- Consider a system in which four processes (A,B,C,D) are attemptign to access four types of resource (1,2,3,4). There are two instances of each type of resource , and the current allocation is <1001> for A , <0101> for B , <1000> for C , and <0010> for D. The Max Need for each process is <2002> for A , <0202> for B , <1100> for C , and <1010> for D. Is this system state safe? If so give an order in which the processes can be satisfied (written without spaces or commas , like ABCD); if not give an order ih which all processes that can be satisfied are serviced ending with an X (again written without spaces or commas , like ABX ; if none can be satisfied , just write X)

Part B (10) Deadlock Avoidance Consider the following maximum-claim reusable resource system with four processes and three resource types. The maximum claim matrix is given by C [4 3 5 11 1 41 1 4 6 13 1 6] where Cij denote maximum claim of process i for resourcej. The total units of each resource type are given by the vector (5, 8, 15). The current allocation of resources is given by the matrix To 1 4] 2 0 1...

In order to prevent deadlocks, let a system adopt the policy of forcing processes to request resources in ascending order of request type rank. In particular, when a process is requesting a resource of a certain type, the process cannot be holding other higher ranked resources. Consider four resource types with the following profile in this system: Resource Type Rank Number of Instances RT1 4 2 RT2 7 4 RT3 8 3 RT4 10 2 Let the following sequence of...

Risk management in Information Security today Everyday information security professionals are bombarded with marketing messages around risk and threat management, fostering an environment in which objectives seem clear: manage risk, manage threat, stop attacks, identify attackers. These objectives aren't wrong, but they are fundamentally misleading.In this session we'll examine the state of the information security industry in order to understand how the current climate fails to address the true needs of the business. We'll use those lessons as a foundation...
