Citigroup is cutting costs by making storage simpler

Citigroup is using software-defined storage to build an infrastructure that could last 25 years – while generations of hardware come and go.The financial services company needs to transform its storage architecture to deal with growing and changing demands, says Dan Maslowski, global head of storage and engineered systems. By simplifying its architecture, Citigroup expects to slash its operational expenses, which make up most of its storage costs.Citigroup’s need for storage is growing so fast that if costs don’t go down, the company’s spending on storage might eat up its entire IT budget in a few years, Maslowski told an audience at the Storage Developer Conference in Santa Clara, California, on Tuesday.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Is today’s network cost structure indicative of the future?

I’ve been a fan of software-defined networking (SDN) since my first conversation about software-based firewalls for an application deployment in 2004. Our goal was to leverage the concepts of grid computing to grow and shrink the web and application server environments in response to load, and we got the idea to throw the firewall into the mix. What made our approach possible was the ocean’s depth of software development knowledge on our team tempered by a puddle’s depth knowledge of networking.+ Also on Network World: Survey shows growing interest in SDN, where and how companies might deploy the tech +To read this article in full or to leave a comment, please click here

Worth Reading: Cryptocurrency mining malware infecting NAS’

A malware variant named Mal/Miner-C (also known as PhotoMiner) is infecting Internet-exposed Seagate Central Network Attached Storage (NAS) devices and using them to infect connected computers to mine for the Monero cryptocurrency. Miner-C, or PhotoMiner, appeared at the start of June 2016, when a report revealed how this malware was targeting FTP servers and spreading on its own to new machines thanks to worm-like features that attempted to brute-force other FTP servers using a list of default credentials. —Softpedia

Yahoo reportedly to confirm massive data breach

Following reports that Yahoo will confirm a data breach that affects hundreds of millions of accounts, some users reported Thursday on Twitter and elsewhere that they were prompted to change their email password when trying to log in.Yahoo launched an investigation into a possible breach in early August after someone offered to sell a data dump of over 200 million Yahoo accounts on an underground market, including usernames, easy-to-crack password hashes, dates of birth and backup email addresses.The company has since determined that the breach is real and that it's even worse than initially believed, news website Recode reported Thursday, citing unnamed sources familiar with the investigation.To read this article in full or to leave a comment, please click here

Keeping up with incident response

A fire department in a large city certainly has a difficult job, but its mission is fairly straightforward. When a fire is detected, the fire department dispatches an appropriately sized staff to assess, contain and put out the fire, clean up, investigate what happened, and prepare themselves for the next blaze.Yup, it's a pretty simple process when a manageable number of fires are burning. But what would happen if there were hundreds or thousands of simultaneous infernos?My guess is that a senior fire chief (and perhaps other participants from local government and law enforcement) would have to make decisions on which blazes to resource and which to ignore. These decisions would certainly be based upon information analysis and best practices, but there is still some risk that the disregarded fires would end up being far worse than expected, turn into disasters, and call into question the judgement of all involved.To read this article in full or to leave a comment, please click here

Fixing the mixed content problem with Automatic HTTPS Rewrites

CloudFlare aims to put an end to the unencrypted Internet. But the web has a chicken and egg problem moving to HTTPS.

Long ago it was difficult, expensive, and slow to set up an HTTPS capable web site. Then along came services like CloudFlare’s Universal SSL that made switching from http:// to https:// as easy as clicking a button. With one click a site was served over HTTPS with a freshly minted, free SSL certificate.

Boom.

Suddenly, the website is available over HTTPS, and, even better, the website gets faster because it can take advantage of the latest web protocol HTTP/2.

Unfortunately, the story doesn’t end there. Many otherwise secure sites suffer from the problem of mixed content. And mixed content means the green padlock icon will not be displayed for an https:// site because, in fact, it’s not truly secure.

Here’s the problem: if an https:// website includes any content from a site (even its own) served over http:// the green padlock can’t be displayed. That’s because resources like images, JavaScript, audio, video etc. included over http:// open up a security hole into the secure web site. A backdoor to trouble.

Web browsers have known this was a problem Continue reading

IDG Contributor Network: AT&T’s AirGig shows wireless internet over power lines is possible

High-speed wireless internet could soon be delivered over power lines, according to a major mobile network operator that announced positive test results of a proposed system.AT&T says its project, called AirGig, will deliver multiple gigabit-speed wireless internet by creating broadband signals that will emanate from the power lines crossing the country and beyond.The company says it won’t actually connect its equipment directly to the powerline cables but will simply use the wires as way to send modulated radio signals to individuals’ homes, smartphones, tablets and so on. The equipment sits atop the utility poles and uses the existing wires for transmitting and receiving.To read this article in full or to leave a comment, please click here

Google’s Allo is an early personal assistant, not a late-to-market messaging app

Allo is a child that Google just sent to school to become your personal assistant. The first release looks like a messenger app because it is a common user interface (UI) that almost all smartphone users know, and it is conversational. Like a child learns to speak through conversation with adults, Allo will learn to be a personal assistant through quadrillions of messaging conversations if it succeeds as the next big platform.Google Now and Apple’s Siri are rudimentary compared to the personal assistant that Google Allo could become. Google Now’s and Siri’s voice to text is pretty accurate, but the user is limited to a fixed set of commands, navigate, play music, search, etc.To read this article in full or to leave a comment, please click here
