Background for this topic.
Containers package software and its dependencies into isolated units that run consistently across environments. They share the host operating system kernel but maintain separation through namespaces and control groups, enabling efficient resource use and rapid deployment. This isolation differs from full virtual machines by being more lightweight and portable.
Security concerns focus on container escape, where vulnerabilities allow attackers to break isolation and access the host system or other containers. Risks also arise from untrusted or outdated container images that may contain malware or vulnerabilities. Defenses include image scanning, minimal base images, runtime security monitoring, and strict access controls on container orchestration platforms to limit privilege escalation and lateral movement within containerized environments.
