02 · BEFORE YOU START
The four rules common to every incident
Whatever the scenario, you must act fast without erasing the material that will later make it possible to understand the facts and justify your steps.
1. Stop the exposure
Cut off the remote session, block any exposed means of payment, close unknown sessions and change your passwords from a trusted device.
2. Keep the evidence
Keep calls, text messages, emails, screenshots, numbers, receipts, bank references, login alerts and the timeline of events.
3. Prioritise your accounts
Your main email, bank, phone, cloud, social media and password manager come before secondary accounts.
4. Document your steps
Stopping a card, disputing a payment, filing a complaint, reporting, exchanges with the bank or the platforms: every action must leave a trace.
A guide helps you avoid panic and mistakes. It does not replace advice on your own case, and we never guarantee a result: neither identifying a perpetrator, nor recovering funds.
03 · THE DOCTRINE
Before the articles, the doctrine. Cybersecurity is a governance discipline.
The CODEX brings together the principles that guide every engagement: cybersecurity seen as a governance discipline that serves decisions, facts and people.
The Executive edition gives the essentials in about twenty minutes, useful well beyond businesses alone. The Founding edition develops the ten Books and is distributed on a controlled basis.
