IT embraces bring your own device in corporate deployment, despite risks

Publié: mai 18, 2012, 11:41pm CEST par Ed Oswald

While the bring-your-own-device phenomenon in IT presents a fair amount of risk to enterprise security, most companies are warming up to the idea anyway. A Cisco-sponsored survey of 600 IT and business leaders found that 95 percent of their companies allow employee-owned devices on the corporate network.

Of all companies surveyed, 36 percent support all BYOD devices, while 48 percent support a select list of devices. An additional 11 percent tolerate employee-owned devices on enterprise networks, but will offer no IT support.

The overwhelming number of corporations giving some type of support to BYOD is due to a large majority of IT executives themselves seeing the initiative as positive to their companies. Cisco says 76 percent of respondents called BYOD either somewhat or extremely positive, citing higher employee job satisfaction and increased productivity as reasons for their support. The benefits outweigh the risks, the data suggests, and it's better to keep your employees happy.

While employees may appreciate device choice, there's a much more personal reason behind the push for BYOD. Employees cite personal freedom as a major reason for wanting their own devices in the workplace. Corporate-owned hardware typically comes with usage policies that prevents personal use. That means checking Facebook or instant messaging is a no-no. Cisco says it found that 69 percent of BYOD users were using unapproved applications on these devices.

Simply put? It's much more difficult to track what your employees are doing when they're using their own devices. BYOD gives the employee the freedom to do as they wish.

This personal component seems to really be driving the BYOD phenomenon, but the need for mobile connectivity is also a factor. Cisco found that four in five white-collar employees use a mobile device in the course of their workday, with 65 percent of all white-collar workers requiring mobile connectivity in order to perform their jobs.

"As the number of devices being brought into work increases, organizations need a comprehensive mobility strategy", Cisco chief technology officer Padmasree Warrior says. Undoubtedly, this strategy needs to include some type of security component, as respondents listed security concerns as a top challenge in dealing with BYOD.

iPhone meets its match

Publié: mai 18, 2012, 8:10pm CEST par Joe Wilcox

Finally, initial sales of another smartphone smoke iPhone -- that is if leaked numbers prove true. Samsung Galaxy S III goes on sale in 11 days, but preorders reportedly already top 9 million. By comparison, the much-lauded iPhone 4S sold 4 million units, including preorders, during its first three days of availability. At this pace, Galaxy S III is poised to be the biggest smartphone launch to date.

Samsung announced the smartphone on May 3, when I asked: "Is iPhone 4S obsolete?" Surely someone thinks so, and their answer should chill the hearts of Apple apologists and investors. Samsung, not Apple, is the rising star in the cloud-connected device firmament. Perhaps iPhone 5 will change matters. But for now, Samsung, propelled by the Galaxy S brand, broad channel distribution and smart software innovation, is brightest star.

Samsung Sales eclipse Apple's

Many of you are among those early buyers. Four days ago I asked: "Will you buy Samsung Galaxy S III?" Among the 1,195 responses so far, 18.16 percent have preordered or plan to. Another 41.59 percent plan to buy within 3 months. Less than one-quarter, 24.02 percent, won't buy the S3. Granted, the responses represent more of a gadget audience and are unqualified -- meaning I don't know who you are.

But the numbers jive with other trends. Based on sales to end users, rather than shipments into the channel, Samsung snatched overall phone leadership from Nokia and smartphone top-ranking from Apple during first quarter. Samsung sold 38 million smartphones -- 86.6 million for all handsets -- to Apple's 35.1 million, according to Gartner. Something else: Samsung accounted for 40 percent of Android sales. That's right, four out of every 10 recent Android smartphone buyers got a Samsung.

Several factors work in Samsung's favor -- and that of Galaxy S III. While the handset will initially launch in Europe, Samsung plans to rapidly reach 296 carriers in 145 countries. Apple offers iPhone 4S through 230 carriers in 100 countries. Samsung marketing, particularly its make-fun-of iPhone users campaign, is effective. For example, the first two "Next Big Thing Commercials", which first aired November 22 and December 2, affected "iPhone’s consumer perception, sending it into decline around the time the first ad appeared and continuing now," Ted Marzilli, YouGov BrandIndex managing director, said then. "At the same time, Samsung’s perception has crept up gradually and just surpassed iPhone last week".

But it's Samsung's innovation in the absence of Apple's that makes the difference. Remember, iPhone 4S wasn't the big upgrade everyone expected. In some respects, neither is Galaxy S III. Sure there's a quad-core processor, LTE and larger display (4.8 inches to Galaxy S II's 4.3 inch or 4.5 inch). But Samsung chose to pack in the big benefits elsewhere.

Apple's Luck runs Out

For that, Apple execs should consider themselves lucky that Samsung doesn't have a marketing personality like Steve Jobs and worry there's no "reality distortion field" peddler for iPhone 5. Galaxy S III promises some truly innovative software features supporting the hardware, most of which would have received "My God, Apple has done it again" blog, news and social media response if introduced by Jobs. Much of Samsung's innovation extends from the foundation that Google laid with Android 4 "Ice Cream Sandwich". Meaning: Other Android licensees can do it, too.

Will you buy Samsung Galaxy S III?

