Protocols like HTTP, DNS, and SSH define how data is exchanged over these ports. Common Ports We Will Discuss: SSH (22): Used for secure remote login and command execution. HTTP (80): The foundation of web traffic, transmitting data in plain text. HTTPS (443): Secure web traffic using encryption to protect data. DNS (53): Resolves domain names into IP addresses for communication. FTP (21): Transfers files between systems, often in plain text unless secured. Port scanning tools like nmap help ethical hackers identify open ports and potential vulnerabilities. Misconfigured services, like an SSH server with weak credentials, are prime targets for brute-force attacks. Outdated software on ports can lead to exploits like Remote Code Execution or vulnerabilities like EternalBlue. Unusual open ports can reveal hidden services, such as admin panels running on non-standard ports like 8080. Open ports and banners can expose critical information about the system and its software versions. Securing systems involves closing unnecessary ports, using firewalls, and running regular scans. Check out IPFire for an ethical hacker's dream firewall, or PortMaster to enhance the privacy of your Windows device. Understanding ports and protocols is essential for ethical hackers to identify and mitigate vulnerabilities. Make sure you learn them well. #EthicalHacking #CyberSecurity #NetworkingForHackers #LearnEthicalHacking #EthicalHackingBasics #NetworkingCourse #PenetrationTesting #HackingForBeginners
