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.
