According to the documentation, resource protection detects and prevents session exhaustion attacks against specific destinations. This type of attack uses a large number of hosts to establish as many fully established sessions as possible to consume all of a system's resources. Resource protection defines the maximum number of concurrent connections for a destination IP address or zone. Reference: 1 Security Profile: DoS Protection Profile - Palo Alto Networks

URL filtering is a feature in Palo Alto Networks firewalls that allows administrators to block access to specific URLs [1]. This feature can be configured via four different objects: Custom URL categories in URL Filtering profiles, PAN-DB URL categories in URL Filtering profiles, External Dynamic Lists (EDL) in URL Filtering profiles, and Custom URL categories in Security policy rules. The evaluation order for URL filtering is: Custom URL categories in URL Filtering profile, PAN-DB URL categories in URL Filtering profile, EDL in URL Filtering profile, and Custom URL category in Security policy rule.
