SFTP access to Cloud Storage

Cloud Storage SFTP

Storage Made Easy® have now made live a new SFTP protocol adaptor. SFTP is one of the two primary technologies for secure FTP networking, the other being FTPS, which Storage Made Easy already supports (along with FTP, WebDav, Secure WebDav and S3).

The primary reason we investigated implementing SFTP is due to a government POC in which access was required to secure AWSGov Cloud files from medical terminals. This was the primary requirement, but because Storage Made Easy works with almost any back-end Cloud. once added, it can be used as protocol gateway for any cloud mapped to an account, note that the Port is 2200

Below is an example of using the SFTP protocol to access a Storage Made Easy account using Transmit (a Mac App).

Transmit Cloud SFTP

Once connected, all data and mapped clouds are accessible.

SFTP RackSpace Cloud Files

Access can also be done directly from the command line.

Once connected we can do an ‘ls’ to get a file listing and the view of the files is similar to our earlier UI view.

New Feature Added: Real Time Document Collaboration

Real Time Document Editing

We have added a new feature to the Storage Made Easy platform, real time document collaboration. This is available for team account or Enterprise File Share and Sync on-premise users. It enables real time document editing between team members when online editing using the web document editor. It enables multiple users to open a document at the same time, and enables with everyone to contribute and/or review the document in real time.

This editing facility is available for any document in any cloud that is mapped to work with SME, be it public or private storage (for EFSS on-site users).

The below video shows the feature in action.

Accessing OpenStack, RackSpace, Google Drive, OneDrive, DropBox + more using Storage Made Easy and Transmit for Mac

If you have come across this post whilst researching how to access other storage clouds from Transmit then have a look at our Getting Started Guide to show you how you can register for a free account and get on with mapping your chosen Storage Cloud to the SME Cloud Gateway. When you are ready you can register for a free account here.

As many of you who use it know, CloudDav, from SME adds a WebDav layer over any Cloud, even if the underlying clouds do not support WebDav. SME does no however allow the native Mac WebDav client to connect direct because the performance of the native Mac WebDav client is notoriously abysmal for those with large amounts of files.

You can however choose to use other Mac clients to connect to the Cloud Providers that you have mapped to the SME Gateway. We highlighted Forklift as such a client in a prior post, and you can also choose to use Transmit from Panic.

Once you have CloudDav enabled you can choose to access your clouds, mapped via the SME Gateway, through Transmit. First choose to connect over WebDav as in the screenshot below:

Transmit DropBox

You can then choose to connect directly inside of Transmit or as a Virtual Drive that will appear in Finder.

Transmit  also has a very nice sync feature that will sync between folder structures. In this way you can sync files with Transmit and SME from different Cloud Storage Providers to your desktop.

SME CloudDav is available with every account, even free accounts, although on free accounts it is restricted to 150MB of use per month. The CloudDav protocol Adaptor is just one of the protocol adaptors that SME provides, the others being FTP, SFTP and a compatible S3 API. All protocol adaptors are available in the Storage Made Easy Enterprise edition as part of the Cloud Gateway which the SME Enterprise File Share and Sync is built upon.

In a post PRISM world why your Company needs joined up File Sharing and Governance

The recent controversy with regards to Prism and data snooping has brought the security of corporate data to the fore however the biggest threat to corporate data lies not with the corporate nemesis that is Prism but with the number of data leaks that occur every day in companies.

These include new phenomena such as Bring Your Own Device (BYOD) and Bring your Own Cloud (BYOC) as well as the thorny issue of what files are shared over email.

Data is any companies biggest asset and not controlling how corporate data is disseminated is a ticking time bomb waiting to explode in your company. Why? Take your pick, Legislative reasons, fraudulent reason, competitive reasons. There are many reasons why not controlling data dissemination could trip your company up.

Companies need to consider how to build an Effective data governance serves ACROSS their enterprise data silos. Doing so will define a cohesive set of parameters for data management, data usage, as well as the ability to create governance processes for a companies internal use, and for their supply chain, which ultimately leads to information assets that are well managed.

SME Data Governance framework

In the world of Cloud it is key that Data Governance and data policies work not only with data behind the corporate firewall but also cloud data and cloud services.

So what should you consider as a company to manage your data assets ?

1. Understand what information is sensitive across all data silos, have a federate access control mechanism that works with your user across this private and cloud data silos. Storage Made Easy provides such a federate mechanism to assign and control user permissions and access at a very granular level that overlays one or more data stores.

SME federate permissions

2. Set policies for data access and enforce them through common tools. For employee sharing of data through tools such as email, make it easy but also set policies that can define expiry time and password protection. Storage Made Easy has plug in’s for Microsoft Outlook and Mac Mail that enables productive file sharing across all cloud / private data but which has built in support for policy enforcement.

Mac Mail large file sharing

These policies should also ripple through to the mobile Applications used in a company:

iOS secure file sharing

3. Use Cloud Encryption for sensitive data and ensure that you control the private key. See our previous post on encryption and securing data for further information.

