Three multi-tenant isolation boundaries of Kubernetes

Many of the benefits of running Kubernetes come from the efficiencies that you get when you share the cluster – and thus the underlying compute and network resources it manages – between multiple services and teams within your organization. Each of these major services or teams that share the cluster are tenants of the cluster – and thus this approach is referred to as multi-tenancy.

Escaping a Docker container

Escaping a docker container can get you access to the whole linux host, so it's a precious technique for a cyber attack. But it's also valuable for defenders: hacking docker containers to get a breakout is a fun way to better understand a vulnerability and how to better protect from these exploits! In this hands on video, we look at three real life scenarios where you can actually break out from a docker container.

Using Sysdig Secure to Detect and Prioritize Mitigation of CVE 2022-3602 & CVE 2022-3786: OpenSSL 3.0.7

The awaited OpenSSL 3.0.7 patch was released on Nov. 1. The OpenSSL Project team announced two HIGH severity vulnerabilities (CVE-2022-3602, CVE-2022-3786), which affect all OpenSSL v3 versions up to 3.0.6. These vulnerabilities are remediated in version 3.0.7, which was released Nov. 1. The vulnerabilities fixed include two stack-based buffer overflows in the name constraint checking portion of X.509 certificate verification.

How to deal with ransomware on Azure

Let’s dig deeper into the techniques used by attackers and the mitigations you should implement when ransomware on Azure affects you. By now, we should all be aware of ransomware from the constant news articles associated with this known threat. As we explained in the anatomy of a cloud attacks, ransomware is a way for attackers to make money when they gain control of your accounts through data encryption, therefore restricting your access to the system.

3 container security best practices to strengthen your overall security posture

Container environments are highly dynamic and require continuous monitoring, observability, and security. Since container security is a continuous practice, it should be fully integrated into the entire development and deployment cycle. Implementing security as an integral part of this cycle allows you to mitigate risk and reduce the number of vulnerabilities across the dynamic and complex attack surface containers present.

A Simple Overview of Authentication Methods for Kubernetes Clusters

Kubernetes is a very complex product where creating and managing clusters requires a great deal of knowledge on a wide range of topics. The introduction of managed clusters brought simplicity to the process allowing users to focus on extracting the most out of the system. One of the areas of most interest and different configurations is authentication and authorization. In authentication, the main objective, and most critical of all, is to ensure the identity and validity of users and machines.

Teleport Kubernetes Demo | Setup, RBAC, Event Auditing

In this video, we'll look at how to manage Kubernetes access with Teleport. We'll set up a Teleport cluster, securely add a Kubernetes cluster to be managed in Teleport, do a deep dive on controlling access to Kubernetes with Teleport's RBAC system, and end with an overview of Teleport's built-in auditing capabilities.

Multi-Cloud Kubernetes Backup and Any2Cloud Recovery at KubeCon NA 2022

With over 300 vendors exhibiting at KubeCon + CloudNativeCon North America 2022 (which is the long and official conference name), there was no shortage of early-stage vendors (230 at the silver and startup sponsor level) to visit for the 7000 attendees. Observability and security solutions were popular for the early-stage exhibitors.

Does cloud log management shield you from threats? CloudTrail vs CloudWatch

What is different about cloud log management versus on-premises? The answer may seem simple, but several elements such as CloudTrail vs. CloudWatch come into play. In this article, we will cover some of the most important differences, and then dig deeper into a specific example of AWS CloudTrail vs. CloudWatch.
