Set Maximum Number of Incoming Connections

SedangLevel 1Otomatissolaris

Deskripsi

This setting controls the maximum number of incoming connections that can be accepted on a TCP port. Note that the value of 1024 is a minimum to establish a good security posture for this setting. In environments where connection numbers are high, such as a busy webserver, this value may need to be increased. Audit: `ipadm show-prop -p _conn_req_max_q` must be 1024 for both the current and persistent values.
