What are four policy types supported by VMware Tanzu Mission Control?

Four policy types that are supported by VMware Tanzu Mission Control are:

Security policy: Security policies allow you to manage the security context in which deployed pods operate in your clusters by imposing constraints on your clusters that define what pods can do and which resources they have access to6.

Access policy: Access policies allow you to use predefined roles to specify which identities (individuals and groups) have what level of access to a given resource7.

Network policy: Network policies allow you to use preconfigured templates to define how pods communicate with each other and other network endpoints8.

Custom policy: Custom policies allow you to implement additional business rules, using templates that you define, to enforce policies that are not already addressed using the other built-in policy types9.
