ISO 27001 Annex A 6.4: Disciplinary Process
What is ISO 27001 Annex A 6.4?
ISO 27001 Annex A 6.4 requires the organization to establish and communicate a disciplinary process to address information security violations by personnel.
The purpose is to ensure that information security violations are handled in a:
- Consistent manner.
- Fair manner.
- Proportionate manner.
- Documented manner.
- Legally appropriate manner.
The disciplinary process should apply when personnel violate established information security requirements, policies, procedures or contractual obligations.
Simple explanation
Employees should know what happens when security rules are deliberately or repeatedly violated, and the organization should handle violations consistently and fairly.
A disciplinary process does not mean that every security mistake should result in punishment.
The organization should distinguish between:
- Accidental mistakes.
- Lack of awareness.
- Negligence.
- Repeated non-compliance.
- Deliberate violations.
- Malicious or fraudulent activity.
The response should be appropriate to the circumstances and applicable employment/legal requirements.
Why is Annex A 6.4 Important?
Organizations establish information security policies and procedures to protect:
- Customer information.
- Personal data.
- Source code.
- Intellectual property.
- Financial information.
- Credentials.
- Production systems.
- Confidential business information.
However, policies are only effective when people are expected to follow them.
Without a defined disciplinary process, an organization may handle similar violations differently.
For example:
Employee A
Shares confidential information accidentally → informal coaching.
Employee B
Repeatedly ignores the same security requirement after training → formal corrective action.
Employee C
Deliberately attempts to bypass access controls → potentially serious disciplinary action, subject to investigation and applicable requirements.
A defined process helps ensure that these situations are handled systematically rather than arbitrarily.
Benefits of A.6.4
A disciplinary process can help the organization:
- Reinforce information security responsibilities.
- Establish clear expectations.
- Promote consistent treatment.
- Address repeated non-compliance.
- Deter intentional violations.
- Support accountability.
- Provide evidence of governance.
- Reduce arbitrary decision-making.
- Connect HR processes with the ISMS.
Simple principle
Security requirements should have accountability behind them, but the response should be appropriate to the nature and circumstances of the violation.
What Does Annex A 6.4 Require?
The organization should have a process for dealing with information security violations.
The process should be:
Fair
Employees should have an opportunity to understand and respond to the issue, subject to applicable organizational and legal processes.
Consistent
Similar circumstances should generally be handled using the same established framework.
Proportionate
The response should consider the seriousness and circumstances of the violation.
Communicated
Personnel should know that violations of security requirements may result in disciplinary action.
Legally Appropriate
The process should comply with applicable:
- Employment laws.
- Labor requirements.
- Contracts.
- Internal HR requirements.
- Privacy requirements.
- Due-process requirements where applicable.
What Can Constitute a Security Violation?
Examples include:
Access Violations
- Sharing credentials.
- Attempting to access unauthorized systems.
- Bypassing access controls.
- Using another person’s account.
Information Handling Violations
- Sharing confidential information without authorization.
- Sending customer information to an unauthorized recipient.
- Storing sensitive information in an unauthorized location.
- Removing confidential documents without authorization.
Device and Technology Violations
- Installing unauthorized software.
- Disabling required security controls.
- Connecting unauthorized devices.
- Circumventing endpoint protection.
Policy Violations
- Repeatedly ignoring security policies.
- Failing to complete mandatory security requirements.
- Deliberately violating acceptable-use rules.
Incident Reporting Violations
- Failing to report a known security incident.
- Concealing a security incident.
- Delaying reporting despite clear requirements.
Deliberate Misconduct
Potential examples include:
- Deliberate unauthorized disclosure.
- Deliberate destruction of information.
- Intentional credential misuse.
- Fraudulent activity.
- Deliberate attempts to circumvent security controls.
The organization should investigate the circumstances before deciding how to respond.
Accidental Mistake vs. Deliberate Violation
This distinction is particularly important.
Not every security incident should become a disciplinary case.
For example:
Scenario 1 — Accidental
An employee accidentally sends a document to the wrong internal employee.
Possible response:
Contain → Report → Assess → Coach → Improve
Scenario 2 — Negligence
An employee repeatedly stores confidential files in an unauthorized location despite previous training and warnings.
Possible response:
Investigate → Document → Correct → Formal action if appropriate
Scenario 3 — Deliberate
An employee intentionally attempts to access systems they are not authorized to use.
