In today’s digital landscape, cyber threats continue to evolve at an alarming pace, with hackers constantly finding new ways to infiltrate systems and compromise sensitive data. One such sophisticated threat is fileless malware, a stealthy form of malicious software that operates entirely in the computer’s memory without leaving any trace on the hard drive.
In a previous blog post, Hands-on guide: How to scan and block container images to mitigate SBOM attacks, we looked at how Software Supply Chain threats can be identified and assessed. The severity of these vulnerabilities determine the posture or scan result for an image i.e. Pass, Warning or Fail. The next question is “What can we do with these results?”.
In this article, you will learn about how to achieve high-throughput, real-time authorization. You should gain a basic understanding of the different protocols for interacting with the Open Policy Agent (OPA) and Styra Enterprise OPA APIs, as well as how and when to use different options. We will also cover the strengths of different protocol choices, and where they may make sense in your system architecture.
Microservices security is a growing concern for businesses in the face of increasing cyber threats. With application layer attacks being a leading cause of breaches, it’s more important than ever to safeguard the HTTP-based communication between microservices within a Kubernetes cluster. Traditional web application firewalls (WAFs) are not designed to address this specific challenge, but Calico WAF offers a unique solution.
Two web-scale companies have recently shared how they solved mission-critical authorization challenges using Open Policy Agent (OPA). These accounts validate the value of what we’ve built with OPA and give important blueprints for engineers looking to address similar challenges. We consider these required reading for anyone considering or using OPA at scale. In this post we review these two case studies to highlight common patterns and important differences.
Velero is an open-source backup and recovery tool designed specifically for Kubernetes clusters. It provides a straightforward way to protect your Kubernetes resources, including persistent volumes, namespaces, and custom resources, by taking backups and restoring them in case of data loss or disaster recovery scenarios. In this blog you will learn the different use cases for Velero and the two ways to install Velero, using the Velero CLI and using a Helm chart.
Relying solely on the Common Vulnerability Scoring System (CVSS) is insufficient when it comes to effective vulnerability management. While the CVSS score provides a quantitative measure of a vulnerability’s severity, it fails to capture the contextual nuances that can significantly impact the actual risk to an organization. In this article, we will discuss how best to choose a vulnerability management solution.
SCARLETEEL, an operation reported on by the Sysdig Threat Research Team last February, continues to thrive, improve tactics, and steal proprietary data. Cloud environments are still their primary target, but the tools and techniques used have adapted to bypass new security measures, along with a more resilient and stealthy command and control architecture.
