"IT Governance requires public and corporate cybersecurity policies to improve fighting against cybercrime and other violations. The EU, the USA and Brazil have recently developed different regulatory approaches on the subject. Assessing how to design policies in line with them across geographies seems key for effectively managing relevant global issues. After a brief introduction, the article touches on three sample topics: online privacy, open-source platforms, and latest-generation cyber-threats to illustrate how EU, US and Brazil have taken different paths. Each sample topic is analysed in detail and followed by a conclusion indicating how possibly regional or national particularities may be pragmatically reconciled by public and corporate interested parties."
