1. The problem statement, all variables and given/known data:

I have a retake assignment to complete for my computer networks and OS class. This isn't really my area, had I known last year I could have swapped it for a different module I would have done so. I'm determined to get through it though.

Anyhow I digress. I am having trouble properly understanding the brief or where to begin it states:

"Monitoring a GNU/Linux system for changes:

For this referral assignment you are required to show how you might monitor important system directories in a GNU/Linux operating system for any changes in files or directories. Marks will be given as follows:

A) Provide an outline of which directories and files that you consider should be monitored for changes along with an indication of which changes you would monitor and how you would monitor them. ( up to 20%)

B) Provide a summary of available tools and utilities, both open source and commercial, that would help with this task. Your summary should include an indication of cost, complexity in
use and complexity in setup. ( up to 30%)

C) Develop a script or program that will implement at least some of the functionality required to support your analysis from (A). This script should keep a log of any changes found. The
script or program can be written in C, PERL, shell script or any other language that will execute on a GNU/Linux system. ( up to 50%)".


2. Relevant commands, code, scripts, algorithms:

N/A



3. The attempts at a solution (include all code and scripts):

I have a few theories and have been trying to do some research online but haven't found too much.

If anyone can help point me in the right direction it would be greatly appreciated.

4. School (University) and Course Number:

University of the West of England, Computing degree.
