Container security

Container security is an IT practice that is focused on safeguarding containers and their applications against security threats. Organizations can gain visibility into the usage of both containers and the applications they contain by implementing robust security measures in such an environment.

Containers offer lightweight, isolated environments with application code, runtime, and dependencies. They are widely used to deploy and scale applications both on-premises and in the cloud. As container applications and infrastructure become more popular, it becomes essential to protect them from potential threats.

Wazuh for container security

Wazuh integrates with container platforms like Docker and Kubernetes and actively monitors container runtime events, application logs, and overall container health. Wazuh identifies anomalies by evaluating container logs against predefined rules. Additionally, it maintains a record of container engine actions to detect unauthorized activities in a containerized environment. It also monitors health metrics to prevent performance bottlenecks in an organization.

Wazuh container security features comprise monitoring container runtimes, tracking containerized application logs, monitoring container resource utilization, centralized logging, and container alert notifications. This comprehensive set of capabilities enhances security and streamlines incident response.

Container runtime monitoring

Organizations can enhance the security of their containerized applications by monitoring container events. They can proactively address unexpected behavior by promptly responding to alerts triggered by predefined rules. Wazuh also provides insight into container engine interactions and detects irregularities in containerized applications.

Monitoring the container engine

Wazuh captures real-time events performed by the Docker engine via its Docker listener module. This ensures that no crucial Docker event or operation goes undetected.

Monitoring user interaction with Docker resources demonstrates how Wazuh enhances visibility into the interactions of the container engine with the containers and the images.

Monitoring containerized application logs

Wazuh allows organizations to monitor containerized applications. It provides visibility into the applications that are resident in the container. When the application events are forwarded to the Wazuh manager, Security engineers can create custom rules that align with the unique requirements of their organization. This facilitates a highly personalized approach that improves overall visibility into the containers and the applications they host.

The Monitoring container runtime documentation has more information about monitoring containerized application logs.

Monitor container resource utilization with Wazuh

Wazuh tracks and analyzes the resource consumption of containerized applications. It provides insights into the CPU, memory, and network usage statistics of containers, assisting in identifying performance bottlenecks.

Wazuh provides customizable alerts and notifications, enabling organizations to detect and proactively respond to unusual resource spikes or consumption patterns.

The blog post on Docker container security monitoring with Wazuh demonstrates how Wazuh monitors network utilization in a containerized environment.

Centralized logging and visualization of containers event

Wazuh centralizes container event logging and visualization. Its scalable indexer aggregates logs into a powerful search and analytics engine, providing real-time insights. This indexer handles event influx while also supporting compliance needs such as log retention policies.

Wazuh enables organizations to view container logs from a customized dashboard. Security professionals can track and analyze unfolding activities, swiftly identifying threats and unauthorized actions. This early detection enables security professionals to respond to security incidents as they arise swiftly, establishing an active approach to minimizing risks.

The image below displays the customized container dashboard of Wazuh, where events from all containers are showcased.

Container alert notification with Wazuh

Wazuh integrates with messaging platforms like email and Slack. It also integrates with case management solutions, like Jira , for incident response and real-time alerting. This ensures that security teams are promptly notified whenever potential threats or unauthorized actions occur in containerized environments.

The documentation on Integration with third-party APIs explains how the Integrator daemon allows Wazuh to connect to external APIs and case management systems tools like PagerDuty.
