Container Support in Pulsar
Our Rust Engineer, Michal Rostecki, recently discussed about how Pulsar supports containers and enhances their security. This blog post is a simplified overview of his talk.
Pulsar is an open-source project that stands out for people looking for a strong security observability framework. It was first made for IoT devices, but because of its flexible rule language and complete default rule set, it can be used more widely. This flexibility lets users make custom rules based on Pulsar's specific event hooks, making it useful beyond just IoT devices.
Michal's presentation introduces Pulsar's features, focusing on its ability to protect container workloads. He explains the importance of Pulsar's rule system and engine, which allow users to set up custom security policies for their specific operations. Through hands-on examples, Michal shows how Pulsar uses the Linux kernel's eBPF technology to track and respond to different system events, from process activities to network operations.
A key point in the presentation is the new container support in Pulsar, a big step for the project. This feature lets Pulsar monitor processes in containers, improving security in environments using containers. Michal gives information on how Pulsar can track events from containers, adding extra details like image URIs and checksums. This improvement makes it easier to create rules which target container workloads and even specific containers (recognized by their images).
Additionally, Michal discusses usual threats to containers like escape attempts and unauthorized access to host resources. He shows how Pulsar's advanced rules can identify and stop these threats early, highlighting Pulsar's effectiveness in keeping containerized environments safe.
