Padlock Your Dropbox with USB Two Factor Authentication

Posted: 13 Aug 2015 12:46 PM PDT

Beef up your security

Dropbox

Dropbox is making it more difficult for the bad guys to infiltrate your online storage account, provided you take advantage of the service's new support for USB-based two-factor authentication.

Effective immediately, Dropbox supports Universal 2nd Factor (U2F) security keys as an additional method for two-step verification, albeit only if you're using Google's Chrome browser. This allows you to use a USB key to help prove your identity.

If you're not signing in from a Chrome browser, you can still use Dropbox's two-step verfication via text message sent to your phone or an authenticator app, support for which was added to the cloud service back in 2012. However, if you're to take advantage of U2F support, Dropbox says you'll be better off.

"Security keys provide stronger defense against credential theft attacks like phishing. Even if you're using two-step verification with your phone, some sophisticated attackers can still use fake Dropbox websites to lure you into entering your password and verification code. They can then use this information to access your account," Dropbox explained in a blog post.

To use U2F, you'll need a security key that follows the FIDO U2F standard from the FIDO Alliance. Once you have that, select the Security tab in your Dropbox account and click Add next to Security keys.

From then on, when logging into your Dropbox account, you'll type in your password as normal, followed by plugging your key into a USB port on your PC.

More than Peace of Mind?

This is a nice move by Dropbox, but since it's only supported in Chrome, it's also of limited value. Keep in mind that two-factor authentication still works when you don't have your USB key handy, and that's true of hackers, too. So, what's the use?

As Dropbox points out, using U2F rather than punching in a code sent to your phone can protect you from sophisticated phishing attempts. And that's really the main benefit here -- with U2F, you can be sure that you're unlocking the correct the door.

That said, Dropbox isn't without its weaknesses. While your data is encrypted, it's not client side end-to-end encryption. In other words, Dropbox owns the keys to decrypt your data, which leaves it susceptible to disgruntled employees, government seizures, and hackers.

None of this makes Dropbox a bad service, just understand that even if you use U2F, there are still ways for your private data to be exposed.

Microsoft Changes Rules for Windows 10 Activation (for the Better)

Posted: 13 Aug 2015 10:32 AM PDT

No more searching for keys

Windows 10

Microsoft hasn't done away with Windows activation in Windows 10, though it did make things easier for users who perform clean installs on occasion. Once you upgrade and activate Windows for the first time, you can perform subsequent clean installs without having to track down your product key.

In fact, according to Ian Paul at PCWorld, you can't even find your product key in Windows 10 after upgrading. Instead, utilities like Magical Jelly Bean KeyFinder and Belarc Advisor return a generic key -- if you're running Windows 10 Pro, you'll see VK7JG-NPHTM-C97JM-9MPGT-3V66T, the same key that's used for build 10240.

The reason for this is because Microsoft is moving to "digital entitlements." The way Microsoft explains it, once you upgrade to Windows 10, the activation state from your previous version of Windows is carried over.

"Once activated, a digital entitlement for your PC's hardware is created in the Windows 10 activation service, This entitlement can be used by the same PC again for re-activation of the same Edition of Windows 10 in the future," Microsoft explains.

In Windows 10, your PC's activation status is stored in the cloud, so once you've activated Windows 10 for the first time, you won't have to worry about it ever again. If you perform a clean install afterwards -- maybe you were hit by a virus or want to zero-fill your drive -- your system will activate on its own without you having to hunt down and enter in a product key.

What happens if you upgrade your hardware and perform a clean install? According to ZDNet, swapping out your graphics card or storage drive shouldn't trigger a reactivation. If it does, you'll need to call Microsoft's activation hotline.

The bigger issue is motherboard replacement. As before, Microsoft recognizes a new motherboard as a new PC, which means your digital entitlement will likely go right out the Window, prompting the need to call in for reactivation.

PC Giant Lenovo Chants ‘We’re Number One!’ While Slashing 3,200 Jobs

Posted: 13 Aug 2015 09:01 AM PDT

Rough quarter

Lenovo Motorola

Lenovo said it's planning to reduce its workforce by around 5 percent, which works out to 3,200 job cuts. It's a cost cutting measure that Lenovo anticipates will reduce expenses by about $650 million in the second half of this year, and $1.35 billion annually.

News of the staff reduction came as Lenovo reported financial results for its first fiscal quarter ended June 30, 2015. Quarterly revenue came to $10.7 billion, an impressive figure on its own, but down three percent year-over-year. More troubling for Lenovo is that its net income fell 51 percent year-over-year to $105 million.

