Firewall Rules
Sonoran Shield allows you to easily lock down unused ports, restrict access based on IPs, and more!
Open and unused ports represent potential security vulnerabilities. Attackers can exploit open ports to gain unauthorized access to a system, take down your server through denial of service attacks (DoS/DDoS) and compromise its security. By blocking unused ports, organizations can reduce their attack surface and minimize the risk of a successful attack. It is a best practice to only allow traffic on necessary ports to limit potential vulnerabilities and maintain the security of the system.
Sensitive ports can be limited to only authorized source IP addresses (your developers for example) to limit attack surface further while allowing access to authorized users.
Getting Started with Firewall Rules
1. Block all Unused Ports
The first rule will block access on all unused ports. After this, we will add rules to open only the ports we need.
Select
New Rule
Add your server's IP address in the
Destination
drop-downSelect
Network
as theSource Type
Set the
Source IP
to0.0.0.0/0
Leave the
Protocol
,Source Port
, andDestination Port
fields blankSet the
Action
toBlock
Save the new rule
2. Add a port for RDP
Next, we will want to open up a port for remote desktop connections. This will allow us to use Window's RDP to view/manage our server.
Select
New Rule
Add your server's IP address in the
Destination
drop-downSelect
Network
as theSource Type
Set the
Source IP
to:Allow any IP:
0.0.0.0/0
Or, allow only your specific IP address to connect
Set
Protocol
toTCP
Leave the
Source Port
field blankSet the
Destination Port
to 3389This is the default RDP port for Windows servers
Set the
Action
toAllow
Save the new rule
Continue this process to open additional ports for your game server and any other applications.
