Docker Secrets are config files that contain sensitive information, like passwords, tokens, and keys. Unlike most applications where users authenticate (enter a username and password) to access your database or other components, Docker uses environment variables to expose the secrets' values. You can set those container environment variables however you wish--but remember: they are accessible in plain text, so you should always strive to keep your secrets secret. You can manage Docker Secrets and access them from within the container, yet expose their values to other applications as environment variables outside of the container as well. This means that you could have different 'versions' of an application, each using a different version of your database schema, for example, each one using a different database username and password.

So how can you keep your secrets safe? Here are a few tips:

1. Use the latest Docker version and TLS (SSL) encryption to connect to the repository. This will help avoid tampering with your secrets as they are transported across networks. Doing so can be complicated with older versions of Docker, so it's worth investing the time in upgrading to the latest version. The thing is, newer versions of Docker also have additional security features, like exposing secrets and providing a secure way to store and share them.

2. Use a secret management solution like HashiCorp Vault or Google Cloud's Key Management Service, which work closely with Docker Secrets. These services will help you store your secrets securely and make sure they are only accessible to the approved users with access. For example, if you have a dev/test environment and need secrets to be accessed by that network, only the users with access should be able to see them. This means that your secrets management solution needs to have fine-grained access controls for it to work well with Docker. Thankfully, both Vault and KMS are configured this way.

3. Use the Docker Secrets Volume Driver, which allows you to mount a volume from your containers to another location, like a file system or block device outside of the container, but still have access to those values inside the container. In this way, you can expose secrets as plain text on an environment variable outside the container and make sure they are not visible inside the container. Being able to mount volumes and specific directories or files on a container has many other benefits as well. For example, you can use Docker Secrets Volume Driver to store your secrets in one place, like a mounted volume, instead of writing them directly into your Dockerfile. This helps reduce clutter and ensures that changes to a secret can be tracked more easily.

4. Take advantage of role-based access control (RBAC) within your containers, and limit the users who should have access to these secrets or the applications that use them. For example, if you are using an orchestrator like Kubernetes, you could limit specific user roles only to be able to access secrets that are relevant to their role.

5. Always encrypt sensitive data (passwords, API keys) before adding them as Docker Secrets. This ensures that potential hackers can't access your passwords even if they get ahold of your secret file or repository.

6. Regularly rotate your secrets to avoid having somebody accidentally leave a copy of a secret lying around, or worse: be targeted by hackers who have access to it. Vault and KMS both have options for rotating secrets automatically, so you don't have to worry about forgetting!

7. Use strong passwords and keys to access your secrets, and don't expose them to the public. This will make it more difficult for hackers to get at your secrets, especially if they use long, complicated passwords or keys (such as with an SSH key).

Keeping your Docker Secrets secure is easy when you follow these tips and remember some basic security principles: encrypt, rotate, and store your secrets securely. Nothing is worse than having your database credentials stolen and rebuilding the whole application. So do yourself a favor, and keep your secrets safe.

When you talk about container security, a critical component inevitably comes up: container runtime. But what exactly is container runtime, and why should you care about it? We'll break down the answers to those questions in this article. At its core, container runtime is the software element responsible for running your containers on your host system. And while this may seem simple enough, it's actually a critical component in your container environment.

There are three main container runtimes:

• Low-level container runtime: These containers run the OS kernel and core functionalities, like networking. Some of the most popular low-level container runtimes are runC, rkt, and containerd.
• High-level container runtime: These containers run the applications and don't include an OS kernel or other components. The most common high-level container runtime is Docker, which runs on top of a low-level container runtime (usually runC), and Windows Containers.
• Sandboxed and Virtualized Container Runtimes: These runtimes are designed to isolate applications from the host OS, like CT-Scan. Sandboxed runtimes give users more control over their applications, so they can easily manage and maintain them. In contrast, virtualized runtimes improve host isolation by running the containerized process in a separate virtual machine rather than on the main kernel.

As you can see, the container runtime's role is critical in your containers' security and performance. But why should you care about container runtime? Well, there are a few reasons why it's essential.

1. If a container runtime isn't properly configured, it could open up security vulnerabilities in your system. And as we all know, a vulnerable system is what cybercriminals are looking for – so you need to ensure that the runtime you're using has proper security practices and protocols. If your container runtime is compromised, you'll want to ensure that the rest of your system isn't affected. That's something you can achieve with a properly configured runtime.

2. Container runtimes also handle logging and monitoring for your containers, so it's important to make sure that you have the right runtime in place for optimal monitoring and logging practices. This only means you can detect issues or threats more quickly and easily. For example, in the case of Docker: it has its own container runtime called runC, which is a standalone component that runs in your system. RunC then orchestrates the runtime for your containers and provides the environment for container execution.

3. Finally, a good container runtime can help improve the overall performance of your system by reducing latencies. So, finding a reliable container runtime is essential if you want to eliminate unnecessary bottlenecks and speed up your processes. Container runtime is an important component to consider – not only when it comes to security and monitoring but also for overall performance and management. And by choosing the right container runtime, you'll be able to optimize your container environment and reduce security risks.

The age of containerization has ushered in a new era of container security: one where there are many open-source tools and services to help you monitor, secure, and optimize your containers.

Scanning for vulnerabilities in your containers doesn't have to be difficult or tedious; there are now many automated tools and services that make it easy to scan your container images continuously. Whether you're working with a pre-built container or building your own, there are several options for scanning your containers for vulnerabilities. You must prioritize constant scanning of your applications and services if you're looking to improve your container security posture. By staying on top of any changes to your infrastructure, you can better protect yourself from new threats and attacks.

4. Ensures containers are kept up-to-date with the latest security patching

Keeping your containers up-to-date with the latest security patches is another crucial way to avoid potential threats. By scanning your containers for vulnerabilities and updating them with any necessary patches, you can mitigate the risk of a successful attack on your organization's infrastructure. When it comes to security, it's essential to stay on top of any changes that might affect your infrastructure. Whether deploying a new application or updating an existing one, continuous scanning can help ensure that your containers are kept up-to-date with the latest security patches and measures.

5. Minimizes downtime and disruption to the organization

Lastly, the need for constant scanning is driven by the fact that it can minimize the impact of an attack on your organization. By monitoring for vulnerabilities and mitigating them before they turn into significant issues, you can greatly reduce any downtime or disruption to your services. Regular scanning is a critical part of maintaining a strong container security posture. Whether you're deploying new applications or updating existing ones, continuous scanning can help minimize the impact of potential threats and attacks on your organization. It takes a lot of effort to stay on top of any changes to your infrastructure, but the benefits of regular scanning make it a worthwhile investment.
