Join Mike Chapple for an in-depth discussion in this video Host-based network security controls, part of CompTIA Security+ (SY0-501) Cert Prep: 2 Technologies and Tools.
- [Man] Firewalls are an important security control.…They act as the security guards of the network…monitoring attempts to start communications…and only allowing those connections…that match the enterprise security policy.…Firewalls follow the default deny principle…that says that any network connection…that is not exclusively allowed…should be blocked.…Connections to a computer should only be made…when the administrator determines…that the connection is necessary…to meet business requirements.…
Firewalls come in two forms.…Network firewalls are hardware devices…that sit in between two networks…and control the connections between those networks.…For example, organizations place network firewalls…at the borders of their networks…in between that organization's network…and the internet.…This network firewall forms an important part…of the organization's perimeter defense.…The network firewall only restricts those connections…that pass through the firewall.…
Connections between systems on the same network…are not restricted by the network firewall…
