Question

You need to manage a remote server. Which ports should you open on the firewall between your system and the remote server?

Answer 1

To manage a remote server, open TCP port 3389 for RDP, TCP port 22 for SSH, TCP port 21 for FTP, and TCP ports 80 and 443 for HTTP and HTTPS respectively.

Step-by-step explanation:

To manage a remote server, specific ports must be opened on the firewall to allow for various management protocols and tasks. For remote desktop access on Windows servers, you would typically open TCP port 3389, which is the default port for Remote Desktop Protocol (RDP). For secure shell access (SSH), which is commonly used on Linux servers, you need to open TCP port 22. If you need to transfer files, you may need FTP (TCP port 21) or SFTP (part of SSH on TCP port 22). For web server management, HTTP (TCP port 80) and HTTPS (TCP port 443) might be necessary. It's crucial to ensure only necessary ports are open and to consider implementing additional security measures such as IP whitelisting, VPN access, or using authentication keys for SSH.
