Discussion

Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port that has been left unattended. In addition, quickly terminating an idle session will also free up resources committed by the managed network element.

Check Content

Refer to the file specified on the SYSFTPD DD statement in the FTP started task JCL.

If the INACTIVE statement is coded with a value greater than "600", this is a finding.

If the INACTIVE statement is coded with a value of "0", this is a finding.

If there is no INACTIVE statement coded or the INACTIVE statement is commented out, this is a finding.

Fix Text

Code the FTPD configuration file to include the INACTIVE statement with a value between "1" and "600".
