Scope of Kubernetes Security

In cloud-native security, the term “Kubernetes Security,” is used to describe a wide range of capabilities. For example, it could be used to describe a niche cloud-native security vendor focused only on runtime or a tool that deals specifically with Kubernetes configurations. Both of these descriptions would be accurate because Kubernetes reaches far across the network, cloud, CI/CD process, and identity, as well as having its own unique set of security requirements.

Roles of Kubernetes in Cloud-Native Applications

Kubernetes has redefined the way organizations build, deploy, and manage applications at scale, offering a robust platform that caters to the diverse and dynamic demands of cloud-native environments. From automating deployment processes to managing complex workloads, Kubernetes provides a comprehensive solution that addresses several key challenges associated with cloud-native applications:

  • Container Orchestration: At its core, Kubernetes efficiently manages containerized applications, ensuring they are deployed, scaled, and operated in a consistent and automated manner.
  • Scalability: Kubernetes excels in enabling applications to scale seamlessly in response to varying loads, optimizing resource utilization and performance.
  • High Availability: With features like self-healing, load balancing, and rolling updates, Kubernetes enhances the availability and resilience of applications, minimizing downtime and ensuring continuous operation.
  • Service Discovery and Load Balancing: Kubernetes simplifies the process of connecting and balancing loads among different application components, thereby optimizing resource allocation and user experience.
  • Automated Rollouts and Rollbacks: It provides mechanisms for automated updates and rollbacks, enabling agile and secure deployment practices.
  • Storage Orchestration: Kubernetes streamlines storage orchestration, allowing applications to automatically mount the storage system of choice, whether from local storage, public cloud providers, or network storage systems.
  • Secret and Configuration Management: It securely manages sensitive information such as passwords, OAuth tokens, and SSH keys, making it easier to deploy and update application configurations without rebuilding container images.

Who is Responsible for Kubernetes Security?

Depending on the size of an organization, responsibility for Kubernetes security is oftentimes shared among several roles and/or teams, each contributing to different aspects of securing the Kubernetes environment.

Common roles involved in Kubernetes security include:

  • DevOps Teams may be responsible for implementing and managing the deployment pipelines, ensuring security is integrated into the CI/CD process.
  • Infrastructure Security Engineers may be tasked with protecting the underlying infrastructure that supports Kubernetes clusters.
  • IT Security Teams may oversee the IT infrastructure, which includes Kubernetes clusters. They may define policies, conduct security audits, and respond to security incidents.
  • Chief Information Security Officers - CISOs Play a strategic role in overseeing the overall security posture of the organization, including Kubernetes environments. They are responsible for setting security policies, ensuring compliance with regulations, and guiding the organization in responding to emerging security threats.
  • Cloud Security Teams are focused specifically on securing cloud-based resources, including Kubernetes clusters hosted on the cloud. They may be responsible for securing the cloud infrastructure, network configurations, and access controls.
  • SREs (Site Reliability Engineers) may ensure Kubernetes clusters are set up correctly and securely, monitoring the clusters' health and performance, and applying patches and updates.
  • Security Architects design and oversee the implementation of a comprehensive security framework for Kubernetes environments.
  • Compliance and Risk Management Teams ensure that Kubernetes deployments comply with relevant regulations and standards. They are responsible for risk assessments and compliance audits.

In practice, Kubernetes security is a collaborative effort that requires coordination and communication among various teams and roles (DevSecOps). An organization needs to establish clear policies, provide proper training, and ensure that all stakeholders are aware of their responsibilities in maintaining the security of the Kubernetes environment.

 

Understanding Kubernetes Architecture

Understanding the architecture of Kubernetes is fundamental to securing it. This section outlines the basic architectural components of Kubernetes, their default configurations, and their lifecycle. By comprehending how these elements interconnect and operate, you can identify potential security vulnerabilities and implement effective safeguards.

