Electronic Security Design Guides

Designing Electronic Security Systems

Successful electronic security systems are the result of a structured design process that begins with operational requirements, considers risk and performance, and delivers solutions that remain effective throughout their operational life.

The Design Guides provide practical, vendor-neutral guidance for designing electronic security systems across a wide range of disciplines. Whether designing a single system or an integrated security solution, these guides focus on engineering principles rather than individual manufacturers or technologies

Operational Objectives

Successful security system design begins with a clear understanding of the operational outcomes the organisation is trying to achieve. Technologies should be selected to satisfy defined operational requirements rather than dictate them. Every design decision should support the organisation’s business objectives, operational requirements and identified risks

The first stages of the Security Design Process establish these requirements by identifying business objectives, assessing risk and defining the operational outcomes that the completed system must deliver. This provides the foundation for every subsequent design decision.

Business Objectives

Every access control system should support one or more organisational objectives, such as protecting people, safeguarding assets, controlling access to sensitive areas or improving operational efficiency. These objectives establish why the system is required and define what success looks like.

Threats and Risks

Understanding the threats, vulnerabilities and operational risks facing the organisation ensures that access control measures are proportionate to the environment they are intended to protect. Higher-risk areas may require stronger authentication, increased resilience or additional security measures.

See: Security Design Process – Assess Risk

Operational Requirements

Operational requirements define who should be able to access each area, when access should be permitted and under what conditions. Different buildings, zones and doors will often require different access strategies depending on their operational purpose and security risk.

See: Security Design Process – Operational Requirements

Stakeholder Requirements

The design process should consider the needs of everyone who will own, operate, maintain or rely upon the system, including security personnel, facilities management, IT teams, operational departments, human resources and senior decision-makers.

See: Security Design Process – Define

Success Criteria

Clear acceptance criteria should be established before detailed design begins. Success should be measured against operational outcomes, ensuring authorised users can move efficiently while preventing unauthorised access and supporting the organisation’s wider security objectives.

Design Philosophy

Although each discipline has its own technical requirements, successful security projects share common design principles.

Every system should:

  • Begin with clearly defined operational requirements.
  • Address identified risks rather than perceived threats.
  • Achieve measurable operational outcomes.
  • Be scalable, resilient and maintainable.
  • Integrate appropriately with wider building systems.
  • Be validated against the original design objectives.
