EAL4
The Evaluation Assurance Level (EAL1 through EAL7) of an IT product or system is a numerical grade assigned following the completion of a Common Criteria security evaluation, an international standard in effect since 1999. The increasing assurance levels reflect added assurance requirements that must be met to achieve Common Criteria certification. The intent of the higher levels is to provide higher confidence that the system's principal security features are reliably implemented. The EAL level does not measure the security of the system itself, it simply states at what level the system was tested. To achieve a particular EAL, the computer system must meet specific ''assurance requirements''. Most of these requirements involve design documentation, design analysis, functional testing, or penetration testing. The higher EALs involve more detailed documentation, analysis, and testing than the lower ones. Achieving a higher EAL certification generally costs more money and takes more ...

XTS-400
The XTS-400 is a multilevel security, multilevel secure computer operating system. It is multiuser and computer multitasking, multitasking that uses multilevel scheduling in processing data and information. It works in networked environments and supports Gigabit Ethernet and both Internet Protocol version 4, IPv4 and IPv6. The XTS-400 is a combination of x86, Intel x86 hardware and the Secure Trusted Operating Program (STOP) operating system. XTS-400 was developed by BAE Systems, and originally released as version 6.0 in December 2003. STOP provides ''high-assurance'' security and was the first general-purpose operating system with a Common Criteria assurance level rating of EAL5 or above. The XTS-400 can host, and be trusted to separate, multiple, concurrent data sets, users, and networks at different sensitivity levels. The XTS-400 provides both an ''untrusted'' environment for normal work and a trusted operating system, trusted environment for administrative work and for pr ...
