Assessing compliance with AWS Audit Manager

Introduction As in traditional IT infrastructures, firms in regulated industries such as banks or energy providers have strict security requirements to comply with when using public cloud providers as well. However, cloud adoption is often driven by application development teams that are striving for increased speed and agility to launch new features in their application, but don’t care too much about those regulatory requirements. That makes it particularly important for IT governance functions to have effective tools to evaluate compliance with the aforementioned standards and gather evidence that can be provided to their internal or external auditors.

(Prevent) Hacking into a CloudService - About security, ECS and terraform AWS UserGroup Hannover Online Meetup Feb, 4th 2021

Yoni: Oftentimes, when we think about protecting resources in the cloud, we immediately think about the typical ways in - via public-facing applications or abuse of credentials. In this talk, we will look at one additional way: through the work unit parameters of a service. During the development of Indeni’s Cloudrail SaaS product, Yoni was responsible for trying to find ways to hack into the service. One of the ways he found, raises questions about how secure ECS workloads really are.

Air-Gapped Compliance Scans with InSpec

Chef InSpec offers the possibility to scan any type of device using community-authored compliance profiles. As InSpec needs to connect to the machines, networking and firewall rules make this task tricky in bigger environments.

Rotate your credentials and don't forget MFA

According to the Well-Architected Framework and the least privileges principle, you should change your access keys and login password regularly. Therefore the user should have the right to edit their credentials. But only their own. Also using MFA - multi-factor authentication enhances the security even more. Therefore the user should be able to change MFA. But only their own. But how to do that? You have to combine two parts of AWS documentation. We will show you how you provide a “self-editing” group for your users with the CDK.

Three hurdles to skip before using the secure Instance Metadata Service V2

Do not use new Instance Metadata Service V2 (imdsv2) without proper prevention! You may think you can use Instance Metadata Service V2 right away, but there are a few caveats: Many old modules do not work with imdsv2 yet. We look at aws cli, the Systems Manager agent and the Instance Connect service. Currently, these services will not work with imdsv2 on an EC2 instance with the latest Amazon Linux 2 image out of the box. Here you can read how to make them work!

Defenders - caller based EC2 security with CDK

Defenders: Caller based EC2 security The risk with security credentials is that they get exposed an are being used elsewhere. What if we could prevent that the are being used elsewhere. The idea from the article of William Bengston from netflix was: Dynamically locking credentials to the environment. This implementation of this idea is much more simple with the cdk. So, let’s defend ourselves! Our story here is the battle of the defenders (tm).