4. Audit all your company data. Irrespective of the policies set you should get in the habit of auditing your company data. SME enables the setup of an automated email to a specified user of the previous day file events such as sharing, files updated etc.

5. Set BYOD policies and device access policies that work like your company works. For example, have a contract firm that you gave access to a specific folder ? Then designate that they can only access the folder using a web browser and only from a specific IP address.

BYOD GEO Restrictions

Summary

Companies need to connect disconnected information to enable corporate governance.

How to encrypt, secure and access sensitive cloud storage data

**Updated 1st July 2016*

The recent PRISM Data snooping controversies have heightened almost every companies awareness of the potential vulnerabilities of data stored off-premise in the Cloud. Many Cloud Storage companies’ talk about encrypting data ‘at rest’ but the real issue is that the storage companies control the encryption rather than the company whose data is stored controlling the private key.

One of the features that Storage Made Easy provides is an encryption feature that can encrypt data uploaded to remote (and local) Cloud Storage. SME supports 50+ cloud storage vendors, which means companies are able to take advantage of private key encryption for some, or all data, across cloud storage providers.

For individual users of our cloud SaaS services SME  uses a key entered by a user to encrypt data, but  the key is not stored on the SME hosted service. If the key is lost, or forgotten, then when trying to subsequently access the file the user will not be able to gain access to the file as the correct key phrase will not be known.

For companies that use the SME SaaS hosted service team Admins specify a key that uses a similar mechanism but is applied to all users. Unlike the personal encryption the key phrase is either stored encrypted by the SME service, or it can be stored with a self hosted Vault instance.

For enterprise users who self-host the SME service then the key is can be stored on the service behind the corporate firewall or again it could use the open source Vault software on a key server.

Encryption file SME

SME uses AES-256 encryption using the Rijndael cipher, with Cipher Block Chaining (CBC) where the block size is 16 bytes. A random initialisation vector is generated when the user supplies an encryption key. The cipher Rijndael consists of:

– an initial Round Key addition
– Nr-1Rounds
– a final round.

The chaining variable goes into the “input” and the message block goes into the “Cipher Key. The likelihood of recovering a file that has been encrypted using our encryption is fairly remote. The most efficient key-recovery attack for Rijndael is exhaustive key search. The expected effort of exhaustive key search depends on the length of the Cipher Key and for a 16-byte key, 2127 applications of Rijndael.

Data_SecurityOnce files are encrypted in this manner they can be accessed by an of the comprehensive SME desktop (Web, Mac, Windows, Linux) or mobile tools (Windows Phone, iOS, Android, BlackBerry). When an encrypted file is accessed the user is prompted to provide the private key phrase before the file can be opened.

Encrypted file phone

 

If the file is accessed direct from the underlying storage then it will not be able to be used as it will be encrypted and without being opened via the SME service, either hosted or on-premises, it will not be able to be un-encrypted. This makes sensitive data stored on remote servers ultra-secure.

The SME also on-premises Cloud Control service resides behind the corporate firewall. It enables the ability to keep very sensitive data behind the corporate firewall but still enable secure file sharing and at the same time offers the ability to encrypt data that is stored on remote cloud storage and other SaaS services for additional security.

SME Encryption

The Storage Made Easy Cloud Encryption service is available to all SME users inclusive of free, Personal Cloud, Business Cloud and Enterprise Cloud

Cloud Computing Use Case: Extending Remote Desktop with a Cloud Drive

Many service providers and companies offer Remote Desktop Services to enable companies to access their desktop remotely. Applications are installed for the users where user settings and data are saved to their profile.

We’ve had a few requests from companies and service providers now who wanted users to easily be able to access data on remote clouds (such as Azure, DropBox, Box, FTP, WebDav, Sharepoint Amazon S3 etc) from a remote desktop.

With Storage Made Easy, this is easily done as SME presents a WebDav entry point to all clouds that SME supports whether they support WebDav or not. This means the service provider needs only co-locate the SME software appliance (supplied as an OVF compliant file) in their network and add a simple script to the users startup. The script it:

NET USE * \\webdav.storagemadeeasy.com@SSL\DavWWWRoot
pause

This enables user to get a mapped drive to remote cloud storage as soon as they login to their remote desktop and to browse and access these files like any other data drive and is a simple solution for bringing remote clouds directly into a users remote desktop using a simple metaphor they understand, “a drive”.

Storage Made Easy made easy provides free WebDav access to Clouds that don’t support WebDav

We are now giving away 150MB of free WebDav access to mapped Clouds to all SME free accounts. This is enough to access around 300 documents on Mobile devices per month and is enough for the average use of WebDav into Clouds such as DropBox, Google Drive, SkyDrive etc.

If you want to access more than just pay a one time $5 fee and get access to 2GB per month of WebDav for the life of your use of our service. If you want unlimited use then just sign up to be a personal cloud or business cloud user.

Also, all free accounts feature 5GB free storage on Amazon S3 and the ability to add up to 3 other Clouds that you wish to access.
