Final answer:
The greatest threat to an organisation's security is often human sources, with employee mistakes and misinterpretations leading to significant breaches, such as the Target data breach. The increase in digital activity raises concerns around cybercrime and privacy, whilst broader national security concerns encompass economic, energy, and environmental aspects, alongside conventional military threats.
Step-by-step explanation:
The greatest threat to an organisation's security often comes from human sources. This encompasses both intentional and unintentional actions from inside the organization, such as employees or contractors, which can lead to security breaches. An example would be the case of Target's data breach in 2013, where there were indications that security personnel misinterpreted signals of a security breach. Studies, such as the one by Bruno & Abrahão (2012), have shown that the volume of decisions made by operators can lead to an increase in mistakes, particularly when identifying false security incidents under increased cognitive load. Additionally, online privacy, security, and the risk of cybercrimes are heightened as we increase our digital presence. Pew Research Center surveys have revealed a growing concern among citizens about the amount of personal information available online, and the potential harassment and identity theft that can occur.
Risks to security are not limited to individuals but also to national security, which has broadened to include economic, energy, and environmental security. The threat of cybercrime and cyberwarfare, privacy infringement, data misuse, the declining human skills due to technology reliance, and job loss due to AI and automation are common concerns among industry leaders, as noted by Pew Research Center reports.
