Which of the following describes network traffic that originates from the inside of a network perimeter and progresses towards the outside?

Ingress traffic is the opposite direction - it enters the network from an external source toward internal hosts, such as inbound internet traffic hitting a firewall.

'Inwards network' is not a recognized or standardized networking term and does not appear in formal protocol or security documentation.

In networking, egress refers to traffic exiting a defined network boundary - packets generated by internal hosts destined for external networks. Egress filtering is a standard security control applied at the perimeter to detect data exfiltration and enforce outbound policy, making this the precise technical term for inside-to-outside traffic flow.

'Outwards network' is not a standard networking term used in any formal protocol specification or security framework to classify traffic direction.
