Are PASSWORDS Passe?
RACF offers different options to ensure a secure IBM Z system

O

nce upon a time, it was easy to secure a z/OS* (e.g., MVS) system. Users were
defined, passwords were created and data sets were protected. Users accessed
the mainframe from terminals connected directly to it. Now consider today's
environment. Users are accessing the mainframe from different places and devices.

specialist with
IBM Security.

IBM Z* systems host
mission-critical corporate
information and production
applications for banking, financial
services, healthcare, government
and retail companies that require
highly secure systems.
Passwords are critical
gatekeepers to our digital
identities, allowing us to access
online shopping, dating, banking,
social media, private work and
life communications. They can
present a relatively simple point
of attack for hackers to exploit.
For systems like the IBM Z
platform that rely on passwords

to be secure, they must enforce
password controls and provide
user education. Users tend to pick
common passwords, write down
passwords and unintentionally
install malware that can key log
passwords. Good passwords are
hard to remember. Many times
people pick passwords that are
either patterns or are simple.
While a password like 9$Ff2%^*(
may be strong, this leads to another
problem: Good passwords are
often written down to help the
user remember. Or, a user reuses
the password or makes a minimal
change to it. Passwords can be

forgotten. Now think about this:
How many passwords do you have?

Secure RACF
Password Suggestions
Thinking about passwords and
more specifically in RACF*-since
it provides authentication options
for the mainframe-various
options can be used to strengthen
password complexity. Some
options include:
*

Having RACF set up to have
a password length of eight
characters that's made up
of uppercase letters, digits
