Glossary
Ephemeral ports
In most cases, source ports are ephemeral, meaning random within a specified range. When an outgoing
request is made, the application solicits the host device for a port from its ephemeral pool. In a few cases,
the destination port is also ephemeral, meaning that both the source and destination ports are random.
IMAP
Internet Message Access Protocol—A protocol for retrieving e-mail messages.
SIP
Session Initiation Protocol—A signalling protocol used for establishing sessions in an IP network.
SSH
Secure Shell—A network protocol that allows exchange of data using a secure channel between two networked
devices.
