VMware vShield is a suite of security virtual appliances built for VMware vCenter Server and VMware ESX integration. vShield is a critical security component for protecting virtualized datacenters from attacks and misuse helping you achieve your compliance-mandated goals. vShield App is an interior, vNIC-level firewall that allows you to create access control policies regardless of network topology. A vShield App monitors all traffic in and out of an ESX host, including between virtual machines in the same port group. vShield App includes traffic analysis and container-based policy creation. In this video I'll show you that vShield App installs as a hypervisor module and firewall service virtual appliance. vShield App integrates with ESX hosts through VMsafe APIs and works with VMware vSphere platform features such as DRS, vMotion, DPM, and maintenance mode. vShield App provides firewalling between virtual machines by placing a firewall filter on every virtual network adapter. The firewall filter operates transparently and does not require network changes or modification of IP addresses to create security zones. You can write access rules by using vCenter containers, like datacenters, cluster, resource pools and vApps, or network objects, like Port Groups and VLANs, to reduce the number of firewall rules and make the rules easier to track. You should install vShield App instances on all ESX hosts within a cluster so that VMware vMotion operations work and virtual machines remain protected as they migrate between ESX hosts. By default, a vShield App virtual appliance cannot be moved by using vMotion. The Flow Monitoring feature displays allowed and blocked network flows at the application protocol level. You can use this information to audit network traffic and troubleshoot operational.
