1. Establish a Single Point of Contact (SPOC)
Control Requirement: A formal point of contact must be identified for reporting security events.
Required Implementation Step: Configure a dedicated, highly available email alias (e.g., security@yourcompany.co.uk) and a specific Slack/Teams channel. Ensure these channels feed directly into your incident response tool or a monitored ticketing system, rather than a single person’s inbox which creates a bottleneck.
Minimum Requirement: A verified, functional SPOC reachable by all staff 24/7.
2. Define ‘Reportable Event’ Criteria
Control Requirement: Personnel must be able to identify what constitutes a security event.
Required Implementation Step: Publish a technical “Red Flag” guide. Explicitly list examples: unrecognised login alerts, system performance degradation, missing hardware, suspected phishing, or unauthorised physical entry. If staff don’t know what looks “wrong,” they won’t report it.
Minimum Requirement: A published list of event types included in the security induction.
3. Deploy an ‘Instant Reporting’ Button
Control Requirement: Make the reporting process as simple as possible to encourage speed.
Required Implementation Step: Install a “Report Phish” button in the email client (Outlook/Gmail) and an “Incident Report” shortcut on the desktop or intranet home page. Removing the friction of finding an email address increases the likelihood of reporting by over 400%.
Minimum Requirement: One-click reporting functionality deployed to 100% of managed endpoints.
ISO 27001 Toolkit
All the templates, tools, support and knowledge you need to do it yourself.
4. Implement ‘No-Blame’ Reporting Policy
Control Requirement: Encourage reporting without fear of reprisal.
Required Implementation Step: Formalise a “No-Blame” culture in the Employee Handbook. State clearly that employees will not be disciplined for reporting a mistake they made (e.g., clicking a link) as long as they report it immediately. Silence is the greatest risk to the ISMS.
Minimum Requirement: Policy language explicitly protecting self-reporting employees from immediate disciplinary action.
5. Force Automated System Event Forwarding
Control Requirement: Systems must automatically report events where human intervention is absent.
Required Implementation Step: Configure your SIEM (Security Information and Event Management) or EDR (Endpoint Detection and Response) to automatically generate tickets for critical alerts. Do not rely on a human to see a dashboard notification; the system must “report” the event to the IR team automatically.
Minimum Requirement: Automated alerting flow from core security infrastructure to the SPOC.
6. Create an Anonymous Reporting Channel
Control Requirement: Provide a path for whistleblowing on internal security violations.
Required Implementation Step: Set up an anonymous web form or a third-party whistleblowing line. This allows employees to report “insider threats” or senior management bypassing controls without fear of social or professional fallout.
Minimum Requirement: A functional, anonymous reporting mechanism that bypasses standard management lines.
7. Set Mandatory Reporting Timelines
Control Requirement: Events must be reported as quickly as possible.
Required Implementation Step: Define a “reporting window” in your policy (e.g., “All suspected events must be reported within 1 hour of discovery”). Use this window to measure the effectiveness of your awareness training during simulation exercises.
Minimum Requirement: Defined SLAs for reporting included in the Security Policy.
8. Establish Contractor Reporting Obligations
Control Requirement: Third parties must follow the same reporting rigour.
Required Implementation Step: Insert mandatory reporting clauses into all contractor and vendor Service Level Agreements (SLAs). They must use your SPOC to report any event that might impact your data, regardless of their internal processes.
Minimum Requirement: Signed contracts with third parties specifying the reporting channel and timeline.
9. Maintain a Security Event Log
Control Requirement: All reported events must be recorded for analysis.
Required Implementation Step: Maintain a master Security Event Register. This should capture the reporter, time of event, time of report, nature of the event, and the initial triage status. This log is the primary evidence for ISO 27001 auditors to prove the control is active.
Minimum Requirement: A timestamped register of all reported events (including “false positives”).
10. Implement ‘Feedback Loops’ for Reporters
Control Requirement: Confirm receipt and provide status updates to the reporter.
Required Implementation Step: Configure your ticketing system to send an automated “Thank You/Received” message immediately. If employees report things into a “black hole” and never hear back, they will stop reporting.
Minimum Requirement: Automated confirmation of receipt for every report submitted.
