10 outsourcing trends to watch in 2016

This year, we saw companies embrace increased standardization and cloud computing options of all flavors, use their leverage to renegotiate or rebid their deals, and settle into a best-of-breed approach to offshore outsourcing.So what will 2016 bring? Our experts expect a number of shifts in the industry—including a focus on hyper-speed deal making, the emergence of new multi-sourcing headaches and potential cures, increased man-machine collaboration, and significant expansion of the service provider universe.1. Security takes center stageSecurity is top of mind from the boardroom to the break room, and it will influence outsourcing strategy in 2016. Indeed, security risk is poised to increase as telematics and the Internet of Things (IoT) becomes more prevalent in consumer and commercial products, says Paul Roy, partner in the business and technology sourcing practice of Mayer Brown. “Increasing numbers of threat actors will use increasingly creative ways to exploit weaknesses, often with devastating effect. Regulators will exact increasingly large fines for poor security. Service providers have often been the weakest link in a company’s security and will need to find better ways to address that concern.”To read this article in full or to leave a comment, please click here

Running VLAN, VXLAN and GRE together using Neutron & Openstack

There are numerous blogs out there with step by step instructions to setup OVS networking for openstack neutron to run various types of networks. I came up with this post to best explain how everything works in the Neutron land and what a typical openstack deployment looks like. If you are looking for a more step-by-step procedure to set things up this post is a good place to start i.e. understanding the networking concepts and design behind running all the commands listed on other blogs.

A Neutron openstack deployment or any cloud environment these days typically consist of a Network Controller (SDN controller) and a cluster of compute hosts or servers. The type of networking you choose to connect all of these together is entirely upto you and I've seen various ways by which this can be done. There is no correct or right way of doing this. It's what works for you but if you don't really have anything already setup and are planning on starting afresh you could probably use this as a template to design your networking.


What you see above are three servers - one network node and two compute nodes.
First we'll go through Continue reading

Malware peddlers offered Raspberry Pi money to infect your micro-PC

The Raspberry Pi—the popular mini-PC that's about the size of credit card—is attracting attention from malware distributors. But not in the sense that you might think.Last Wednesday, the Raspberry Pi Foundation tweeted a screenshot of an email in which a company effectively asked to install malware onto users Raspberry Pis.+ ALSO ON NETWORK WORLD Ultimate guide to Raspberry Pi operating systems, part 2 +In the email, the company, whose name was redacted, offered the Foundation money in order to distribute an exe file on Raspberry Pi machines (never mind the fact that the Raspberry Pi doesn't run Windows). Installing the exe would place a shortcut icon on the desktop; if you open it, you'd be taken to the company's website. "Then this is our target," the email reads in part.To read this article in full or to leave a comment, please click here

The most innovative and damaging hacks of 2015

Not a week went by in 2015 without a major data breach, significant attack campaign, or serious vulnerability report. Many of the incidents were the result of disabled security controls, implementation errors, or other basic security mistakes, highlighting how far organizations have to go in nailing down IT security basics.But looking beyond the garden-variety attacks and vulnerabilities lends great insight into the future of malicious activity and how to defend against it. And 2015 had its share of intriguing invasions, each of which highlighted the modified techniques that lead to new forms of breaches or pinpoint areas in need of new defenses. The past year saw cyber criminals adopting innovative approaches and state-sponsored actors becoming bolder. Motivations shifted, with financial gain no longer the sole reason for launching an attack. Inflicting physical damage, stealing trade secrets, hacking as a form of protest -- 2015 was a year in which malicious activity served many ends.To read this article in full or to leave a comment, please click here

The next wave of cybercrime will come through your smart TV

Smart TVs are opening a new window of attack for cybercriminals, as the security defenses of the devices often lag far behind those of smartphones and desktop computers. Running mobile operating systems such as Android, smart TVs present a soft target due to how to manufacturers are emphasizing convenience for users over security, a trade-off that could have severe consequences. Smart TVs aren't just consumer items, either, as the devices are often used in  corporate board rooms. Sales of smart TVs are expected to grow more than 20 percent per year through 2019, according to Research and Markets. While attacks against smart TVs are not widespread yet, security experts say it is only a matter of time before cybercriminals take note of the weaknesses.To read this article in full or to leave a comment, please click here

Dual Core Network Design

Dual core design, also known as dual plane or disjoint plane topologies, refers to a highly redundant network chosen by companies whose main objective is to improve the resiliency of their network. Created using different data planes, dual core design is implemented by companies that receive the service from the different service providers. Put simply, […]

New Chinese law takes aim at encryption

A new law passed by China's Parliament on Sunday requires technology companies to assist the government in decrypting content, a provision that the country maintains is modeled after Western law. ISPs and telecommunication companies must provide technical assistance to the government, including decrypting communications, for terrorism-related investigations, according to Xinhua, China's official news agency. Xinhua quoted Li Shouwei, of the National People's Congress Standing Committee legislative affairs commission, as saying the law doesn't require technology companies to install "backdoors," the term for code that would give security agencies consistent, secret access to data, in software.To read this article in full or to leave a comment, please click here

Training the Next-Generation Network Engineer

The networking industry is at a crossroads. In the past few years, we’ve seen a flurry of activity in the world of software-defined networking (SDN), but this has mostly just resulted in a bunch of new products. I don’t feel that this has done nearly enough to improve network operations. In fact, this has in many ways resulted in more complexity.

What we desperately need more than shiny new products (hardware or software) is a better understanding of simple tools and open source software. We need to be willing to take more direct control over our infrastructure, instead of relying on a vendor and their support contracts to solve all our problems. While vendors should still serve a critical role in operating a network, I feel strongly that now more than ever, end-users have the power to really own their own management layer, and the roadmap for how their organizations offer network services to the teams that run (and in some cases develop) applications for the business.

To that end, I’ve been spending the past six months or so ramping up my own personal efforts at helping the network community as a whole to start this journey. These simple contributions Continue reading
