What security technique could provide secure access to a server located in a small office without the expense of implementing a DMZ or purchasing a hardware firewall?
- implement hash encoding for all wireless devices
- implement MAC address filtering
- implement port forwarding
- implement basic security on all wireless access points
Explanation: Port forwarding provides a rule-based method to direct traffic between devices on separate networks. This method provides access to devices across the Internet in a less expensive way than using a DMZ.
