SC Congress Toronto: CISOs must approach security as a strategy

To gain the most headway inprotecting their organizations from advanced threats, security management must take on a gatekeeper” approachto defend corporate data, said Jack Danahy, director for North American security consulting and delivery atIBM, who presented a keynote address Tuesday at the annual SC CongressCanada 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 tospot 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,' isending,” he told attendees.

In yearspast, the expectation among management was to nullify threats or breaches, butwith the advanced tactics used by hackers today, like sending spear phishingemails to specific employees to gain access to corporate networks, thefocus 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,he explained.   

Big Data analysis, which incorporates a more holistic approach inassessing information and risks on company networks, is a good place to start.

He also discussed how CISOs often face challenges in effectively communicatingrisks to other company executives because security pros are stilllearning to move away from a purely technical way of delivering threat informationto their colleagues.

“The CISO is a newbie,” he said.

Often times, CISOs emerge from an IT background where they've worked more on thetechnical side of issues, and their relationships with C-level management mayhave 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 managementthat hold the purse strings for businesses.
