Close coordination among law enforcement agencies, researchers, and intelligence agencies is required to solve the problem of computer crime. There are several barriers to this cooperation including asymmetric laws, national interests, and poor communication mechanisms. Computers have not only led to new types of crimes, but have provided additional avenues for existing crimes. Laws for traditional crimes have not evolved quickly enough to accommodate technology developments. To foster increased cooperation, it is necessary to have a common vocabulary, which will avoid confusion in interpretation of laws, security policies, data, and research due to differences in language, vocabulary, and semantics. The basic premise of the paper is that security policies are the key instrument of security that will help in tacking international cybercrime and a shared vision of security would be achieved through common security policies. This paper presents recommendations and results from the creation of an initial security glossary compiled from public sources on the Internet as a part of research in developing metrics for information security policies. The large variation in terminology and definitions underscores the necessity of standardization of nomenclature in security.
