Security & Risk (S&R) chiefs and Infrastructure & Operations (I&O) leaders have a lot in common, and in great companies, we work in concert to run an efficient, reliable technology infrastructure that keeps critical business assets safe. Much has changed in the world of technology since I pulled my first all-nighter in a data center (falling asleep next to the EMC Symmetrix array was not one of my better ideas \u2013 those corners were sharp!), but that partnership is still the same \u2013 it takes security engineers and network\/server engineers working together to solve really thorny problems.We have our frictions, of course \u2013 I&O pros prioritize operational stability and continuity of service, while S&R pros must occasionally interrupt that continuity to contain security breaches. But when a serious incident (whether security breach or system failure) threatens to sideline our business systems, it falls to us to find and fix the problems \u2013 together. We may be organizationally separate now, with I&O reporting into the CIO and the CISO reporting into a COO or Head of Operational Risk, but we share a set of fundamental challenges. \u00a0We must excel in our own domains (not exactly a cakewalk) but also anticipate and deliver on what our businesses need (much harder).\u00a0And what our businesses seek today is growth \u2013 in Forrester\u2019s most recent survey of business decision-makers, the top two priorities were growing overall company revenue and acquiring and retaining customers. S&R pros have already worked hard to escape their \u201cDepartment of No\u201d reputations, and I&O pros have labored tirelessly to get out of the data center and into the business.\u00a0But that\u2019s not enough.\u00a0 As CISOs and I&O leaders, we must help our firms: 1) win and serve customers; 2) expand into new geographies; 3) form new relationships with distributors, suppliers, and financiers (the extended enterprise); and 4) deliver top-notch customer service.\u00a0We must be an integral part of our companies\u2019 efforts to differentiate and grow.\u00a0For S&R, that means becoming the \u201cDepartment of Yes, And Here\u2019s How.\u201d And for I&O, that means thinking about, and indeed, even obsessing about, the end customer.\u00a0Laura Koetzle is a vice president and practice leader at Forrester Research, where she serves Security & Risk and Infrastructure & Operations Professionals. She will be chairing Forrester's Security Forum and Infrastructure & Operations Forum on November 9-10 in Miami, FL.
