Embedded systems control much of the world's critical infrastructure, which makes them a prime target for attack by everyone from hackers to terrorists. Embedded systems, however, have at their disposal an impressive set of defenses, mechanisms and procedures that are in common use for operations other than security, but that result in security mechanisms that prove stronger in some cases than traditional enterprise systems like Windows or Linux. In the early days of my career as an embedded-systems developer, I worked on critical communications systems. Every aspect of the software and hardware had to be perfect-any failure could prove disastrous. Couple this with the fact that updating software sometimes involved climbing hurricaneproof towers in the Everglades, brushing aside various lizards and insects, then manually plugging in PROMs, and you had a team of people highly motivated to get it right the first time.

"The protection mechanisms of current mainstream operating systems are inadequate to support confidentiality and integrity requirements for end systems. Mandatory access control (MAC) is needed to address such requirements, but the limitations of traditional MAC have inhibited its adoption into mainstream operating systems. The National Security Agency (NSA) worked with Secure Computing Corporation (SCC) to develop a flexible MAC architecture called Flask to overcome the limitations of traditional MAC. The NSA has implemented this architecture in the Linux operating system, producing a Security-Enhanced Linux (SELinux) prototype, to make the technology available to a wider community and to enable further research into secure operating systems. NAI Labs has developed an example security policy configuration to demonstrate the benefits of the architecture and to provide a foundation for others to use.

XML Encryption provides end-to-end security for applications that require secure exchange of structured data. XML itself is the most popular technology for structuring data, and therefore XML-based encryption is the natural way to handle complex requirements for security in data interchange applications. Here in part 1 of this two-part series, Bilal explains how XML and security are proposed to be integrated into the W3C's Working Draft for XML Encryption. Currently, Transport Layer Security (TLS) is the de facto standard for secure communication over the Internet. TLS is an end-to-end security protocol that follows the famous Secure Socket Layer (SSL). SSL was originally designed by Netscape, and its version 3.0 was later adapted by the Internet Engineering Task Force (IETF) while they were designing TLS. This is a very secure and reliable protocol that provides end-to-end security sessions between two parties. XML Encryption is not intended to replace or supersede SSL/TLS. Rather, it provides a mechanism for security requirements that are not covered by SSL. The following are a two important areas not addressed by SSL: * Encrypting part of the data being exchanged * Secure sessions between more than two parties With XML Encryption, each party can maintain secure or insecure states with any of the communicating parties. Both secure and non-secure data can be exchanged in the same document. For example, think of a secure chat application containing a number of chat rooms with several people in each room. XML-encrypted files can be exchanged between chatting partners so that data intended for one room will not be visible to other rooms.
