143
IMAP (Internet Message Access Protocol)
is an Internet standard protocol used by email clients to retrieve email messages from a mail server over a TCP/IP connection.
161
SNMP (Simple Network Message Protocol)
is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior.
162
SNMP traps
is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior.
SNMP traps enable an agent to notify the management station of significant events by way of an unsolicited SNMP message.
389
LDAP (Lightweight Data Acquisition Protocol)
is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network.
443
HTTPS Hypertext Transfer Protocol over TLS/SSL)
is an extension of the Hypertext Transfer Protocol (HTTP). It is used for secure communication over a computer network, and is widely used on the Internet. In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS) or, formerly, its predecessor, Secure Sockets Layer (SSL).
445
Microsoft Active Directory and Server Message Block
AD is a directory service developed by Microsoft for Windows domain networks. It is included in most Windows Server operating systems as a set of processes and services.
SMB is a network communication protocol for providing shared access to files, printers, and serial ports between nodes on a network. It also provides an authenticated inter-process communication mechanism.
500