Kubernetes Architecture Basics

At the heart of Kubernetes' ability to manage containerized applications at scale is its distinctive and dynamic architecture. We will explore the core elements of this architecture, starting from the smallest unit, the Pod, to the broader constructs such as Nodes, Clusters, and the Control Plane. Each of these components plays a pivotal role in the orchestration and operation of containerized applications, and understanding their functions and interactions is key to both maximizing the efficiency of Kubernetes and securing its environments.

  • Pods and Nodes: Pods are the smallest deployable units in Kubernetes, housing one or more containers. Nodes are worker machines in Kubernetes, which can be physical or virtual machines, where pods are scheduled and run.
  • Clusters: A cluster is a set of nodes that run containerized applications. It includes at least one worker node and a control plane, which orchestrates container workloads.
  • Control Plane Components: The control plane's components, including the kube-apiserver, kube-scheduler, kube-controller-manager, and cloud-controller-manager, manage the state of the cluster.
  • Default Configurations: Many Kubernetes installations come with default configurations that may not be secure. It's crucial to review and adjust these settings to enhance security. (Refer to Preventing Misconfigurations for more details).

Lifecycle Management

Lifecycle management refers to the process of managing the lifecycle of resources within a Kubernetes cluster. This usually involves activities including initialization, scaling, monitoring, maintenance, patching, backups, disaster recovery, decommissioning, and cleanup.

→ Overview of the Kubernetes Deployment Lifecycle

 

Kubernetes Security Best Practices 

There are many best practices guides available in the industry around Kubernetes security, for example the Kubernetes OWASP Top 10, DISA, NIST and the CIS benchmarks.

Both the Center for Internet Security (CIS) and the Defense Information Systems Agency (DISA) have published comprehensive container security benchmarks and recommended practices. These documents provide detailed guidance on configuring your Kubernetes environment and protecting it against potential threats. They also act as industry-wide security standards trusted and accepted by many organizations.

The National Institute of Standards and Technology (NIST) has released a Special Publication (SP) NIST 800-190 checklist – Application Container Security Guide to help organizations secure their containerized applications and related infrastructure components.

In response to the recent executive order on supply chain security, NIST released its NIST 800-161 standard. This framework was created with vigilance in mind, describing a secure software supply chain management system that enables organizations to guarantee the integrity of all software components. SP 800-161 provides specific guidance for safely developing and deploying containers, including detailed recommendations on leveraging efficient and secure DevOps processes. KSOC has released the first Kubernetes Bill of Materials (KBOM) standard to help teams incorporate Kubernetes into their efforts around software supply chain security. To contribute, visit our Github repo.

In general, best practices include container security, hardening Kubernetes itself, runtime security, and if Kubernetes is deployed by a cloud managed service.

Kubernetes Security Best Practices for Managed Cloud Providers

There are also best practices involved for securing the Kubernetes managed cloud providers like EKS, AKS and GKE. For example, 

To secure your resources, you should consider using AWS security groups and network ACLs to limit access to specific ports. Additionally, enabling logging and audit trails will aid you in detecting any suspicious activity.

EKS multi-tenancy best practices are often considered when deploying multiple applications onto the same cluster. This typically involves setting resource limits for each application and ensuring network security between tenants.

Finally, data encryption and secrets management should be implemented for your Kubernetes clusters. This includes using encryption at rest and in transit and configuring Kubernetes secrets to securely store sensitive information. Following these AWS Kubernetes security best practices will make your container environment more secure and protected from potential threats.

In AKS, for example, you should use the Azure Kubernetes Service security features such as Transport Layer Security (TLS) and Pod Security Policies to ensure that traffic between services is encrypted and secure. Finally, you should enable logging and audit trails to monitor activity on your cluster. This will ensure that you can detect suspicious behavior and act accordingly.

Understanding the Kubernetes Threat Landscape

As Kubernetes cements its position as the backbone of containerized application deployment, it's imperative to recognize and understand the myriad of threats that this complex ecosystem faces. The Kubernetes threat landscape is diverse and ever-evolving, presenting unique challenges that stem from both the inherent architecture of Kubernetes and the sophisticated nature of modern cyber threats.

