Universal Log Pre-processing Framework

National Technical Research Organisation (NTRO) · Miscellaneous · Software

The problem is real but the category is solved by mature tools — make the no-code extensibility mechanism your genuine contribution, because a straight log-normaliser is a reimplementation of Logstash a judge already knows.

What it actually is

Enterprises collect logs from everything — servers, firewalls, cloud services, containers, IoT — in a dozen different formats, and security teams waste huge effort writing custom parsers before the data is usable. The ask is a framework that ingests logs in any format, parses and normalises them into one unified schema while keeping the raw original, and scales to billions of events a day.

What to build

A log pre-processing framework that ingests events from diverse sources and formats — Syslog, JSON, XML, CSV, CEF, LEEF, proprietary schemas — parses and normalises them into a unified event schema aligned to a standard like the Elastic Common Schema or OCSF while preserving the complete raw event for forensic and compliance use, with an extensible parser mechanism so new sources can be added without code changes, field extraction and enrichment, and an architecture designed to scale to high-volume Big Data ingestion feeding SIEM, data-lake or ML platforms downstream.

Smallest thing that wins the room

Ingest three genuinely different log formats — a firewall CEF line, a JSON cloud audit event and a raw syslog line — and show all three normalised into the same unified schema with common fields aligned, the raw original preserved alongside each, and a new source format added through configuration rather than code.

How crowded this one gets

A guess, projected from the 2025 statements — the last year where both the submission counts and the winners were published.

A normal-sized field. Your idea has to be good, not miraculous.

Why: defence, intelligence and space bodies drew small fields.

This is a guess, not a fact

Nobody has published 2026’s numbers yet. This is an analysed estimate from last year’s pattern, so please do not take it as the truth — check the live counter on the SIH portal before you decide anything. The range covers the middle half of likely outcomes, so one statement in two lands outside it. Entry closes at 500 ideas per statement, so no range goes past that — a statement that reaches the cap fills and shuts rather than drawing an unlimited crowd. The model reads only three things a team can see before choosing — software or hardware, the theme, and what kind of body posted it — and those explain about a quarter of the variation in last year’s field sizes (R² 0.25 on held-out statements). Trust the band more than the number, and the ordering more than either. It cannot see how good your idea is, which is the part that actually decides it.

The scores

The number is the shorthand. The line under it is the reason.

What you will be writing

  • Extensible parser plugin mechanism
  • ML-assisted log format inference (optional)
  • Kafka high-throughput ingestion
  • Raw-event preservation store
  • Log management
  • Security data engineering
  • SIEM pre-processing
