Worth Reading: DNS resolution to protect networks

The vast majority of DNS Resolvers perform its one core function – taking a unique domain name and resolved queries for these names into IPv4/IPv6 addresses for the purpose of locating computer services and devices worldwide. This is why DNS is Internet critical. Every device is dependent on a DNS Resolver for normal Internet functioning – creating a critical dependency and choke point. —Barry Greene @ Senki

IDG Contributor Network: Leveraging a hybrid cloud model to cope with data growth

In “What the storage industry’s inevitable transition to the cloud means for your business,” I cited the explosive growth of data as one of the primary reasons for a shift in storage architectures from local hardware to the cloud.Let’s take a closer look at this phenomenon and how it impacts your approach to storage, as well as what architecture is the right one for your current and future needs.And what a phenomenon it is! IDC and EMC project that data will grow to 40 zettabytes by 2020, resulting in a 50-fold growth from the beginning of 2010. And forget about the importance of data simply for your business. In a recent white paper for storage firm Seagate, research firm IDC estimates that by 2025, nearly 20 percent of the data in existence will be critical to our everyday lives, with almost 10 percent of that being “hypercritical.”To read this article in full, please click here

Small wake-up receivers could extend IoT sensor life

One of the potential hindrances to ubiquitous Internet of Things (IoT) take-up is related to how one should power the possibly billions of tiny sensors promised over time. Can one expect a homeowner to change out a hundred or so coin batteries every few years in, say, a networked system, for example? That could get old fast.Also on Network World: Testing RFID IoT devices for enterprise deployment The same problem arises at an industrial level. Changing out sensor batteries in a remote installation is equally difficult to achieve, although for different reasons — you need to transport expensive people there to do it, for one thing.To read this article in full, please click here

What is IPv6, and why aren’t we there yet?

For the most part the dire warnings about running out of internet addresses have ceased because, slowly but surely, migration from the world of Internet Protocol Version 4 (IPv4) to IPv6 has begun, and software is in place to prevent the address apocalypse that many were predicting.But before we see where are and where we’re going with IPv6, let’s go back to the early days of internet addressing.+Related: IPv6 deployment guide; How to plan your migration to IPv6+To read this article in full, please click here

How Self-Sufficient Do You Want to Be?

The first car I got decades ago was a simple mechanical beast – you’d push something, and a cable would make sure something else moved somewhere. I could also fix 80% of the problems, and people who were willing to change spark plugs and similar stuff could get to 90+%.

Today the cars are distributed computer systems that nobody can fix once they get a quirk that is not discoverable with level-1 diagnostic tools.

CCIE Collaboration Blueprint Changes and Collab. 2.0 Video Release Dates: As Explained by Rohit Pardasani

Cisco has announced that the CCIE Collaboration Lab blue print is changing from version 1.0 to version 2.0. The new blueprint goes live on July 23, 2018.
As expected, the lab will not have any physical devices, everything will be virtualized. The phones (8845), being the only physical devices, will be remotely controlled, students will not have them on their desk anymore.
Besides the phones, students will also have remote control of Spark, Jabber and the Cisco Meeting App.

Cisco also announced several new products and solutions, such as the Cisco Expressway Series, Cisco Meeting Server, Cisco Spark Hybrid Services, Cisco Unified Communications Mobile and Remote Access, and Cisco Cloud Services Router (CSR) 1000V. New topics such as APIs have also been added to ensure that CCIE Collaboration certified engineers have the knowledge and skills needed to satisfy dynamic requirements in customers’ collaboration environments today.

The traditional UC products are using version 12 (UCM/IMP/Unity Connection) and 11.6 in the case of CCX. All CCIE Collaboration v2.0 lab exam candidates will be provided a headset for questions that require audio verifications.

The new lab exam curriculum comprises seven domains. The new segmentation into these seven domains improves Continue reading

Intel launches new Xeon processor aimed at edge computing

Intel has launched its brand-new lineup of Xeon processors designed specifically for edge computing needs, where space, heat, and power are all of greater concern than in a traditional data center design.The Xeon D-2100 processors are the successor to the 1000-D series that Intel introduced last year. They are high-powered SoCs with anywhere from four to 18 Skylake-generation cores and sport the full range of Skylake features, including VT-X/VT-d for virtualization, RAS features and the entire TXT, AVX-512, TSX Instruction sets.Also read: What is edge computing and how it’s changing the network The platform supports up to 512 GB of memory, up to 32 PCI Express 3.0 lanes and up to 20 Flexible High Speed I/O. TDP ranges from 60 to 100 watts, slightly lower than the traditional Xeon design. All told, there are six processors in the Xeon D-2100 family, ranging from four cores to 18 and from 2.3Ghz to 2.8Ghz in speed.To read this article in full, please click here

Workshop on Binary Analysis Research (BAR) 2018 at NDSS on 18 February

Binary analysis refers to the process where human analysts and/or automated systems scrutinize the underlying code in software to discover, exploit, and defend against malice and vulnerabilities, oftentimes without access to source code. Through protecting legacy software deployed in all types of devices and platforms in the modern world, binary analysis techniques are becoming more and more critical in making our everyday life and our society more secure.

A Workshop on Binary Analysis Research (BAR) will be co-located with the Network and Distributed System Security Symposium (NDSS), and held in San Diego, CA, USA, on February 18, 2018.

The Workshop aims to provide an interaction point for researchers doing work in binary program analysis, with half of the workshop dedicated to traditional paper sessions and the other half to a roundtable discussion among researchers, implementers, and end-users of binary analysis techniques. BAR has attracted attention of many researchers, especially tool and framework authors, who actively work to create cutting-edge techniques and build powerful tools. Here we are happy to announce that eight high-quality academic papers have been accepted to appear in the paper sessions of the workshop, with presenters from both academia and industry. Researchers and authors of several Continue reading

Happy Valentine’s Day! Modernized infrastructure that I love

Today is Valentine’s Day, and that means showing appreciation to the people you love. I love my kids; my cats; my new puppy, Bodhi; and most of all my wonderful and amazing wife, Christine. She’s a kind, warm and loving person who has been fighting a rare illness called CVID for the past few years and still keeps a smile on her face and stops to smell the roses — something I’m not very good at.I would also like to use this Valentine’s Day to show appreciation for cool infrastructure innovation because the new stuff is becoming super important.To read this article in full, please click here
