The Ministry of Defence and the Defence Forces have been working on a cyberwarfare and defence formation for some years now. In 2007, a military doctrine of an e-military of Estonia was officially introduced as the country was under massive cyberattacks in 2007. The proposed aim of the e-military is to secure the vital infrastructure and e-infrastructure of Estonia. The main cyber warfare facility is the Computer Emergency Response Team of Estonia (CERT), founded in 2006. The organisation operates on security issues in local networks.
