[NS Wk 1] Practical - Firewall VM Initial Setup

Firewall Configuration Concepts

Commit

Allows users to review and validate configurations before applying them to the firewall. This is a best practice to avoid misconfigurations.

Ingress Filtering

Inspection and filtering of incoming traffic at network entry points. Mitigates risk of attacks like spoofing by ensuring incoming packets have a valid source IP address belonging to the network where the traffic originated.

Egress Filtering

Inspection and filtering of outgoing traffic from a network. Prevents data leakage or spoofing attacks by ensuring source IP address belongs to the internal network or valid IP address range, else it is dropped by the firewall.
