Dual-Technology Sensors: These are security devices that utilize two different detection methods to increase accuracy and reduce the likelihood of false alarms. By requiring both detection methods to trigger before raising an alarm, the system can more accurately discern real threats from environmental factors or equipment malfunction.

Due Care: In the context of cybersecurity and business, due care refers to the level of judgment, attention, and prudence reasonably expected of a person in a particular position when taking actions to protect the interests of an organization and mitigate risks. It is essentially taking reasonable steps to protect a company and its assets from harm, which includes implementing and maintaining a comprehensive security program, regularly updating systems, and following best practices and compliance standards. Failure to exercise due care can lead to liability issues for an organization.

Due Diligence: In cybersecurity, due diligence refers to the careful investigation and evaluation of an organization's information security posture and practices. It involves assessing the effectiveness of security policies, procedures, and controls to identify risks, vulnerabilities, and threats to the organization's digital assets. This process is crucial when entering into business agreements or transactions to ensure that potential partners maintain adequate cybersecurity measures and comply with relevant regulations. Due diligence in cybersecurity aims to prevent data breaches, maintain privacy, protect intellectual property, and ensure business continuity.

Due Process: The legal requirement that an entity, especially a government, must respect all legal rights owed to a person, ensuring fairness and justice. This principle applies in a cybersecurity context when an entity, such as a corporation or an individual, is suspected of conducting illegal activities like hacking or other malicious activities.

Dumpster Diving: A practice where individuals sift through trash (physical or digital) in an attempt to uncover valuable information that could be used for unscrupulous purposes. While traditionally associated with searching through physical refuse for discarded documents, in a more modern sense, it can also refer to searching through discarded digital data.

Duress: A condition in which a person performs an act as a result of violence, threat, or other pressure against the individual. In the legal context, duress can make a contract voidable if one party involuntarily agrees due to the wrongful threat of the other party. In security terms, a duress code is a covert signal used by an individual to indicate they are in danger without alerting the potential aggressor, commonly used in security systems and protocols where silent alarms or emergency signals are necessary.
