The proposal to send a boot ID along with a message ID for each remote procedure call is to: a) Allow the client to tell if it received a duplicate response to a remote procedure call. b) Enable the client to identify whether the response came from an alternate backup server. c) Allow the server to distinguish among messages coming from different clients. d) Avoid having the server think a message is a duplicate when it is not.

A small insurance company has an online application system that allows its customers to interactwith the business (e.g., log claims). Backups of the customers’ details are done on a spreadsheetdocument stored on Google drive. However, anyone who has access to the Google drive link ofthe file can view and modify all the customer details. On the backup, the system administratordoes not have visibility of the modifications made on the file. By analysing the scenario above, use the security design principles to criticise theoperations of the small insurance company and propose any two simple controlsthat could influence a good security program.
An example of a host-based intrusion detection tool is the tripwire program. This is a file integrity checking tool that scans files and directories on the system on a regular basis and notifies the administrator of any changes. It uses a protected database of cryptographic checksums for each file checked and compares this value with that recomputed on each file as it is scanned. It must be configured with a list of files and directories to check and what changes, if any, are permissible to each. It can allow, for example, log files to have new entries appended, but not for existing entries to be changed. What are the advantages and disadvantages of using such a tool? Consider the problem of determining which files should only change rarely, which files may change more often and how, and which change frequently and hence cannot be checked. Consider the amount of work in both the configuration of the program and on the system administrator monitoring the responses generated.
Suppose the current denial state of a file in NFS is WRITE. Is it possible that another client can first successfully open that file and then request a write lock?
If you do not have execute access to the script file, the script may be run in one of two methods. What if you are unable to access the script's file?
A company has implemented a discretionary access control system for important documents and programs on a shared Linux server. Figure 1 shows the current implementation of the DAC system. It only applies to the directory /opt/company (you can ignore all files/directories that are not within this directory). The list of users is shown in the output from the firstls command; the members of each group is shown in the output of the tail command; the permissions are shown in the output of the second ls command. Assume the files are the objects, the subjects are the five users and there are four access rights: own, read, write and execute. Refer to Figure 4.2 and Table 2 in the textbook and complete the following subquestions I. Draw the Access Control Lists that illustrate the implementation on the Linux server; II. Draw the Capability Lists that illustrate the implementation on the Linux server; III. Build the Authorization Table that illustrate the implementation on the Linux server.
Which of the following best describes how operational logging is different from other logging types? A It facilitates service provisioning and financial decisions. B) It is a part of security logging. It concentrates on recording debugging logs. D) It records logs about user login, unauthorized access to resources, and so on.
Network Security: A process can be in one of three states: running,ready, and blocked. A job is a kind of processand can be in one of three states: foreground, background, and paused. What’s the similarity between the three process states and the three job states? Hint: It’s not a one-to-one mapping.
When attempting to access a resource, a user must supply a mutually agreed factor to the access control system. What is this phase of the process referred to? a. Impersonation b. Identification c. Authentication d. Authorisation e. Accounting
Securing a network from attacks means a network administrator is watching traffic and user activity. Change detection (CD) is a method used to track changes in your network. CD can detect files accessed during off hours to more complex algorithmic detections added to software applications that manage this process. This program is going to manage user login times and attempt to detect any change in a users typical login attempts. It will use an input file to store data and read the file using the csv.reader( ) method. The file will contain a list of login_names, followed by login_time separated by commas. Write a program that first reads in the name of an input file, reads the information stored in that file and determines if the user login has occurred at off hour times. The company employees work from 9 am to 5 pm so any other time would be an off hour login attempt. If the login attempt is made after hours, store the user name and login time in a dictionary with the user name as the…
Brute Attack on FTP server (KALI -LINUX) The file you downloaded contains the 100 most common passwords. Load the file in the Metasploit framework by setting the PASS_FILE variable. When you run the command, after some time, you will see a connection error and it says ‘scan complete’ but in reality, it is not. Why do you think that the first few scans went unsuccessful and then the connection error appears? Verify your answer using a log file generated at the victim’s machine. Furthermore, explain how you can circumvent this problem and show at least one working solution. Upload the log file generated at the victim's machine which shows the first few scans went unsuccessful and then the connection error appears. Also, include your answer and explain how you can avoid this problem.
