Abstract
Techniques are disclosed for redirecting network traffic of virtualized application workload to a host-based firewall. For example, a system comprises a software defined networking (SDN) controller of a multi-tenant virtualized data center configured to: receive a security policy expressed as one or more tags to redirect traffic of a virtualized application workload to a host-based firewall (HBF) of the multi-tenant virtualized data center; configure network connectivity to the HBF in accordance with the security policy; a security controller that manages the HBF configured to: obtain the one or more tags from the SDN controller; receive one or more firewall policies expressed in terms of the one or more tags, wherein each of the one or more firewall policies specifies a function of the HBF; and configure the function of the HBF in accordance with the one or more firewall policies.
