Managed Firewalls: How do They Work?
Firewalls have the options to block, allow, and restrict access to ports on the servers that are behind the firewalls. Whether they be physical servers, appliances of some type, or cloud servers, any of these can be protected by a firewall’s policies. You can allow a list of predetermined IP addresses to access a particular port, allow all IP address to access a particular port, or use a VPN connection through the firewall to access your network. Basically, a firewall is a gatekeeper that guards the ports on your server(s) from unauthorized access.
Note that firewalls are not proactive in the sense that they, for example, can monitor failed logins and then block an IP that has failed a certain number of logins. They are not connected to your server in the sense that they monitor logs, and so forth. However, they will protect you from common attacks such as port scans, large numbers of sessions from a single IP address, common network attacks, and other related attacks. With Gravity Servers’ Managed Firewall, we configure all of this for you, monitor it, and adjust any rules, and/or settings, as needed.
When you purchase a managed firewall, the firewall that you receive is dedicated to your environment specifically, and dedicated for your use. This is different than a shared firewall that some companies offer because it allows the firewall to handle a higher load if you need to push a large amount of data, or come under specific network attack. The firewall guards your server against any unauthorized access, based on your specific requirements.
Your firewall can also be divided into “Zones” with different rules, to make managing them an easier task. For example, you may have a “Web” zone, where your web servers go that have specific policies to allow HTTP and HTTPS traffic through, and nothing else. You could also have a “DB” zone, where your database servers reside, with the only traffic allowed to them coming from your servers, and the only way to access them from the outside being a VPN connection through the firewall. This completely protects and segregates them from the outside Internet, creating a safe zone that cannot even be reached by unauthorized individuals. Finally, you might have a “DMZ” zone, where there are absolutely no restrictive rules whatsoever, where servers are zoned that do not require any firewall protection at all.
Firewall zones can be as simple, or as complex as you like, and we will manage it all for you. It can even be as simple as there only being two zones: Untrust, where the Internet is, and Trust, which is where all of your servers reside. Regardless of how simple or complex the firewall setup, Gravity Servers is there every step of the way for you.
