Which of the following is NOT one of the Eight Security Fundamentals for Privileged Account Security?

Using software firewalls is not listed as one of the Eight Security Fundamentals for Privileged Account Security. The Eight Security Fundamentals primarily focus on strategies and practices that ensure the secure management of privileged accounts, safeguarding sensitive information, and minimizing risks associated with privileged access.

Isolating and hardening the digital vault server is a crucial step in protecting the core repository of privileged accounts, while limiting permissions and points of administration plays a significant role in reducing the attack surface and ensuring that only authorized personnel have access. Protecting sensitive accounts and encryption keys is essential for maintaining the confidentiality and integrity of critical information.

In contrast, while software firewalls are important in a broader cybersecurity framework, they do not specifically address the fundamental principles associated with the management of privileged accounts as outlined within the context of the Eight Security Fundamentals. This distinction is what makes the use of software firewalls the correct choice in this scenario.
