out loud while preparing Network Infrastructure as Code presentation for the network automation course” series. You might want to start with Network-Infrastructure-as-Code Is Nothing New and Adjusting System State blog posts.
As I described in the previous blog post, the hardest problem any infrastructure-as-code (IaC) tool must solve is “how to adjust current system state to desired state described in state definition file(s)”… preferably without restarting or rebuilding the system.
There are two approaches to adjusting system state:
