Supermicro hardware weaknesses let researchers backdoor an IBM cloud server | killexams.com Real Questions and Pass4sure dumps

Supermicro hardware weaknesses let researchers backdoor an IBM cloud serverenlarge Jeremy Brooks / Flickr reader comments 53 with forty five posters participating Share this story

  • greater than 5 years have handed due to the fact researchers warned of the serious security hazards that a general administrative device poses to servers used for some of the most sensitive and mission-vital computing. Now, new research indicates how baseboard administration controllers, because the embedded hardware is called, threaten premium cloud capabilities from IBM and perhaps other providers.

    further reading “Bloodsucking leech” places one hundred,000 servers prone to robust attacks briefly, BMCs are motherboard-connected microcontrollers that supply impressive manage over servers interior datacenters. the use of the intelligent Platform administration Interface, admins can reinstall working methods, install or regulate apps, and make configuration changes to enormous numbers of servers, without bodily being on premises and, in many circumstances, with out the servers being became on. In 2013, researchers warned that BMCs that came preinstalled in servers from Dell, HP, and other identify-brand manufacturers have been so poorly secured that they gave attackers a stealthy and handy solution to take over total fleets of servers inner datacenters.

    Researchers at safety firm Eclypsium on Tuesday plan to publish a paper about how BMC vulnerabilities threaten a top class cloud carrier supplied via IBM and probably different suppliers. The premium service is called bare-metal cloud computing, an choice provided to purchasers who want to shop exceptionally delicate information but do not desire it to intermingle on the equal servers different customers are the use of. The top rate lets customers buy unique access to dedicated physical servers for as long as needed and, when the servers are not any longer necessary, return them to the cloud issuer. The company, in theory, wipes the servers clean so they can also be safely used by using one more bare-steel consumer.

    Eclypsium's research demonstrates that BMC vulnerabilities can undermine this mannequin by means of allowing a client to depart a backdoor with a view to continue to be energetic as soon as the server is reassigned. The backdoor leaves the customer open to loads of attacks, together with facts theft, denial of service, and ransomware.

    To show their factor, the researchers commissioned a bare-metal server from IBM's SoftLayer cloud service. The server became the usage of a BMC from Supermicro, a hardware company with a wide range of commonly used firmware vulnerabilities. The researchers validated the BMC changed into operating the newest firmware, recorded the chassis and product serial numbers, and then made a mild modification to the BMC firmware in the kind of a single bitflip interior a comment. The researchers also created an additional consumer account in the BMC's intelligent Platform administration Interface.

    The researchers then returned the server to IBM and requested new ones. at last, the researchers were assigned one with the same chassis and product serial quantity because the server that they had prior to now received and modified. An inspection of the server did not encourage self assurance. based on the file:

    We did notice that the extra IPMI user turned into eliminated by means of the reclamation procedure, besides the fact that children the BMC firmware containing the flipped bit become nevertheless existing. This indicated that the servers' BMC firmware became now not re-flashed all over the server reclamation process. The combination of using vulnerable hardware and not re-flashing the firmware makes it possible for a malicious party to implant the server's BMC code and inflict damage or steal facts from IBM consumers that use that server sooner or later.

    enlarge

    We additionally seen that BMC logs have been retained throughout provisioning, and BMC root password remained the equal throughout provisioning. with the aid of now not deleting the logs, a new client might benefit insight into the actions and behaviors of the old owner of the device, while understanding the BMC root password might permit an attacker to greater quite simply gain handle over the computing device in the future.

    now not the first time further studying To steer clear of hacking, disable well-known Plug and Play now Eclysium researchers are not the most effective ones to doc how weaknesses in Supermicro BMCs can put naked-steel cloud users in danger. In 2012, researchers at security firm Rapid7 found out that the Supermicro controllers have been susceptible to hacks transmitted over a laptop's familiar plug and play networking protocols that gave attackers unfettered entry. They went on to mix those insights with new findings from researcher Dan Farmer that showed a way to construct extremely tough-to-discover backdoors within the BMCs.

    To the chagrin of the researchers, they found the exploits endured to work in opposition t bare-metal servers despite new measures cloud suppliers delivered in an try and mitigate the vulnerability. HD Moore—who at the time was Rapid7's chief analysis officer and is now vp of research and building at Atredis partners—referred to an IPMI characteristic called a keyboard controller style made backdooring the BMC of naked-metallic servers viable. As was the case with IBM SoftLayer, a distinct cloud issuer didn't notice and re-flash modified firmware.

    "it is ridiculously bad to make use of a dedicated (bare-metallic) server if the BMC is enabled," Moore stated in an interview. "There is no make certain that the BMC hasn't been backdoored before your server became provisioned. The excessive-end cloud providers have hardware solutions to defend against these assaults, however any person the use of inventory supermicro boards is going to be in danger."

    In a longer message to Ars, Moore offered extra particulars around his research in 2012 and 2013:

    while investigating the influence of the libupnp vulnerabilities in late 2012, we determined that tremendous Micro BMCs had been affected and wrote a Metasploit module to profit far off root shells on those gadgets by way of that vector. presently after, in 2013, Dan Farmer launched his research into IPMI, and we endured searching on the publicity created by way of super Micro BMCs, with an eye in opposition t the capacity of each a number and a BMC to subvert every other. The method changed into lined in a blog post and we endured searching into super Micro BMC issues in conventional.

    One situation we looked at became no matter if committed server suppliers (what we call bare-metallic cloud these days) correctly covered the BMC interfaces and even if an assault on a rented server may result in everlasting entry to that hardware. We determined that this became viable and that there weren't any awesome options to it, but we only had just a few ISPs as records features. beginning in 2013, we saw principal alterations to how committed server providers included and remoted the BMC interfaces, however it wasn't sufficient to keep away from a everlasting backdoor from being delivered by means of an attacker.

    committed server providers replied to the general public vulnerabilities in IPMI and libupnp through putting the BMC community interfaces in the back of firewalls and altering the admin passwords on the BMCs in order that a casual consumer of the rented server couldn't interface with it. This failed to evade entry to the BMC, because the IPMI over KCS channel permits a brand new admin user to be created and in the case of tremendous Micro as a minimum, the firmware to be re-flashed. We proven that we may re-flash a committed server with an older edition of the firmware and then exploit it using the libupnp vulnerability.

    This resulted in examine access to the nvram of the BMC and a root shell within the BMC's Linux-based OS. The nvram contained the plaintext passwords, that have been shared throughout all servers at that particular issuer. We seen that the BMC may entry BMCs connected to different client's servers via the dedicated network, and that the firmware may well be modified in order that future updates would now not follow. making a malicious firmware picture for super Micro BMCs is trivial the usage of public tools (https://github.com/devicenull/ipmi_firmware_tools).

    We didn't submit these effects, but it surely led to greater due diligence on our part when picking out dedicated servers for our personal use, and rather a few conversations with Zach Wikholm at Cari.web, who became juggling connected issues of their statistics middle, including energetic exploitation of super Micro BMC vulnerabilities.

    In an announcement, IBM officers wrote:

    We aren't privy to any customer or IBM information being put in danger because of this stated skills vulnerability, and we've taken moves to dispose of the vulnerability. Given the remediation steps we've taken and the stage of difficulty required to take advantage of this vulnerability, we consider the knowledge have an effect on to consumers is low. while the document focuses on IBM, this became truly a potential trade-huge vulnerability for all cloud carrier suppliers, and we thank Eclypsium for bringing it to the attention of the industry.

    In a weblog post published Monday, IBM officials spoke of the countermeasures consist of "forcing all BMCs, including those that are already reporting up-to-date firmware, to be re-flashed with manufacturing unit firmware earlier than they're re-provisioned to different purchasers. All logs in the BMC firmware are erased and all passwords to the BMC firmware are regenerated."

    Moore, for his part, remained unconvinced the measure will safely protect in opposition t the BMC hacks because, he noted, "utility-based re-flashing equipment may also be subverted via an attacker that has already flashed a malicious picture. I do not suppose IBM can clear up it wanting physically disabling the BMC by way of a motherboard jumper."


    IBM Re-brands Storwize with New Storage solutions Lineup | killexams.com Real Questions and Pass4sure dumps

    more huge information from the cloud–IBM is launching a brand new product line of records storage options, all in the identify of re-branding efforts. Its Storwize acquisition has been renamed actual-Time Compression, unveiling a new website to move together with the changes underfoot.

    the brand new storage solutions goal to tackle the growing to be demand from companies, as they extend their infrastructure and virtualization wants. more reliance on these systems is empowering companies to work smarter and faster, with greater abilities to scale. To acheive that flexible scalability, these organizations are coping with a combo of unstructured statistics, replicated statistics, hardware and a couple of other sever traits.

