As shown in the figure below, you can see red colour in the Encryption key for New and Updated records.  By default, Default key  is displayed. This should be changed to Secure Storage filesystem for NW 740 and higher.

This is done by using Key Management on tab. Note that do not use Manage wizard.

What is Secure Storage Filesystem and what are the applications that uses secure storage filesystems that stored password in the secure storage filesystem.

This is described in the link http://help.sap.com/saphelp_nw70ehp2/helpdata/en/a0/82dd0abbde4696b98a8be133b27f3b/content.htm

only ABAP applications are supported in SSFS. Java does not support SSFS implementataion. Hence this document is only suitable for ABAP applications.

You will find two files pertaining to SSFS viz : SSFS_<SID>.DAT which contains database user for SAP objects i.e. SAP Schema user like SAPSR3 and its associated password. As of NW 740, OPS$ mechanism is no longer supported. Instead  SAP work processes read the content of SSFS_<SID>.DAT  – the entry for SAP Schema user id and its password. However there was no data encryption in these two files.
