What method can be used to estimate the likelihood of a bomb attack?

Estimating the likelihood of a bomb attack requires a comprehensive understanding of the environment in which an organization operates. Assessing the organization's changing profile is crucial for identifying potential threats. This involves analyzing factors such as changes in operations, employee demographics, the nature of goods or services provided, and any recent incidents or alerts that could heighten risk levels. As organizations evolve, so too do the risks they face, making it essential to stay updated on these changes.

By understanding the organization's profile, security professionals can better identify vulnerabilities and threats that may emerge as a result of these transformations. This proactive approach can inform security measures and resource allocation, helping to mitigate potential risks associated with bomb attacks. In contrast, the other options do not directly contribute to estimating the likelihood of a bomb attack in a meaningful way. Conducting social media audits may provide insights into public perceptions but does not directly assess potential threats. Increasing advertising spending and hiring additional staff do not inherently impact threat assessment or likelihood estimates.