Common Kubernetes Vulnerabilities

As Kubernetes continues to dominate the container orchestration landscape, understanding its vulnerabilities is paramount for maintaining robust security. 

  • API Server Vulnerabilities arise from misconfigured or unprotected API servers, leading to unauthorized access.
  • Container vulnerabilities are risks associated with container runtime environments, including container escape vulnerabilities.
  • Network exposures are threats stemming from inadequate network policies or misconfigurations that expose internal services to the public internet.

Emerging Threats in Kubernetes Ecosystem

In the rapidly evolving world of Kubernetes and cloud-native technologies, new threats emerge as quickly as the technologies themselves advance. In 2023 alone, there have been CVEs in third party plugins for Kubernetes that help with storage, admission control, managed providers, and more.

Kubernetes Security Tools & Capabilities

Kubernetes is a technology that reaches into the CI/CD pipeline in the application development lifecycle, deploys containers, and determines many of the conditions under which workloads run along with the services they utilize. As such, there is an enormous variety of tools used that classify themselves as Kubernetes Security, from vulnerability scanning tools to posture management, runtime, identity and detection and response tools.

KSPM

Kubernetes Security Posture Management (KSPM) focuses on the continuous assessment and improvement of the security posture of Kubernetes environments. It involves identifying misconfigurations, enforcing security best practices, and monitoring compliance with regulatory and organizational standards. An example of these misconfigurations could include:

  • Workloads that have been deployed with excessive privileges
  • Open Kubernetes API configuration
  • RBAC Misconfigurations

→ A Tool for Incident Response: KSPM Series Part II

→ Defense in Depth: KSPM Series Part III

 

CNAPP

Cloud-Native Application Protection Platform (CNAPP) is an emerging category coined by Gartner analysts to describe a solution that spans from image scanning prior to deployment through to runtime and also some CSPM element. There is no clear definition of the exact features that must be required to qualify as a CNAPP, but in general, it should have capabilities across the entire application development lifecycle. Various vendors will have various levels of integrations across those pieces. 

CWPP

A Cloud Workload Protection Platform (CWPP) is a security solution designed to protect workloads in cloud environments. This could include Endpoint Detection and Response (EDRs), XDRs as well, and might or might not secure containerized environments. The variety of what it secures includescontainers, serverless functions, and virtual machines.

SCA

Software Composition Analysis (SCA) involves scanning software components, especially open-source libraries and dependencies, for vulnerabilities. This is crucial in a Kubernetes environment where applications often rely on a mix of proprietary and open-source components.

KBOM

Kubernetes Bill of Materials (KBOM) is a detailed asset inventory or list of all components, libraries, and dependencies used in a Kubernetes application. This is helpful when trying to comply with the guidelines in the recent Biden Administration’s executive order, bringing Kubernetes into the picture, instead of just focusing on Software Bills of Material that are generated prior to deployment. A KBOM can help with vulnerability management, license compliance, and security audits.

→ KSOC releases the first Kubernetes Bill of Materials (KBOM) standard

Admission Control

Kubernetes admission control is an important enforcement capability that can block misconfigured workloads from deploying at the Kubernetes API level, per security policies. You can use pod security admission, pod security standards (formerly known as pod security policies), or any number of third party admission controllers like Kyverno or OPA.

Open Source

There are hundreds, if not thousands, of open source tools that offer observability, detection and response, logging, storage, and Kubernetes Security.  These solutions offer a community-driven method to filling the needs in the ecosystem for running, maintaining and securing Kubernetes environments. Here is an awesome list of Kubernetes security tools to get started.

Robust Configuration and Best Practices

Configuring Kubernetes securely is not just a one-time task but a continuous process of alignment with best practices and vigilance against evolving threats. In this critical section of the KSOC Kubernetes Security Master Guide, we delve into the nuances of robust Kubernetes configuration and the best practices that ensure a strong security posture.

