What Each Port does Flashcards
SSH/SFTP
Secure Shell (SSH) is a software package that allows users to securely access and manage remote systems over an unsecured network.
SFTP, or Secure File Transfer Protocol, is a network protocol that securely transfers files over the internet
MySQL
MySQL is a relational database management system (RDBMS) developed by Oracle that is based on structured query language (SQL).
DNS
DNS, or the Domain Name System, translates human readable domain names (for example, www.amazon.com) to machine readable IP addresses (for example, 192.0. 2.44).
SMTP
SMTP stands for Simple Mail Transfer Protocol, and it’s an internet standard for sending and receiving email messages
FTP
FTP stands for File Transfer Protocol, a standard network protocol that allows users to transfer files between computers over the internet
TFTP
Trivial File Transfer Protocol (TFTP) is a simple protocol for transferring files between computers and servers. It’s often used to boot diskless workstations, routers, and X-terminals from a local area network.
Telnet
Telnet, or Teletype Network Protocol, is a client-server application that allows users to remotely access a computer’s virtual terminal
DHCP
Dynamic Host Configuration Protocol (DHCP) is a network management protocol that automatically assigns IP addresses and other network information to devices on a network
HTTP
Hypertext Transfer Protocol (HTTP) is a set of rules that govern how web browsers and servers communicate with each other to load web pages
HTTPS
HTTPS, or Hypertext Transfer Protocol Secure, is a secure version of HTTP that encrypts communication between a web browser and a website. HTTPS is used to protect sensitive information, such as cookies, user agent details, and form submissions, from being read or changed while in transit.
SMB
SMB stands for Server Message Block, a network protocol that allows users to share files, printers, and other resources between devices on a network. SMB is a client-server protocol, where clients request services and servers respond.
RDP
Remote Desktop Protocol (RDP) is a Microsoft-developed network communication protocol that allows users to remotely access and control computers.
SNMP
Simple Network Management Protocol (SNMP) is a widely used protocol for monitoring and managing devices on IP networks
POP3
POP3 (Post Office Protocol version 3) is an internet standard protocol that allows email clients to retrieve emails from a mail server
POP3 Secure
The secure port for POP3 (Post Office Protocol 3) is port 995, while the default, non-encrypted port is port 110
The encrypted port for POP3 that uses TLS/SSL. Port 995 is the standard port for SSL-encrypted POP3 communication.
Secure ports, like port 995, use SSL/TLS encryption to keep communications between your email client and server encrypted and safe from unauthorized access. Unencrypted connections expose your data to potential attackers, including your username, password, and all content of emails.
