If you’re thinking about using a demilitarized zone (DMZ) to protect against cyber threats, you might be wondering which services to place in it. Many businesses use a DMZ to protect some of their services from cyber threats. It acts as a perimeter network.
The DMZ will sit between the business’s local area network (LAN) and a public network, such as the internet. Untrusted traffic must pass through the DMZ to reach the business’s LAN. If you use a DMZ, you can set it up with a firewall and other cybersecurity tools. The DMZ’s firewall and cybersecurity tools will protect the included service or services from cyber threats. What type of services can you place in a DMZ exactly?
Some businesses use a DMZ for File Transfer Protocol (FTP) services. FTP is a protocol that facilitates the exchange of files between two devices. You can use an FTP client to download files from a remote server to your local computer, or you can use an FTP client to upload files from your local computer to a remote server.
FTP services such as this, however, come with an inherent risk of a breach. A hacker may use an FTP service to access your business’s server. By placing FTP services in a DMZ, you can lower the risk of FTP-related breaches such as this.
Voice over Internet Protocol (VoIP) services are commonly placed in DMZs. Not to be confused with Wi-Fi calling, VoIP is a type of voice communications technology that allows for the delivery of voice data over the internet. Statistics shows that up to 31% of all businesses use VOIP.
If your business uses a VOIP service, you should consider placing it in a DMZ. VOIP services require a connect between your business’s LAN and the internet. The internet is a public network, and like most public networks, you can’t always trust its traffic. Placing the VOIP service in a DMZ will keep your business’s LAN safe from cyber threats.
#3) Web Servers
You can place web servers in a DMZ. Businesses often use web servers to host websites and apps.
Rather than placing a web server on your business’s LAN, you can place it in a DMZ. The DMZ will isolate the web server so that it’s virtually separated from your business’s LAN. Users will still be able to access the web server from the internet, but the DMZ will hinder their ability to access your business’s LAN. Along with FTP and VOIP, web servers are often placed in DMZs for cybersecurity purposes.
