  • SAST, DAST, IAST and RASP

    In this article, we’re going to look at the differences between the various cybersecurity defence techniques.

    My personal opinion on these different approaches is that if you start with DevSecOps or security in IT in general, the SAST approach makes the most sense. This is where the greatest potential threat can be eliminated with minimal effort.

    Here you can identify four main groups, which we will go through briefly one after another to illustrate the advantages and disadvantages.

  • Troubleshooting Java Processes Running on Your Machine

    When your application has some problem, the first thing to check is running processes on the machine.

    For Linux OS we generally use ps -ef. ps is one of the most used Linux troubleshooting commands. The JDK provides similar functionality for Java processes through jps. The jps command-line utility provides a list of all running Java processes on a machine for which the user has access rights. The access rights are determined by access-control mechanisms specific to the operating system.

    Simplify Protocol Refactoring

    The other day, I went grocery shopping. While waiting in line, I thought about some struggles I had in a test I wrote earlier that day.

    When it was my turn, the cashier scanned my items and said what I owe him. And I just gave him my whole wallet. He stared at me blankly and gave it back. A little confused for a second, I took out my card, paid, and left the store. And at that point, it hit me what was wrong with my test.

    Instead of giving the cashier our whole wallet, let’s just give them what they need. Not more, not less.

    Sometimes, you need to make code more trivial to see the higher-level patterns that solve the issue at hand more elegantly.
