6, April 2000 ECS 253 Spring 2000 Page 1 Outline for April 6, 2000 1. 2. Greetings and felicitations! a. Handouts ACM and primitive operations a. Go over subjects, objects (includes subjects), and state (S, O, A) where A is ACM b. Transitions modify ACM entries; primitive operations follow c. enter r into A[s,o] d. delete r from A[s,o] e. create subject s (note A[s ,x] = A[x,s ] = for all x) f. create object o (note A[x,o ] = for all x) g. destroy subject s h. destroy object o commands a. command c(s1, ..., sk, o1, ..., ok) if r1 in A[s1, o1] and r2 in A[s2, o2] and ... rm in A[sm, om] then op1; op2; ...; opn; end. b. Example 1: creating a le command create_ le(p, f) create object f; enter Own into A[p, f] enter Read into A[p, f] enter Write into A[p, f] end. c. Example 2:granting one process read rights to a le command grant_read(p, q, f) if Own in A[p, f] then enter Read into A[q, f] end. What is the safety question? a. An unauthorized state is one in which a generic right r could be leaked into an entry in the ACM that did not previously contain r. An initial state is safe for r if it cannot lead to a state in which r could be leaked. b. Question: in a given arbitrary protection system, is safety decidable? Mono-operational protection systems: decidable a. Theorem: there is an algorithm that decides whether a given mono-operational system and initial state is safe for a given generic b. right. Proof: nite number of command sequences; can eliminate delete, destroy. Ignore more than one create as all others are conditioned on access rights in the matrix. (One exception: no subjects; then we need one create subject). Bound: s number of subjects (possibly one more than in original), o number of objects (same), g number of generic rights; number of command sequences to inspect is at most 2gso. General case: It is undecidable whether a given state of a given protection system is safe for a given generic right. a. Represent TM as ACM; reduce halting problem to it 3. 4. 5. 6.

Show bridges (as a combination of terminal and initial spans) c. Show islands (maximal subject-only tg-connected subgraphs) d. can share(r, x, y, G0) iff there is an edge from x to y labelled r in G0, or all of the following hold: (1) there is a vertex y with an edge from y to y labelled r; (2) there is a subject y which terminally spans to y , or y = y ; (3) there is a subject x which initially spans to x, or x = x; and (4) there is a sequence of islands I1, ..., In connected by bridges for which x is in I1 and y is in In . e. Describe can steal; don t state theorem Last modified at 11:22 pm on Saturday, May 13, 2000
