What are the evaluation levels defined by the TCSEC?
What will be an ideal response?
The TCSEC defined a range of evaluation levels, and these levels are the government evaluation levels that we encounter today. A higher level indicates incorporation of the lower level's requirements or replacement of a particular requirement with a stronger requirement. Each level is represented by an alphanumeric code, A1 being highest and D being lowest:
D - The lowest level assigned to evaluated products.
C1 - A single-user system; this level is not used today.
C2 - Multi-user systems such as UNIX, Linux, or Windows. Versions of Windows had earned this level.
C3 - An enhanced multi-user system; this level is not used today.
B1 - The lowest level of evaluation for a system with MLS capability.
B2 - An MLS system with basic architectural assurance requirements and covert channel analysis. Details on covert channels are provided later.
B3 - An MLS system with more significant assurance requirements, including formal specifications.
A1 - A full MLS system with design proved correct mathematically.
