Hi, I am going through the Selinux guide and had this question about the Bell-LaPadula model.
It says read down and write up. Just wanted to clarify as to is this secure. A lower security subject writing to a higher priority object can cause one to alter binary files and use them according to convenience. For E.g. a hacker could write a modified version of passwd command and replace the original one. Please clarify.
