SunFirewall

SunFirewall comes as an extra layer of protection for users that are remotely connecting to their systems and need to ensure that hackers or other ill-intended entities are not able to slip in and compromise your data.

This feature is an adaptation for the blacklist denomination and provides a wall between your port and any country you like. The default port (3389) renders your system vulnerable in case your credentials get compromised. You can change the port of course, but you can also blacklist the countries you suspect attacks might come from.

To make sure you reduce the number of threats, you can block all the countries and allow access to the ones that the client is using to connect from.

Brute Force is a hacking method of running all the combinations possible until one matches the credentials, and gets access to your system. This feature is automatic and detects the IPs that are trying multiple passwords in order to connect to your computer. The IPs are going to be listed in the preview panel along with important information about location, country, and time zone.

However, input mistakes can be made, so the application recommendation is to limit the login attempts to 3. However, you can set the number of attempts to any value. In case of accidental IP blocks, you can revert the action by clearing the IP from the list.

A user gains the status of “suspected” if the location used to connect to your computer changes after a short time. For example, if a user logs in from the United States and later connects from China, the algorithm will mark them as suspected.

SunFirewall is a neat tool that helps you secure your connection to a remote system. Its main features are the possibility to block access from specific countries and the automatic access denial for IPs that failed to provide the correct passwords while logging in. Recommended for users that employ the RDP protocol on a daily basis and need to make sure that no unwanted person can access their information.
