How to Build a Secure Network of Internet of Things (IoT) Devices

[fa icon="pencil'] Posted by Priyank Ghedia [fa icon="calendar'] April 10, 2018 [fa icon="tags'] Cisco, Networking, Data Security, Information Security, IoT

The “Internet of Things”, or IoT for short, is a buzzword you’ve probably heard many times before, but what does it really mean? Simply put, an IoT product is just a sensor with the ability to call home and execute functions that it’s designed for.

It’s become a hot topic in the last decade, but IoT has actually been around much longer than that even. One of the first mainstream consumer-facing applications was implemented in 1982. It was a smart Coca-Cola vending machine that reported the status of the vending machine so a technician could be sent to refill the cans when it was running low. If we fast forward to 2020, researchers predict 30-50 BILLION devices will be connected. By comparison, that’s 4-7x the world’s population.

Share Only One Application Not Entire Desktop in WebEx

[fa icon="pencil'] Posted by Lewan Solutions [fa icon="calendar'] March 31, 2016 [fa icon="tags'] Cisco, How To Guide

Screen sharing in Cisco WebEx can be a great tool for presenting to multiple viewers. But what if you only want to share one application and not your entire desktop with your audience?

You might have other windows open that contain proprietary information like Jabber chatter or email, or just additional windows that aren't pertinent.

This how-to post will guide you through a worry-free way to present only what you want without the risk of showing more than intended to viewers.

Cisco UC 10.X - Adding Prefixes to Call History for Ease to Users

[fa icon="pencil'] Posted by Amy Marx [fa icon="calendar'] August 17, 2015 [fa icon="tags'] Cisco, Unified Communication & Collaboration

Most Unified Communication deployments today require end users to dial an 8 or 9 prior to making outbound calls. Meaning users are asked to use the ‘Edit Dial’ soft key when trying to dial back a number in their call history.

Yes, there are methods available to modify inbound calls by creating route patterns, translation patterns, calling party transformation patterns, updating device pools and editing gateway configurations. These processes can be cumbersome though as you must come up with one or more wildcard to match every possible number which might end up as a missed call.

The good news is that there is an easier configuration option that will save yourself on setup time AND save your end users from having to perform this bothersome step.

What is an IOP and why do I care...disk math, and does it matter?

[fa icon="pencil'] Posted by Lewan Solutions [fa icon="calendar'] June 14, 2015 [fa icon="tags'] VMware, Data Storage, NetApp, Cisco, Disk Performance, Nimble Storage

I'll start by answering the title question first. IOP is an acronym standing for Input Output Operation. It does seem like it should be IOO, but that's just not the way it worked out.

A related fact to note: we generally talk either about total IOPs for a given task, or we talk about a rate - IOPs per Second typically, noted as IOPS with a capital "S". And with that, the Wikipedia portion of today's discussion is complete. Let's move on to why we care about IOPs...
