Maggie, Carys and about two dozen other Girl Scouts were participating in a workshop at Northern Trust’s Loop office on a Saturday morning earlier this month to earn their cybersecurity badges. Girl Scouts earn badges or other awards once they’ve explored a topic or learned a new skill. The cybersecurity badges, introduced for girls in kindergarten through fifth grade earlier this year, are part of an effort from the Girl Scouts of the United States of America to increase participation in STEM fields, which have long been dominated by men.
