RDPGuard for Windows is a security application designed to enhance the security of Remote Desktop Protocol (RDP) connections. It primarily works by adding an extra layer of protection against brute-force attacks and unauthorized access attempts. Instead of relying solely on the built-in Windows security measures, RDPGuard adds features like :

*

IP address blocking:

It allows you to specify allowed IP addresses, blocking all others from connecting via RDP. This is a crucial preventative measure against bots and attackers scanning for open RDP ports.

*

Account lockout:

It can implement more aggressive account lockout policies than Windows[SQ] default settings, further deterring brute-force attempts.

*

Connection logging:

It logs all RDP connection attempts, successful or unsuccessful, providing valuable auditing information for security analysis. This can help identify suspicious activity.

*

Two-factor authentication (2FA) integration (in some versions):

Some advanced versions might integrate with 2FA systems, requiring a second verification step for login, dramatically increasing security.

*

Port changing:

While not always a feature, some RDPGuard implementations allow for changing the default RDP port (3389), making it harder for attackers to find and exploit the service.


In short, RDPGuard acts as a security gatekeeper for your RDP connections, making it significantly more difficult for unauthorized users to gain access to your Windows system. However, it[SQ]s crucial to note that it[SQ]s *not* a replacement for strong passwords, regular software updates, and other good security practices. It[SQ]s an *addition* to a broader security strategy.