    The cornerstone of IBM’s new sequence is the Storwize V700. It minimizes rack area us, and has application for managing data with a centralized user interface. including effortless Tier utility, the Storwize V700 is fast and reasonably effecient, in comparison to rivals inside its lowered funds of mid-tier storage techniques.

    Key points and examples of the brand new handy Tier utility:

    The IBM ProtecTIER deduplication know-how that IBM acquired in 2008 to assist customers eliminate duplicate copies of records and significantly increase storage effectivity;

    The IBM real-time Compression appliances — know-how that IBM acquired earlier this year to aid consumers cut back actual storage necessities by up to 80%, according to facts from currently put in home equipment (4);

    The XIV excessive-conclusion disk storage architecture that IBM acquired in 2008. XIV’s architecture makes it possible for it to adapt to altering workloads and deliver consistent high performance;

    IBM’s Scale-out community connected Storage (SONAS), invented by way of IBM analysis to help multiple petabytes of storage in a single file device. customers can additionally use XIV and SONAS together to create a complete cloud storage answer; and

    The IBM information Archive, which combines tape and disk storage to convey consumers a tiered storage device that can offer protection to records for lengthy-term retention whereas helping optimize prices.

    ***

    As IBM appears to maintain its dominate place amongst cloud capabilities, the business has devoted a great deal of analysis and construction, supplemented with a handful of acquisitions like Storwize, to extend its built-in cloud equipment. IBM notes the major enterprise issues surrounding storage solutions, which also delve into security considerations:

    “They’re beneath enormous drive to show this facts into insight, and grappling with how they’re going to save and cozy it all. IBM continues to advance ingenious storage applied sciences, using its large R&D spending to assist customers not best control statistics proliferation, but harness records to create insights for competitive merits.”

    IBM additionally added these days a number of other storage products, including:

    IBM device Storage DS8800, which in response to interior experiences, can present up to forty % quicker efficiency than its predecessor, the IBM equipment Storage DS8700 (6). The DS8800 will next 12 months help IBM effortless Tier.

    up-to-date SAN volume Controller application that comprises easy Tier, an more advantageous administrator GUI and elevated scalability as compared to the outdated version of the know-how.

    IBM techniques Director Storage handle application that manages storage, servers and network expertise through a single interface, reducing storage administration complexity, risk and value.

    NAND Rises to the Occasion in Data-Heavy IoT Applications | killexams.com real questions and Pass4sure dumps

    Download this article in PDF format.

    Long a staple of consumer devices such as MP3 players, digital cameras, and USB flash drives, nonvolatile NAND flash memory is raising its game to respond to the new challenges posed by data-heavy Internet of Things (IoT) applications (Fig. 1). IoT applications for NAND flash cover a breathtaking range: industrial automation and Factory 4.0, connected vehicles, wearables, healthcare, aviation, plus just about any application that begins with “smart”: smart metering, smart homes, smart utilities, smart farms, smart logistics, and more. 

    1. NAND flash memory finds a home in numerous data-heavy IoT applications. (Source: Delkin Devices)

    The smallest IoT applications—a remote edge node, for example—commonly use microcontrollers with embedded flash to store both code and data. Their storage requirements are quite modest, but with 30 billion connected devices forecast by 2020 and 75 billion by 2025, the data load rapidly increases at higher levels of the hierarchical IoT architecture: the area controller, gateway, and especially in the cloud.

    Applications at the edge node aren’t usually considered to be “data-heavy,” but perspective is everything. An aircraft in flight can be considered a mobile edge node from the point of view of Boeing, Airbus, or the airline. However, the sensors on a single jet engine can generate 20 TB of data every hour. Even with a 5G infrastructure, the manufacturer may find it preferable to cache the information during flight and upload it while at the gate rather than risk losing data due to a dropped connection or present an opportunity to hackers.  

    In other edge-node applications, say, a smart factory, nonvolatile storage can help a machine analyze operational conditions and respond in real time to alerts or faults. A repair technician could also access the last few days of sensor data locally to aid in troubleshooting.

    NAND flash is making inroads in the cloud, too. The NAND flash read-write speed is much faster than that of a hard-disk drive (HDD). Therefore, the initial cloud applications for all-flash storage are low-latency applications such as artificial intelligence (AI), real-time analytics, transactional databases, and machine learning.  

    The cost per gigabyte of flash storage is currently higher than for an HDD, although it’s dropping quickly. Consequently, HDDs or hybrid flash/HDD solutions are still preferred for secondary data applications like backup storage, digital imaging, and disaster recovery. 

