What is a DMZ? (Demilitarized Zone)
PowerCert Animated Videos・2 minutes read
A DMZ enhances network security by isolating devices on different sides of a firewall, with servers like web and email servers placed in a perimeter network to allow public access without risking sensitive data. Two firewalls are recommended for a more secure DMZ setup, with the second firewall adding an extra layer of protection against potential security threats.
Insights
- By implementing a DMZ, organizations can safeguard sensitive internal data by placing public-facing servers outside the internal network, ensuring public access while maintaining security.
- The use of two firewalls in a DMZ setup significantly enhances network security by adding an extra layer of protection, making it more difficult for cyber threats to breach the company's internal network.
