Bundled security tools

Privacy Enhanced Mail (PEM) was the first serious effort to secure Internet mail. The Internet Resources Task Force (IRTF) Privacy and Security Research Group (PSRG) did the initial design. The Internet Engineering Task Force (IETF) PEM Working Group continued development for three years, resulting in a four- part Proposed Internet Standard published in early 1993 [64] [56] [5] [55]. PEM is a broad standard suite, it provides encryption, authentication, message integrity and key management. PEM supports both symmetric and asymmetric (public- key) key management schemes.

What does a typical BCS network look like? Most installations today have a dedicated BCS network with centralized control via an operator’s terminal in the facility manager’s office. There is no Internet (or LAN) connection, and thus no IT threat. However, the trend today is toward greater connectivity to enable new services, convenience, and savings on infrastructure costs. Newer buildings have network connections to the Inter- net. But even so, most BCS networks still have few resources that are of value to the typical “hacker”. ...
