Finding ID	Version	Rule ID	IA Controls	Severity
V-26740	SRG-NET-000020	SV-33988r1_rule		Medium

Description
Information flow control regulates where information is allowed to travel within a network and between interconnected networks. The flow of all network traffic must be monitored and controlled so it does not introduce any unacceptable risk to the network infrastructure or data. Restrictions can be enforced based on source and destination IP addresses as well as the ports and services being requested. This requirement should enforce the deny-by-default policy whereby only the known and accepted traffic will be allowed outbound and inbound.
