Protecting Yourself and the Client's Data (OPSEC)

Why this matters

Even authorised testing should follow good operational security: don't use personal accounts, run tools from segregated infrastructure, encrypt + delete client data after the engagement, share evidence via secure channels. The reasons are both legal (data protection) and practical (avoid being mistaken for a real attacker).

Demo

Engagement hygiene: dedicated VPN endpoint for engagement traffic, separate VM per client, daily encrypted backups to client-approved storage, evidence deleted from local + cloud at engagement end. Use signed comms (Signal, Keybase) for sensitive findings until report is delivered.

Try it yourself

1. Set up a pentest VM template with isolated networking. Snapshot pristine state.
2. Establish a comms channel with a hypothetical client. Decide what data goes where.
3. Read about real-world OPSEC failures in offensive security teams (e.g. compromised C2 infrastructure).
