"Unlocking Digital Doors: A Comprehensive Guide to Enumerating Open Ports - HTTP/S, SMB, SNMP, SMTP in Cybersecurity"

Enumerating Open Ports - HTTP/S, SMB, SNMP, SMTP:
Enumeration is a crucial phase in cybersecurity, particularly during ethical hacking and penetration testing. It involves extracting detailed information about the services running on identified open ports. Here, we'll delve into the enumeration of specific open ports such as HTTP/S (web services), SMB (Server Message Block), SNMP (Simple Network Management Protocol), and SMTP (Simple Mail Transfer Protocol).
Enumeration of Open Ports:

1. HTTP/S (Ports 80 and 443):
   
   • Purpose: Used for web services.
   • Enumeration Steps: Identifying web server software, determining the web server's version, and discovering web applications and directories.
2. SMB (Ports 137-139, 445):
   
   • Purpose: Used for file and printer sharing.
   • Enumeration Steps: Identifying the SMB version, discovering shares and permissions, and extracting information about users and groups.
3. SNMP (Port 161):
   
   • Purpose: Used for network management.
   • Enumeration Steps: Extracting information about devices, systems, and network topology, including community string guessing to gain access.
4. SMTP (Port 25):
   
   • Purpose: Used for email transmission.
   • Enumeration Steps: Identifying the mail server, extracting information about email addresses, discovering mail relay configurations, and determining email server software.
