To help protect the internal network, an organization should:

 Protecting Internal Networks:

Unlicensed software can pose significant risks, including malware, data breaches, and legal liabilities. Preventing its installation ensures a secure network environment.

 Why Preventing Unlicensed Software is Correct:

This practice reduces vulnerabilities and ensures compliance with software licensing laws, safeguarding the network.

 Eliminating Incorrect Options:

A. Warn employees by sharing suspicious emails: While useful, it’s a reactive measure and less effective as a preventive strategy.

C. Reveal passwords only to supervisors and managers: Passwords should never be shared, regardless of rank.

D. Give all employees access to the organization’s firewall: This would compromise the firewall’s effectiveness.