    Manufacturers are continually working to reduce the cost-per-gigabyte of NAND devices, so device life cycles tend to be quite short with frequent process feature shrinks. Longer term, industry forecasters are predicting that NAND flash will replace HDDs in almost all cloud-storage applications.

    Overview of NAND Flash Operation

    A NAND flash memory cell (Fig. 2) is similar to a standard MOSFET, but it contains two gates rather than one. The control gate turns the channel on and off, and the insulated floating gate stores charge. When a floating gate contains electrons, it’s considered charged, or programmed. Otherwise, it’s considered uncharged, or erased. The drive registers the cell's bit value as logical “0” when a floating gate is charged and as logical “1” when the floating gate is uncharged.

    2. The structure of a typical single-level flash cell. (Source: Tech Target)

    Turning on the channel requires a threshold voltage VT to be applied to the control gate. If the floating gate is already charged, its effect is to increase the required threshold voltage to VT+; otherwise the required value of VT is a lower value, VT-. To read a cell, the controller applies an intermediate voltage between VT- and VT+. If the channel conducts, the floating gate is uncharged; otherwise, it’s charged.

    Unlike other memory technologies, a NAND flash device can’t be reprogrammed at the individual byte level. Due to its architecture, it can only be read and programmed in pages—typically between 4 and 16 kB—and can only be erased in blocks that range from 16 to 512 kB in size. A block must be completely erased before being reprogrammed. This two-step process is called a “program/erase” (P/E) cycle. Repeated P/E cycles lead to the breakdown of the oxide layer within the floating-gate transistor cells and eventual failure. Thus, the endurance, measured in number of P/E cycles, is a key specification.

    A NAND flash device requires an internal or external controller to implement error code correction (ECC), manage bad blocks, and perform wear leveling—a technique to increase endurance by counting writes and dynamically remapping blocks to spread writes more evenly. So-called “raw” NAND includes just the cells and requires an external controller. A fully managed NAND device integrates the controller.

    NAND flash devices come in different varieties, classified by the number of bits that can be stored in a single cell: single-level cell (SLC), multilevel cell (MLC), triple-level cell (TLC), and quad-level cell (QLC). As Figure 3 illustrates, there’s a tradeoff between cell endurance and cell density: the higher-density cells have lower endurance.

    More recently, manufacturers have begun offering three-dimensional (3D) NAND devices in MLC and TLC formats: current-generation 3D NAND devices stack up to 96 layers vertically for higher density.

    Individual devices are available with capacities from 128MB to 2TB. Smaller-density devices are popular in consumer IoT applications such as wearables, smart appliances, set-top boxes, and smart TVs. High-density products find a home in cloud storage, plus data-heavy IoT applications such as gateways, factory automation, industrial PCs, surveillance, and drones.

    There’s also a choice of interfaces. The embedded multimedia card (e.MMC) format uses an 8-bit parallel interface and integrates the flash memory and the controller into a 100-, 153-, or 169-ball-grid-array (BGA) package. The e.MMC version 5.1 specification has a 400-MB/s transfer rate.

    The Universal Flash Storage (UFS) specification employs a full-duplex LVDS interface for higher transfer speeds than e.MMC. The latest (2018) UFS 3.0 revision uses two lanes to achieve a maximum total bandwidth of 2.9 GB/s.

    NAND flash devices are offered in a variety of form factors, from single devices, to modules, to complete systems. Memory cards are used in both consumer and IoT applications; popular formats include USB flash drives, CompactFlash (CF), and secure digital (SD) cards in either standard or microSD sizes.

    Solid-state drives (SSDs) combine large numbers of NAND flash devices and are popular as HDD replacements in both consumer and IoT applications. At the high end, a typical all-flash drive for cloud storage might be rack-mountable with 48 individual SSDs and a total capacity of 34 TB. 

    Picking the Right NAND for Your IoT Application

    The IoT space covers a lot of ground, so there’s no “one size fits all” approach to picking a NAND solution. SLC NAND has the lowest density, but the highest performance and endurance. It’s preferred for high-end, mission-critical applications. MLC and TLC devices feature increasing density and lower endurance, and QLC devices are suitable for high-density, cost-sensitive mass-storage applications.

    Consumer-oriented IoT applications can use off-the-shelf components, but many other IoT applications have specialized requirements. For example, security is a high priority for secure boot code, firmware, keys, and other sensitive information.

