What is the purpose of the FortiGuard Labs signature database?

The purpose of the FortiGuard Labs signature database is to keep FortiGate firewalls protected against the latest malware variants. This database is a crucial resource, as it provides up-to-date threat intelligence and signatures that help identify and block new and emerging threats. By continuously updating the signature database, FortiGuard Labs ensures that the FortiGate firewalls can defend against the most current forms of malware and cyber threats, thereby maintaining strong security posture for users.

The other options focus on different aspects that are not the primary function of the signature database. For instance, distributing online training is not related to the database, nor does it offer direct user support for firewall configurations. Similarly, enhancing performance is not the main goal, as the principal aim of the signature database is focused on security rather than performance optimization.