Lenovo blamed the disappointing figures on "significant declines in the global PC and tablet markets," along with slowed growth and increasing competition, particularly in China, in its smartphone business.

Looking to expand its portfolio and become a bigger player in mobile, Lenovo acquired Motorola from Google for $2.91 billion less than a year ago. That gamble hasn't paid off just yet, and even worse, Lenovo said it plans to write off $300 million in unsold smartphone devices, plus spend $600 restructuring its mobile business.

As for PC sales, Lenovo is still the biggest player around in terms of shipments and market share, having now been in the top spot for nine consecutive quarters. This is despite facing "perhaps the toughest market environment in recent years."

Lenovo collected $7.3 billion in quarterly sales from its PC Group, which includes PCs and Windows tablets. That's an 8 percent decline annually, though that's a reflection of the market, not Lenovo's ability to sell computers -- the OEM reached a record high 20.6 percent global market share on 13.5 million PC sales during the quarter, and widened its lead over Hewlett-Packard in the process.

"We will reduce costs in our PC business and increase efficiency in order to leverage industry consolidation increase share and improve profitability. We will come through these efforts as a faster, stronger and better aligned global company," said Yuanqing Yang, Chairman and CEO of Lenovo.

Even though Lenovo still leads the PC market, it has to be careful not to scare off customers. Fresh off the Superfish scandal, in which it was found that pre-loaded software on some Lenovo systems posed a security threat, it was recently discovered that Lenovo was using a BIOS firmware feature to download its software onto PCs even if a user wipes his/her storage device and performs a clean installation of Windows.

Synology DiskStation DS2415+ NAS Review

Posted: 13 Aug 2015 12:30 AM PDT

In the NAS world, bigger is definitely better

NASes are becoming more common, not just in the office space, but at home. As faster Internet connection speeds become more common, it's likely that more storage space will be required. But what if you stored everything on your PC? While we suspect a lot of people take this approach, the better approach would be to store media and archival files on a NAS, making the files accessible to any client PC, regardless of whether a "main" PC is down.

Last time, we took a look at QNAP's beastly TVS-871 NAS; this time, we look at an equally compelling option from another big name in the NAS business: Synology.

Before we continue, we'd like to point out that the vast number of home/casual users wouldn't need the product in this review. However, for business users and home users with a serious need for data capacity, redundancy, and availability, extra consumer-oriented features such as HDMI output aren't necessary.

Enter the Synology DiskStation DS2415+, a 12-bay NAS that focuses on several key features: high availability, total storage capacity, and expansion. Here are the specs:

 Synology DiskStation 2415+ Specifications
Storage ManagementSingle disk, JBOD, RAID 0, 1, 5, 6, 10, hot spare
RAID migration: 1 to 5, 5 to 6, basic to 1, basic to 5
Synology Hybrid RAID (SHR)
High availability (not available when using SHR)
Online volume expansion
Online RAID capacity expansion
Online RAID level migration
Global hot spare
Storage expansion via DX1215 x 1
Bad block scan and hard drive S.M.A.R.T.
Bad block recovery
RAID recovery
CPUIntel Atom C2538 Quad-core 2.4GHz
Memory6GB DDR3 (expandable from 2GB default)
SSD CacheNone configured
HDD12 bays (8 TB drive support), total capacity of 96 TB
VideoNot supported
Network4x 1Gb Ethernet
USB4x USB 3.0
Supports USB printer, drive, USB hub, UPS, Wi-Fi dongle
Cooling2x 120mm rear exhaust
Power500W
Expansion1x Expansion ports
Dimensions270 (H) x 300 (W) x 340 (D) mm
Weight9.24 kg / 20.37 lbs (without drives)
OSDSM 5.2 embedded Linux
Extras2x CAT6 Ethernet cables

For the detailed list of specifications, check out Synology's page on the DS2415+. It's necessary to note that the DS2415+ doesn't offer 10GbE expansion, so you're limited to 1Gbit infrastructures. If you want higher throughput on the DS2415+, you'll need to enabled link aggregation and have a network switch that supports 802.3ad.

Synology Diskstation Ds2415 001

The front's design is simple. Drives are removed by pushing in the lock side side of each cage. For those who might be relocating, we recommend removing all drive cages before transporting the NAS, as the unit is very heavy when fully loaded. Even with drive cages locked, it's possible to have a cage come loose with enough force.

