System Defenses
The system defense mechanisms will protect an organization’s assets, people, and information from unauthorized access or possible threats.
Various types of system defense mechanisms are discussed in this article that include asset tracking, port controls, and environmental controls like electricity management, HVAC systems, fire detection, personnel safety training, fire suppression methods, and types of fire suppression agents.
Asset Tracking
Asset tracking is basically the process of systematic monitoring and inventory management of the organization’s physical assets throughout their lifecycle. It has involved tracking asset location, status, and usage along with core assets like equipment, vehicles, and inventory. The organization can optimize asset utilization, reduce instances of theft or loss, and thereby improve general operational efficiency through technologies such as RFID, GPS, and barcode scanners.
Mechanism
Asset tracking typically involves tagging assets with unique identifiers monitored through software. This will allow a business to gain current information on asset performance and condition to better make decisions and create strategies.
For example, RFID tags can be attached to tools and equipment in a factory. Here, during the various production stages, the whereabouts and usage of such assets can be tracked in real time to ensure that tools are utilized effectively and misplaced as little as possible.
Port Controls
Port control plays a significant role in granting access to such areas within an organization, which are deemed to be secure. This is particularly true regarding those areas that house sensitive materials or equipment. Efficient port control measures act to bar unauthorized entry and guard against possible threats.
Mechanism
Control may be through physical barriers such as gates and fences, and/or through electronic ways of access control authenticated against a database. Systems may also include monitoring equipment such as CCTV to view points of entry in real time.
For instance, an airport may introduce a strict port control in its baggage-handling area where all the personnel are required to have some kind of biometric identification at the entrance of the sensitive area. This staff would guarantee that no tampering or theft of the baggage takes place.
Environmental Controls
The role played by environmental controls is that of keeping the facility safe and secure. These controls handle critical systems in electricity, heating, ventilation, air conditioning commonly known as HVAC, and fire detection systems.
Electricity
The electrical system in any facility needs to be managed appropriately to ensure that the facility remains safe and functional. This relates to maintenance, monitoring of the facility for potential hazards, and backup power.
Mechanism
Systems should be designed to have redundancy and safety features to prevent failures, which include surge protectors, UPS, and routine inspections to find potential problems.
Example: UPS systems in a data center help make sure that there is backup power during an outage so the critical systems operate and data will not be lost.
HVAC
HVAC systems are quite critical in ensuring comfort and safety for a facility. If the HVAC systems are well designed and maintained, they can easily be used to regulate temperature and humidity and even quality.
Mechanism
The HVAC system needs checking and maintenance periodically in order to perform optimally. This includes the changing of filters, checking of leakages, and proper heating and cooling mechanisms.
For instance, in a hospital, the HVAC system helps operate theatres since sterile environments are to be maintained in the theatres. Proper regular maintenance ensures standards are met concerning air quality and minimizes the chances of infection.
Heat, Flame and Smoke Detectors
The heat, flame, and smoke detectors are some of the key fire safety systems. These early detection devices in case potential fire hazards do arise thus calling for prompt responses for possible evaporation.
Mechanism
Modern fire detection systems utilize various technologies for the detection of smoke and heat, which include ionization and photoelectric sensors. The systems should be strategically located within a facility to accomplish appropriate coverage.
Example: An office building may install smoke detectors in hallways and common areas. Such detectors would activate alarms intended to warn occupants and emergency services in the case of fire.
Personnel Safety, Training, and Awareness
Safeguarding the personnel is a system defense priority. Organizations should plan training and provide resources necessary for training staff with respect to the various safety protocols, emergency procedures, and the need to maintain a safe environment.
Mechanism
Regular training and drills may be used in reinforcing the various safety protocols so that employees would be ready to deal effectively with emergencies. Awareness programs can also support a culture of safety within the organization.
Example: A manufacturing plant may have regular fire drills and safety training sessions so that employees would know how to act if there actually was a fire, or other type of emergency.
ABCD Fires and Suppression
Knowing the classes of fire is essential to effective fire safety management. The ABCD system categorizes fires by the type of material involved in the fire:
- Class A: Ordinary combustibles -wood, paper, cloth
- Class B: Flammable liquids – gasoline, oil, grease
- Class C: Electrical fires, wiring, appliances
- Class D: Combustible metals, magnesium, and titanium
How it works
Each fire classification requires a different type of fire suppression agent. Understanding these classifications helps the organization select the proper fire extinguishers and suppression systems to have on hand.
Example: A laboratory working with flammable chemicals might need Class B fire extinguishers, while a manufacturing facility working with metals could require Class D extinguishers in case of metal fires.
Types of Fire Suppression Agent
Fire suppression agents are substances used to extinguish or control fires. The type of agent used depends upon the class of fire and the environment where the agent will be applied.
Mechanism
Following are some of the more common fire suppression agents:
- Water: Class A fires; water should not be used on Class B or C fires.
- Foam: Smother Class B fires to prevent re-ignition.
- Dry Chemical: Class A, B and C fires use these agents.
- Carbon Dioxide (CO2): Effective on Class B and C fires; works by displacing oxygen to smother the fire.
- Clean Agents: Non-toxic agents that are used in sensitive environments, like data centers of organizations.
Example: The server room of an organization has a clean agent fire suppression system because the fire needs to be extinguished without destroying electronic equipment.
Conclusion
Strong system defenses and strong environmental controls are the two major ways to protect an organization’s assets, people, and information. Organizational safety and efficiency in the operating environment are thus achieved through asset tracking, port control, and environmental controls such as electricity management, HVAC, fire detection, and suppression strategies.
Periodically conducted training and awareness programs raise this bar of safety and preparedness higher by making personnel competent to handle all types of perceived risks.
In other words, maintenance and upgrades of the same would keep pace with evolving challenges in security, thus becoming an essential part of an organization’s integrated security strategy.
