Modern software architecture is always changing. Today, containers such as Docker are becoming the most commonly-used development architecture. Most top companies are using containers, due to their convenience and their ability to support microservices, and other modern features.
But with any modern software architecture, there are vulnerabilities that must be addressed in order to keep your data and company safe from malicious hacks and data breaches. So, in this article, we’ll be taking a look at some of the best ways that you can contain app vulnerabilities by using the latest technologies.
1. Start with Your Container Management Software
Kubernetes is, by far, the most popular container management and orchestration software, although Docker Swarm is used by some smaller organizations. This means it’s critical to secure your Kubernetes deployment, to keep your containers safe.
Continuous Security Vulnerability Scanning is a great way to do this. Using this technique, you can look for known vulnerabilities – also called CVEs – and continuously assess Docker containers and images in order to make sure that any potential threats are contained, and the images are updated to patch out the vulnerability.
In addition, the Kubernetes rolling updates feature should be used to redeploy containers once the source image has been changed, to keep your data safe and ensure that the image-container relationship is not broken.
2. Only Allow Authorized Images in Your Environment
Your organization should have a policy in place to determine which software images are allowed to run, to avoid the risk of vulnerable or dangerous containers being implemented. Never allow anyone to run and download images from unknown sources.
You should have a list of which images are allowed, and a process by which developers must get authorization to deploy new images, or use a non-approved image. Keep lists of approved images in a private file, to ensure that they are secure, and that no malicious attackers can gain access to this information.
3. Consider a Third Party Security Provider
There are many companies which offer CI/CD (Continuous Integration, Continuous Delivery) security software that can be used with Kubernetes and containers. Most managed service providers (MSPs) use their own tools to provide you with enhanced security.
The IBM Cloud, for example, builds security scanning software into the platform by default, reducing the risk of breaches or data loss. Other providers of this technology include Twistlock, Aqua Security, and StackRox. Consider if partnering with a security company could be the right move for you.
4. Bridge the Gap Between Old And New
Despite how new technologies like containers are in the world of modern software architecture, you can’t neglect the basics, like API management and identity verification.
All third-party APIs used in your development environment should be vetted and regularly updated to ensure they are free of vulnerabilities, and strong identity verification tools need to be used to block unauthorized users from accessing development environments.
Containers Are New – But That Doesn’t Mean You Can Abandon Security Best Practices
Regular patching and maintenance, proper API and identity verification, steps to prevent unauthorized images from being created – the steps you need to take to protect your container-based environment are not new.
But there’s a reason for this – good security standards never go out of fashion. So make sure you follow these tips, and protect your development environments from data loss, breaches, and hacks.
