What is Ephemeral Port Randomization?
In this glossary, Ephemeral Port Randomization refers to: A technique where ephemeral (temporary) TCP/UDP ports are assigned randomly to reduce the risk of port prediction attacks, as defined in IETF RFC 6056 and NIST SP 800-77.
How is Ephemeral Port Randomization used in cybersecurity?
In cybersecurity communication, this term appears in contexts such as: "Enable ephemeral port randomization on all client devices to prevent attackers from predicting port numbers and launching targeted exploits."
Why does Ephemeral Port Randomization matter in cybersecurity?
Ephemeral Port Randomization matters because it supports clear communication in Network Security contexts for SOC Analysts, Security Engineers, and Incident Responders. It also connects to aviation training and exam language such as CISSP, CompTIA Security+, and CEH.
Who uses Ephemeral Port Randomization?
Ephemeral Port Randomization is mainly used by SOC Analysts, Security Engineers, and Incident Responders.
What category does Ephemeral Port Randomization belong to?
In this glossary, Ephemeral Port Randomization is grouped under Network Security. Related pages in this category explain adjacent procedures, commands and operational concepts.
Where does this definition come from?
This definition is sourced from ISO 27001, NIST Cybersecurity Framework, MITRE ATT&CK and published by Protermify Cybersecurity as a static cybersecurity reference page.
