IDG Contributor Network: How IoT helps transplant surgeons track organ shipments

Transplanting organs is a matter of life and death. That’s why a donated organ has to be transported quickly and safely.There are more than 120,000 people on the United Network For Organ Sharing (UNOS) National Waiting List. Some patients have to wait up to five years for an organ donation. With so much at stake, how do you make sure a donated organ is transported safely to the recipient?Organ donation process The demand for donated organs greatly exceeds the supply, so patients are carefully screened before being added to the Organ Waiting List. The Health Resources & Services Administration (HRSA) defines the policies to be followed by the Organ Procurement and Transplantation Network (OPTN). Here is a simplified version of the protocol used to allocate donated organs:To read this article in full or to leave a comment, please click here

A Thirst For Petabyte Scale All-Flash Arrays

Some technology trends get their start among enterprises, some from hyperscalers or HPC organizations. With flash storage, it was small businesses and hyperscalers who, for their own reasons, got the market growing, drawing in engineering talent and venture capital to give us the plethora of options available on the market today. Now, the big customers are ready to take the plunge.

It is no coincidence, then, that Pure Storage has architected systems that scale to multiple petabytes of capacity to meet their needs. Large enterprises with pressing demands for scaling in terms of both performance and capacity need a different …

EVPN – the basics

A great EVPN overview and detailed walkthrough from a colleague of mine… Nice and clear.

PACKETS AND STUFF

So I decided to take a deep dive into eVPN, I’ll mostly be looking into VLAN-aware bundling, as per RFC 7432 – and mostly because I think this will fit more closely, with the types of deployments most of the customers are used to – good old IRB interfaces and bridge-tables!

As everyone knows, VPLS has been available for many years now and it’s pretty widely deployed, most of the customers I see have some flavour of VPLS configured on their networks and use it to good effect – so why eVPN? what’s the point in introducing a new technology if the current one appears to work fine.

The reality is that multipoint layer-2 VPNs (VPLS) were never quite as polished as layer-3 VPNs, when layer-3 VPNs were first invented they became, and still are the in many cases the “go to” technology for layer-3 connectivity across MPLS networks, and…

Jinja2 and… Powershell? Automation(ish) Microsoft DHCP

Most of us have home labs, right?

I’m in the middle of doing some zero touch provisioning testing, and I had the need to create a bunch of DHCP scopes and reservations, some with scope specific options, and some with client specific options. As often as I’ve had to create a Microsoft DHCP server in the lab and set up some custom scopes, I decided I was going to figure out how to automate this as much as I could with a little effort as possible.

After taking a quick look around for a python library to help me out, python being my weapon of choice, I realized that I was going to have to get into some Powershell scripting. I’ve dabbled before, but I’ve never really take the time to learn much about Powershell control structures ( loops, conditionals, pipes, etc…).  I really didn’t want to spend the time getting up to speed on a new language, so I instead decided I was going to use the python skills I had to auto generate the scripts using a little jinja2 and some google-technician skills.

Figuring out the Powershell Syntax

This was the easy part actually, Microsoft has some pretty Continue reading

Forensics Challenge for CSIRT Team – Part 1 Assignment

I have created a virtual machine that you can use to test your forensics analysis skills. Please, download the VM, solve an assignment below and share solutions with us.

1. Assignment
Your are a member of elite CSIRT team which is responsible for dealing with computer security incidents in your jurisdiction. You are asked to investigate a server that was previously administered by disgruntled administrator Mr. Abdullah Khan who was fired up. Although login credentials for server were changed after Khan's sacking from the company, it is believed he might insert malicious software into server before change of credentials. Your task is to ensure that a sever does not contain any malicious software and user data stored on the server are not compromised. You also need to prove your professional forensic skills and analyze a suspicious file in case you find it on the server. Based on your investigation you should find out how malware work and create detailed report for your boss.

The server is running Ubuntu 16.04.1 and it is primary used as a file server with configured SSH access. Unfortunately the backup of user files is damaged and cannot be used in case of data are lost during your investigation. The login/password is Continue reading

On the ‘Net: Big thinkers leave Cisco

The industry is reeling from Monday’s report that four of Cisco’s best-known executives are leaving the company. An internal memo from Cisco CEO Chuck Robbins, first reported by the Wall Street Journal, announced the resignations of Mario Mazzola, Prem Jain, Luca Cafiero and Soni Jiandani, effective June 17. The four formed a team that many referred to as MPLS — letters that represent the initials of their first names. -Channel Partners

On the ‘Net: You keep using that SDN word…

Software Defined Networks (SDNs), are everywhere, and everyone is either building one, selling one, or using one. Everyone, that is, except—probably—you. Don’t feel too bad if you’re feeling left out, because it’s hard to know, precisely, what you’re actually being left out of. After all, can you actually define what an SDN is? -ECI

Big data paper shows stock market trades behave like light bulbs

In the stock market, electronic trading (AKA “etrading”) originally started so people could buy and sell stocks and other financial instruments more easily. No more hanging out on the floor of a stock exchange or calling your orders into your broker; you could do it all from your desktop. This was good because it made markets more accessible and reduced costs.Then, in the 1980’s, because the electronic trading platforms had application programming interfaces to allow new client-side interfaces to be developed, the inevitable happened, the next generation of electronic trading appeared. Algorithmic trading (AKA “algo trading” or “black box trading”) removed humans from the equation and exploded as the latest, greatest stock market money-making strategy. To read this article in full or to leave a comment, please click here
