Whats is PFOS?
Usually I have been told to place employment with most recent at the top, yours appears to be backwards in that you want your present job at the top.
Are the project school projects or work projects? What were the results? If work projects how did they help, list them with the work. So if you picked a packet crafting tool what difference did it make. It feels like the projects should go with where they come from, school projects with coursework and work projects with employment list.
The skills list feels very laundry list for a fresh grad. This is ok for electronic resume when searching by keyword but for a paper resume or a resume you email to someone it looks like you listed every piece of software or technology you ever touched. I'd narrow it down to what is relevant to the job you are applying for, you will probably have multiple resumes if you are applying to a wide variety of jobs.
Also remember whoever sees this will spend only a short time looking it over and if the top of the resume doesn't grab them thats it so make sure whatever it is you want to emphasize is at the top. The resume is a tool to get an interview the interview is where you tell your whole story and background. You want it to sell yourself as being worth talking to.
Anyways I don't know if the rules differ for network admin stuff but there's a little feedback, hopefully it helps. Good luck!
