Awareness Programmes That Change Behaviour
Why this module exists. Awareness training is the single most-funded, least-effective security investment in most Indian enterprises. The right structure — frequent, targeted, feedback-driven — produces measurable behaviour change. The wrong structure — annual hour-long video — produces compliance-checkbox theatre. This module is how to build the right one. What does not work Annual one-hour […]
Post-Quantum Cryptography 101 — NIST FIPS 203, 204, 205 (ML-KEM, ML-DSA, SLH-DSA) Explained
NIST's final PQ standards orientation: ML-KEM (FIPS 203) replaces RSA/ECDH, ML-DSA (FIPS 204) replaces RSA/ECDSA signatures, SLH-DSA (FIPS 205) is the conservative hash-based alternative. Migration map and size impact.
Grover’s Algorithm — Symmetric Crypto’s New Math (Hint: AES-256 Wins)
Grover halves symmetric crypto security in bits — AES-128 weakened, AES-256 still safe. SHA-256 collision resistance halves but stays secure. Practical migration: use AES-256, SHA-384 for long-lived data. Module 4.
Shor’s Algorithm Explained — Why RSA and ECC Will Break
Shor's algorithm factorises integers and computes discrete logs in polynomial time on a quantum computer — breaking RSA and ECC. How it works at intuition level, hardware requirements, and the Mosca theorem applied. Module 3.
Why Quantum Matters for Cybersecurity — The Post-Quantum Threat in Plain English
The post-quantum threat quantified — what crypto breaks, when CRQC arrives, store-now-decrypt-later risk, Mosca theorem, and what your CISO should be telling the board today. Module 2 of the Quantum Computing track.
What is Quantum Computing — Qubits, Superposition, Entanglement (Beginner)
Quantum computing fundamentals for security practitioners — qubits, superposition, entanglement, gates, and what quantum computers can and cannot do. Module 1 of the RingSafe Quantum Computing track.
Caido for Web Pentest — A Modern Alternative to Burp Suite Pro (Hands-On Walkthrough)
Caido is the first credible challenger to Burp Suite Pro — Rust-built, web UI, multi-tester collaboration. Architecture comparison, workflow-by-workflow analysis of where Caido beats Burp and where Burp still wins, and a 4-week migration plan for Indian pentest teams.
Build Your Own Local LLM — Ollama, vLLM, llama.cpp from Scratch
Self-hosting an LLM costs less than ChatGPT Plus, runs on a gaming laptop, and gives you full data sovereignty (DPDP-compliant out of the box). This module walks through hardware requirements, three runtime choices, model selection, and the production setup checklist. By the end
Prompt Injection — Direct, Indirect, and Why It Will Not Be Patched
Prompt injection is to LLMs what SQL injection was to web apps in 2002 — except this time there is no equivalent of parameterised queries. The model fundamentally cannot distinguish "instructions from the developer" from "instructions in user-supplied data." This module covers th
AI Security 101 — Why ML Systems Break Differently
Traditional software is deterministic. ML systems are probabilistic, learn from data, and respond to natural language. That changes the entire threat model — input is no longer just bytes, training data becomes a supply-chain risk, and "vulnerabilities" can be invisible to code r
