Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Chegg and its Board recognize the critical importance of maintaining the trust and confidence of our students, business partners, and employees. We have established an ISP utilizing the National Institute of Standards and Technology Cybersecurity Framework as an authoritative source of cybersecurity standards and framework for measurement. The ISP is comprised of the following components: (i) policies which describe the core requirements and design aspects of the program, (ii) standards that provide quantifiable and prescriptive requirements to meet the program's design, (iii) processes that provide operational requirements to meet the ISP's policies and standards consistently, and (iv) implementation playbooks which are created, maintained, and used by the respective team responsible for implementation. The ISP has three core functions underlying its design, which are intended to provide Chegg with appropriate oversight and governance to execute, monitor, measure and report on the performance of the program in a consistent manner: •management (control owners) have a responsibility to own and manage risks associated with day-to-day operations, including the design, implementation, and ongoing operation of controls; •compliance and cybersecurity teams enable the identification of emerging risks in daily operation of our business, providing compliance and oversight in the form of frameworks, policies, tools, and techniques to support management; and •third-party independent assessors provide objective evaluation by assessing whether the first and second functions above are operating successfully, providing assurance that controls are effective in both design and operation.
