TCP 2484

ProtocolTCP
Port2484
LabelsOracle database listening for SSL client connections to the listener

Synopsis

  • TCP port 2484 is commonly used by Oracle Database’s Oracle Net Services (TNS) for encrypted TCPS (SSL/TLS) connections, known as “Oracle TTC SSL.”
  • The Oracle Listener can be set to listen on 2484 for secure client access from tools like SQL*Plus, Oracle JDBC Thin driver (using tcps), and Oracle Net Manager.
  • Oracle applications such as Oracle Enterprise Manager, Oracle E-Business Suite, and Oracle GoldenGate often connect to Oracle Databases over TCPS via 2484 when secure transport is configured.
  • Managed offerings like Amazon RDS for Oracle and Oracle Cloud (including Autonomous Database) support or expose TCPS on 2484 for encrypted client connections.
  • Although 1521 is the usual default port for Oracle TNS, 2484 is the standard port specifically for TCPS.
  • Security note: This port is frequently probed because it indicates an Oracle TNS listener; attacks like the TNS Listener Poison vulnerability (CVE-2012-1675) and password/brute-force attempts can target services on 2484.
