The Ministry of Defence has technical and procedural measures in place to protect it from, and mitigate, the impact of cyber attacks, as it does other threats and risks. The MOD conducts exercises to test these measures both internally, and with other Government agencies and our allies. Technical and procedural measures are constantly reviewed to reflect the dynamic nature of the threats. We do not comment on the detail of such protective measures in order not to provide information that could be exploited by a potential attacker.
