Growing cybersecurity demands on companies require effective reporting lines and operational structures to manage cybersecurity-related job functions. Experts agree that it is optimal to have both a Chief Cybersecurity Officer or Chief Information Security Officer (CISO) and a separate Chief Privacy Officer (CPO). Some companies confuse these positions, thinking “that the security person should know all things privacy and the privacy person should know all things security, and that is clearly not the case,” Michael Overly, a partner at Foley & Lardner told the Cybersecurity Law Report. In this two-part article series, we define and distinguish the roles of the CPO and CISO. Part One focuses on the CISO – including core responsibilities, best practices for structuring reporting lines, and considerations when hiring for the position – and Part Two will focus on the CPO.