Possible response:
Investigate → Restrict access where appropriate → Follow disciplinary process → Take appropriate action
The exact response depends on the organization’s policies, employment arrangements, applicable law and facts of the case.
Activities Required to Implement A.6.4
Step 1 — Define Information Security Violations
Identify the types of behavior that may constitute security violations.
Examples:
- Policy violations.
- Unauthorized access.
- Data disclosure.
- Credential misuse.
- Security-control bypass.
- Failure to report incidents.
- Deliberate security misconduct.
These definitions can be documented in an HR or information security policy.
Step 2 — Define the Disciplinary Process
A simple process may look like:
Security violation identified
↓
Report to appropriate function
↓
Initial assessment
↓
Investigation
↓
Gather relevant evidence
↓
Determine facts
↓
Employee response / appropriate review
↓
Decision
↓
Disciplinary or corrective action, if appropriate
↓
Document outcome
↓
Follow-up
The organization should avoid automatically treating an allegation as proof of misconduct.
Step 3 — Define Roles and Responsibilities
Clearly define who is responsible for handling cases.
For example:
| Role | Responsibility |
|---|---|
| Employee | Report suspected violation |
| Manager | Escalate potential violation |
| Information Security | Assess security impact |
| HR | Manage personnel/disciplinary process |
| Legal | Provide legal guidance where required |
| Management | Approve significant actions where applicable |
| IT/Security | Preserve relevant technical evidence |
The exact structure will depend on the size of the organization.
Step 4 — Communicate the Process
Employees should know:
- Security violations may result in disciplinary action.
- Which policies they are expected to follow.
- How violations are reported.
- Who manages disciplinary matters.
- That investigations will be handled according to applicable procedures.
This can be communicated through:
- Employee handbook.
- Employment documentation.
- Information Security Policy.
- HR Policy.
- Security Awareness Training.
Step 5 — Ensure Evidence Is Preserved
Where a security violation may require investigation, relevant evidence should be preserved appropriately.
Examples:
- System logs.
- Access logs.
- Email records.
- Endpoint records.
- Ticket history.
- Security alerts.
- Access review records.
- Relevant communications.
Evidence handling should be consistent with applicable privacy, legal and organizational requirements.
This connects A.6.4 with A.5.28 — Collection of Evidence.
Step 6 — Investigate the Circumstances
The organization should determine:
- What happened?
- When did it happen?
- Which policy or requirement was involved?
- Was the behavior accidental or intentional?
- Was the employee aware of the requirement?
- Was training provided?
- Was there a legitimate business reason?
- Was there previous non-compliance?
- What was the security impact?
- Is there evidence of malicious intent?
- Are other systems or people affected?
This helps avoid making disciplinary decisions based solely on assumptions.
Step 7 — Determine Appropriate Action
Possible responses may include:
- Coaching.
- Additional training.
- Formal warning.
- Corrective action.
- Restriction of access.
- Other disciplinary measures permitted by applicable policies and law.
- Termination where justified and legally appropriate.
Not every violation requires the same response.
Step 8 — Record the Outcome
Maintain appropriate records of:
- Case identification.
- Date.
- Nature of violation.
- Investigation.
- Evidence considered.
- Decision.
- Corrective or disciplinary action.
- Approvals.
- Follow-up.
Personnel records should be protected because they may contain sensitive information.
Startup Example
Consider a 50-person SaaS company.
The company has an Acceptable Use Policy that prohibits employees from installing unauthorized software on company-managed devices.
An employee repeatedly installs unauthorized software despite:
- Security awareness training.
- Policy acknowledgement.
- Previous notification.
The security team identifies the issue through endpoint monitoring.
Process
Security alert
↓
Initial assessment
↓
Confirm unauthorized software
↓
Review policy and employee history
↓
Notify appropriate manager/HR
↓
Investigate circumstances
↓
Employee provides explanation
↓
Determine appropriate corrective/disciplinary response
↓
Document outcome
↓
Additional training or controls if required
The company does not simply punish the employee based on an automated alert.
It follows a defined process.
Another Example: Accidental Data Disclosure
An employee accidentally sends a customer report to the wrong customer.
The employee immediately reports the mistake.
The organization:
- Assesses the incident.
- Attempts to contain the disclosure.
- Determines what information was exposed.
- Evaluates applicable contractual/privacy obligations.
- Records the incident.
- Identifies why the mistake occurred.
- Provides additional training if appropriate.
