Docker Zombie Layers are unreferenced image layers that continue to exist for weeks in registries, even after being removed from a manifest. In this hands-on deep dive, we explore how these layers can persist in registries and why ensuring the immediate revocation of exposed secrets is critical.

Container security involves protecting containerized environments and the applications they run. As containers package applications and their dependencies, they offer consistency across different environments. However, this also raises security concerns, such as ensuring the integrity of container images, securing the runtime environment, and managing vulnerabilities in container engines and orchestrators.

Recently, AWS expanded the scope of their AWSCompromisedKeyQuarantine policies (v2 and v3) to include new actions. This policy is used by AWS to lock down access keys that they suspect have been compromised. A common example of this process in action is when AWS automatically applies the quarantine policy to any keys found by scanning public GitHub repositories. This proactive protection mechanism can stop compromises before they happen.

Teleport provides a secure and scalable solution for managing namespace separation in Kubernetes clusters, streamlining compliance, and enabling financial institutions to maintain both resiliency and agility. Kubernetes has rapidly evolved from a tech buzzword to an indispensable backbone of modern infrastructure in the financial services industry — redefining how institutions scale, secure, and deliver their most critical applications.

Recently, Sysdig published a blog post about the ways businesses can harden their LLM-based AI applications using the OWASP Top 10 for Large Language Models. So why are we writing about MITRE ATLAS, and how is this any different from the OWASP Top 10 for LLMs?

On September 26th, 2024, details were released about several vulnerabilities in the Common Unix Printing System (CUPS) package. A total of four CVE’s (CVE-2024-47176, CVE-2024-47076, CVE-2024-47175, and CVE-2024-47177) have been released, affecting many Unix and Linux distributions. Three of the vulnerabilities are rated High, while one is rated Critical. If left unpatched, a remote attacker is able to execute arbitrary commands on the affected system.

Cloud attackers are swift and sophisticated, requiring robust threat detection and response programs that can keep pace with these malicious actors born in the cloud. They exploit the automation and scale of the cloud, along with new techniques, to accelerate all stages of an attack and inflict damage within minutes.

The European Union (EU) is leading the development of comprehensive cybersecurity regulations. These frameworks shape secure digital environments and protect businesses and citizens from cyber threats. For industry leaders and cybersecurity practitioners, especially those focused on cloud technologies, understanding and navigating these frameworks is key to maintaining compliance and gaining a competitive edge.

Disruptive technologies have a learning curve in the pace of adoption and implementation. Training and education tend to follow a slower schedule and can have a hard time keeping up with discoveries happening on the bleeding edge. This is part of what led to the current cloud security skill gap. The cloud transformed software development, accelerating innovation and the pace of human creativity. But, we now know that it also formed new security challenges.
