IR Playbook: First 60 Minutes of a Breach

Introduction

This guide covers IR Playbook: First 60 Minutes of a Breach for teams handling digital records, investigations, or compliance in India. Whether your goal is how-to clarity or a practical workflow you can defend under audit, hashing and tamper-evident certificates turn abstract policy into verifiable proof. For deeper context, see the guide on incident response evidence certificate, the guide on hash calculator.html#hash tool, the guide on hash calculator download.

Why this matters now

Organisations increasingly need to show that files, backups, exports, and logs were not altered after collection. Keywords such as incident response playbook, first hour breach response, breach containment steps reflect real search intent from investigators, lawyers, IT staff, and auditors. Recording a cryptographic hash at the point of collection - and optionally sealing it in a Section 63 BSA / 65B IEA certificate - gives you a repeatable integrity checkpoint.

Practical workflow with e-Dex

Use the free in-browser hash tool for quick checks, or download e-Dex for fully offline hashing, folder manifests, chain-of-custody logs, and court-ready PDF certificates. Work read-only on evidence where possible; hash before and after any copy; store hashes separately from the evidence itself.

Common pitfalls to avoid

Avoid relying on broken algorithms alone for proof, skipping write-protection on original media, hashing only filenames instead of file contents, or comparing hashes in the wrong case format. Document who collected what, when, and with which tool; gaps here are harder to fix than a mismatched hash.

Frequently Asked Questions

What to preserve before containing a breach?
Start with a modern hash (SHA-256 or BLAKE3), preserve the original read-only where you can, and attach a certificate that records the digest, timestamp, and custodian statement. Lock down evidence integrity in minute one with e-Dex.
