Certified Cybersecurity Technician Network Security Controls - Physical Controls Exam 212-82 Lighting System Adequate lighting should be provided inside, outside, and at the entrance of the building which helps in seeing long distances during security patrols Adequate lighting will discourage intruders from entering the premises and concealing behind stones, bushes, trees, etc. Types of lighting systems: @ v Continuous v Standby v" Movable v' Emergency Lighting System Security lighting is an important aspect of the physical security of a facility. If an organization has not implemented an adequate lighting system in and around its premises, the function or performance of all other security measures can be drastically degraded. For example, if the organization does not have lighting at rear corners, near bushes, plants, parking, and near surveillance cameras, then it is difficult to find people or objects hidden in these locations. With poor lighting, it is difficult to identify people entering the premises, and an intruder may act as an employee or use tricks to circumvent the security systems. The lighting systems to install in an area depend on the layout and sensitivity of the area. Alternate power systems such as generators should be installed to handle power failures and emergencies. = Continuous lighting: Continuous lighting refers to fixed sets of lights arranged such that they provide continuous lighting to a large area throughout the night. = Standby lighting: Standby lighting is used whenever any suspicious activity is detected by security personnel or by an alarm system. These systems operate either manually or automatically. = Movable lighting: Movable lighting is a manually controlled lighting system that provides lighting at night or only when needed. These systems are normally used as an extension of a continuous or standby lighting system. = Emergency lighting: Emergency lighting is used mainly during power failures or when other regular lighting systems fail to operate properly.

Power outages could impact the ability to provide IT services as expected as well as the ability to provide physical security. Power spikes, surges, or blackouts could result in excessive or insufficient power and could damage equipment. Consider the following security measures to handle blackouts or power outages. = Be prepared for power fluctuations. = Use an uninterruptible power supply (UPS) to manage power outages. = Safeguard systems from environmental threats. = Protect systems from the adverse effects of static electricity at a workplace. = Use plugging equipment properly. A UPS allows computers to function properly during a power failure. It protects computers during fluctuations in the power supply as well. A UPS contains a battery that senses power fluctuations in the primary device. Users need to save all their data when the UPS senses a power fluctuation. The operator must provide procedures to follow at the time of power loss. A UPS is commonly used to protect computers, data centers, telecommunication equipment, etc. The following are the different types of UPS include. = Standby: Standby UPSes are the most commonly used type of UPS for personal computers. A standby UPS is an offline battery backup facilitating the maintenance of Module 06 Page 655 Certified Cybersecurity Technician Copyright © by EG-Council All Rights Reserved.

A standby power supply contains AC-DC circuitry that connects to the UPS during a power fluctuation. * Line interactive: Most commonly used for small business, web, and departmental servers, line interactive mainly handles continuous power fluctuations. This method of power supply needs very little battery usage. = Standby online hybrid: Most commonly used for server rooms, standby online hybrid UPSes are mainly used to supply power below 10 kVA. They are connected to the battery during a power failure. = Stand by output. A supply to becomes = Double conversion online: Generally used in environments where electrical isolation is necessary, a double conversion online UPS is used to supply power above 10 kVA. It Ferro: In standby battery unstable this type of UPS, a Ferro resonant transformer is used for filtering the Ferro UPS provides ample time for switching from the main power power. This type of UPS is no longer commonly used because it when handling a modern computer’s power load. provides an ideal electric output presentation, but its power components are subject to continuous wear, reducing its dependability. large current load. = It exhibits a transfer time only during a Delta conversion online: A delta conversion online UPS can be useful when complete isolation and/or direct connectivity is required. It contains an inverter that supplies the load voltage. It can be used to supply power in the range between 5 kVA and 1 MW. It controls the power input performance and charging of the UPS battery.
