Which of the following is an example of a process in a comprehensive security strategy?

Regular employee training sessions play a critical role in a comprehensive security strategy because they involve an ongoing process aimed at enhancing the security awareness and skills of employees. This training helps ensure that staff are informed about security policies, procedures, and best practices, which is essential for mitigating human-related security risks.

In contrast, advanced firewall technologies, upgrading software applications, and purchasing security systems represent more static components or discrete actions within a security strategy. While they are important for establishing a secure infrastructure, they do not embody the ongoing development and engagement that training sessions provide. Employee training is an interactive and continuous process that contributes to building a strong security culture within an organization, making it a vital aspect of a comprehensive security strategy.