The fact that a security incident occurred does not automatically mean that disciplinary action is required.
The organization should consider the circumstances, intent, negligence, previous behavior and applicable policies.
This distinction is important for a mature security culture.
Startup-Focused Quick Summary
A startup does not need an unnecessarily complicated disciplinary framework.
A practical model is:
1. Define
Document security violations and expected behavior.
2. Communicate
Tell employees that security violations may result in appropriate corrective or disciplinary action.
3. Investigate
Determine what actually happened.
4. Evaluate
Consider:
- Intent.
- Impact.
- Circumstances.
- Previous behavior.
- Training.
- Policy requirements.
5. Act
Apply an appropriate response.
6. Record
Maintain appropriate evidence.
7. Improve
Address the underlying security weakness.
Simple startup principle
Do not create a punishment-first culture. Create an accountability-and-learning process that distinguishes mistakes from deliberate violations.
Example Security Violation Classification
A startup can use a simple classification model.
| Category | Example | Possible Response |
|---|---|---|
| Accidental | Wrong recipient | Coaching / training / incident response |
| Minor non-compliance | Occasional policy deviation | Reminder / corrective action |
| Repeated non-compliance | Repeated violation after training | Formal corrective action |
| Serious violation | Unauthorized access attempt | Formal investigation/action |
| Deliberate misconduct | Intentional data misuse | Appropriate disciplinary/legal action |
These are illustrative categories, not mandatory ISO classifications.
The organization should define its own framework according to its circumstances and applicable requirements.

Relationship Between Security Incident and Disciplinary Case
These are not the same thing.
Security Incident
Focuses on:
What happened to information security?
Example:
Customer information was accidentally disclosed.
Disciplinary Process
Focuses on:
Did a person violate an established requirement, and what personnel response is appropriate?
An incident can occur without misconduct.
Similarly, a policy violation may occur without becoming a security incident.
For example:
An employee installs unauthorized software, but no security incident occurs.
It may still constitute a policy violation.
Audit Evidence for A.6.4
An auditor may review:
Policies
- Disciplinary Policy.
- Information Security Policy.
- HR Policy.
- Acceptable Use Policy.
- Employee Code of Conduct.
Procedures
- Disciplinary Procedure.
- Security Violation Investigation Procedure.
- Incident Escalation Procedure.
Communication
- Employee handbook.
- Employment terms.
- Security awareness training.
- Policy acknowledgement.
Evidence
Where appropriate and legally permissible:
- Security violation records.
- Investigation records.
- Corrective action records.
- Disciplinary case records.
- Access restriction records.
- Training records.
- Management approvals.
Auditors generally do not need unrestricted access to confidential personnel files. Organizations should protect personal and sensitive information and provide appropriate evidence demonstrating that the process exists and operates.
Audit Checklist for A.6.4
Before an ISO 27001 audit, ask:
- Is there a documented disciplinary process?
- Does it cover information security violations?
- Are employees informed that security violations may result in disciplinary action?
- Are security responsibilities established through A.6.2?
- Are security policies communicated through A.6.3?
- Are potential violations investigated?
- Is the process fair and consistent?
- Is the response proportionate to the circumstances?
- Are relevant technical or documentary records preserved?
- Are HR and security responsibilities clearly defined?
- Are disciplinary records appropriately protected?
- Are repeated violations addressed?
- Are corrective actions tracked?
- Are lessons from recurring violations fed back into training or controls?
- Can the organization demonstrate that the process is operational?
Common Mistakes in Implementing A.6.4
1. No documented process
The organization says:
“HR handles these issues.”
But there is no documented process connecting security violations with HR procedures.
2. Punishing every mistake
An employee accidentally clicks a phishing link and immediately reports it.
Treating the employee as a disciplinary problem may discourage future reporting.
A better approach is to investigate, contain, learn and improve, while reserving disciplinary action for circumstances where it is appropriate.
3. No action for repeated violations
The opposite problem is also possible.
An employee repeatedly violates security requirements despite:
- Training.
- Warnings.
- Clear policies.
The organization should have a mechanism for escalating repeated non-compliance.
4. No evidence
The organization has a disciplinary policy but cannot demonstrate that security violations are actually handled.
5. Security team makes HR decisions independently
Security may identify the technical violation, but disciplinary decisions should follow the organization’s established HR/legal process.
6. No investigation
A security alert should not automatically be treated as proof of employee misconduct.
The organization should establish the facts.
