Is a basic home router firewall enough for SC.L1-b.1.x (Boundary Protection) in CMMC Level 1?

A basic router firewall can contribute to SC.L1-b.1.x, but its configuration is key. It should be set up to block unsolicited inbound connections and allow only necessary outbound traffic. For businesses, a dedicated business-grade firewall might offer more robust control and logging for FCI protection.
