S3 Encryption With Porticor

Your Porticor appliance can encrypt data being stored to Amazon’s Simple Storage Service (S3). Porticor is the only system available that offers the convenience of cloud-based hosted key management without sacrificing trust by requiring someone else to manage the keys. Porticor’s split-key encryption technology protects keys and guarantees they remain under customer control and are never exposed in storage; and with homomorphic key encryption, the keys are protected – even while they are in use.

A variety of applications use S3 to store bulk data, and we support two different ways of enabling Porticor encryption with them.

  1. The first and recommended alternative is to configure the application so that data is written to and read from the Porticor appliance.
  2. Where this is not an option, you can instead configure host-to-IP mapping so that the application writing to s3.amazonaws.com actually writes to the appliance, which encrypts and forwards the data to S3.

These are two options to set up your environment, but the end result is one and the same: your data is encrypted when written to S3 and decrypted when reading from it, with no need to change the client application.

What follows are detailed instructions for both configuration options.

Alternative 1: Explicit Configuration

This alternative depends on the individual application. In fact some S3 clients are hardwired to the Amazon server addresses and cannot be configured. For these clients you must use Alternative 2.

In this alternative you configure the S3 client to connect to a special DNS address for each of your buckets and for the main S3 endpoint. These DNS addresses are installed automatically when you add your S3 “buckets” into the table on the S3 Encryption page. All buckets that are to be encrypted must be listed. If your bucket is called mylittlebucket, it will be mapped to the DNS name mylittlebucket.d.porticor.net.

The specific client configuration depends on the particular client. Following are two examples.

Configuring s3cmd

Edit the file $HOME/.s3cfg, and replace the host_base and host_bucket lines as below, where the long host_base value is your appliance’s address.

# old:
# host_base = s3.amazonaws.com
# host_bucket = %(bucket)s.s3.amazonaws.com

# new:
host_base = itbetb19zy3-pzjy3yty2zw.d.porticor.net
host_bucket = %(bucket)s.d.porticor.net

Configuring S3QL

Edit $HOME/.s3ql/authinfo2, and add a new section:

[porticor]
storage-url: s3c://itbetb19zy3-pzjy3yty2zw.d.porticor.net/bucket-name/
backend-login: aws-key-id
backend-password: aws-secret-key

To create the file system, run:

mkfs.s3ql --plain --ssl s3://bucket-name/

mount.s3ql --ssl s3://bucket-name /mnt/cloud-drive

Note the use of the “s3c” URL method. Both the --ssl and --plain flags are mandatory.

Alternative 2: Host Mapping

With this alternative you configure the host on which your S3 client is running, so that s3.amazonaws.com and bucketname.s3.amazonaws.com are resolved to the IP address of the Porticor appliance. You should not fill in the Bucket table in this alternative.
On Linux, edit the file /etc/hosts and add the lines shown below.
On Windows, add these lines to %windir%\system32\drivers\etc\lmhosts (or ...\hosts, depending on your Windows version).

Appliance-IP bucketname.s3.amazonaws.com # replicate this line for each S3 bucket
Appliance-IP s3.amazonaws.com

Use the so-called “private” IP address (10.x.x.x) of the Porticor appliance, for access from within the EC2 cloud. If you plan to access the appliance from outside the cloud or even from another AWS region you will need to use “public” address instead. Both addresses are listed in the S3 Configuration GUI page.
All communication with the virtual appliance is SSL-protected. In Alternative 2, you should make sure that your project’s CA certificate is installed on the client machine, otherwise your S3 client might refuse to connect.

Additional Notes

  • You need to wait a few minutes after the creation of a new bucket before starting to use it, so that it is recognized by all S3 servers.
  • Note that Porticor does not support “mixed buckets” containing both protected and unprotected objects.
  • Bucket names must conform with the requirements for DNS names, as recommended by Amazon Web Services. In particular they must not contain uppercase letters.

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
All major researchers estimate there will be tens of billions devices - computers, smartphones, tablets, and sensors - connected to the Internet by 2020. This number will continue to grow at a rapid pace for the next several decades. With major technology companies and startups seriously embracing IoT strategies, now is the perfect time to attend @ThingsExpo, November 3-5, 2015, at the Santa Clara Convention Center in Santa Clara, CA. Learn what is going on, contribute to the discussions, and ensure that your enterprise is as "IoT-Ready" as it can be.
Containers are not new, but renewed commitments to performance, flexibility, and agility have propelled them to the top of the agenda today. By working without the need for virtualization and its overhead, containers are seen as the perfect way to deploy apps and services across multiple clouds.

Contrary to mainstream media attention, the multiple possibilities of how consumer IoT will transform our everyday lives aren’t the only angle of this headline-gaining trend. There’s a huge opportunity for “industrial IoT” and “Smart Cities” to impact the world in the same capacity – especially during critical situations. For example, a community water dam that needs to release water can leverage embedded critical communications logic to alert the appropriate individuals, on the right device, as soon as they are needed to take action.
