What configuration adjustment can enhance access control in FortiGate?

Configuring stricter security policies enhances access control in FortiGate by allowing administrators to define precise rules that govern the traffic entering and leaving the network. Stricter policies can restrict access based on various parameters such as source and destination IP addresses, ports, applications, or user identities. This specificity minimizes the risk of unauthorized access, protects sensitive data, and ensures that only legitimate traffic is permitted based on the organization's security requirements.

For example, if a company only wants to allow specific applications or services, the administrator can create security policies that explicitly define these parameters. This approach not only helps in mitigating risks but also ensures compliance with regulatory requirements by enforcing the necessary controls on data and network usage. By concentrating on the smallest and most effective configurations, organizations can better manage and monitor their security landscape.

In contrast, increasing CPU performance may improve processing speed but does not directly impact the effectiveness of access control. Removing unused firewall rules can aid in management efficiency but does not inherently strengthen access policies. Disabling logging features can hinder the ability to track and audit traffic flows, which is critical for detecting potential security incidents, thus negatively impacting security posture.
