What are the potential security risks of having open ports?

Having open ports increases the attack surface of your server, making it vulnerable to various security threats. Hackers can exploit open ports to gain unauthorized access to your system, steal data, or launch attacks. Common vulnerabilities associated with open ports include SQL injection, cross-site scripting (XSS), and remote code execution. Cloudflare helps mitigate these risks, but it's important to understand the potential dangers.