    Standard commodity parts don’t include security features, but secure NAND flash devices offer volatile and nonvolatile block protection features. Volatile block protection locks one or multiple blocks until power is cycled; nonvolatile block protection permanently locks a fixed or variable range of blocks. Other security features include device-specific unique IDs, password protection, and AES256 data encryption.

    Since some security features are computationally intensive, they’re typically included in a module-level design, e.g., a secure SSD.

    An extended temperature range is important for IoT edge devices that are exposed to the elements or operate in a harsh industrial environment.   


    Best cloud storage of 2019 online: free, paid and business options | killexams.com real questions and Pass4sure dumps

    Best cloud storage of 2019

    Businesses and consumers are increasingly reliant on cloud based storage solutions instead of in-house, on-premise local storage hardware.

    Your files are stored in the cloud, which is a simplified view of what is essentially someone else's infrastructure (data center, server, hard drive, connectivity etc).

    Ever since Amazon popularised storage online with S3 (Simple Storage Service), 13 years ago, Google data shows that interest for "Cloud Storage" alone has increased by 40x over the past decade. So much so that people less frequently refer to it as "online storage".

    Given the multitude of cloud storage providers out there, one has to wisely choose a provider who will offer the maximum amount of low-cost storage and bandwidth, while still keeping your data safe.

    This list represents our top picks for cloud storage: most offer a free tier allowing you to see if they're right for you before handing over any hard-earned cash. 

    Business users will need to consider carefully what their needs are as terms and conditions as well as quality of service is likely to differ significantly from their consumer alterego.

    IDrive secures servers, desktop system and mobile devices with equal aplomb

    1. IDrive

    Storage solution which extends to cover network drives

    Fast

    Easy to use

    Good Security

    IDrive Express service is handy if disaster strikes

    No two-factor authentication

    IDrive offers continuous syncing of your files, even those on network drives. The web interface supports sharing files by email, Facebook and Twitter. Cautious or click-happy users will be pleased to hear that files deleted from your computer are not automatically deleted from the server, so there's less danger of removing something important by accident. Up to 30 previous versions of all files backed to your account are retained. 

    Another thing to note is that IT admins have access to IDrive Thin Client application, which allows them to backup/restore, manage settings, and more for all their connected computers via a centralized dashboard.

    For photos, you have a neat facial recognition feature that helps you to automatically organize them as well as syncing them across all your lined devices. IDrive also offers IDrive Express which sends you a physical hard disk drive if you lose all your data, allowing for the swift restoration of all your backed up files. That applies to the newly introduced disk image backup feature.

    A business version exists and offers priority support, single sign-on as well as unlimited users and server backup.

    pCloud delivers an affordable Cloud storage facility with a selection of apps 

    2. pCloud

    Ideal for those storing large media files

    Premium 500 GB Lifetime

    $175

    Affordable

    Elegant, intuitive interface

    Simple to use

    No collaboration tools

    While some bandwidth limits apply, there seems to be no limit to the size of files you can upload, so feel free to sync large media files with pCloud. The service is available for all desktop and mobile platforms – users can also log in via the website. The company itself is registered in Switzerland which has strong privacy laws and you can also pay a premium of $4.99 a month for pCloud Crypto to lock (and unlock) individual files with passwords. Note that it is one of the very few cloud services that offer lifetime subscriptions. The latter come with 30 days trash history and unlimited remote upload traffic (you only need the URL of the file); you are - as expected - limited on the download link traffic: 500GB for the Premium package and 2TB for the Premium Plus package.

    3. Mega

    Puts a premium on security

    Easy-to-use UI

    Extremely generous free offering

    Sync client is open source

    With an insanely generous free tier and a simple drag-and-drop interface, New Zealand-based Mega is one of the cloud storage heavyweights. There's a handy mobile app to allow you to upload files and photos, as well as sync clients with desktop machines. The company also has business tailored plans.

    Mega claims that all data stored in its cloud is encrypted on your device before it reaches the firm’s servers. As the company has released the source code to its sync client, experts can check that there are no vulnerabilities. 

    Price: 50GB free. 200GB for $6 a month (£4.50, €4.99, around AU$7.50). 1TB for $12 a month (£9, €9.99, around AU$16). 4TB for $23 a month (£17, €19.99, around AU$30). 8TB for $35 a month (£26, €29.99, around AU$46).

