You are investigating a possible intellectual property theft by a new employee of Superior…

Task 1: Recovering scrambled bits (5%) (5 marks)

For this task I will upload a text file with scrambled bits on the suject interact2 site closer to the assignment due date. You will be required to restore the scrambled bits to their original order and copy the plain text in your assignment.

Deliverable: Describe the process used in restoring the scrambled bits and insert plain text in the assignment.

Task 2: Digital Forensics Report (20%) (20 marks)

In this major task you are asked to prepare a digital forensic report for the following scenario after carefully reading the scenario and looking at textbook figures as referred below:
You are investigating a possible intellectual property theft by a new employee of Superior Bicycles, Inc. This employee, Tom Johnson, is the cousin of Jim Shu, an employee who had been terminated. Bob Aspen is an external contractor and investor who gets a strange e-mail from Terry Sadler about Jim Shu’s new project (shown in Figure 8-5 of the textbook on p. 350). Bob forwards the e-mail to Chris Robinson (the president of Superior Bicycles) to inquire about any special projects that might need capital investments. Chris forwards the e-mail to the general counsel, Ralph Benson, asking him to look into it. He also forwards it to Bob Swartz, asking him to have IT look for any e-mails with attachments. After a little investigation, Bob Swartz forwards an e-mail IT found to Chris Robinson (shown in Figure 8-6 of the textbook on p. 350).

Chris also found a USB drive on the desk Tom Johnson was assigned to. Your task is to search for and determine whether the drive contains any proprietary Superior Bicycles, Inc. data in the form of any digital photograph as an evidence. In particular, you may look for graphic files such as JPEG on the USB drive hidden with different format. Note for the USB drive image, you need to download the “C08InChp.exe” file from the download section of Chapter 8 on the student companion site of the textbook (Nelson, Phillips, & Steuart, 6/e, 2019).

Your task is to search all possible places data might be hidden (e-mails and USB drive) and recover and present any digital evidence in the report.

Deliverable: For this forensic examination, you need to provide a report of 1800-2000 words (approximately 5 A4 pages) in the format described in presentation section below.

In this assignment, you are expected to design and implement a simple file system (SFS) that can be

mounted by the user under a directory in the user’s machine. You need to demonstrate a file system

working in Linux. It may work with some modifications in other Unix-like operating systems (e.g., OS

X). To simplify the assignment, SFS introduces many limitations such as restricted filename lengths, no

user concept, no protection among files, no support for concurrent access, etc. This is a design assignment.

Therefore, several aspects of the SFS are left undefined. It is your responsibility to make valid assumptions

and document them. No matter what assumptions you make, your implementation should work with the

testers and also it should be mountable through FUSE to get full marks.

Here is a list of restrictions we propose for SFS. You could add more provided you keep the SFS

functionally compatible with the testers and FUSE. You need to document all the simplifying assumptions

you make.

• Limited length filenames (select an upper limit such as 16)

• Limited length file extensions (could be set to 3 – following the common extension length)

• No subdirectories (only a single root directory – this is a severe restriction – relaxing this would

enable your file system to run many applications)

• Your file system is implemented over an emulated disk system, which is provided to you.

Here is a schematic that illustrates the overall concept of SFS in direct mode. You need to implement the

yellow (orange) component. The other two components (tester and disk) are given to you.

Figure 1: SFS in direct mode.

The problem with the direct mode is that SFS is only usable by your program. You may not be happy about

it! Why not use SFS to store data created by an editor like vi? The mountable version of SFS addresses

this problem. It allows you to store anything and treat SFS like an extension of the OS. The magic is

performed by FUSE – file systems in user space. The concept of FUSE is similar to the concept we saw in

micro kernel OSes. I said it is similar to micro-kernel OS (it is actually not).

    Given two times when seen on a digital clock, count the number of moments between these two times… 1 answer below »

    Given two times when seen on a digital clock, count the number of moments between these two times (both start and end time included) when the time was a palindrome.

    A digital clock shows time in the format HH:MM:SS (hours:minutes:seconds).

    For example, 2:40:38 pm is represented as 14:40:38.

    Input

    The first line contains q queries.
    This is followed by q lines each containing two time strings, t1 and t2, which are 6 digit integers that represent times shown by a digital clock. It is ensured that t1 and t2 are valid times.

    Output

    • Each output on a new line.

    Constraints

    • 1 = q = 105
    • t1 and t2 are of the form HH:MM:SS
    • t1 occurs on or before t2

    Example

    Input: 4 00:00:01 00:00:01 09:09:09 13:34:57 11:11:11 11:11:11 02:38:15 03:01:16
    Output: 0 22 1 3

    Explanation

    Case 1: Only 1 moment is considered in this case, i.e., 00:00:01. We can clearly see that 00:00:01 is not a palindromic string.
    Case 4: Between 02:38:15 and 03:01:16, there are 3 moments that are palindromic strings. They are 02:44:20, 02:55:20 and 03:00:30.

    Note that the time as seen on a digital clock should appear as a palindrome. 1 is a palindrome, but 00:00:01 on a digital clock is not.
