Container escapes have become a popular attack with the rise in container deployments. We show you how to harden the underlying infrastructure to keep your applications and host system secure.
The certigo utility checks the certificate chain, and the command-line output tells you who issued which certificates when, pointing out any ambiguities.
Centralized logging for today's large scalable platforms is a challenge, especially if Kubernetes is involved. Loki, Grafana, SeaweedFS, and the LogQL query language promise a solution that avoids heavyweight tools.
The open source Graylog platform enables centralized log management across system, application, and network boundaries by collecting logs centrally, analyzing them in real time, and detecting errors and security incidents at an early stage.
An ephemeral communication approach promises a solution to the persistent lifecycle of sensitive data by resorting to messages that self-destruct after being read.
Quality-of-service systems help prioritize scarce resources and keep critical services running with efficient bandwidth management.
Docker Swarm and Kubernetes both orchestrate container clusters, manage workloads, improve reliability, and automate the operation of distributed applications, but they are based on different architectures. We compare the two platforms, highlighting their benefits and downsides.
