What is Elastic Stack?
Elastic stack is the collection of different open source components linked together to help users take the data from any source and in any format and perform a search, analyze and visualize the data in real-time.
The Elastic Stack Study Notes & Guide
The Elastic Stack Study Notes & guide explores the Elastic Stack (ELK), an open-source suite that includes Elasticsearch, Logstash, Kibana, and Beats, used primarily for data ingestion, storage, analysis, and visualization. It is highly valuable for data analysts, security engineers, and operations teams to manage real-time logs and metrics.
The ELK Stack is a robust platform for managing and analyzing large-scale, real-time data. It starts with Elasticsearch for storage and search capabilities, Logstash or Beats for data ingestion, and Kibana for visualization. Security engineers focus on integrating log data from devices and using KQL for investigation.
Data analysts load and analyze datasets with customized index templates. The guide offers detailed installation instructions for multiple OS and methods (Docker, Linux, Windows), describes architecture including nodes and clusters, and contrasts data ingestion methods (Beats vs. Logstash). Advanced Kibana features include dashboards, Canvas, maps, and alerting. Finally, it provides cyber investigation use-cases like brute-force detection and phishing analysis using KQL queries and visual tools.

Purpose of Using Elastic Stack
Elastic Stack or Elastic, Logstash & Kibana are mainly used for:
- Data analytics.
- Security and threat detection.
- Performance monitoring.
What is Elastic Search
Elasticsearch is a full-text search and analytics engine used to store JSON-formated documents. Elasticsearch is an important component used to store, analyze, perform correlation on the data, etc.
It is built on top of Apache Lucene and provides a scalable solution for full-text search, structured querying, and data analysis. Elasticsearch supports RESTFul API to interact with the data.
What about the notes updates?
if you have been following my YouTube Channel, you definitely know that those who subscribe to the second tier of my channel membership they instantly get access to a vast catalog of cybersecurity, penetration testing, digital marketing, system administration and data analytics notes catalog for 10$ along with the ability to receive all notes updates as long as they are subscribed so what does that mean?
This means if you want to stay up to date with the changes and updates to the notes and get access to other categories, I encourage to join the channel membership second tier instead. However, if you are fine with downloading the current version of this section of the notes then you can buy this booklet instead for a one-time payment.
Will the prices of this booklet change in the future?
Once another version of this E-book is released, which it will, the price will slightly change as the booklet will include more contents, notes and illustrations.
