What is the primary function of security policies in Fortinet devices?

The primary function of security policies in Fortinet devices is to define allowed and disallowed traffic. Security policies are critical components of Fortinet's security architecture, as they set the rules that govern how data packets are handled by the network. Each policy specifies which types of traffic can pass through the device and under what conditions, thereby controlling access to resources and protecting the network from unauthorized access or attacks.

By implementing these policies, organizations can enforce security measures tailored to their specific needs, ensuring that only legitimate and approved communications occur while blocking potentially harmful traffic. This allows for precise control over the network landscape, which is essential for maintaining a secure and efficient environment.

While managing network traffic flow and enhancing device performance are important aspects of overall network management, they are not the primary focus of security policies. Firmware updates, on the other hand, are related to device maintenance rather than the enforcement of security measures.