→ Prerequisites To Implementing Kubernetes Security

Preventing Misconfigurations

Misconfigurations in Kubernetes environments are a leading cause of security breaches and operational issues.

These misconfigurations can arise from a variety of sources, including inadequate defaults, human errors, or a lack of understanding of Kubernetes' complexities. Preventing these misconfigurations is crucial for maintaining the security and stability of Kubernetes clusters.

Vulnerability Scanning

Vulnerability scanning in Kubernetes is a critical component of a robust security strategy, involving the identification of security weaknesses within the cluster. This process encompasses scanning container images, Kubernetes configurations, and RBAC configurations to detect vulnerabilities that could be exploited by attackers. A comprehensive scanning approach helps in early detection and remediation of security issues, thereby enhancing the overall security posture of Kubernetes deployments.

Types of Vulnerability Scanning

  • Container Image Scanning: Examining container images for known vulnerabilities before they are deployed.
  • Configuration Scanning: Assessing Kubernetes configuration files for potential misconfigurations or security risks (including RBAC).

Real-Time Vs. Log-Based Scanning

The methods of Kubernetes vulnerability scanning can generally be categorized into two types: Real-time scanning and log-based scanning. Each method has its distinct characteristics, advantages, and use cases. Understanding the differences between them is crucial for implementing an effective security strategy in Kubernetes environments.

Features of Real-Time Scanning via the K8s API

  • Immediate Detection: Real-time scanning continuously monitors Kubernetes clusters, identifying vulnerabilities as they occur. This immediacy is crucial for detecting and mitigating threats quickly.
  • Adaptability to Dynamic Environments: Kubernetes environments are highly dynamic, with containers frequently spinning up and down. Real-time scanning is adept at keeping pace with these changes, ensuring that short-lived containers are scanned before they terminate.
  • Proactive Security Posture: It enables a proactive approach to security, where potential threats are identified and addressed in real-time, often before they can be exploited.
  • Actionable Remediation: Real-time scanning provides instant feedback and actionable insights, allowing teams to respond to vulnerabilities swiftly and effectively.


Features of Log-Based Scanning (usually from cloud logs)

  • Historical Data Analysis: Log-based scanning involves analyzing historical logs to identify vulnerabilities. This approach is beneficial for understanding past security incidents and trends over time.
  • Delayed Detection: Unlike real-time scanning, log-based scanning does not provide immediate notification of vulnerabilities. This delay can be a significant drawback in environments where rapid response is critical.
  • Strategic Insights: By examining historical data, log-based scanning can offer valuable insights for strategic security planning and compliance reporting.
  • Trend and Pattern Recognition: It helps in recognizing patterns and trends in security threats, which can inform future security measures and policy development.

Network Security and Isolation

Kubernetes offers various mechanisms to manage network traffic, control how applications communicate, and enforce isolation between different parts of the system. Proper implementation of these mechanisms is essential to protect against unauthorized access and network attacks, ensuring the security and integrity of the applications running within Kubernetes clusters.

Implementing Network Policies

Network policies are crucial for defining rules that govern ingress and egress traffic between pods within a cluster. They allow administrators to control which pods can communicate with each other, effectively reducing the potential attack surface.

Pod-to-Pod Isolation

Pod-to-Pod isolation ensures that individual pods can interact securely and as intended within a cluster. This isolation is key to preventing unauthorized access and communication between pods, which can be crucial for maintaining the integrity and security of different applications or services running on the same cluster.

Control of Ingress and Egress Traffic

The control of ingress and egress traffic is essential for managing how external traffic accesses services within the cluster (ingress) and how services within the cluster reach external resources (egress). This control is pivotal for enforcing security policies, preventing unauthorized access, and ensuring that data flows in and out of the cluster securely.

