Pearson ASIS-PSP New Attempt

System integration combines technology, procedures, and people—i.e., personnel—to create a cohesive and effective security solution. Personnel are essential for operating, monitoring, and responding to events within the system.

A (Safety) and D (Management) are broader organizational functions.

B (Equipment) is a part of the technology component, already implied.

The statement is incorrect. The correct definitions are:

Libel is written defamation—false and damaging statements published in writing or other fixed mediums.

Slander is oral defamation—spoken false statements meant to damage someone’s reputation.

So, libel is not oral; slander is.

The correct answer is C. environmental and degradation factors.

In PSP physical security design, lighting is treated as a structural security countermeasure, and the ASIS PSP Body of Knowledge includes knowledge of lighting, electronic security systems, performance requirements, and security system design capacities.

A 4:1 light-to-dark ratio means the brightest area should not be more than four times brighter than the darkest area within the assessed scene. This provides relatively even illumination for guards and video assessment systems. In physical protection system guidance, the light-to-dark ratio directly affects the ability to assess a scene; very high ratios create dark blind spots, while a lower ratio such as 4:1 greatly reduces those blind spots.

The reason 4:1 is used as the preferred design goal is that lighting systems degrade over time due to environmental and maintenance-related factors such as lamp aging, dirt on fixtures, weather effects, dust, damaged lamps, vegetation growth, and surface reflectance changes. Guidance on security camera lighting states that lighting may be designed for a 4-to-1 ratio to allow for degradation over time, while a 6-to-1 ratio is still used as a practical maximum to avoid areas becoming too dark or too bright for assessment.

The other options are not the best answer:

A. High surface reflection may help contrast, but it is not the reason for selecting a 4:1 design goal.

B. High aspect ratio is not a security lighting design objective in this context.

D. Reflected glare reduction is important, but the 4:1 ratio is mainly selected to maintain usable illumination despite environmental and degradation factors.

Therefore, the correct answer is C. environmental and degradation factors.

An initial threat or hazard evaluation must include an assessment of how likely each threat is to occur. This probability, when combined with impact analysis, forms the foundation for risk assessments. Understanding likelihood allows prioritization of mitigation strategies.

A (Estimate costs) and C (Develop business case) are later steps.

D (Develop response plan) comes after risk characterization.