Synology Diskstation Ds2415 002

The rear of the DS2415+ is equipped with four USB 3.0 ports, four 1Gbit Ethernet ports, a console port, and one DiskStation expansion port. There are dual "smart" 120mm exhaust fans on the rear that operate in high speed mode one the system detects that one fan has failed. You can of course, replace the fans if you wish, and as long as they're PWM fans, the failover feature will stay intact.

On the rear of the DS2415+ you'll find four 1Gbit Ethernet ports that can operate individually or bonded under 802.3ad link aggregation. This means that you can technically bond all four ports for a total maximum throughput of 4Gbit/sec, but under link aggregation, you'll need multiple IO transactions to take advantage of the extra bandwidth. With a single file transfer, you won't go above the bandwidth of one single link. You'll also need a managed switch that supports link aggregation. For the best throughput, it's still best to have a fatter pipe. The DS2415+ does not have 10GbE expansion capabilities. Synology claims a maximum aggregated throughput of 451MB/s reads and 415MB/s writes when all four Ethernet ports are bonded.

Netgear ProSAFE XS708E

In our previous review, we used an ASUS RT-AC87U AC2400 router for our network tests, but have since moved to a Netgear ProSAFE XS708E 10GbE switch. This will allow us to test NASes without a low bandwidth ceiling, since the XS708E supports link aggregation as well as a full 10Gbit/sec of performance on all 8 ports.

Netgear ProSAFE XS708E

For our aggregation tests, we bonded ports 1 and 2, and 3 and 4 on the XS708E.

DS2415+ features

The DiskStation DS2415+ is packed full of features such as: OpenERP, web hosting, Plex Media Server, WordPress, VPN Server, and a host of others that are all available as appliance downloads through Synology's Package Center. Other more advanced features such as VMware vSphere and Windows Server 2012 virtualization are supported as well as lightweight application appliances. The Intel Atom CPU inside the DS2415+ isn't intended for heavy-duty purposes, but the DS2415+ isn't positioned as an all-in-one server—it's primarily targeted as a storage device.

Synology's application repository isn't as expansive as QNAP's, but it has most of what you'll likely be using the DS2415+ for. One interesting feature is Synology's CMS, which is a central management application used to manage multiple Synology NASes through one NAS.

Synology DiskStation DS2415+

Above, you can see the DS2415+ managing an eight-bay Synology DS1815+. Through CMS, you can manage all aspects of the other NASes, including installing and removing appliances, volumes, etc. If you have multiple Synology NASes, CMS is a ultra convenient utility to have. With CMS enabled, two-factor authentication must be disabled, which reduces security. Hopefully, Synology will find a way to support two-factor authentication. You can use Google Authenticator with any Synology NAS running a recent version of DSM.

The DS2415+ also comes with what Synology calls High-Availability, which runs a heartbeat daemon that syncs and failover between two Synology NASes. HA is available as part of the DS2415+ and so there's no added cost for the feature.

Synology DiskStation DS2415+

For high-availability to work, you will be required to use two Ethernet ports per NAS and one will act as a passive server, only kicking in if the first one succumbs to a severe failure. We suspect business users will find this solution useful for mission critical data integrity.

Configuration

We configured our DS2415+ with 12 (yes, all 12 bays) Seagate Enterprise NAS 5TB drives, giving us a total raw capacity of 60TB. Seagate offers its Enterprise NAS drive in capacities up to 6TB.

We previously used desktop-level NAS drives, but for a NAS with 12 drive bays, we highly recommend going to enterprise-level drives from your favorite vendor. With 12 drive bays, there's increased vibration through the NAS chassis, although the DS2415+ does a good job of keeping vibrations to a minimum. Enterprise NAS drives have several key difference that make them more reliable, such as spindle motors that are mounted and fixed on both ends. Desktop drives, on the other hand, have the motor mounted to the drive body only at the motor's base.

Synology supports SSD caching in the DS2415+ for faster read/write performance, but you'll be required to use two identical SSDs. The DS2415+ will automatically create a mirrored cache between the two SSDs. We did not test with SSD caching.

Synology Hybrid RAID (SHR)

We used RAID 6 in our configuration since we're using a set of identical drives. However, Synology offers what it calls Hybrid-RAID, which allows users to mix and match different hard drive capacities to expand a RAID volume. For situations where obtaining a full set of identical drives isn't economical, Synology Hybrid RAID elevates traditional RAID volume drawbacks, such as having to destroy and recreate an array when upgrading.

Synology Hybrid RAID SHR

SHR is offered in single- and dual-disk failure formats (similar to RAID 5 and RAID 6, respectively). However, Synology admits that there's a slight performance hit to using SHR versus a classic RAID setup. The benefit, of course, is the support of drives of varying capacities as well as space optimization. To increase the capacity of a classic RAID setup, all drives in the volume must be upgraded. With SHR, you can upgrade any drive at any given time.