Service Mesh Implementation

Implementing a service mesh serves to enhance application networking by providing a dedicated infrastructure layer for handling inter-service communication. This implementation facilitates more complex operational requirements like service discovery, load balancing, failure recovery, and metrics tracking without adding additional code within the service applications themselves.

Network Segmentation and Firewalls

Network segmentation and the use of firewalls are critical for creating secure network boundaries within the cluster. This approach divides the network into smaller segments or zones, each with its own unique set of security policies and controls. This segmentation is instrumental in minimizing the attack surface and containing potential breaches within isolated network segments.

DDoS Protection and Rate Limiting

The implementation of DDoS protection is crucial for safeguarding the cluster against volumetric attacks aimed at overwhelming and incapacitating services. By deploying DDoS protection strategies, Kubernetes environments can maintain availability and performance even under high-traffic conditions or attack scenarios.

Disaster Recovery and Data Backup

Disaster recovery and data backup provide a safety net against data loss and service interruptions, which can stem from various sources such as hardware failures, software bugs, or even cyber-attacks. This section will explore key strategies and practices for effective disaster recovery and data backup in Kubernetes environments.

Why Back Up Your Data?

Kubernetes, while robust, is not impervious to failures. The loss of data or service can be costly in terms of both time and resources. A comprehensive disaster recovery and data backup plan ensures business continuity, minimizes downtime, and safeguards critical data.

Disaster Recovery Strategies

  • High Availability Setup: Deploy Kubernetes clusters across multiple zones or regions. This ensures that if one zone goes down, the services can still run from another zone.
  • Cluster Replication: Replicate critical components of the Kubernetes cluster, such as the etcd database, across different geographical locations.
  • Failover and Failback Procedures: Establish clear procedures for failover to a backup system and failback to the primary system once the disaster is mitigated.
  • Infrastructure as Code (IaC): Use IaC tools for quick and consistent infrastructure provisioning, which is vital for rapid recovery.

Monitoring and Alerts

Implement a robust monitoring and alerting system to detect anomalies and potential threats early. See Vulnerability Scanning for more details.

Integrating Secure Application Development

Integrating security early in the development process helps in identifying and mitigating vulnerabilities before they escalate into major issues. It aligns with the DevSecOps approach, where security is a shared responsibility among developers, operations, and security teams.

Here are a few key strategies for secure development:

  • Secure Coding Practices: Educate and train developers in secure coding practices. This includes understanding common security pitfalls in coding and how to avoid them.
  • Dependency Management: Regularly scan and update dependencies to mitigate vulnerabilities.
  • Container Security: Secure container images by scanning for vulnerabilities and ensuring they are sourced from trusted registries. Implementing image signing and verification processes is also crucial.
  • Implementing Kubernetes-specific policies: Define and enforce security policies using Kubernetes-native controls like Pod Security Admission
  • Continuous Integration/Continuous Deployment (CI/CD) Security: Integrate security testing tools into the CI/CD pipeline. This includes static application security testing (SAST), dynamic application security testing (DAST), and infrastructure as code scanning.
  • Secrets Management: Securely manage secrets like API keys and passwords. Utilize Kubernetes secrets or external secrets management tools like HashiCorp Vault.

Compliance and Policy Enforcement

With the increasing adoption of Kubernetes in various sectors, including those with stringent regulatory requirements like finance and healthcare, compliance becomes even more of a necessity. Ensuring that Kubernetes deployments comply with standards like GDPR, HIPAA, or PCI-DSS is essential for legal and operational integrity.

Key components of compliance and policy enforcement include:

  • Understanding Regulatory Requirements: Start by thoroughly understanding the compliance requirements relevant to your industry. This includes data protection laws, industry-specific regulations, and best practices.
  • Implementing Kubernetes-Specific Policies: Use Kubernetes-native tools like Role-Based Access Control (RBAC), Network Policies, and Pod Security Standards to enforce security and compliance policies within the cluster.
  • Automated Compliance Scanning and Reporting: Implement tools that automatically scan Kubernetes configurations and workloads for compliance.
  • Regular Audits and Reporting: Conduct regular audits with Kubernetes audit logging turned on, to ensure ongoing compliance. Maintain logs and reports for auditing purposes, which is crucial for demonstrating compliance to regulatory bodies.

