So, you want to build a Java application and run it inside a Docker image? Wouldn’t it be awesome if you knew what best practices to follow when building a Java container with Docker? Let me help you out with this one! In the following cheatsheet, I will provide you with best practices to build a production-grade Java container. In the Java container example, I build using these guidelines, I will focus on creating an optimized secure Java container for your application.

Every Java developer should follow coding standards and best practices to develop secure Java code. It is critical your code is not vulnerable to exploits or malicious attacks. In recent times, even big organizations like eBay, the CIA, and the IRS have fallen victim to vulnerabilities in their applications that have been discovered and exploited by attackers. The following guidelines provide a solid foundation for writing secure Java code and applications.

Imagine you are a Java programmer and that you just decided you want to use Snyk Open Source scanning to help you find security problems in your third party libraries. Good call! However, after connecting your repository to the Snyk Open Source scanner, you find out that you have ten or maybe even 50 vulnerabilities in the packages you depend on. The major question is: where do I start?

In 2017, we started a blog series talking about how to securely implement a crypto-system in java. How to Get Started Using Java Cryptography Securely touches upon the basics of Java crypto, followed by posts around various crypto primitives Cryptographically Secure Pseudo-Random Number Generator (CSPRNG), Encryption/Decryption, and Message Digests. We also released a Java Crypto Module for easier dockerization of injectable modules exposing Crypto services via an API.
