Blocked Port Definition: A blocked port refers to a network port that has been closed off to prevent unauthorized access or communication.
A blocked port in cybersecurity refers to a network port that has been intentionally restricted or disabled to prevent communication through that specific network pathway. This action is often taken to enhance security by restricting unauthorized access to vulnerable services or systems that could be exposed through open network ports. Blocking ports can be accomplished through firewall configurations, network access control mechanisms, or security policies to safeguard against potential cyber threats.
