In the past two years, cybersecurity has become a leading buzzword – if not the leading buzzword – in the hedge fund compliance community. In recent months, the cyber focus has become even more intense for the hedge fund industry, as every week seems to bring a new major cyber regulatory development. Consequently, keeping up with cyber compliance news is challenging for hedge fund compliance personnel. Regulators have done a tremendous job of sharing principles-based guidance with the compliance community, clarifying regulatory expectations to assist firms with respect to cybersecurity. In a guest article, the first in a two-part series, Moshe Luchins, the deputy general counsel and compliance officer of Zweig-DiMenna Associates LLC, provides hedge fund compliance professionals with an outline of the regulatory expectations in the area of cybersecurity. The second article will provide hedge fund managers with a practical blueprint to build a cyber-compliance program.
