ISO 27001 A.6.4 - Disciplinary Process

Requirement

“A disciplinary process shall be formalized and communicated to take actions against personnel and other relevant interested parties who have committed an information security policy violation.”

Plain-language meaning

The organization needs a documented and communicated process for handling information security policy violations. People should know that violations can lead to action, and managers should know how to trigger the process fairly and consistently.

The process should not be informal punishment. It should be evidence-based, proportionate, documented, and aligned with HR, legal, contractual, and management practices.

Why this matters

If policy breaches have no consequence, standards decline. People learn that security rules are optional, exceptions become normal, and repeated non-compliance increases risk.

At the same time, a badly handled disciplinary process creates legal and employee-relations risk. Acting without enough evidence, treating similar cases differently, or bypassing the documented process can create unfair dismissal, personal-rights, contractual, or regulatory exposure.

Implementation guidance

1. Define the process

The process should define:

• what counts as an information security policy violation;
• who can initiate a disciplinary review;
• what evidence is required before the process starts;
• how severity is assessed;
• how cases are investigated;
• how fairness and consistency are maintained;
• how outcomes are documented;
• how appeals or dispute routes work where applicable;
• how follow-up actions are tracked to closure.

Security control non-compliance should be treated as policy non-compliance where policy requires compliance with controls.

2. Make the response proportionate

Different issues need different responses. A first-time mistake caused by unclear training is not the same as deliberate misuse, concealment, repeated violations, or malicious disclosure.

3. Communicate the process

Personnel and relevant interested parties should know:

• security policies are mandatory;
• violations can trigger disciplinary or contractual action;
• the process aims for fair and consistent treatment;
• evidence is required;
• corrective actions may include retraining, warning, access change, contract remedy, or stronger action depending on severity.

Communication can happen through onboarding, policy acknowledgement, training, contractor onboarding, and management briefings.

4. Link sanctions with positive reinforcement

Discipline should not be the only behavior tool. Compliance incentives, recognition, good reporting behavior, and training reinforcement can support a healthier security culture.

This matters because fear-only programs often suppress incident reporting and make security issues harder to see.

5. Coordinate security, HR, legal, and management

Typical ownership:

• security provides the policy violation facts and technical/security evidence;
• HR owns employee disciplinary procedure;
• legal advises on enforceability and fairness risk;
• managers support fact-finding and corrective action;
• procurement or vendor management handles third-party contractual consequences.

Audit guidance

Auditors should verify that the disciplinary process is formalized, communicated, and used consistently when information security policy violation criteria are met.

Audit testing should include:

• disciplinary policy or HR procedure references to information security violations;
• security policy language requiring control compliance;
• awareness or onboarding evidence showing communication;
• incident records and policy violation cases;
• criteria for disciplinary action;
• evidence thresholds before initiation;
• case follow-up records through completion;
• interviews with HR, security, managers, and sampled personnel;
• evidence that similar cases are treated consistently;
• evidence that third-party or contractor violations have a defined route.

The auditor should challenge both extremes: no action despite clear criteria, and action without sufficient evidence or process discipline.

Evidence examples

Strong evidence

• Process is documented, approved, and communicated.
• Policy states that information security policy/control violations can lead to action.
• Criteria define when disciplinary action is considered.
• Action starts only after sufficient evidence of breach or non-compliance.
• Outcomes are proportionate to severity, intent, impact, and history.
• Similar cases are handled consistently.
• Follow-up actions are tracked to closure.
• Contractors and third parties are covered through appropriate contractual or vendor-management routes.

Weak evidence

• Generic HR procedure with no security-policy trigger.
• Managers handle security violations informally.
• No evidence threshold before disciplinary action.
• Similar cases receive inconsistent treatment.
• Incidents meet criteria but no disciplinary review occurs.
• Follow-up action is not completed or recorded.
• Personnel do not know the process exists.

KB-ready summary

• A.6.4 requires a formalized and communicated disciplinary process for information security policy violations.
• The process should deter, correct, and respond to non-compliance.
• Action should be fair, consistent, evidence-based, and proportionate.
• Security policy should make control compliance mandatory so control breaches can be treated as policy breaches.
• The process should cover relevant personnel and interested parties, including third parties where applicable.
• Audit evidence should show communication, triggers, sufficient evidence, case handling, follow-up, and closure.
