There are many reasons to choose Heroku Data services, but keeping the services you use secure and up-to-date rank near the top. This foundation of trust is the most important commitment we make to our customers, and frequent and timely maintenances are one way we deliver on this promise.

We do everything we can to minimize downtime, which is typically between 10 – 60 seconds per maintenance. There are ways for you to minimize disruption too (see the tips and tricks below). The rest of the post explains how we think about Heroku Data maintenances, how we perform them, and when we perform them.

Hackers exploit known but unpatched vulnerabilities or out-of-date...

There’s obviously more to security than humans, technology, and vendors with all of their implementations and expertise. At Heroku we believe that security is a byproduct of excellence in engineering.

All too often, software is written solely with the happy path in mind, and security assurances of that software has its own dangerous assumptions. A mature security program should challenge assumptions of security controls, move to testing continuously, and prepare for the unexpectable.

This means asking hard questions about the bigger picture. Think bigger than the development lifecycle, backing away from the fixations of confirming effective corrections and remediations. This means taking...

This blog post is adapted from a talk given by Joe Kutner at Devoxx 2018 titled "10 Mistakes Hackers Want You to Make."

Building self-defending applications and services is no longer aspirational--it’s required. Applying security patches, handling passwords correctly, sanitizing inputs, and properly encoding output is now table stakes. Our attackers keep getting better, and so must we.

In this blog post, we'll take a look at several commonly overlooked ways to secure your web apps. Many of the examples provided will be specific to Java, but any modern programming language will have equivalent tactics.

1. Ensure dependencies are up-to-date

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.

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.
