Consider a file server where a user is allowed to download files. Each file has an access control list of the users that are allowed to download the file. The security policy is that only users listed in the access control list can download the file. List the information that must be logged by a system that audits this policy.
Computer Science Operation System question. I will give thumb up, thank you! Consider a file system that uses inodes to represent files. This file system has 16 direct disk blocks, as well as single, double, and triple indirect disk blocks. This file system is illustrated in the below figure. Please notice that the tables pointed to by the indirect pointers are full sized blocks that only stores pointers. mode owners (2) timestamps (3) size block count data data data direct...
Java Netbeans code Option 1: Authentication System For security-minded professionals, it is important that only the appropriate people gain access to data in a computer system. This is called authentication. Once users gain entry, it is also important that they only see data related to their role in a computer system. This is called authorization. For the zoo, you will develop an authentication system that manages both authentication and authorization. You have been given a credentials file that contains credential...

I need help ASAP on this, this is due at midnight PST. This is the current code I have. How can I allow the user to quit. My counting while loop works fine, but I would like it to not keep outputting username if a file was successfully opened. This is what is required. Prompt You have assumed the role of managing the technology infrastructure at a zoo. You will develop a working program (either an authentication system or a...
In C++ Task 3: Use the stack and queue to simulate receiving and transforming data We are creating a system that will convert strings sent over a serial bus one character at a time. The conversion will be from big to little endian or from little to big endian. To simplify this, each character will be considered a word. Little endian will have the lowest address first. Big endian will have the biggest address first. For example (for this lab),...

C Programming - Please Help us! Implementing Load Balancing, the 3 Base Code files are at the bottom: Implementing Load Balancing Summary: In this homework, you will be implementing the main muti-threaded logic for doing batch based server load balancing using mutexes Background In this assignment you will write a batch-based load balancer. Consider a server which handles data proces- sing based on user requests. In general, a server has only a fixed set of hardware resources that it can...
