The party begins as the other one said… I'm going to show you some things that I think you'll like to be able to exploit your logs and evolve our SIEM into a SOC, Very interesting topics. First we have ElastAlert2, which is an open-source tool that will allow us to generate rule-based alerts with data stored in Elasticsearch.
If you have implemented Crowdsec and Centreon in your organization, I imagine that apart from being happy and resting, You will have everything quite under control; but, and… What if I tell you that from Centreon we can monitor the bans that Crowdsec gives us?? Effectively, when Crowdsec adds an IP address to the blacklist we can alert ourselves via Centreon!
In this post we are going to combine several elements to have voice notifications in our monitoring system. We will of course use local and secure Artificial Intelligence (Ollama) to generate a friendly and human text with the Centreon alert, to later play it on our 7-inch Screen″ thanks to Piper and a voice in perfect Spanish.
For monitoring lovers, For lovers of operational visibility, For lovers of having everything under control… Comes… Monitoring with Centreon – Part II in a podcast for YOU, where we will talk about visualizations and business!
If you have the pleasure and pleasure of having a Volumio to manage the audio of your home (or company), You know how to listen to your MP3s, online radios or Spotify (inter alia) and you also have various speakers with Snapcast distributed, We can manage it like not, from our beloved Home Assistant, Take a look at it, it's amazing!
Another possibility that we can give Home Assistant is to install smoke detectors, These are wireless, powered by a small battery and communicate any notification by radio frequency., There are many types and quite cheap, For just €5 you can make sure that nothing burns in your home or office! This is how cheap we protect ourselves, and in the end we will see how to alert with Telegram in case there is smoke.
In this document we will see something very interesting, let's see how to implement a Centreon notification system with Telegram, so we will receive the alerts of our monitoring with Telegram messages directly to our mobile phones. I hope you are interested!
If we want to analyze some type of gas with a Raspberry Pi, we can make it very simple with MQ sensors, we will only need to know in any case which sensor to obtain depending on the gases to be analyzed and that's it, We will see in this post how to connect it and get the values. As usual, at the end we will save the data obtained in a MySQL database to visualize it from Grafana!
