I have searched wiki for pseudo tty devices but it was very complex for me to understand.
Can any one help me understanding concept behind pseudo-tty in layman language?
According to security manual of our org /etc/securetty files shouldn't have any pseudo tty devices.

rusage(1B) SunOS/BSD Compatibility Package Commands rusage(1B)
NAME
rusage - print resource usage for a command
SYNOPSIS
/usr/ucb/rusage command
DESCRIPTION
The rusage command is similar to time(1). It runs the given command, which must be specified; that is, command is not optional as it is in
the C shell's timing facility. When the command is complete, rusage displays the real (wall clock), the system CPU, and the user CPU times
which elapsed during execution of the command, plus other fields in the rusage structure, all on one long line. Times are reported in sec-
onds and hundredths of a second.
EXAMPLES
Example 1: The format of rusage output
The example below shows the format of rusage output.
example% rusage wc /usr/share/man/man1/csh(1)
3045 13423 78071 /usr/share/man/man1/csh(1)
2.26 real 0.80 user 0.36 sys 11 pf 38 pr 0 sw 11 rb 0 wb 16 vcx 37
icx 24 mx 0 ix 1230 id 9 is
example%
Each of the fields identified corresponds to an element of the rusage structure, as described in getrusage(3C), as follows:
real elapsed real time
user ru_utime user time used
sys ru_stime system time used
pf ru_majflt page faults requiring physical I/O
pr ru_minflt page faults not requiring physical
I/O
sw ru_nswap swaps
rb ru_inblock block input operations
wb ru_oublock block output operations
vcx ru_nvcsw voluntary context switches
icx ru_nivcsw involuntary context switches
mx ru_maxrss maximum resident set size
ix ru_ixrss currently 0
id ru_idrss integral resident set size
is ru_isrss currently 0
