Designing a DMZ

A DMZ greatly increases the security of a network. Any network with a web server and even one other machine can benefit from a DMZ. A DMZ is not only useful for a system that contains valuable or private information. Any one that wants to add an extra layer of protection to a machine can benefit from a DMZ. A DMZ, if properly configured, can quickly increase the security of any network. This is because there are twice as many machines for an attacker to compromise to get to anything valuable. This greatly increases the skill required of an external hacker to compromise the internal network and thus lowers the threat of the internal network being compromised. Of course, the defense-in-depth principle must be remembered and practiced, but a DMZ does provide a significant increase in security.