    4. OneDrive

    Backed by Microsoft and ideal for Windows users

    Low Stock

    Office 365 Personal

    Low Stock

    Office 365 Home

    Low Stock

    Office 365 Business Premium

    Integrated directly into Windows

    File restoration features

    Free storage is only 5GB

    OneDrive (formerly SkyDrive) is integrated into Windows 10's file explorer. You don't have to download an additional app – it's there to use out of the box, which is obviously very convenient for those who have made the jump to Microsoft’s newest operating system.

    Microsoft's Photos app can also use OneDrive to sync pictures across all your devices. There's an app for Android and iOS devices, and there's even one in the App Store for Mac users (although it has received mixed reviews).

    Price: 5GB free. 50GB for $3 a month (£1.99, around AU$4). 1TB for $8 a month (£5.99, around AU$11). 5TB for $11 a month (£7.99, around AU$14)

    5. iCloud

    Apple’s competitively priced cloud storage locker

    Reasonable pricing

    Tight integration with Apple’s platforms

    Only 5GB storage for free

    If you want to back up your iPhone to iCloud, you'll need more than the free 5GB allowance Apple gives you, but compared to rivals iCloud prices are very reasonable. 

    The Mac Finder app integrates iCloud Drive, where you can store any files you wish. Documents created in the iWork office suite are also saved to iCloud and can sync across your devices. Windows users can also sync their files with iCloud Drive using the official client, and access the iWork apps on the iCloud website. 

    Price: 5GB free. 50GB for $0.99 a month (£0.79, AU$1.49). 200GB for $2.99 (£2.24, AU$4). 2TB for $9.99 (£8, AU$13)

    6. Google Drive

    A smart option for Google fans and G Suite users

    Generous amount of free storage

    Integrated with Android devices

    Web interface isn’t the best

    Google Drive is a natural choice for owners of Android devices as it's already integrated, but users of other platforms may appreciate the generous free storage too. You can also store high definition photos on your mobile phone with companion app Google Photos, and make use of Google's own office suite (now known as G Suite). Also, upgrading to paid Google Drive plans is now called Google One (although it might not yet be available, depending on the region).

    Downsides include the fact that the web interface isn't very easy-to-use, although Windows and Mac users can download a desktop app to drag-and-drop files easily. 

    Price: 15GB free. 100GB for $1.99 a month (£1.59, around AU$2.50). 200GB for $2.99 a month (£2.35, around AU$4.10). 2TB for $9.99 a month (£8, around AU$13). 10TB for $99.99 a month (£74, around AU$130). 20TB for $199.99 a month (£148, around AU$260). 30TB for $299.99 a month (£236, around AU$426).   

    7. Box

    Well-known service with some powerful business options

    Supported by many apps

    Business plans with advanced security

    Free account file upload limit of 250MB

    Box's website currently seems to be pushing its Business plans as clicking ‘sign up’ takes you to the pricing page where for $15 per user (£11, around AU$19) you can benefit from advanced collaboration options and unlimited storage. But there is a 10GB free option, too.

    As Box has been around for a while, it is supported by a number of mainstream apps such as Google Docs and Office 365. It's also integrated with G-Suite, which means Docs, Sheets and Slides are automatically saved and managed in Box. The Box Sync client is available from the Downloads page for Mac and Windows, plus there's also an official Android client.

    Price: 10GB free. 100GB for around $10 a month (£7.50, around AU$13)

    8. NextCloud

    DIY cloud storage solution

    Innovative self-hosting solution

    Tailor your cloud locker to your needs

    Preconfigured setups available

    NextCloud isn’t an online cloud storage provider itself, but offers free software to download and install a cloud storage service on your own server. Using a server on your home network for cloud storage is much faster. You can also enable encryption and make sure the information never leaves your home network, which is far safer. 

    If you've no server or IT experience, you can even purchase a preconfigured NextCloud Box (if you can find one) which comes with a 1TB hard drive and will work with an inexpensive Raspberry Pi board to keep your data synced. Unfortunately, NextCloud Box is sold out but you can check out the alternatives on their website

    Price: Free to install and use. Self-hosting so storage costs vary.

    9. SpiderOak

    A ‘zero knowledge’ cloud storage provider

    Tight security

    Plenty of native clients

    Limited free offering

    SpiderOak is part of a new trend of zero knowledge cloud storage providers. The website claims that after installing the client your data is encrypted before syncing. Unfortunately since SpiderOak hasn’t made the client source code public, there's no way to confirm this. 

