Hey, there. This is part five of the Elastic SIEM for home and small business blog series. If you haven’t read the first, second, and third blogs, you may want to before going any further. In the Getting started blog, we created our Elasticsearch Service deployment and started collecting data from one of our computers using Winlogbeat. In the Securing cluster access blog, we secured access to our cluster by restricting privileges for users and Beats.

Today’s cyber threat landscape is diverse – new threats are emerging every day and cyber criminals are being sophisticated in terms of their covert nature and ability to launch attacks in massive frequency with minimal chances of detection.

As someone in the technology field I follow the steady stream of new and exciting products and gadgets that come out at least twice a year. I am constantly upgrading my tech and my IT work tools in keeping with what is new.

I often think about the effect that my constant upgrading has on the environment.

When it comes to protecting sensitive data, preventing data breaches and detecting cyber attacks, you need a way to track whether you're meeting your goals. Key performance indicators (KPIs) are an effective way to measure the success of your cybersecurity program and aid in decision-making.

In the previous post, we covered some of the frameworks accessible by kernel extensions that provide information about file system, process, and network events. These frameworks included the Mandatory Access Control Framework, the KAuth framework, and the IP/socket filter frameworks. In this post, we will go into the various tips and tricks that can be used in order to obtain even more information regarding system events.

How resilient is your application? Maybe you've set up a suite of logging tools, an APM, and tests to handle all your own code. What happens when a third-party API goes down? What happens when it stays up, but slows down to the point that your dependent services start to fail? Finding a modern application that doesn't rely on third-party APIs is rare, particularly with the abundance of social login and sharing.
