Given the security levels TOP SECRET, SECRET, CONFIDENTIAL, and UNCLASSIFIED (ordered from highest to lowest), and the categories A, B, and C, specify what type of access (read, write, both, or neither) is allowed in each of the following situations. Assume that discretionary access controls allow anyone access unless otherwise specified. Additionally if the subject cannot read or write the object, then give one object classification that the subject can read or write (excluding the subject's own clearance). a. Paul, cleared for (TOP SECRET, {A, C}), wants to access a document classified (SECRET, {B, C}).
b. Anna, cleared for (CONFIDENTIAL, {C}), wants to access a document classified (CONFIDENTIAL, {B}).
c. Jesse, cleared for (SECRET, {C}), wants to access a document classsified (CONFIDENTIAL, {C}).
d. Sammi, cleared for (TOP SECRET, {A, C}), wants to access a document classsified (CONFIDENTIAL, {A}).
e. Robin, who has no clearances (and so works at the UNCLASSIFIED level), wants to access a document classified (CONFIDENTIAL, {B}).