7. Inconsistent treatment
Two similar security violations are handled completely differently without a documented reason.
This can create fairness and governance problems.
8. Ignoring privacy
Disciplinary records can contain sensitive employee information.
They should be appropriately protected, accessed only by authorized personnel and retained according to applicable requirements.
9. Focusing only on punishment
Repeated violations may indicate:
- Poor training.
- Unclear policies.
- Poor system design.
- Excessive privileges.
- Confusing procedures.
- Missing technical controls.
The organization should also address the underlying cause.
Practical Startup Implementation Model

Simple formula
Define → Communicate → Detect → Investigate → Evaluate → Act → Document → Improve
Policy vs. Process vs. Evidence
| Category | Example |
|---|---|
| Policy | Disciplinary Policy |
| Policy | Information Security Policy |
| Policy | Code of Conduct |
| Process | Disciplinary Procedure |
| Process | Security Violation Investigation Procedure |
| Process | Security Incident Escalation Procedure |
| Process | Corrective Action Procedure |
| Evidence | Policy acknowledgement |
| Evidence | Security violation record |
| Evidence | Investigation record |
| Evidence | Corrective action record |
| Evidence | Disciplinary case record |
| Evidence | Access restriction record |
| Evidence | Training record |
| Evidence | Follow-up record |
Simple rule
Policy establishes expected behavior.
Training creates awareness.
The disciplinary process establishes how violations are handled.
Evidence demonstrates that the process operates.
Relationship with Other ISO 27001 Controls
A.6.4 works as part of the broader personnel security lifecycle.
| Control | Relationship |
|---|---|
| A.6.1 | Screening |
| A.6.2 | Security responsibilities in employment terms |
| A.6.3 | Security awareness, education and training |
| A.6.4 | Disciplinary process |
| A.6.5 | Responsibilities after termination or change |
| A.6.6 | Confidentiality/NDA |
| A.6.7 | Remote working |
| A.6.8 | Security event reporting |
| A.5.28 | Collection of evidence |
| A.5.36 | Compliance with security policies |
| A.5.34 | Privacy and protection of PII |
A.6.3 vs. A.6.4
These controls work together but serve different purposes.
A.6.3
Awareness and training
“Does the person understand the security requirement?”
A.6.4
Disciplinary process
“What happens when an established security requirement is violated?”
For example:
Employee receives security training
↓
Employee acknowledges policy
↓
Employee violates policy
↓
Organization investigates
↓
Appropriate response
This demonstrates a complete accountability cycle.
A.6.4 and A.6.8
These controls can also interact during a security event.
A.6.8
Employee reports:
“I think my account has been compromised.”
This is a security event reporting requirement.
The organization then investigates the event.
If evidence shows the employee deliberately shared credentials in violation of policy, the organization may separately consider the A.6.4 disciplinary process.
Therefore:
Reporting a security incident is not itself misconduct.
In fact, encouraging timely reporting is an important part of a healthy security culture.

Questions an Auditor May Ask
General
“What happens when an employee violates an information security policy?”
“Where is your disciplinary process documented?”
Communication
“How are employees informed that security violations may lead to disciplinary action?”
Investigation
“How do you distinguish an accidental mistake from deliberate misconduct?”
Evidence
“Can you show evidence that the disciplinary process has been applied?”
Consistency
“How do you ensure security violations are handled consistently?”
Privacy
“How are disciplinary records protected?”
Improvement
“If you see repeated security violations, how do you address the underlying cause?”
Startup-Focused Final Takeaway
ISO 27001 Annex A 6.4 is about establishing accountability for information security violations.
It does not mean:
“Punish anyone who makes a security mistake.”
Instead, a mature approach is:
Define expectations
↓
Communicate them
↓
Train employees
↓
Identify violations
↓
Investigate fairly
↓
Understand the circumstances
↓
Apply an appropriate response
↓
Document the outcome
↓
Improve security
For startups, the most important thing is to have a clear, documented and proportionate process rather than a complicated HR framework.
The key questions for A.6.4 are:
“Do employees know that information security violations can have consequences?”
“Do we have a fair and consistent process for investigating and addressing violations?”
“Can we demonstrate that the process is applied appropriately while protecting employee privacy?”
A strong implementation connects employment responsibilities (A.6.2) → awareness and training (A.6.3) → accountability (A.6.4) → post-employment responsibilities (A.6.5) to create a complete personnel-security lifecycle.
