Devices with Qualcomm modems safe from critical ASN.1 telecom flaw

Despite initial concerns, smartphones equipped with Qualcomm modems are not vulnerable to a recently announced vulnerability that could potentially allow attackers to take over cellular network gear and consumer mobile devices. The vulnerability was discovered in ASN1C, a popular compiler that produces C code for parsing ASN.1 encoded data. Abstract Syntax Notation One (ASN.1) is a standard for representing, encoding, transmitting, and decoding data in telecommunications and computer networking. Many devices, from mobile phones to switching equipment inside cellular infrastructure parse ASN.1 data and do so using programs that were created by compilers such as ASN1C, which is developed by U.S.-based Objective Systems.To read this article in full or to leave a comment, please click here

IDG Contributor Network: OK — What is this Nano Server in Windows Server 2016?

Nano is a prefix that means small, really small. Maybe even microscopic small. So that means we know right away Nano Server is very small version of Windows Server 2016. But wait, didn’t we already have that with Windows Server 2012 Core. Nano Server is a nice GUI-less version of the server technology.+ Also on Network World: Is Windows Nano Server a data center game-changer? +Nano makes Server Core look bloated and massive. Don’t believe me? Let’s looks at some numbers.The full GUI Server version of Windows Server has required the following:To read this article in full or to leave a comment, please click here

Five years until transistors stop shrinking, predicts last Moore’s Law roadmap

Moore’s Law, which says the number of transistors within an integrated circuit will double every two years, had a good long run but its end may be near – very near – potentially a mere five years away. By 2021, even if chip makers could further shrink and add more transistors, the high cost of manufacturing would make it financially impractical.That’s not the only problem, according to the last installment of the International Technology Roadmap for Semiconductors 2.0 (pdf).By 2020 to 2025, it will be “practically impossible” to reduce device dimensions. While one solution is to stack the transistors, it can’t get so hot that it burns up either.To read this article in full or to leave a comment, please click here

Operationalizing Micro-segmentation – NSX Securing “Anywhere” – Part III

hand-813525_1280Welcome to part 3 of the Micro-Segmentation Defined – NSX Securing “Anywhere” blog series. This installment covers how to operationalize NSX Micro-Segmentation. Be sure to check out Part 1 on the definition of micro-segmentation and Part 2 on securing physical workloads with NSX.

This blog covers the following topics:

  1. Micro-segmentation design patterns
  2. Determining appropriate security groups and policies
  3. Deploying micro-segmentation
  4. Application lifecycle management with vRealize Automation and NSX
  5. Day 2 operations for micro-segmentation

Micro-segmentation design patterns

Micro-segmentation can be implemented based on various design patterns reflecting specific requirements.  The NSX Distributed Firewall (DFW) can be used to provide controlled communication between workloads independent of their network connectivity. These workloads can, for example, all connect to a single VLAN. Distributed logical switches and routers can be leveraged to provide isolation or segmentation between different environments or application tiers, regardless of the underlying physical network, as well as many other benefits.  Furthermore, the NSX Edge Service Gateway (ESG) can provide additional functionality such as NAT or load balancing and the NSX Service Insertion framework enables partner services such as L7 firewalling, agent-less anti-virus or IPS/IDS applied to workloads that need additional security controls.

Microservices Gone Wild – Tech Dive Part 3

Tech Dive - Microservices

In this third post in the series about microservices, I’ll finish building my main application so that I can demonstrate a microservices-based application in action, albeit for a very basic set of functions. This post may be a little go-heavy in places, but bear with it and I’ll get to the demo soon enough. It doesn’t really matter what language is being used; I just used go because it’s good practice for me.

Building The Main Application

As a reminder, the main application will need to accept two numbers on the command line then will need to multiply the two numbers and then square that product. The two mathematical functions (multiply and square) are now offered via a REST API, and each one has its own separate Docker container with apache/PHP to service those requests.

I have created hostnames for the two microservice containers (DNS is the only smart way to address a microservice, after all) and they are accessed as:

  • multiply.userv.myapp:5001
  • square.userv.myapp:5002

The API path is /api/ followed by the name of the function, multiply or square, and the values to feed to the function are supplied as the query string. Most APIs tend Continue reading

Worth Reading: How Facebook makes you miss out on life

People spend nearly an hour on Facebook every day. Maybe that doesn’t automatically sound impressive. But when you parse the numbers, the significance becomes clear: as James B. Stewart wrote for the New York Times, “That’s more than any other leisure activity surveyed by the Bureau of Labor Statistics, with the exception of watching television programs and movies (an average per day of 2.8 hours). It’s more time than people spend reading (19 minutes); participating in sports or exercise (17 minutes); or social events (four minutes). It’s almost as much time as people spend eating and drinking (1.07 hours).” —The Federalist

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 …
