Explain the following methods of network security: - authentication
- encryption
- firewall
- MAC address filtering.
| Students should be able to explain, using examples, what each of these security methods is and when each could be used. Students should understand how these methods can work together to provide a greater level of security. The capabilities of firewalls have changed dramatically in recent years and will continue to do so. Students should be aware that a firewall is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules. Students should understand that MAC address filtering allows devices to access, or be blocked from accessing a network based on their physical address embedded within the device’s network adapter. |
