________ firewalls may be able to stop attacks by employees within the firm against internal site resources.

• A. Internal
• B. External
• C. UTM
• D. Border

Answer: (A)

Insider threats require controls inside the network. An internal firewall sits within the organization, between internal segments or between user devices and internal resources, and enforces strict access rules for traffic moving inside. By segmenting the network and restricting who and what can talk to sensitive resources, it can block unauthorized access or lateral movement even if an employee has legitimate credentials. External or border firewalls guard against threats from outside the firm and aren’t focused on internal abuse, while UTMs are usually deployed at the perimeter to provide multiple security functions. The internal firewall approach directly targets traffic within the network to protect internal site resources.
