SF6-filled detection systems for bid

NIDS systems resemble firewalls in a lot of ways. But a firewall is designed to prevent intrusions by blocking potentially malicious traffic coming from outside, and enforce ACLs between networks. NIDS systems are meant to detect and alert on potential malicious activity coming from within the network.
