VPN Support for Heroku Private Spaces

news , Product Manager

Today we're excited to announce Site-to-Site Virtual Private Network (VPN) support for Heroku Private Spaces. Heroku customers can now establish secure, site-to-site IPsec connections between Private Spaces on Heroku and their offices, datacenters and deployments on non-AWS clouds.

VPN is a powerful, proven and widely-adopted technology for securely combining multiple networks (or adding individual hosts to a network) over encrypted links that span the public Internet. VPN is well-understood and in use by most enterprise IT departments, and is supported on all major cloud providers and by a range of hardware and software-based systems.

Internal Routing for Private Space Apps

news , Product Manager

Today we’re announcing a powerful new network control for apps running in Heroku Private Spaces: Internal Routing. Apps with Internal Routing work exactly the same as other Heroku apps, except the web process type is published to an endpoint that’s routable only within the Private Space and on VPC and VPN peered networks (see the Private Space VPN support companion post). Apps with Internal Routing are impossible to access directly from the public internet, improving security and simplifying management and compliance checks for web sites, APIs and services that must not be publicly accessible.

Seccomp (short for security computing mode) is a useful feature provided by the Linux kernel since 2.6.12 and is used to control the syscalls made by a process. Seccomp has been implemented by numerous projects such as Docker, Android, OpenSSH and Firefox to name a few.

In this blog post, I am going to show you how you can implement your own seccomp filters, at runtime, for a Go binary on your Dyno.

Why Use Seccomp Filters?

By default, when you run a process on your Dyno, it is limited by which syscalls it can make because the Dyno has been implemented with a restricted set of seccomp filters. This means, for example, that your process has access to syscalls A,B and C and not H and J...

Today we are proud to announce that Heroku has achieved several important compliance milestones that provide third party validation of our security best practices:

  • ISO 27001 Certification: Widely recognized and internationally accepted information security standard that specifies security management best practices and comprehensive security controls following ISO 27002 best practices guidance.
  • ISO 27017 Certification: A standard that provides additional guidance and implementation advice on information security aspects specific to cloud computing.
  • ISO 27018 Certification: Establishes commonly accepted control objectives, controls and guidelines for implementing measures to protect...

Securing Dependencies for Rails 5.2 Active Storage

engineering , Software Engineer

The Public Cloud Security (PCS) group at Salesforce partners very closely with Heroku engineering to review and advise on new product features across the platform, from infrastructure to applications. One of the most rewarding aspects about this partnership and working on this team for me is when we not only identify security concerns, but take an active role in building safe solutions.

Heroku recently announced support for Active Storage in Rails 5.2, which introduces the ability to generate previews of PDFs and videos. As a security engineer, hearing about a new feature in a product that automatically parses media files definitely grabbed my attention. This post takes a look at...
