Gary McGraw, Brian Chess, and Sammy Migues interviewed nine executives running top software security programs, and wrote an article for InformIT. Some results showed that we are still not doing enough, even at our best. Some showed that some of the things we stress most heavily are actually wrong. The article is summarized in a bullet list.
I am not able to see why tr is behaving surprisingly strange.
I am pasting the commands and output. see if anyone can explain the mystery.

secconfig(8) System Manager's Manual secconfig(8)NAME
secconfig, secsetup - Security features setup graphical interface (Enhanced Security)
SYNOPSIS
/usr/sbin/sysman secconfig
NOTE: The secsetup utility has been replaced by the secconfig graphical interface.
DESCRIPTION
The utility is a graphical interface used to select the level of system security needed. It can convert from Base to enhanced security
mode, and configure base and enhanced security features. If you are using secconfig to enable Enhanced security, you must first have
loaded the enhanced security subsets.
You can run while the system is in multiuser mode. However, if you change the security level, the change is not completed until you reboot
the system.
For both base and enhanced security, the secconfig utility allows you to enable segment sharing, to enable access control lists (ACLs), and
to restrict the setting of the execute bit to root only.
For enhanced security, the secconfig utility additionally allows you to configure security support from simple shadow passwords all the way
to a strict C2 level of security. Shadow password support is an easy method for system administrators, who do not wish to use all of the
extended security features, to move each user's password out of /etc/passwd and into the extended user profile database (auth.db. You can
use the Custom mode if you wish to select additional security features, such as breakin detection and evasion, automatic database trimming,
and password controls.
When converting from base to enhanced security, secconfig updates the system default database (/etc/auth/system/default) and uses the con-
vuser utility to migrate user accounts.
While it is possible to convert user accounts from enhanced back to base, the default encryption algorithms and supported password lengths
differ between base and enhanced security, and thus user account conversions do not succeed without a password change.
NOTE: Because of the page table sharing mechanism used for shared libraries, the normal file system permissions are not adequate to protect
against unauthorized reading. The secconfig interface allows you to disable segment sharing. The change in segment sharing takes effect
at the next reboot.
