Trainer Name: Himanshu Kumar Das & Prajal Kulkarni
Title: Building An Attack Monitoring Solution & Hardening Infrastructure Services
Duration: 2 Days
Dates: 27th - 28th Feb 2019

Overview

The 2-days training course outlines defense in depth on Network, Application & System Layer of the OSI model. During the 2-day training programme, we would conduct hands-on exercises on simulating, correlating, analyzing and mitigating multiple attacks ranging from Layer 4 to Layer 7, and also on how to defend against these attacks by hardening your internet facing services.

Each topic in our session would outline day-day security requirements not only for a small startup but also for well-established enterprise.

Detailed Course Abstract

With the growing trend of Big data, companies tend to rely on high-cost SIEM solutions. Continuous security monitoring/alerting for medium and big organization is a huge challenge in hand today. Logs from thousands of endpoints, servers, and perimeter devices are difficult to aggregate, analyze and correlate in real time that can enable better security incident response & event handling. Organizations usually end up with massive data breaches due to lack of visibility in their network activities across the infrastructure. Our course would expose you to take control of enterprise-wide logs, analyze them in real time using the ELK frameworks. During our course, you would learn to scale the Elastic Stack and generate powerful visualization & data modeling using kibana making analysis of data and decision making simple.

This training will also cover simulating real-world attack scenarios, alerts customization necessary to respond to real-world attack anomalies. With growing cloud-based offerings it becomes crucial to understand systems for detecting and responding to attacks. With tools like osquery you would learn how a scalable solution for system-level anomaly detection can be built. We would also cover tools and techniques for strengthening and hardening production systems by using inbuilt tools and well-known techniques adhering to industry standards.

This training is meant for security enthusiast, DevOps, and startups trying to build an in-house solution. This will be a great learning to set-up one's own an affordable Security Analytics Platform.

What To Expect

Over the duration of the 2-days workshop, you would get a detailed knowledge on how to build a no-cost attack monitoring and system hardening solution for external as well as internal security both on the cloud as well as an enterprise network. We will have various classroom exercise to engage participants on real-world security use-cases as well as scaling the entire Elastic Stack for large-scale networks. Labs will include all necessary tools and configs necessary to run a fully functional stack for attack monitoring.
The workshop would have a mega challenge at the end of the course on a pre-populated data to get a hands-on experience on production grade Elastic Stack.

What Not To Expect:

  • Elasticsearch programming
  • Writing Plugins for Logstash
  • Any exercise/demo on a physical network device.

Pre-requisite of Training

  • A laptop with administrator privileges.
  • 30 GB of free Hard Disk Space.
  • 8 GB of RAM on host laptop.
  • Laptop should have a working wireless and wired/Ethernet connection.
  • Latest Oracle Virtualbox(preferred) or VMWare Workstation or VMWare Fusion installed
  • Other virtualization software might work but we will not be able to provide support for that.

Note: We do not support Windows XP

What you will get

  • Tools and software provided for the training.
  • Completely documented script and programs
  • A simple to follow step by step walkthrough of the entire training in a PDF file
  • Virtual machines with the code used during the training so that you can even practice after the training is over.
