The Payment Card Industry Data Security Standard (PCI DSS) entered the scene back in 2004 with the rise of payment fraud. Created by leaders in the credit card industry, PCI DSS was developed to provide a baseline of technical and operational requirements designed to protect cardholder payment data and was commonly understood by those in the legacy security world.
Last week, a critical vulnerability identified as CVE-2022-0185 was disclosed, affecting Linux kernel versions 5.1 to 5.16.1. The security vulnerability is an integer underflow in the Filesystem Context module that allows a local attacker to run arbitrary code in the context of the kernel, thus leading to privilege escalation, container environment escape, or denial of service.
A container is defined as packaged software that contains all the code and dependencies of an application within a virtual environment so that the application can be migrated from any computing device to another. Docker container images are executable software packages that are lightweight and standalone.
Cryptocurrency mining has become very popular among malicious actors that aim to profit by exploiting cloud attack surfaces. Exposed Docker APIs have become a common target for cryptominers to mine various cryptocurrencies. According to the Google Threat Horizon report published Nov. 29, 2021, 86% of compromised Google Cloud instances were used to perform cryptocurrency mining.
Before we talk about design patterns for Open Policy Agent (OPA) (what they are, why they’re beneficial, what their key ideas are, and how you might try to see them in action with sample data/apps in Styra Declarative Authorization Service (DAS) Free), it’s helpful to start with some background. When we designed the OPA at Styra, we aimed to make it flexible enough to solve every authorization and policy problem in the cloud-native space (and beyond).
The fifth annual Sysdig Cloud-Native Security and Usage Report digs into how Sysdig customers of all sizes and industries are using and securing cloud and container environments. We examined the data and found some interesting trends this year that may help you as you work to develop best practices for securing and monitoring your cloud-native environments. This year’s report has new data on cloud security, container vulnerabilities, and Kubernetes capacity planning.
Kubernetes is the popular container orchestration platform developed by Google to manage large-scale containerized applications. Kubernetes manages microservices applications over a distributed cluster of nodes. It is very resilient and supports scaling, rollback, zero downtime, and self-healing containers. The primary aim of Kubernetes is to mask the complexity of overseeing a large fleet of containers.
Are you wondering how to secure your Kubernetes clusters? Do you even know whether your Kubernetes is secure? Kubescape by ARMO might be the tool to help you with those and many other tasks related to Kubernetes security and scanning. Check this video by Viktor Farcic from DevOps Toolkit on Kubescape as he covers the 3 main K8s security areas – While reducing the number of false positives to a minimum and getting help fixing issues.
In the last few days, Linux maintainers disclosed a broadly available Linux kernel vulnerability that enables attackers to escape containers and get full control over the node. To be able to exploit this vulnerability, the attacker needs to be able to run code in the container and the container must have CAP_SYS_ADMIN privileges. Linux kernel and all major distro maintainers have released patches.
