Network-based firewall[edit]

Network based firewalls – monitor traffic on the entire network segment, meaning an administrator monitors and controls firewall services from a central location.

Hardware firewall

Host based firewalls – is installed on an individual system and monitors and controls inbound and outbound traffic for just that system.

Software firewall

IDS (Intrusion Detection System)[edit]

IPS (Intrusion Prevention System)[edit]

VPN (Virtual Private Network) concentrator[edit]

VPN concentrators increase remote access security. Concentrators sit between the VPN client and VPN server, creating a tunnel authenticating users and encrypting data as it travels. They also regulate and monitor data transfer across the tunnel, and control inbound and outbound traffic as an endpoint or router.