Integrating Compliance in CI/CD Pipelines

Incorporating compliance into Continuous Integration/Continuous Deployment (CI/CD) pipelines is a critical aspect of maintaining robust security practices in software development, especially in Kubernetes environments. This approach ensures that applications not only meet the functional requirements but also adhere to security and regulatory standards throughout the development lifecycle.

Helpful comparisons

Runtime vs real-time KSPM

Oftentimes, the automatic association of anything ‘real-time’ in cloud native security is ‘run-time.’ But an application does not run in isolation, or outside of its associated infrastructure. In contrast, it runs under a set of parameters, for example, whether the Kubernetes API tells it to run or not, based on a scheduler. In terms of a running workload, an important piece of context is the Kubernetes configuration attached to it. That is what real-time KSPM refers to. For example, is this workload allowed to run in privileged mode, or with cluster admin RBAC privileges? These controls live at the Kubernetes API layer. 

In contrast, runtime itself, in Kubernetes, is a process run by the Kubelet, and encompasses the activity from the Linux (or Windows) kernel of the server (with the Container Runtime Interface, or CRI, and another runtime engine, like Containerd and CRI-O, in between). From a security perspective, runtime, in a silo, is better than KSPM, about telling you what is happening within your application, like if you have malware in the code, for example. That being said, the two must work in tandem. If you’re looking at runtime alerts for workloads that are locked down from a Kubernetes perspective, that is important information that will help you prioritize an investigation.

Cloud security vs K8s Security

Many times, Kubernetes Security is confused with cloud security, and there is an assumption that ‘what works for the cloud will work for Kubernetes - in the end of the day, it’s all configurations, right?’ Wrong. A Kubernetes workload changes every 5 minutes, on average. A cloud account’s configurations change weekly, at best - but sometimes they don’t change for months at a time. You can’t apply a cloud security methodology to securing Kubernetes, because by the time you go to fix a misconfiguration, the workload it is attached to will have already disappeared. And then you have no information about transpired in that workload between polling intervals.

 

Container lifespan

Container vs K8s Security

Kubernetes is an orchestration tool for containers, but it is not the case that if you have container security, you are set for Kubernetes at the same time. For example, take authentication and authorization. If you have cluster admin, or other privileged access to your Kubernetes clusters, your container security won’t help or prevent an attacker from getting a container to do what they want. And then there is the simple fact that, if Kubernetes is misconfigured, container security won’t stop an attacker from getting access to the Kubernetes API, escaping containers, and doing what they want. You definitely need to have elements of container security to protect your clusters, like image scanning and runtime controls, but container and Kubernetes security are not interchangeable.

- K8s Security != Container Security

Kubernetes Security vs GitOps & IAC

GitOps and Infrastructure as Code (IaC) scanning are key players in putting up effective security guardrails for Kubernetes. But they will not tell you whether or not your cluster’s actual activity matches what is in the code that has been defined. It is possible that somebody has come in later in the cycle to move something around manually, and it is also possible that things were not coded as intended, on accident. There is, of course, also the issue of malicious activity, or malicious insiders, who are using their privileges for the wrong purposes (or accidentally).

- Where GitOps and IaC Fall Short in Kubernetes Security

Cloud IAM vs Kubernetes RBAC

Cloud IAM and Kubernetes RBAC work together to perform authentication and authorization into Kubernetes clusters, but each will not get you the other. The ConfigMap does the hard work of translating an IAM role (authentication) to an RBAC role or service account (authorization). There have been attacks that are targeting kubeconfig files, to get these kinds of keys to the kingdom. The most important thing is to be able to view both of them in a connected, real-time attack path.
