Security in Electronic Messaging Systems
Diana M. D'Angelo, Bruce McNair, Joseph E. Wilkes · AT&T Technical Journal · 1994
Electronic messaging systems are quickly overtaking paper-based systems, not only in large businesses, but also in small businesses, residential offices, and the consumer marketplace. As they do, the security of electronic messaging will become an ever-increasing issue. Large businesses typically have a complete infrastructure in place to deal with security issues. Small businesses, however, are just beginning to use electronic messaging and electronic payment systems, and residential office users and consumers have generally had no exposure to this level of technology. This paper describes both the historical background of security controls in paper-based systems, and the current market needs, technology, standards, and future directions of security controls in electronic messaging systems.
