Title: Building An Enterprise Grade Security Analytics Platform Using Elastic Stack
Duration: 2 Days
Dates: 4th - 5th March 2020

Short Abstract

Some of the prevalent top challenges into infosec ecosystem most companies are spending their effort, surfaces from dealing with data leaks, multiple forms of phishing attacks, ransomware attacks and DDoS. In many cases, companies take a reactive approach after an incident breakout. This retrospective provides lots of avenues for the security team to take a blue team approach and move the bar to the proactive side. We are teaching a technical training which will help you to understand on how to start setting up an ELK pipeline and gradually add data points from multiple sources like firewall, application servers, system, etc. to gain more visibility across your organization.

Full Course Abstract

During 2 days of our class:

  • We will have very collaborative exercises on each topic from our syllabus between all the participants. Also, enabling participants to apply some of their ideas in the class.
  • You will get an in-depth understanding of how to identify the right set of data sources for security analytics, how to correlate and how to enrich those data sources to identify anomalies, all of these from within your organization. We will also cover some real-world case studies(threat intel, pentesting) as well.
  • We will take a platform focused approach(cloud/data centers) and teach the class about some of the most popular open source frameworks like MITRE ATT&CK Framework, osquery by integrating these into ELK Stack

At the end of our training, participants will walk away with a VM lab containing all of the custom scripts, custom configurations, slides with all the commands and notes from our training.

Additional Course Details

Each topic in our course has a story line. We usually start our topics with a basic theoretical explanation and then move on to connecting the topic with a real world use case;includes but not limited to:

  • challenges one could face in a setup/configuration
  • how to leverage the topic under discussion in an enterprise setup
  • strong explanation on what problem could be solved by topic in discussion
  • exercise to get an hands-on experience
    E.g. topic: elasticsearch
  • We take the first topic of our class on elasticsearch, briefly talk about how elasticsearch project evolved and what problem does it solves. We explain production setup for elasticsearch and challenges one could face during setup/scaling. Next, we move to hands-on and using head plugin we engage with participants to help them understand how indexing happens in elasticsearch via leveraging elasticsearch REST API.

Some of the topics(e.g. shipping logs to central machine) requires us to divide our participants into groups(viz. shipper and indexer) so that participants can understand the concepts easily and enable them to debug challenges they could face during actual production setup.

For topics like alerting where we have 4-5 types of alerting. We explain the configuration/settings and rule for 1 alert type to our participants. Once they are confident, we do a classwork with other rule types and ask participants to do it themselves.

Each topic in our class has a strong emphasis points. E.g. Setup of elasticsearch is very important, similarly, setup of logstash may not be very important but configuration of logstash is crucial. Whereas, alerting the right way is important. During our discussion/exercise, we ensure these key points are being conveyed to participants.

Our VM is preconfigured with setup on elastic stack and we place most of the config file inside VM to ensure we don't spend time in setting up or installing any part of software/code.

We have a local etherpad setup during our training which allows participants to paste their errors, ask questions, share commands so that everyone in class could leverage the information.