    The SpiderOakOne client is available for Windows, Mac and Linux as well as Android and iOS (although, both Android and iOS are read-only apps, meaning you can only view files, and can't upload or sync anything). You can also log in via the web interface but privacy lovers may prefer not to as it exposes your password to SpiderOak employees. 

    Price: 21-day free trial. 150GB for $6 a month (around £4.5, AU$8.25). 400GB for $11 a month (around £8.4, AU$15). 2TB for $14 a month (around £10.7, AU$19.25). 5TB for $29 a month (around £22.1, AU$39.9)

    How to choose a cloud storage service?

    Florian Malecki, International Product Marketing Senior Director at StorageCraft gives us his thoughts

    Organisations are often unclear about the best way to keep their files and systems safe, but there are plenty of preventative measures that can be taken to avoid the costly risk of downtime. Arguably the most important factor is backing up and recovering data quickly and efficiently. That is where cloud storage comes in.

    With most cloud services providers, companies can tailor coverage to meet unique recovery and budget requirements while enjoying access to data anytime, anywhere, with instant failover in a cloud built specifically for disaster recovery.

    The cloud combines low setup, management and overhead costs with high flexibility. The important thing is protecting and securing backups offsite and giving businesses peace of mind knowing that data is safe and secure.

    Key factors organisations should consider when moving to the cloud are:

    ● Keep backups on-site and off-site. With any data, redundancy is the key. Data copies should be kept both on-site and off-site. Off-site could be in the cloud, but it could also be backup images stored on a hot-swappable hard drive that you can take to a secondary location (i.e. a “poor man’s cloud”).

    ● Choose a cloud with recovery options. If it’s not possible to recover data locally, organisations need to have a backup strategy in place. Some cloud services will allow you to spin up a Virtual Machine (VM), even if local recovery is impossible. For systems that have zero tolerance for downtime, a cloud-based recovery option is the best option.

    ● Mirror critical data. 99.999% uptime is exceptional, but nothing is infallible. It is important to remember that, while uptime is great, errors do occur, and data can be accidentally deleted or somehow corrupted. For extra critical data, it’s wise to not only backup data in the cloud, but to mirror it to a geographically disparate region for extra assurance.

    Best free cloud storage in 2019

    Google Drive

    1. Google Drive

    Heavyweight cloud storage offering tied in with G suite apps

    15GB of space for free

    G Suite tools

    Backup and Sync desktop app

    Free storage allowance: 15GB (expandable)

    If you're a Google user, you already benefit from Google Drive integration, such as the ability to save email attachments from Gmail. However, anyone can sign up for the free cloud storage, even if they don't have a Gmail address, by creating a new Google account. Google is also in a process of releasing Google One as a sort of substitution for Google Drive, although depending on your region it might not be available yet.

    With 15GB of space for new users, Google Drive is one of the more generous cloud offerings, and there are occasional ways to boost this capacity free of charge. The catch is that this Google storage space is also shared with a user’s other Google services including Gmail and Google Photos.

    Mobile apps are available to allow easy access for iOS and Android users, and Google’s Backup and Sync desktop app lets you synchronize files from your PC to the cloud. Google Drive also includes online office tools for word processing, spreadsheets and presentations which can makes sharing files with others effortless.

    pCloud

    2. pCloud

    A smart service with a slick online interface

    Easy-to-use sharing options

    Smart desktop and mobile apps

    Plenty of options to boost your free storage

    Free storage allowance: 10GB (expandable)

    You might not recognize the name, but if you're looking for a decent chunk of cloud storage free of charge, pCloud could be just the ticket. To kick things off, you're given a fairly generous 10GB to play with, and there's a bandwidth allowance of 50GB of downlink traffic per month.

    While we're primarily interested in the free version of pCloud, note that you can upgrade to 500GB of space for a monthly plan of $4.99 (£3.70), or 2TB for $9.99 (£7.50) a month – both of which are great deals for storage. You also have annual and lifetime plans, which are a cheaper option in the long run.

    The initial 10GB free offering can also be expanded up to 20GB via an additional 4GB for completion of offers, as well as referrals that add 1GB each. It’s also worth noting that pCloud offers well-designed desktop and mobile apps that supplement the website for seamless integration into a user’s workflow.

    With no limit on file sizes, and simple sharing options, pCloud is a great way to send large files to friends and colleagues – it's even possible to share with people who aren't using the service themselves. Add in decent streaming options and a neat online interface, and pCloud is well worth a look.

