A group of people interested in advancing a given area of knowledge, technology or culture. SIGs function cooperatively and are solutions oriented. Members share ideas and may hold meetings and organize conferences. Some SIGs are also advocacy groups (political groups, for example) in which members have a common objective or agenda. SIGs formed by the PCI SSC provide an opportunity for member organizations and individual council members to share their business and technical expertise in the global effort to apply the PCI DSS and related standards to specific industries or technological issues.
