IDG Contributor Network: Can the US Senate secure the Internet Of Things?

As a free and open internet continues to come under assault by the FCC’s proposal to effectively end net neutrality, investors, programmers, and internet-users of all stripes have vociferously voiced their support of the Internet of Things and the open web that enables it. It appears those voices have been heard, as the US Senate may be taking steps to secure the Internet of Things’ future.So what exactly is the senate up to, and how might its actions impact the health of the Internet of Things? What are the specifics of the bill in question, and how might its text impact American’s everyday lives as they make use of the IoT?A hopeful bill A new bipartisan bill published Tuesday by Sen. Mark Warner and Sen. Cory Gardner, the Internet of Things Cybersecurity Improvement Act of 2017, hopes to beef up America’s internet security. The bill highlights the enormous complexity of the IoT and the huge benefits it provides to the American economy, but also notes the fragility and vulnerability of the system to outside attacks.To read this article in full or to leave a comment, please click here

IDG Contributor Network: 3 ways developers can improve IoT security on their devices

The much-beloved Internet of Things has come to fundamentally reshape how firms in virtually every industry operate. Nonetheless, the 21st century phenomenon that’s connected us all has some significant downsides, chief among them its vulnerability to outside attacks.As consumers and producers of IoT gadgets alike are finding their privacy and security increasingly jeopardized, many don’t know where to turn to for advice. By following these three simple tips, you can enhance your IoT security without creating a needless hassle or paying too much.Ensure your gadgets are patchable A staggeringly large amount of everyday IoT gadgets sold on the market come equipped with pre-prepared passwords which are essentially impossible to change, or, even worse, are just entirely impossible to patch. In the ever-changing digital world of the 21st century, IoT devices need to be patchable so they can be updated to resist the latest trends in malware attacks.To read this article in full or to leave a comment, please click here

Feedback: Network Automation 101

Some networking practitioners start their network automation journey with the Python or Ansible dilemma. Engineers and architects usually want to understand the bigger picture first, and figure out the potential showstoppers and roadblocks. One of them left this feedback on the Network Automation 101 webinar:

A must-have overview of fundamental Network Automation concepts. I wouldn't face an automation project without understanding these concepts first.

BGP : iBGP fully meshed solution : Confederations

Today I am going to talk about the one of the BGP article named as BGP Confederations. Now question is why we are using the BGP Confederations. If you guys ever configured the iBGP protocol you need to configure full meshed scenario in iBGP as per the rule of the policy.

With the full meshed network you will have to maintain all the links from all the routers to each other in the internal BGP network. So let us suppose you have 10 routers in your network and you want to configure iBGP network between them, so how many links you required to maintain the fully meshed network here. Well you need to have the 45 links between these 10 routers to establish the iBGP links between all of them.

You ever think that this may be of higher cost and ever router needs to have the information of the other routers in the network. Well to sort out iBGP full meshed network scenario we have two methods and these methods are Confederations and Route Reflectors.

In this article I am going to take the first method and the name is Confederations. In which I will explain how Confederations work and what are the basic Continue reading

5 host network configurations for MLAG

Host network configurations for MultiChassis Link Aggregation (MLAG, also referred to as dual-attach or ‘high availability’) can vary from host OS to host OS, even amongst Linux distributions. The most recommended and robust method is to use Link Aggregation Control Protocol (LACP), which is supported on most host operating systems natively. Host bonds or bonding refers to a variety of bonding methods, but for the purpose of this article it will refer to LACP bonds. The terms etherchannel, link aggregation group (LAG), NIC teaming, port-channel and bond can be used interchangeably to refer to LACP depending on the vendor’s nomenclature. For the sake of simplicity, we will just call it bonds or bonding. This post will take your through the steps for host network configurations for MLAG across five different operating systems.

Why LACP? LACP is a IEEE standard that has been available since 2000 known as 802.3ad. This makes a highly interoperable standards approach to bonding that can work across many network vendors and host operating systems. LACP is superior to static configuration (also referred to bond-mode ON) because there is a control protocol keeping the bond active. This means failover is predictable and automatic. This is also Continue reading

Data center provider Equinix bets big on fuel cells

Data center provider Equinix is making a big bet on fuel cells to power its facilities by installing natural gas-powered fuel cells at 12 of its U.S. data centers. It’s part of a push for the firm to be 100% reliant on renewable fuels, and it could set an example for other data centers in power management.Equinix uses fuel cells developed by Bloom Energy, a leader in the data center energy market that has been profiled by 60 Minutes and whose giant “batteries” are installed at data centers run by eBay, Apple, NTT, CenturyLink and Verizon.To read this article in full or to leave a comment, please click here
