Detecting Manual AWS Console Actions
In this post I’ll describe a set of AWS Cloudtrail alerting rules that let you detect when someone makes a manual change in your AWS Console. This has been one of the highest signal / lowest noise alerts we created in our organization - it lets us know when engineers do things like, i.e., manually add new security group ingress rules through the AWS Console

WeirdAAL (AWS Attack Library) Basics from the Authors - The Ethical Hacker Network
WeirdAAL has two goals related to the AWS keys you find, procure, or need to test. First, answer the “what can I do with this AWS key pair” from a blackbox perspective. Secondly, be a repository of useful functions, both offensive and defensive, to interact with AWS Services. This article is meant to be a basic tutorial to get you started.

cloud-custodian/cloud-custodian: Rules engine for cloud security, cost optimization, and governance, DSL in yaml for policies to query, filter, and take actions on resources
Custodian can be used to manage AWS, Azure, and GCP environments by ensuring real time compliance to security policies (like encryption and access requirements), tag policies, and cost management via garbage collection of unused resources and off-hours resource management.

Custodian policies are written in simple YAML configuration files that enable users to specify policies on a resource type (EC2, ASG, Redshift, CosmosDB, PubSub Topic) and are constructed from a vocabulary of filters and actions.

It integrates with the cloud native serverless capabilities of each provider to provide for real time enforcement of policies with builtin provisioning. Or it can be run as a simple cron job on a server to execute against large existing fleets.

detecting domain hijacking.
verifying security services such as Cloudtrail and VPC Flowlogs.
managing IAM policies across multiple accounts.

StreamAlert — streamalert 2.2.0 documentation
StreamAlert is a serverless, real-time data analysis framework which empowers you to ingest, analyze, and alert on data from any environment, using data sources and alerting logic you define. Computer security teams use StreamAlert to scan terabytes of log data every day for incident detection and response.
Overview

Incoming log data is classified and scanned by the StreamAlert rules engine running in your AWS account. Rule matches are reported to one or more alert outputs:

Productionproofing EKS – Glia Tech – Medium
We recently migrated SaleMove infrastructure from self-managed Kubernetes clusters running on AWS to using Amazon Elastic Container Service for Kubernetes (EKS). There were many surprises along the way to getting our EKS setup ready for production. This post covers some of these gotchas (others may already be fixed or are not likely to be relevant for a larger crowd) and is meant to be used as a reference when thinking of running EKS in production.

Serverless Microservice Patterns for AWS - Jeremy Daly
I’ve read a lot of posts that mention serverless microservices, but they often don’t go into much detail. I feel like that can leave people confused and make it harder for them to implement their own solutions. Since I work with serverless microservices all the time, I figured I’d compile a list of design patterns and how to implement them in AWS. I came up with 19 of them, though I’m sure there are plenty more.

CloudCopy — Stealing hashes from Domain Controllers in the Cloud
CloudCopy is an attack I developed for performing the Shadow Copy abuse within AWS. What sets this apart from the original attack, other than being in the cloud, is that it requires far lower permissions to execute and does not require any commands to be run against the target instance. If an attacker possesses the CreateSnapshot and ModifySnapshotAttribute permissions, they can create a snapshot of a running instance, mount it to a separate attacker controlled instance, and browse its contents without authentication.

AWS Elastic Beanstalk – Deploy Web Applications
You can simply upload your code and Elastic Beanstalk automatically handles the deployment, from capacity provisioning, load balancing, auto-scaling to application health monitoring. At the same time, you retain full control over the AWS resources powering your application and can access the underlying resources at any time.

There is no additional charge for Elastic Beanstalk - you pay only for the AWS resources needed to store and run your applications.

AWS Fargate - Run containers without having to manage servers or clusters
AWS Fargate seamlessly integrates with Amazon ECS. You just define your application as you do for Amazon ECS. You package your application into task definitions, specify the CPU and memory needed, define the networking and IAM policies that each container needs, and upload everything to Amazon ECS. After everything is setup, AWS Fargate launches and manages your containers for you.

GitHub - Netflix/bless: Repository for BLESS, an SSH Certificate Authority that runs as a AWS Lambda function
BLESS is an SSH Certificate Authority that runs as an AWS Lambda function and is used to sign SSH public keys.

SSH Certificates are an excellent way to authorize users to access a particular SSH host, as they can be restricted for a single use case, and can be short lived. Instead of managing the authorized_keys of a host, or controlling who has access to SSH Private Keys, hosts just need to be configured to trust an SSH CA.

flAWS2.cloud
flAWS 2 has two paths this time: Attacker and Defender! In the Attacker path, you'll exploit your way through misconfigurations in serverless (Lambda) and containers (ECS Fargate). In the Defender path, that target is now viewed as the victim and you'll work as an incident responder for that same app, understanding how an attack happened. You'll get access to logs of a previous successful attack. As a Defender you'll learn the power of jq in analyzing logs, and instructions on how to set up Athena in your own environment.

SANS Institute: Reading Room - Cloud Computing
Companies using AWS (Amazon Web Services) will find that traditional means of full packet capture using span ports is not possible. As defined in the AWS Service Level Agreement, Amazon runs certain aspects of the cloud platform and does not give customers access to physical networking hardware. Although access to physical network equipment is limited, packet capture is still possible on AWS but needs to be architected in a different way.

You can host a static website on Amazon Simple Storage Service (Amazon S3). On a static website, individual webpages include static content. They might also contain client-side scripts. By contrast, a dynamic website relies on server-side processing, including server-side scripts such as PHP, JSP, or ASP.NET. Amazon S3 does not support server-side scripting. Amazon Web Services (AWS) also has resources for hosting dynamic websites. To learn more about website hosting on AWS, go to Websites and Website Hosting.

Hiding Secrets in Terraform
Unfortunately, in order to set up most of these services you need usernames and passwords to be set - and since you can potentially change these passwords via Terraform then it stands to reason that Terraform is going to need be able to compare your old credentials with possible new ones.

To facilitate this it stores all settings, including usernames, passwords, port numbers and literally everything else in these tfstate files, in plain text.

This wasn’t something I’d have expected as the default behaviour. The documentation does suggest that you use a thing called Remote State (more on that later)
