Requiring AWS IAM Users to Enable MFA

When AWS announced Lambda at the 2014 re:Invent, my immediate thought was “Cool, you can now program the cloud itself”. Since then, everyone has jumped on the “serverless” bandwagon for building apps. After this year’s re:Invent I’m inspired to get back to using Lambda to program the cloud.

One of the sessions I attended was on Security Automation. I’ll have more to say on that later. However, it gave me the idea for a setup that would require users to have MFA enabled, or otherwise be blocked from doing anything with their IAM User in the AWS account.

Turner’s Presentation at re:Invent 2016

My VP, Michael Koetter, gave a presentation in the Media Track at re:Invent on the AWS-based Content Supply Chain we’re building. You can check it out here: Plus a Link to SlideShare.net where you can see one of my diagrams: http://www.slideshare.net/AmazonWebServices/aws-reinvent-2016-turners-cloud-native-media-supply-chain-for-tnt-tbs-adult-swim-cartoon-network-cnn-mae302

AWS API Keys in OSX Keychain

AWS API Keys are powerful things that you don’t want to leave lying around. Amazon’s suggestion is to keep them in ~/.aws/config. I’m not a fan of that. OSX has KeyChain, which is a secure repository for credentials and what most OSX Apps use for caching your login to various websites. This might not be the ideal solution, but it’s better than an unencrypted file in your home directory.

I’ve built a set of three scripts that will use OSX Keychain to store your AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY, and retrieve them into environment variables when needed to use the AWS API or any script that honors those environment variables.

AWS New Account Config

We’re getting ready to deploy our first production workload in AWS, and our AWS account team recommended we enable a bunch of auditing on our accounts in each region. That is a lot of clicking for 9 regions across three accounts. This script will configure AWS CloudTrail and AWS Config Service in all regions, configure the logging bucket, and establish a reasonable password policy. Amazon is about to release 3 (or four) more regions in Ohio, England, Korea and India.

The Rumors of my demise….

… are not that exaggerated. I have a three year old, I have a job that discourages political blogging. I’m not doing that much that is interesting. Except that I am doing cool shit at work and I should be more willing to talk about it. So I will start posting here more. The first bit of news is that I’ve stuck a stake in the heart of Prime Harbor, and I’m no redirecting that site here.
