I have been reading on security policies and the question wether Bell-LaPadula can be used to implement Chinese Wall. Does anyone know more about it?

Please outline how you think the simulation should work. As it is, the question is a little trite. –  Raphael Apr 23 '12 at 6:35

There is a comparison between Chinese Wall & BLP in the paper by Brewer & Nash. Is it part of the answer ? –  Romuald Apr 23 '12 at 12:51
    
actually i found the answer by reference book (Computer Security: Art and Science By Matt Bishop)(chapter 7 section 1) suggested by my friend - first the Bell-LaPadula Model cannot capture changes over time. second, more serious problem arises when one considers that subjects in the Chinese Wall model may choose which CDs(company dataset) to access; in other words, initially a subject is free to access all objects. the Bell-LaPadula Model cannot emulate the Chinese Wall model. –  siddharth Apr 24 '12 at 6:04
    
@siddharth, would you like to make your comment the answer? –  Merbs Nov 27 '12 at 17:32
    
@Raphael, if siddharth doesn't answer, can you shift his comment into an answer? –  Merbs Nov 27 '12 at 17:33
