The security of a lottery plays a critical role in maintaining the confidence and trust of the public in its lottery games. It is vital, therefore, that a lottery organization develops and maintains a visible and documented security environment in order to achieve and sustain public confidence in its operations.

The WLA SCS is the lottery sector's only internationally recognized security standard. The WLA SCS couples a comprehensive information security management baseline incorporating ISO/IEC 27001:2005, a leading international standard for information security management, with additional lottery-specific security controls representing current best practice. The WLA SCS is designed to assist the lottery sector around the globe in obtaining a level of security controls in line with generally accepted best practices, to enable an increased reliance on the integrity of lottery operations. The WLA SCS specifies the required practices for an effective security management structure by which a lottery may maintain the integrity, availability, and confidentiality of information vital to its secure operation.
