Given the nature of cyber warfare, there is some debate as to whether all cyber attacks trigger the applicability of IHL and – a distinct but related question – whether they constitute “ attacks” for the purposes of IHL. IHL only applies to cyber operations that occur during – or that themselves trigger – an armed conflict. Cyber operations may be either offensive or defensive.
The term cyber warfare refers to means and methods of warfare that rely on information technology and are used in situations of armed conflict.
