SC Congress Toronto: CISOs must approach security as a strategy
To gain the most headway in
protecting their organizations from advanced threats, security management must take on a “gatekeeper” approach
to defend corporate data, said Jack Danahy, director for North American security consulting and delivery at
IBM, who presented a keynote address Tuesday at the annual SC Congress
Canada in Toronto.
As threats become more sophisticated, and businesses allow expanded access to their networks due to trends like bring-your-own-device
(BYOD), CISOs will have to balance blocking attacks with strategically planning to
spot and respond to them when they inevitably occur, said Danahy, who previously founded and sold two start-ups, Ounce Labs and Qiave Technologies.
“Our job as the gatekeeper who [only] says, 'No,' is ending,” he told attendees.
past, the expectation among management was to nullify threats or breaches, but
with the advanced tactics used by hackers today, like sending spear phishing
emails to specific employees to gain access to corporate networks, the
focus becomes knowing who your enemy is and what they want.
Now that companies are facing attackers who “stockpile zero-days,”
patching isn't necessarily going to solve the problem. Instead, management must think more strategically about reducing enterprise exposures,
Big Data analysis, which incorporates a more holistic approach in
assessing information and risks on company networks, is a good place to start.
He also discussed how CISOs often face challenges in effectively communicating
risks to other company executives because security pros are still
learning to move away from a purely technical way of delivering threat information
to their colleagues.
“The CISO is a newbie,” he said.
Often times, CISOs emerge from an IT background where they've worked more on the
technical side of issues, and their relationships with C-level management may
have involved a middle man.
To climb these hurdles, CISOs should build an amicable relationship with their CIOs, who are used to sharing technological concerns with CFOs, CEOs and management that hold the purse strings for businesses.