An interesting scenario one might consider is a full volume upgrade. Take our DS2415+ with 12 Seagate Enterprise NAS 5TB drives as an example. With SHR enabled, we can technically upgrade the entire array to 6TB drives by removing one drive at a time and replacing it with a larger-capacity drive. In single-drive failure SHR, we would let the array rebuild and then repeat the procedure with the next drive. Granted, this isn't a very fast way to upgrade a volume, but it does make it possible to do a capacity upgrade while hot.

If you plan to go down this path, we recommend using SHR with two-drive failure support instead of one-drive, so you don't put your array in a risky degraded mode during the upgrade procedure. 

Tests

We tested several features of the DS2415+, including RAID fail, rebuild, and throughput. We also tested dual link-aggregation mode from NAS to NAS.

Tests were done with the following hardware:

 Test bed
MotherboardASUS Rampage IV Black Edition
CPUIntel Core i7-3970X
RAMSamsung "Green" DDR3 32GB
SSDSamsung 850 Pro 1TB x 2 (RAID 0)
OSWindows 10 Professional
SwitchNetgear ProSAFE XS708E 10GbE
CableCAT7 7ft

Note: Thanks to CyberPower PC for supplying the Samsung 850 Pro 1TB SSDs!

THE BENCHMARKS:

File Copy Read (CIFS)117.1 MB/sec
File Copy Write RAID 5103 MB/sec
File Copy Read RAID 5103.6 MB/sec
File Copy Write RAID 6101.1 MB/sec
File Copy Read RAID 6107 MB/sec
File Copy Write RAID 10116.8 MB/sec
File Copy Read RAID 10115 MB/sec
Single Drive 1TB Active Rebuild (hh:mm:ss)01:49:02
Single Drive 1TB Non-Active Rebuild (hh:mm:ss) 01:38:41
Aggregation tests (dual port @ 2Gbit/sec negotiated link):
TestScore
Dual 6GB File Copy Write (NAS to NAS)222.2 MB/sec
Dual 6GB File Copy Read (NAS to NAS)231.8 MB/sec

Clearly there's performance gains to be had in link aggregation mode, which is where you can see substantial throughput gains. Strictly speaking though, link aggregation performance depends more on simultaneous I/O threads and doesn't at all help single threaded operations, such as copying one file at a time. Mixed file size copy operations of a 1TB folder performed at a more modest 97MB/sec, which is still excellent for 1Gbit networks.

iSCSI target tests:

Windows iSCSI Initiator

If you're using Windows as a client OS, iSCSI support is built in. You can launch the iSCSI initiator and simply enter the IP of the NAS. Once added, you'll need to go into Disk Management and initiate/format the iSCSI LUN as you would a normal disk, giving it a drive letter for access.

TestScore
File Copy Write (iSCSI)103.2 MB/sec
File Copy Read (iSCSI)107 MB/sec

Performance is similar to file-sharing protocols such as SMB and AFP, with the major difference being that iSCSI is a block-level protocol. You can format an iSCSI target to any file system you desire, such as NTFS or HFS. However, because the iSCSI target behaves like a real mounted drive, the LUN is locked to a single client (you can create multiple iSCSI LUNs on the DS2415+). Also, keep in mind that you won't be able to use link aggregation in conjunction with iSCSI. Lastly, you'll have to be mindful about properly connecting and disconnecting an iSCSI LUN.

Serious storage for serious customers

Synology's DiskStation DS2415+ packs in a lot of features for small-to-medium size businesses, and we can imagine plenty of verticals where a 12-bay NAS makes a lot of sense. There's plenty of room for storage expansion, and if you run out of space, the DS2415+ supports an additional 12 bays via Synology's DX1215 expansion unit.

We have just a few minor complaints about the DS2415+. First, there's no support for RAID 50 or 60, but we reckon this could be added via new firmware. Second, at larger-capacity configurations, 10GbE support would have been nice. While quad-port link aggregation is good, having a fatter pipe is better. Synology also needs to fix the two-step verification caveat with CMS.

The ideal scenario for the DS2415+ is that of volume, lots of it. While the DS2415+ supports features that consumers may find useful or entertaining, it performs best as a gargantuan storage repository. At this point in time, it supports 8TB drives, giving a total raw capacity of 192GB if you add in the DX1215. If you're running a substantial image/video heavy operation, you'll find the combo highly attractive.
