wolfSentry: A turnkey dynamic firewall for lwIP
wolfSentry, wolfSSL’s embedded firewall and IDPS, now supports out-of-the-box integration with lwIP! After simple initialization calls at application startup, all network traffic is evaluated and subject to filtration by the wolfSentry engine. Prefiltering by network layer, protocol, and event type, allows zero-overhead transparency for selected traffic. For example, TCP connection requests, inbound and/or outbound, can […]
