In what year did the Code of Conduct come into effect?

The correct answer is rooted in the historical timeline of the implementation of the Code of Conduct, which is a key document guiding the ethics and professional behavior expected of those working in security roles. The Code of Conduct came into effect in 2007, marking a significant step towards establishing clear guidelines and standards for the conduct of security personnel. This framework helps ensure accountability, professionalism, and ethical behavior within the security industry, aligning with best practices and legal requirements.

The years prior to 2007, such as 2005 and 2010, do not represent the onset of this crucial code, thus clarifying that while there may have been discussions or drafts, the formal implementation occurred in 2007. Meanwhile, 2012 falls well after the Code's introduction, which would not make sense in the context of its establishment. Understanding this timeline highlights the significance of the Code of Conduct in shaping the regulatory landscape for security professionals.
