6 Disable the Telnet Service

The Oracle Argus Mart application does not use the Telnet service. Telnet listens on port 23 by default. If the Telnet service is available on the Oracle Argus Mart host machine, Oracle recommends that you disable Telnet in favor of Secure Shell (ssh). Telnet, which sends clear-text passwords and user names through a login, is a security risk to your servers. Disabling Telnet tightens and protects your system security.
