Book excerpt: Information and communication technologies are increasingly prevalent in electoral management and democratic processes, even for countries without any form of electronic voting. These technologies offer numerous new opportunities, but also new threats. Cybersecurity is currently one of the greatest electoral challenges. It involves a broad range of actors, including electoral management bodies, cybersecurity expert bodies and security agencies. Many countries have found that interagency collaboration is essential for defending elections against digital threats. In recent years significant advances have been made in organizing such collaboration at the domestic and international levels. This guide tracks how countries are making progress on improving cybersecurity in elections. Based on an extensive collection of 20 case studies from all over the world, it provides lessons for those wanting to strengthen their defences against cyberattacks.
