What is a Security Policy?
A security policy is the set of agreements, procedures and measures through which an organisation systematically safeguards the safety of employees, installations and processes. It forms the foundation of safe working practices, both physical and digital (OT/IT).
A sound security policy complies with the Working Conditions Act, is aligned with the organisation’s risks, and is visibly embedded in day-to-day work.
🧠 What does a security policy cover?
- Vision and accountability
- Safety as a core value in policy and culture
- Designated safety officers (e.g. prevention officer, HSE manager)
- Risk inventory
- Carried out via an RI&E (risk inventory and evaluation)
- Identification and prioritisation of hazards
- Preventive measures
- Technical: guarding, emergency stops, Lock-out Tag-out, PPE
- Organisational: work permits, LMRA, training
- Procedural framework
- Work instructions, emergency plans, evacuation procedures
- Reporting and follow-up structure for incidents and near misses
- Continuous improvement
- Audit cycle: measure, adjust, train
- Safety observations and evaluations
🏭 Application in industrial environments
- Machines and processes (manufacturing, chemicals, energy, food)
- Technical installations (electrical, hydraulic, pneumatic)
- Working at heights, in confined spaces or in explosive environments (ATEX)
- Working with PLC, Drives, control cabinets and networks (OT networks)
A security policy must align with day-to-day practice, drawing on input from operators, technicians and engineers.
🔍 Key elements of a security policy
| Element | Explanation |
|---|---|
| RI&E | Legally required, forms the basis for all measures |
| Training | Raises safety awareness across all staff |
| Lock-out Tag-out | Prevents energy release during maintenance |
| Work permit | Formal approval for high-risk tasks |
| PPE | Personal protection against physical hazards |
| LMRA | Final risk check before work begins |
| Incident reporting | Reporting and analysis of incidents and near misses |
| Audit | Periodic review of compliance and effectiveness |
A security policy is only effective when it lives within the organisation.
🔐 Security considerations
- Security policy also covers OT cybersecurity (e.g. network segmentation, patch management, Access Control)
- Mandatory document for certifications (e.g. ISO 45001, VCA, BRL)
- Embedded within the management system or ISMS
- Essential for safe collaboration with contractors, suppliers and third parties
A deficient security policy can lead to fines, liability and personal injury.
📌 In summary
A security policy is the backbone of a safe working environment. It provides structure, accountability and continuous improvement of both physical and digital safety.
