What is the requirement for the frequency of security awareness training according to the guidelines?

The requirement for the frequency of security awareness training as outlined in most organizational guidelines is set at every two years. This interval helps ensure that personnel remain current with relevant security practices, emerging threats, and updated policies. By conducting training every two years, organizations can effectively refresh their employees' knowledge and reinforce the importance of security measures, reducing the risk of security breaches due to human error.

Training too frequently, such as annually, may lead to training fatigue or information overload, while longer intervals like every three to five years might result in employees being ill-prepared to address ongoing security challenges in a rapidly changing digital landscape. Thus, every two years is a balanced approach to maintaining security awareness and adapting to evolving risks.
