1. Link Discipline Directly to Employment Contracts
Control Requirement: Ensure the legal basis for disciplinary action is established prior to any incident.
Required Implementation Step: Review standard employment contracts and the Employee Handbook. Insert a specific clause stating that “Violation of Information Security Policies (including data theft, password sharing, and unauthorised access) constitutes misconduct or gross misconduct.” Without this contractual link, enforcing dismissal for a security breach is legally hazardous.
Minimum Requirement: Signed contracts explicitly referencing the ISMS policies as a condition of employment.
2. Define ‘Security Gross Misconduct’
Control Requirement: Distinguish between accidental error and malicious/negligent behaviour.
Required Implementation Step: Update the Disciplinary Policy to list specific security examples of Gross Misconduct (immediate dismissal). This list should include: disabling antivirus/EDR, intentional data exfiltration, installing pirate software, and sharing credentials with external parties.
Minimum Requirement: A published list of “Zero Tolerance” security behaviours.
3. Establish a Forensic Investigation Protocol
Control Requirement: Ensure evidence used in disciplinary hearings is accurate and admissible.
Required Implementation Step: Create a “Preservation of Evidence” procedure for HR and IT. When a breach is suspected, IT must not “poke around” and alter timestamps. They must capture immutable logs, take disk images if necessary, and maintain a Chain of Custody to prove the employee committed the act.
Minimum Requirement: A documented procedure for securing digital evidence before a disciplinary hearing begins.
DO IT YOURSELF
ISO 27001
All the templates, tools, support and knowledge you need to do it yourself.
4. Create a Graduated Sanction Matrix
Control Requirement: Ensure the punishment fits the crime and is applied consistently.
Required Implementation Step: Develop a matrix guiding HR on sanctions. For example: Unlocked screen = Verbal Warning; Phishing Failure (Repeat) = Written Warning; Data Leak = Final Written Warning or Dismissal. This removes subjectivity and accusations of bias.
Minimum Requirement: A “Security Sanctions Matrix” approved by Legal and HR.
5. Enforce Immediate Access Suspension
Control Requirement: Prevent further damage during the investigation.
Required Implementation Step: Configure a “Suspension Workflow” in your Identity Provider (Okta/AD). If an employee is under investigation for a serious security breach, their accounts must be disabled (not deleted) immediately before they are notified of the meeting, to prevent revenge data deletion.
Minimum Requirement: Documented ability to revoke access within 15 minutes of an HR trigger.
6. Mandate HR and Security Collaboration
Control Requirement: Ensure technical facts are understood by non-technical adjudicators.
Required Implementation Step: Formalise the role of the CISO or Security Lead in disciplinary hearings. Their role is to present the technical facts (e.g., “The logs prove the user bypassed the proxy”) to HR, ensuring the decision is based on reality, not the employee’s technical obfuscation.
Minimum Requirement: Meeting minutes showing Security representation in breach-related disciplinary hearings.
7. Clarify Contractor and Third-Party Penalties
Control Requirement: Apply disciplinary logic to non-employees.
Required Implementation Step: Update Supplier and Contractor agreements. Define the process for “Removing a Representative”. If a contractor breaches security, you cannot “fire” them in the employment sense, but you must have the contractual right to terminate their specific access and demand a replacement immediately without penalty.
Minimum Requirement: “Right to Remove” clauses in all third-party access contracts.
8. Implement ‘Fair Process’ Safeguards
Control Requirement: Protect the organisation against wrongful dismissal claims.
Required Implementation Step: Ensure the process includes a right to appeal and a right to review the digital evidence. The accused employee must be shown the log data (redacted if necessary) supporting the claim. Secret evidence creates legal liability.
Minimum Requirement: Evidence that the accused was given the opportunity to refute the technical findings.
9. Document the Decision Logic
Control Requirement: Maintain an audit trail of the disciplinary outcome.
Required Implementation Step: Retain a secure file linking the Incident Report (the breach) to the Disciplinary Outcome (the punishment). If an auditor asks, “What did you do about the data leak in May?”, you must show the chain from detection to the final warning issued.
Minimum Requirement: A cross-referenced log of Security Incidents vs. HR Disciplinary Records.
10. Communicate Redacted Outcomes (Deterrence)
Control Requirement: Use the process to deter future non-compliance.
Required Implementation Step: Without naming names, communicate the consequences of breaches to the wider staff. E.g., “Last month, an individual was dismissed for transferring company data to a personal USB drive.” This turns a private HR matter into a powerful cultural reinforcement.
Minimum Requirement: Periodic “Security Updates” to staff that mention enforcement actions taken.
