Firewalls, IDS, and IPS Explained - Network+ N10-009
Watch on YouTube Firewalls, IDS, and IPS are the three pillars of network security defense - but each one works differently and sits in a different spot on the network. This video breaks down packet filter vs stateful vs NGFW firewalls, ACL rule processing with implicit deny, IDS passive monitoring vs IPS inline blocking, and the difference between signature-based and anomaly-based detection including false positives and false negatives. We also cover forward proxies, reverse proxies, WAFs at Layer 7, and UTM appliances. Watch the next video: VPN Technologies - Site-to-Site, Remote Access, and IPsec vs SSL.
