 Explanation:

By analyzing the IT infrastructure and ensuring security solutions adhere to the principles of how hardware and software are implemented and managed, the CISO demonstrates effective use of existing technologies.

This principle focuses on leveraging and optimizing current IT assets to maximize value and efficiency.

 Why Other Options Are Less Relevant:

A. Alignment with the business: This relates to ensuring security goals align with organizational objectives but is broader than analyzing infrastructure.

C. Leveraging existing implementations: While related, this does not explicitly address management and implementation of hardware/software.

D. Proper budget management: Budget management focuses on financial aspects, not technical alignment.

 EC-Council CISO Reference:Emphasizes the importance of maximizing existing technology investments as part of an efficient and secure IT strategy.