Rather than blow out the hardware specs, Samsung focused on benefits that make the phone more responsive to the user. The original iPhone stood apart from all other handsets, not just smart ones, for its humanness. Touch, and its intimacy, and the way the handset responded to your proximity gave it a human quality. Suddenly the phone wasn't an inanimate object but more living thing.

Samsung seeks to bring this quality to Galaxy S III, and it's centerpiece to the product marketing. For example, the front camera detects whether the user is looking at the phone and keeps the screen lit. How many times has your display gone dark while reading a website or ebook? The phone also can automatically turn on, if recognizing your face. The feature, called "Smart Stay", is real innovation, not Samsung copying Apple. It's also stark example of Samsung out-Appling Apple by focusing on features that offer real benefits. This and other new features match responsive capabilities to hardware sensors.

Still, hardware-wise, Galaxy S III is no slouch: 4.8-inch Super AMOLED display (306 ppi) with 1280 x 720 resolution; 1.4GHz quad-core processor; 1GB RAM; 16GB or 32GB storage (64GB in future), expandable with microSD card; HSPA＋ 21Mbps (850/900/1900/2100), 4G LTE, GSM/EDGE (850/900/1800/1900); 8-megapixel rear-facing and 1.9MP front-facing cameras; LED flash; zero shutter-lag; 1080p video recording; accelerometer; ambient-light sensor; gyroscope; GPS; proximity sensor; digital compass; NFC, Bluetooth 3.0; WiFi N; 2100 mAh battery; carrier locked; Android 4.0 and TouchWiz "nature" UI. Measurements: 136.6 x 70.6 x 8.6 mm, 133 grams.

The entire package definitely entices many of you. "The iPhone is a great phone to look at but looking at a phone quickly becomes boring", Roger Seabrook comments. "I have an S3 on preorder". Dallas Twiford: "I'll be buying this phone, it's a freaking beast".

I ask again: Will you buy Galaxy S III? Please answer in comments below and take the poll above, if you haven't already.

Facebook's IPO is a jackpot for some, despite dark shadow of mobile

Publié: mai 18, 2012, 7:49pm CEST par Tim Conneally

Today is Facebook Day, the day when the most-successful-social-network-so-far opened up to public investment and outshone all other American IPOs up to this point.

With shares initially priced at $38, Facebook (FB) opened at $42.99 on the Nasdaq at 11:30am EST on Friday. After a brief delay in trading on Friday, a reported 82 million shares (of 421.2 million) were traded in the first 30 seconds of availability, totaling $116 billion.

This surge and retreat in price is thought to have been the result of a communication lag for traders an anonymous Wall Street source told Business Insider on Friday.

But the high initial valuation, reportedly buoyed by 33 different investment banks underwriting the IPO does nothing to quash doubts about the long-term value of the popular social network in the face of shifting user behaviors.

Facebook, as we learned in the company's IPO amendment last week, has not proven its value in the mobile world at all.

"We do not currently directly generate any meaningful revenue from the use of Facebook mobile products, and our ability to do so successfully is unproven. We believe this increased usage of Facebook on mobile devices has contributed to the recent trend of our daily active users (DAUs) increasing more rapidly than the increase in the number of ads delivered. If users increasingly access Facebook mobile products as a substitute for access through personal computers, and if we are unable to successfully implement monetization strategies for our mobile users, or if we incur excessive expenses in this effort, our financial performance and ability to grow revenue would be negatively affected."

With today's Facebook IPO, the recent valuation of Pinterest at $1.5 billion, and the misfire of a Groupon IPO, skeptical onlookers are crying "bubble!" while a handful of small groups and individuals rake in the millions, and in some cases, billions.

Now in beta, ESET Smart Security 6 and NOD32 Antivirus 6

Publié: mai 18, 2012, 5:36pm CEST par Mike Williams

ESET has released NOD32 Antivirus 6 and Smart Security 6 to public beta, and is attempting to lure early adopters by offering a chance to win one of 500 one-year licences for Smart Security.

Top of the new feature list must be Anti-Theft, a web service which aims to help you locate missing devices. If you’ve enabled anything similar on your phone or tablet then you’ll know what to expect – you can log on with a browser, perhaps see the position of your device on a map, view grabs of the laptop’s screen, and so on but it’s still a welcome addition to the packages. (Although it’s in NOD32 solely for the beta: normally Anti-Theft will be in Smart Security only.)

And even if you don’t plan on making use of Anti-Theft, protect at least one device with it and you’ll automatically be entered in a prize draw to win a full one-year licence of Smart Security 6. The contest runs between May 17 and June 17, 2012, and there will be 100 winners every week, with the company notifying the lucky ones via email.

Elsewhere, the program’s new idle detection means it’s able to scan your system when you’re not around. Update rollback means you can easily revert to a previous edition of your database. And Smart Security’s firewall, along with the antivirus heuristics and cloud-based file reputation system have all seen notable improvements.

As ever, it’s important to keep in mind that these are betas, with some significant bugs. ESET report that the programs may current crash when restoring an object from quarantine, for instance, which could prove fatal if it’s a system-critical file that’s been tagged in error. Make sure you’ve a full system backup available before you install either package.

If that’s not a problem, though, first builds of Smart Security 6 and NOD32 Antivirus 6 are available now. Don’t forget to protect something with Anti-Theft right away to give yourself the maximum chance of winning a Smart Security licence.
