“CISO” stands for “Chief Information Security Officer,” the executive in charge of protecting an organization’s information assets: in other words, the head cybersecurity person. CISOs often are also responsible for customer privacy, compliance with data protection regulations, and other related issues. The position has grown and evolved rapidly in the last 15 years or so; today, the vast majority of large companies have an equivalent executive position. President Obama established the first U.S. federal government CISO in 2016.
Reading material aimed at CISOs and similar executives is a great way to get a birds-eye view of emerging and ongoing cybersecurity issues. Berkeley tends not to subscribe to practitioner-oriented publications such as MLex, but a few are available to us. The Berkeley community has a site license to Bloomberg BNA and Gartner analyses, and free accounts are available to students for the Wall Street Journal, Financial Times, and the New York Times, all of which cover cybersecurity to some degree.
