Red Team Operations Fundamentals
Red team vs pentest, engagement types, objectives, rules of engagement, and what a good red team report looks like.
DevSecOps Fundamentals
Shift-left + extend-right, SDLC security map, where each control lives, metrics that matter, and the 30-day rollout.
Mobile App Security Threat Model
How mobile apps differ from web, Android/iOS security models, OWASP Mobile Top 10, lab setup, and scoping questions.
SOC Fundamentals
SOC tiered analyst model, triage workflow, shift patterns, runbooks, and India-specific operational constraints.
Windows Security Fundamentals
Windows hardening looks different from Linux. Different tools, different attacker tradecraft, different audit surface. This module covers the baseline every production Windows server and Windows 10/11 workstation should have — without drowning you in 500 pages of MS docs. The hardening stack Authentication — MFA, account policies, Credential Guard Network — firewall, SMB, RDP Endpoint […]
Linux Hardening Fundamentals
You get root on a fresh Linux server. Now what? Default installs — whether Ubuntu, RHEL, Amazon Linux — are not hardened out of the box. This module is your opinionated checklist: the baseline controls every production Linux server should have before it sees traffic. The hardening stack Network — firewall, SSH, services Users & […]
Nmap — Network Discovery and Port Scanning
Nmap is the first tool every security practitioner reaches for. Pen-tester? You’re using nmap. Defender auditing your attack surface? Nmap. Discovered a new subnet you need to profile? Nmap. This module takes you from “I’ve typed nmap once” to “I can scan intelligently, interpret results, and avoid triggering every IDS in the building.” What nmap […]
Cloud Security Mental Models
Cloud security is often taught as a taxonomy — “AWS IAM works like this, GCP IAM works like this, Azure is different.” That’s how you end up memorising 300 service-specific checkboxes without ever understanding what matters. This module inverts the usual approach: we give you the mental models that apply across AWS, Azure, GCP, and […]
AD Architecture Fundamentals
Active Directory is the authentication backbone of ~95% of enterprise environments in India and globally. Every enterprise breach of note — from Colonial Pipeline to Maersk to countless Indian banks — involved AD compromise somewhere on the kill chain. Understand AD and you understand enterprise attack paths; stay ignorant and you audit blind. This module […]
Packet Analysis with Wireshark — From “Open the PCAP” to Diagnosing Real Incidents
Wireshark is the universal protocol analyser. Every IR investigation, network design review, and "this protocol is misbehaving" debug eventually becomes a Wireshark session. This module teaches the workflow that distinguishes a beginner from a practitioner: capture filters vs dis
