The Computer Emergency Response Team of Mauritius (CERT-MU) organised a National Cybersecurity Drill for the Financial Sector and the Department of Civil Aviation from 25th – 28th June 2019 at Palms Hotel, Quatre-Bornes. The main objective of the 4 days’ event was to assess the preparedness of these sectors to resist cyber threats and enable timely detection, response, and mitigation and recovery actions in the event of cyber-attacks. A workshop was held on the 25th June 2019 to familiarize the participants with the way cybersecurity drills are conducted and what is expected from them. The participants were also informed on the team composition for the drill exercise. From 26th – 28th June 2019, various scenarios were simulated during the drill exercise where participants had to come up with their response plans and present same in front of the other teams. The scenarios were conducted by staffs of CERT-MU during these 3 days. We also had a team of 3 Estonian experts from the Cyber4D programme who acted as observers for the cybersecurity drill.
