Special Report: Marketplace Security Survey, Risky Business - 36

MAINFRAME SECURITY SURVEY

from outside threats. Monitoring
cloud security infrastructure was
a concern for 57.2 percent. Others
included maintaining regulatory
compliance (48.8 percent),
monitoring workloads across
multiple cloud infrastructures
(34.7 percent) and monitoring
cloud-based network data traffic
patterns (29.4 percent). See the
results in Figure 3 on page 38.
"One of the things people are
doing to mitigate risk is leveraging
hybrid clouds," Sardino says.
"They may have application
components in this environment
or use software as a service that
connects securely back to the
system of record. This allows
you to have a layered approach
to security with sensitive data
residing on the mainframe and
other, less sensitive data and
applications on the cloud."
According to Shay, mainframe
cloud is generally just as secure
as non-cloud, mainframebased resources. Cloud-based
mainframe data typically resides
in a secure data center, leaving
the data center on secure lines or
a VPN, much as non-cloud data
runs through secure networks
within home data centers. As
far as he's concerned, "security
concerns for mainframe clouds
are exactly the same as non-cloud
implementations."

Removing Barriers
Many organizations have
similar concerns about mobile

computing. Among their reservations, according to the survey,
are data privacy (74.9 percent),
access control (64.2 percent),
mobile device loss or theft
(50.7 percent), third-party
mobile apps (43.1 percent) and
compliance (32.7 percent).
"It would just kill me if I lost
my phone and all of the personal
data I have on it was misused,
but that's just the tip of the
iceberg," King notes. "Take a
car rental agency, for example.
It might use tablets in the field
when checking cars in and out,
and those devices likely have
access to a lot of back-end data,
such as personal customer
data and credit card numbers.
If someone gets ahold of those
devices, he can do more damage
than you know."

"You can't just get a certificate and
automatically call yourself an expert.
It takes years and years of experience
to get to that level."
-Stan King, CTO, Information Technology Co.

Shay sees mobile devices as
just another method to access
the mainframe. Already, capabilities exist to provide secure
access for authorized users with
a smartphone or tablet. "You
just need to do your homework,"
he adds.
Encryption is one way to
address concerns regarding both
cloud and mobile. The majority of
survey respondents report having
some type of encryption in place,
for a total of 71.4 percent (33.6
percent symmetric and 37.8
percent asymmetric). However,
28.7 percent have no encryption
technologies in place.
This is a startling number,
given the built-in encryption
capabilities of z Systems, both at
the hardware and z/OS* levels.
Part of this could be due to
perceived complexities or
uncertainty about what to
encrypt. The general consensus
regarding the latter is to perform
an inventory of what's most
sensitive and encrypt that, both
at rest and when it's in motion.
In some cases, organizations
are concerned they might have to
rewrite applications to allow for
encryption. Some tools-such as