    Microsoft OneDrive

    3. Microsoft OneDrive

    Another sterling storage solution, particularly for Windows users

    Great integration with other Microsoft products

    Can edit files online without downloading them

    Only 5GB of storage by default

    Free storage allowance: 5GB

    Coming from Microsoft – a company with plenty of money to throw at the cloud – it's a little disappointing to find that OneDrive doesn’t include more space free of charge. Free users get a mere 5GB of storage, although it's relatively inexpensive to increase this to 50GB.

    If you have Office 365, you'll automatically get boosted to 1TB of space, but not everyone wants an Office subscription.

    Like Google Drive's appeal to Google users, OneDrive will be a good fit for anyone who is committed to using Microsoft's services. There's neat integration with Outlook.com, for instance. OneDrive also ties in nicely with Windows 10, and there is a selection of reasonable mobile apps to facilitate access on the move.

    It's possible to share files with other people even if they aren't OneDrive users (complete with customizable permissions), and the ability to edit files online without downloading them is a welcome touch.

    Dropbox

    4. Dropbox

    Another big name with some great support for third-party apps

    Raft of platforms supported

    Loads of nifty features

    Only 2GB storage space initially

    Free storage allowance: 2GB (expandable)

    Dropbox is a stalwart of the free cloud storage world, with a web interface that remains streamlined and easy-to-use.

    Despite its popularity, Dropbox actually has one of the least generous free packages for new users (just 2GB), but there are various ways to boost this space without paying, including inviting friends to join (you get 500MB per referral up to 16GB), completing the Getting Started guide (250MB) and contributing to the Dropbox forum (which elicits 1GB per 'Mighty Answer' provided).

    DropBox really comes into its own when you start delving into the service’s extra features. There's a great collaborative working tool called Dropbox Paper that acts as a group workspace, and – if you install the desktop app – you can back up photos automatically. The File Requests feature also allows you to request another user to upload a file to your Dropbox account.

    There are desktop apps for Windows, Mac and Linux, and mobile apps including Android, iOS and even Kindle. This gives Dropbox broad appeal, as does the support for third-party apps and services.

    The web version of Dropbox lets you edit files without needing to download them, and really the only thing that counts against the cloud storage service is that most alternatives offer more space to free users.

    MediaFire

    5. MediaFire

    A highly experienced cloud storage operator

    Can boost free storage to 50GB

    Impressive UI and sharing options

    Adverts with free accounts

    Free storage allowance: 10GB (expandable)

    MediaFire has been around for over a decade, and those years of experience really show. You're given 10GB of free space initially, but you can boost this by an extra 40GB through activities like referring friends and following MediaFire's social media accounts. Few people would disagree that 50GB of free cloud storage is impressive. Free accounts carry ads, but this is a small sacrifice to make.

    There's support for large files up to 4GB, and the sharing options are very impressive, even allowing sharing with non-users.

    The web-based interface is excellent too, and MediaFire offers mobile apps for convenient uploading and downloading on iOS and Android. These make it easy to access files you're storing in the cloud, and include convenient features such as automatic photo syncing.

    Best business cloud storage of 2019

    Best business cloud storage

    1. SpiderOak

    Ultra-secure cloud storage with a simple interface

    Strong security

    Central device management

    No collaboration options

    SpiderOak is a collaboration tool, online backup and file hosting service founded in 2007. The platform allows users to access, synchronize and share data using a cloud-based server.

    The company places a strong emphasis on data security and privacy. They offer a cloud storage, online backup and sharing service which they claim uses a ‘zero knowledge’ privacy environment. This means the client is the only one who can view all stored data. Not even SpiderOak themselves have access to your data.

    SpiderOak’s main focus is on privacy and security. As a result, the tool itself has a very basic design. This makes the admin console and all central device management very straightforward to use. They also include a handy drag and drop feature for organising files.

    From the centralized device management dashboard, users can access settings for all applications such as backup selection and sharing. The dashboard also allows users to manage their accounts, set group permissions and gain insight into usage.

    Prospective business clients will need to contact SpiderOak’s Sales Team directly to obtain a quote. 500 users minimum is required.

    Online commentators have observed that SpiderOak lacks many of the collaboration tools available from other cloud storage providers.

    2. Tresorit

    Encrypt your files in place with Tresorit’s elegant apps

    14-day free trial

    End-to-end encryption

    Several enterprise packages available

    Tresorit is a cloud storage provider based in Hungary and Switzerland. It was founded in 2011. The provider emphasizes enhanced security and data encryption for businesses and personal users alike.
