Four Tips for Creating a Secure Kubernetes Security Strategy

 Containerization and Kubernetes pose new security threats. Red Hat's 2021 State of Kubernetes security report found that security is the greatest concern for container strategies, with 94% of respondents reporting at least one security incident in their Kubernetes environment within the last 12 months.

It is important to make sure that containerized development doesn't limit your agility or cause security problems in Kubernetes production environments. How would such a policy look like? These are the top four ways to make sure Kubernetes security remains tight.

What security concerns are most urgent to Kubernetes?

Recalling the Red Hat report in the intro, real-world data gives valuable insight into the most common Kubernetes security problems. DevOps engineers and engineers consider the following four security issues to be a concern in Kubernetes environments.

1. Detected misconfiguration

Because container orchestration is declarative, there are many misconfiguration risks that actors could exploit. These risks could expose sensitive data or increase the attack surface of your cloud-native app. This is because humans pose the greatest cybersecurity threat to businesses.

Security is not provided by default Kubernetes settings. It is easy for default Kubernetes settings to slip into production environments. This allows for agility and other pursuits. Vulnerable deployments are as easy as allowing scripts/shell command to be placed in containers or running them unnecessarily as root.

1. Security incident during runtime

This is the second-most important concern. Most configuration mistakes made during the build phase will not be obvious until runtime once containers are deployed. Runtime security problems can include hidden malware, privilege escalation attacks, and weak access controls that permit unauthorized containers running. Security must be maintained at all stages of development, orchestration and runtime. However, it is crucial to safeguard against security threats in Kubernetes environments.

1. Major vulnerability to address

This is an obvious concern. Major flaws can cause disastrous business outcomes. It is important to address major vulnerabilities quickly. This could cause delays in application rollouts and feature upgrades.

1. Failed audit

Businesses must adhere to a wide range of data privacy regulations. Breach of these regulations can lead to heavy fines or reputational damage. An audit of Kubernetes containers can uncover compliance problems. This is a troubling finding as it can reveal compliance issues in your development environments.

Kubernetes security: Why should you be concerned

Kubernetes security is a priority as it directly impacts your development work. Container orchestration is agile, but security problems can quickly slow down build- and deployment workflows.

Another reason to be concerned is the possibility of serious data breaches due to security holes in production environments. In a world where data breaches average $4.24million, this is unacceptable. This does not include reputational damage that media spotlights can cause by highlighting insecure development practices that led to the breach.

4 Tips To Strengthen Kubernetes Safety

Kubernetes security can be complex. These four tips can help you create a safer container ecosystem.

Tip 1: Incorporate security in the development phase

A paradox can be created by developers who disregard security in favor of agility. Security is often seen as a barrier to development agility. Security issues that are discovered during Kubernetes app installation can slow down development and cause delays in rollout.

The answer is to adopt a DevSecOps strategy which includes security at every stage of the application development process. DevSecOps is about automating as quickly as possible in order to identify security issues early. Security tools for code are invaluable for detecting security problems in code, Kubernetes configurations, and other artifacts throughout the development cycle.

Tip 2: Be aware of misconfigurations

Modifying Kubernetes architecture components is possible, regardless of whether you are tweaking control plane or worker nodes, or creating a container-image using your own code. There are risks associated with excessive permissions or insecure ports.

It is impossible to rely on human intervention to correct misconfigurations in complex Kubernetes ecosystem. Multiple configurations can be applied to a single workload. Multiplying that number by multiple workloads will quickly exhaust your resources for manually searching for security issues. This is true regardless of how many people are involved in application security.

AI can do the job faster than you. An AI-powered scanner engine should be used to detect security problems.

Tip 3: Use Kubernetes secrets

Kubernetes secrets enable you to access the resources that your applications need to function correctly. These resources could include sensitive applications, databases or infrastructure. The secrets are stored separately from the application's code and as objects. The application doesn't need to keep the contents.

This makes it possible to make resources available to other people without having to store them in containers images or pod definitions. The Kubernetes secrets can be extremely useful. It is vital to check for authorization, authentication credentials, and keys that might accidentally get into source code repositories. This document provides additional information on Kubernetes secrets, and how to set them.

Tip #4 - Invest in security strategies

As more companies try to reduce IT costs by 20%, Kubernetes adoption will increase. While developers are aware of the other benefits of Kubernetes and the impact it has on bottom-line, decision-makers often focus their attention on Kubernetes' impact on the bottom line. Be aware that blindly adopting Kubernetes can lead to costly investments in security tools and strategies to improve Kubernetes security.

These are just a few of the strategies and tools that can be used for Kubernetes security.

• Security engines that detect security issues quickly during the development process.
• Verify container images to flag potential vulnerabilities and remove malicious pictures
• A comprehensive data management platform that provides data protection, disaster recovery, and data security capabilities.
• Focus on a efficient network separation and hardening process to prevent escalation.
• To manage access control based on role, use the principle of least privilege

Creating Secure Digital Transformation Strategy

Kubernetes containers can be orchestrated for internal or customer-facing purposes. This type of development has the overarching strategic advantage of driving modern digital transformation strategies. If you don't incorporate security into your workflows, it can be a hindrance to your efforts.
