IoT can learn from smartphone security

The massive growth of Internet of Things (IoT) devices over the next one to three years should give us pause. As companies rush to get to market first, are we seeing a “dumbing down” of basic device principals that we have been working with for years, particularly enhanced security and privacy. With so many distinct applications, device scope and diversity represent a unique security challenge that so far has not been met.I estimate that 85 percent or more of current IoT devices deployed in the real world do not have adequate security installed, and it’s likely that the vast majority of those will never be upgraded (or are not even capable of being upgraded). That means not only do current devices being installed pose a risk, but over the next one to two years, the vast majority of devices that will be deployed also pose a risk.To read this article in full or to leave a comment, please click here

Making a Clickable HTML Network Diagram using OmniGraffle

As a Mac user, I have to give my diagramming love to OmniGraffle and I try not to envy the Visio users too much. I maintain that Graffle diagrams subjectively look nicer than Visio, but in terms of features, Visio wins the day. Despite that, sometimes poor old Graffle does so something helpful and in this case, it’s being able to export a diagram as an image with an HTML image map.

The Plan For A Web-Based Network Diagram

My plan was to create a web-based network diagram for my home network where I could click on any device on the diagram and be connected to it using the appropriate protocol handler (e.g. SSH or HTTPS). This hypothetical page would not serve as a diagram of the network, but might also provide useful information for my long-suffering, geek wife, who tells me with despair in her eyes that she has no idea what the network looks like any more after I’ve messed around with it so much. She has a point. After considering making something in HTML, I realized that OmniGraffle would do the hard work for me, and it would be much easier to update later, too.

Apstra intent-based networking bridges the physical, virtual

Intent-based systems have been all the rage since Cisco announced its “Network Intuitive” solution earlier this year. For Cisco customers, its solution is certainly interesting. But what about businesses that want an alternative to Cisco? Or companies that want to run a multi-vendor environment?Over a year before Cisco’s launch, a start-up called Apstra shipped the closed-loop, intent-based solution. It was designed to be multi-vendor in nature with support for Cisco but also Arista, Juniper, HP and others, including white box. Apstra operates as an overlay to networks built on any of the leading vendors to deliver intent-based networking in heterogeneous environments.To read this article in full or to leave a comment, please click here

Set up a dedicated virtualization server on Packet.net

Packet is a hardware-as-a-service vendor that provides dedicated servers on demand at very low cost. For me and my readers, Packet offers a solution to the problem of using cloud services to run complex network emulation scenarios that require hardware-level support for virtualization. Packet users may access powerful servers that empower them to perform activities they could not run on a normal personal computer.

In this post, I will describe the procedure to set up an on-demand bare metal server and to create and maintain persistent data storage for applications. I will describe a generic procedure that can be applied to any application and that works for users who access Packet services from a laptop computer running any of the common operating systems: Windows, Mac, and Linux. In a future post, I will describe how I run network emulation scenarios on a Packet server.

Time to rethink how much customer data you store

Does the company you work for (or own) retain data on customers? Odds are pretty high that it does, at least in some form (often fairly extensively). It's often attractive to do so for both marketing and functionality purposes.But here's the thing, storing that data is probably a bad business decision. One that could cost your business a huge amount of money and, even worse, potential loss of trust by your most valuable customers.Storage costs  Just from the IT infrastructure point of view: As your business grows and the amount of data you store on each customer slowly expands (it always does), your cost for storing that data also grows. Rather quickly. Even if your data center is already well equipped, this is a not-insignificant recurring expense (failing drives, energy costs, other equipment needs, etc.).To read this article in full or to leave a comment, please click here

Update for the Free Network Engineers Group

A while ago, I created a slack group for the network engineers. Some of you might be a part of the group and have been enjoying, learning, discussing the networking topics, real life deployments, for a while.   I wanted to say that, I started to extend the group. It started initially for the Telco, […]

Cisco 6K Switch Supervisor Engines ( SUP 6T Vs SUP 2T)

I have been asked many times from many of the followers of the blogs about the SUP engines in Cisco catalyst 6k Series product mainly in Cisco 6500 Switches. Well first of all i would like to inform you that Cisco already announce Cisco 6500 chassis end of sale and also the previous SUP engines SUP-720 already end of life announcements.

As the question is related to Cisco 6500 Chassis only and the question is which chassis in Cisco 6500 Chassis supports SUP 2T and SUP 6T supervisor engines ?
Well the answer is SUP 2T and SUP 6T supported in the E-series 6500 chassis only. So if I am talking about the E-Series Chassis they are

  • Cisco Catalyst 6503-E 
  • Cisco Catalyst 6504-E
  • Cisco Catalyst 6506-E
  • Cisco Catalyst 6509-E
  • Cisco Catalyst 6509-V-E 
  • Cisco Catalyst 6513-E 

What are the capabilities of Cisco SUP 2T supervisor engines ?
Supervisor Engine 2T is designed to deliver higher performance, better scalability, and enhanced hardware enabled features. It integrates a high-performance 2-terabit (Tb) crossbar switch fabric that enables 80-Gbps switching capacity per slot on all Cisco Catalyst 6500 Series Switches.

IDG Contributor Network: How will the cloud be able to handle the emergence of IoT

Cloud computing and the Internet of Things (IoT) have spent the last several years in a sort of maximum-acceleration race where they’ve lapped the other players several times over and have only one another to measure against.IOT Expansion and Cloud Capacity Neither is slowing down, particularly the IoT. According to analysis firm Gartner, the number of IoT devices will hit 20.8 billion by 2020. The world population is expected to reach 8 billion in 2020, meaning there will be 2.5 IoT devices per person on the entire planet. In 2016, the IoT was growing at the rate of 5.5 million new things getting connected every day.To read this article in full or to leave a comment, please click here

WHOIS going to be at the Grace Hopper Celebration?

Ubuntu us are doing the round trip! It’s time to live - WAN you arrive at GHC, come meet us and say HELO (we love GNU faces, we’ll be very api to meet you). When you’re exhausted like IPv4, git over to the Cloudflare corner to reboot –– we’ll have chargers and Wi-Fi (it’s not a SYN to REST). R booth can be your ESC. Then Thursday morning we’re hosting a breakfast bash with Zendesk –– it will be quite the Assembly, you should definitely Go, compile a bowl of serial, drink a bit of CIDR or a cup of tee.

I’m also speaking at 1:30PM on Wednesday in OCCC W414 hashing out encryption and updates for IoT –– DES should be a fun session.

ACK! I did NAT tell you how to find us. Check for sum women in capes a few hops away from the booths with the lava LAMP stack. I'm the one with cURLs.

In D air! Excited to LANd. C you soon.

Why submarine cable , why not satellite ?

Why submarine/subsea cables rather than satellite. Story between my friend who is from finance background and myself.     Today, one of my friends who is totally foreigner to our industry,  visited me at home. It was a family dinner actually and as I said, He is not a network engineer but just a curios […]
