 Supplying a duress alarm for personnel exposed to the public is the most cost-effective method to provide a reactive control for protecting personnel in public areas. A duress alarm is a device that allows a person to signal for help in case of an emergency, such as an attack, a robbery, or a medical condition. A duress alarm can be activated by pressing a button, pulling a cord, or speaking a code word. A duress alarm can alert security personnel, law enforcement, or other responders to the location and nature of the emergency, and initiate appropriate actions. A duress alarm is a reactive control because it responds to an incident after it has occurred, rather than preventing it from happening.

The other options are not as cost-effective as supplying a duress alarm, as they involve more expensive or complex technologies or resources. Installing mantraps at the building entrances is a preventive control that restricts the access of unauthorized persons to the facility, but it also requires more space, maintenance, and supervision. Enclosing the personnel entry area with polycarbonate plastic is a preventive control that protects the personnel from physical attacks, but it also reduces the visibility and ventilation of the area. Hiring a guard to protect the public area is a deterrent control that discourages potential attackers, but it also involves paying wages, benefits, and training costs.

A Business Impact Analysis (BIA) is a process that identifies and evaluates the potential effects of natural and man-made disasters on business operations. The BIA questionnaire is a tool that collects information from business process owners and stakeholders about the criticality, dependencies, recovery objectives, and resources of their processes. The BIA questionnaire should include questions that:

• Identify the operational impacts of a business interruption, such as loss of revenue, customer satisfaction, reputation, legal obligations, etc.
• Identify the financial impacts of a business interruption, such as direct and indirect costs, fines, penalties, etc.
• Determine the technological dependence of the business processes, such as hardware, software, network, data, etc.
• Establish the recovery time objectives (RTO) and recovery point objectives (RPO) for each business process, which indicate the maximum acceptable downtime and data loss, respectively.

The BIA questionnaire should not include questions that determine the risk of a business interruption occurring, as this is part of the risk assessment process, which is a separate activity from the BIA. The risk assessment process identifies and analyzes the threats and vulnerabilities that could cause a business interruption, and estimates the likelihood and impact of such events. The risk assessment process also evaluates the existing controls and mitigation strategies, and recommends additional measures to reduce the risk to an acceptable level.

Purging or re-imaging the hard disk drive of a laptop before traveling to a high risk area will reduce the risk of data compromise or theft in case the laptop is lost, stolen, or seized by unauthorized parties. Purging or re-imaging the hard disk drive will erase all the data and applications on the laptop, leaving only the operating system and the essential software. This will minimize the exposure of sensitive or confidential information that could be accessed by malicious actors. Purging or re-imaging the hard disk drive should be done using secure methods that prevent data recovery, such as overwriting, degaussing, or physical destruction.

The other options will not reduce the risk to the laptop as effectively as purging or re-imaging the hard disk drive. Examining the device for physical tampering will only detect if the laptop has been compromised after the fact, but will not prevent it from happening. Implementing more stringent baseline configurations will improve the security settings and policies of the laptop, but will not protect the data if the laptop is bypassed or breached. Changing access codes will make it harder for unauthorized users to log in to the laptop, but will not prevent them from accessing the data if they use other methods, such as booting from a removable media or removing the hard disk drive.

The best description of the responsibilities of a data owner is determining the impact the information has on the mission of the organization. A data owner is a person or entity that has the authority and accountability for the creation, collection, processing, and disposal of a set of data. A data owner is also responsible for defining the purpose, value, and classification of the data, as well as the security requirements and controls for the data. A data owner should be able to determine the impact the information has on the mission of the organization, which means assessing the potential consequences of losing, compromising, or disclosing the data. The impact of the information on the mission of the organization is one of the main criteria for data classification, which helps to establish the appropriate level of protection and handling for the data.

The other options are not the best descriptions of the responsibilities of a data owner, but rather the responsibilities of other roles or functions related to data management. Ensuring quality and validation through periodic audits for ongoing data integrity is a responsibility of a data steward, who is a person or entity that oversees the quality, consistency, and usability of the data. Maintaining fundamental data availability, including data storage and archiving is a responsibility of a data custodian, who is a person or entity that implements and maintains the technical and physical security of the data. Ensuring accessibility to appropriate users, maintaining appropriate levels of data security is a responsibility of a data controller, who is a person or entity that determines the purposes and means of processing the data.
