Talking Cybersecurity From A Risk Management Point of View

CenturyLink CSO David Mahon reflects on the evolution of the chief information security officer, and why today's CISOs are increasingly adopting a risk-based approach to security.

Dave Mahon, Chief Security Officer, CenturyLink
R. David (Dave) Mahon was named chief security officer in April 2011 for CenturyLink, the third-largest communications provider in the U.S. In addition to his CSO role, McMahon is also the company's liaison with the National Security Telecommunications Advisory Council (NSTAC), National Cybersecurity and Communications Integration Center (NCCIC), as well as federal and state law enforcement and homeland security agencies.

Prior to joining CenturyLink, Mahon was a supervisory special agent with the FBI responsible for investigating violations of federal statutes in which the Internet, computer systems, and networks were exploited as the targets of terrorist organizations, foreign government-sponsored intelligence operations or criminal activities.

A Quarter Right.
Missing inventory is a core failure in firms that avoidable damages their essential risk management: missing data criticality and,missing wanted software inventory. From this the strongest single control of alerting on other than wanted motions of critical data or detecting other than wanted software is lost. This area is essentially about detecting and shrinking the impact of an adverse event. But, inventory also extends to the vulnerable attack surface. The rate of attack generally follows the number of at risk computers. Suppose it is true that industries have reliable trends in the number of computers per staff. The attack surface or rate of damaging attacks per year would grow as the firm grows. A considerable amount of skipping inventory of vulnerable computers, excess inventory of online accessible sensitive data, vendors selling known vulnerable systems getting full price for their wares, skipper hardening of software and configurations a like occur. Consider the number of vendors slow to fix SSL/TLS vulnerabilities even if they knew is was essential to fix for credit card data protection since April 2015. I agree that missing inventory of sensitive data is important. But that is one quarter right. What of missing wanted software inventory, at risk data inventories, avoidablyou vulnerable system inventories? Few firms have any idea what their mean time to repair vulnerabilites really is, what it's 95th confidence interval is or even the avoidable risk created by under funding the resolution or circumventing of automation actually costs them. I can assure you a grocery store manager knows more about the cost of business disruption of the freezer section than many firms know of their business disruption costs due to avoidable vulnerabilty of unwise full price purchase prices paid for known vulnerable software.
