Introduction Firewall protects information and prevents systems, network resources, and applications from being compromised. Firewall acts as a filter between a computer and the network or the Internet. The firewall scans all incoming and outgoing traffic at the packet level. As it reviews each arriving or departing packet, the firewall checks its list of firewall rules, which is a set of criteria with associated actions. If a packet matches all criteria in a rule, the firewall acts according to the rule, blocking or allowing the packet through the firewall. Firewall is fully integrated with McAfee ePO and uses its framework to deliver and enforce policies. This approach provides a single management solution that allows for mass deployment of up to 100,000 systems in multiple languages across an entire enterprise. How firewall rules work Firewall rules determine how to handle network traffic. Each rule provides a set of conditions that traffic must meet and an action to allow or block traffic. How firewall rule groups work Use Firewall rule groups to organize firewall rules for easy management. Firewall rule groups don't affect the way Firewall handles the rules within them; Firewall still processes rules from top to bottom. Firewall stateful packet filtering and inspection Firewall provides both stateful packet filtering and stateful packet inspection. Tuning Firewall Tuning involves balancing intrusion prevention protection with access to required information and applications per group type. McAfee ePO features leveraged by Firewall Firewall leverages these features in the McAfee ePO environment.
