IBM Systems Magazine, Mainframe - January/February 2017 - SE32
SECURE FROM THE
METAL ON UP
Clients can breathe easier knowing security is built into the mainframe
ecurity breaches have become common, whether caused by
external cybercriminals who purposely attack a system or by
an employee who mistakenly deletes data.
According to a mainframe security survey conducted by IBM
Systems Magazine, 54 percent of respondents are very concerned
about security and 36 percent have some concern. Only 9.6 percent
of respondents said security wasn't an issue.
Business operations often drive security strategies. Reasons cited
by respondents for instituting security programs are compliance
(69 percent); best practices (68 percent); a risk-based framework
(52 percent); cost-value analysis (27 percent); previous cyberattacks
(25 percent); and board recommendations (14 percent).
A Proactive Approach
While legal compliance mandates are a big reason companies
embark on security programs, "another is having data the bad
guys are interested in-and the need to protect that," says
Nick Sardino, security offering manager, IBM z Systems*. (See
"Unauthorized Users and External Hackers Are Top Concerns Cited
in Mainframe Security Survey," ibmsystemsmag.com/mainframe/
trends/security/risky-business-survey/.) If companies don't have
security programs in place, "they risk reputational damage and
financial losses," he explains. "If your
bank gets breached, for example, it's
likely to offer credit monitoring and other
mitigation services, and real costs are
associated with that. Plus, everyone wants to keep themselves
out of the newspapers."
Security is Top of Mind
Security is built into the z Systems platform, thanks to its end-to-end
integration. The platform's structure was designed with security
in mind to keep your data safe.
"The mainframe can isolate one operation from another in
such a way that they're invisible to each other," says Bernard
Meyerson, IBM Fellow and vice president, innovation. "This is
a tremendous security feature, and few can actually use that
famous word 'ensure.' Not 'hope,' not 'wish,' but 'guarantee.'
And this isn't overblown. It's simply a fact," he states. (See "How
Mainframe Innovations Have Helped Shape and Reshape the
IT World," ibmsystemsmag.com/mainframe/Business-Strategy/
The mainframe also takes advantage of analytics-based security
tools that continuously run analytics to spot a potential cyberattack.
"You can't look for a specific line of code to warn you of an attack,
as attacks now often employ first-of-a-kind code, thus defeating
traditional defenses," Meyerson says. "Instead, you use code
that renders your system self-aware, always on the lookout for
suspicious behavioral attributes."
The z Systems platform works hard to
keep your data and operations safe so
you can breathe easier.
