# azure\_security\_group\_rule
Creates a new network security rule to be associated with a given security group.
Creates a new network Security Group Rule to be associated with a number of
given Security Groups.
~> **NOTE on Security Group Rules**: for usability purposes; Terraform allows the
addition of a single Security Group Rule to multiple Security Groups, despite
it having to define each rule individually per Security Group on Azure. As a
result; in the event that one of the Rules on one of the Groups is modified by
external factors, Terraform cannot reason as to whether or not that change
should be propagated to the others; let alone choose one changed Rule
configuration over another in case of a conflic. As such; `terraform refresh`
only checks that the rule is still defined for each of the specified
`security_group_names`; ignoring the actual parameters of the Rule and **not**
updating the state with regards to them.
## Example Usage
