ISO 27001 Control 6.4: Disciplinary Process

ISO 27001 Control 6.4: Disciplinary Process
How to Design a Fair, Practical Response to Security Breaches

ISO 27001 Control 6.4 Disciplinary process is about more than punishing people who break the rules. Done well, it gives you a clear, fair way to respond when someone ignores your information security policies – and it sends a strong signal that you take security seriously.

This guide walks through what ISO 27001 Control 6.4 is really asking for, and how to build a disciplinary process that works in the real world, not just on paper.

What ISO 27001 Control 6.4 Actually Requires

In simple terms, ISO 27001 Control 6.4 – Disciplinary process expects you to:

Have a formal, documented disciplinary process that covers information security breaches.
Make sure people know there are consequences for ignoring your information security policy and procedures.
Ensure the process is fair, consistent and legally compliant.
Use it to deter careless or malicious behaviour and to respond promptly when something goes wrong.

Most organisations already have an HR disciplinary policy. ISO 27001 Control 6.4 is really about making sure that:

Information security breaches are clearly covered as misconduct.
The process is linked to your incident management and investigation processes.
You can show evidence that you follow it in practice.

Step 1 – Link ISO 27001 Control 6.4 to Your HR Process

Start by looking at your existing HR disciplinary policy. You usually don’t need a completely separate ISO 27001 disciplinary process – you just need to make sure your current process covers security.

You should:

Check that information security breaches (e.g. sharing passwords, mishandling data, ignoring access rules) are listed as examples of misconduct or gross misconduct.
Make sure the policy references your information security policy and any key procedures (acceptable use, access control, remote working, data protection, etc.).
Confirm the policy is aligned with local employment law, any union agreements, and contractual obligations.

If HR owns the disciplinary policy (which is typical), agree how ISO 27001 responsibilities are built in, for example:

Security incidents are reported and logged.
HR and Information Security / IT review cases together where appropriate.
Outcomes are recorded and fed back into risk management and training.

Step 2 – Define What Counts as a Security Breach

To make ISO 27001 Control 6.4 work in practice, people need to understand what behaviour might trigger the disciplinary process.

Useful areas to cover include:

Access control breaches
– Sharing passwords or authentication tokens
– Letting unauthorised people use your account or devices
Data handling breaches
– Sending personal or confidential data to the wrong person
– Storing data in unapproved tools (personal email, consumer cloud, USB sticks)
– Printing or leaving documents unsecured
Technology misuse
– Ignoring patching or configuration standards
– Disabling security tools (endpoint protection, MFA, VPN, logging)
Deliberate or malicious acts
– Attempting to bypass security controls
– Theft, unauthorised disclosure, or sale of information

You don’t need an exhaustive list, but clear examples help staff and managers recognise when ISO 27001 disciplinary action might be appropriate.

Step 3 – Build a Graduated, Fair Disciplinary Process

ISO 27001 Control 6.4 expects a graduated response – you don’t treat a one-off honest mistake the same way as deliberate data theft.

When deciding what to do, consider:

Nature and gravity of the breach
– Was there actual harm (e.g. data breach, service outage, regulatory impact)?
– How sensitive was the information involved?
Intent
– Was it clearly malicious, negligent, or an honest mistake?
– Did the person try to hide it?
Frequency
– Is this a first incident or part of a pattern?
Training and clarity
– Had the person been trained on the relevant policy?
– Were expectations clearly communicated?

A typical ISO 27001 disciplinary process might include:

Informal coaching and feedback for low-impact, first-time, unintentional breaches.
Formal written warning for more serious or repeated issues.
Final written warning where behaviour continues or the impact is significant.
Dismissal or contract termination for gross misconduct or severe, intentional breaches.

The key for ISO 27001 is that:

The process is documented.
Decisions are recorded and justified.
Similar cases are treated consistently.

Step 4 – Integrate Investigation and Incident Management

Before disciplinary action, you must be confident that a breach has actually occurred.

Link ISO 27001 Control 6.4 to your:

Incident reporting process (how security incidents are raised).
Incident handling and investigation (how you gather facts, logs, screenshots, witness statements).
Root cause analysis and corrective actions (what you do to stop it happening again).

A simple flow could be:

Security incident reported.
Incident investigation confirms whether a policy breach took place.
Investigation pack shared with HR / management.
HR follows the disciplinary process if appropriate.
Lessons learned fed back into training, processes, and controls.

This helps you show an auditor that your disciplinary process is part of the wider ISMS, not a standalone HR document.

Step 5 – Protect Confidentiality and Treat People Fairly

ISO 27001 Control 6.4 expects your disciplinary process to be fair and respectful, not a witch hunt.

Make sure you:

Keep investigations and hearings confidential, sharing information only with those who need it.
Store any records of disciplinary action in line with data protection law and your retention rules.
Give individuals a chance to explain their side of the story.
Allow for appeal routes, as set out in your HR policy.

Auditors often look for evidence that the process balances accountability with fairness.

Step 6 – Communicate, Train, and Reinforce

A disciplinary process only supports ISO 27001 Control 6.4 if people know it exists and understand what it means.

Consider:

Including a clear section on information security responsibilities and consequences in:
- Induction training
- Staff handbook
- Annual security awareness training
Using realistic scenarios (anonymised) to show:
- What went wrong
- How the organisation responded
- What was changed afterwards
Reinforcing positive behaviour, not just punishment:
– Recognise teams who report incidents quickly
– Highlight good practice in newsletters or town halls

ISO 27001 is about building a security-conscious culture, not just issuing warnings.

Quick Implementation Checklist for ISO 27001 Control 6.4

Use this as a working list when you implement or review your disciplinary process:

ISO 27001 Control 6.4 is referenced in your ISMS documentation.
Your HR disciplinary policy explicitly covers information security breaches.
Examples of security-related misconduct are clearly documented.
The process includes a graduated set of responses (coaching → warnings → dismissal).
Incident management and investigation processes feed into disciplinary decisions.
Roles and responsibilities (HR, line manager, Information Security / IT) are clear.
Records of disciplinary actions are kept confidential and compliant with data protection.
Staff are informed and trained on the policy and its consequences.
The process is reviewed periodically to reflect lessons learned and legal changes.

Bringing It All Together

ISO 27001 Control 6.4 – Disciplinary process – is not just a checkbox. It’s a practical way to:

Show that you mean what you say in your information security policy.
Deter risky behaviour by making expectations and consequences clear.
Respond consistently and fairly when things go wrong.
Feed real incidents back into training, culture, and technical controls.

If you already have a solid HR disciplinary process, you’re not starting from scratch. Focus on making sure information security breaches are clearly covered, that the process ties into your incident handling, and that you can demonstrate how it works in practice when the auditor asks, “What happens here when someone breaks your security rules?”
