The most relevant source to reference when updating security awareness training materials is the recent security incidents reported by competitors. This can help to illustrate the real-world threats and consequences of poor security practices, and to motivate the employees to follow the security policies and procedures. Risk management framework, risk register, and global security standards are other sources that may be useful, but they are not as relevant as the recent security incidents. References = ISACA Certified in Risk and Information Systems Control (CRISC) Certification Exam Question and Answers, question 9; CRISC Review Manual, 6th Edition, page 214.
