The best reason to conduct a social engineering test in a call center is to identify candidates for additional security training because it helps to assess the level of awareness and skills of the call center staff in recognizing and resisting social engineering attacks, and provide them with the necessary training or education to improve their security posture. Minimizing the likelihood of successful attacks is not a reason to conduct a social engineering test, but rather a possible outcome or benefit of conducting such a test. Gaining funding for information security initiatives is not a reason to conduct a social engineering test, but rather a possible outcome or benefit of conducting such a test. Improving password policy is not a reason to conduct a social engineering test, but rather a possible outcome or benefit of conducting such a test.

Information security governance is the process of establishing and maintaining a framework to provide assurance that information security strategies are aligned with business objectives and consistent with applicable laws and regulations. In addition to executive sponsorship and business alignment, a critical factor for effective information security governance is ownership of security, which means that the roles and responsibilities for information security are clearly defined and assigned to the appropriate stakeholders, such as business owners, information owners, information custodians, and users. Ownership of security also implies accountability for the protection of information assets and the management of security risks.
