CloudTrail Data Events

In today’s post, I will talk about a hacking investigation I recently took part in. We will look into what went wrong, what the attackers did, and how we can improve detection and prevention to manage such incidents better.

Map out your IAM with PMapper

Writing “Least Privilege” policies is an art in itself, but it inevitably leads to a large number of JSON-based policies in your accounts. As one of the rules of good security is “low maintainability = low security”, let’s dive into tools which can show us risks inside our policies - which might even result in paths to administrative privileges!

Secure Backup Solution for OnPremises and Hybrid Environments

With current ransomware attacks it is important to have a reliable backup strategie in place.

Least Privilege - Semi-Automated

In almost every tutorial on AWS you will come across the term “Least Privilege”. Writing IAM policies properly requires lots of research and time - that’s the reason why many projects still rely on AWS Managed Policies or write exploitable policies. But there are tools to help you along.

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. With the newly released train-awsssm plugin, this situation changes drastically. Read on, if you want to know how.

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.
