AI Thread Summary
Interest in internet and network security is growing, particularly as a subset of computer security. For those with a math background and limited programming experience, foundational programming courses, starting with Python, are essential. It's recommended to pursue courses that align with specific interests, such as cryptography, which is a key area for applying mathematical skills in security. The Security+ certification is also valuable for entering the field, though it requires recertification every three years. Engaging with academic advisors can help identify relevant courses, particularly those related to cryptography, such as Formal Languages and Automata and Computational Complexity. Exploring career paths, especially with organizations like the NSA, can provide further direction in this field.

Lately I have been getting interested in internet/network security (an area of study which I am guessing is a subset of computer security). I use to do a little bit of programming a long time ago, but since it has been so long, let's assume that I have no programming experience. I am a math major at a university that seems to have a good selection of computer science courses that I can take. The only thing is, as I don't know much about computers, I don't really know which courses I should take. I do know that I will take some programming courses (they start you off programming in Python). I was hoping you guys could tell me which courses which be best for me to take. Or if isn't too much trouble, take a look at the list of courses and recommend some:

I would appreciate all help. Thanks!

If you're going to get into network security, you'll eventually need to know most of what's in the Security+ certification exam. The exam doesn't require any coding skills but it is something that you should eventually take if you want to get into the field. The certification does have a time limit though. It is only good for three years and then you have to be re-certified.

Adding to what Borg suggested, I think it's also helpful to know what your goal is. Do you want to implement existing solutions, or develop new solutions? The former does not usually require any university (programming) courses, while the latter might.

I am mostly interested in the encryption side of security...I am looking for an area where I can apply my math skills. Think of the type of mathematician/computer scientist that the NSA would employ.

Ahh, cryptography/cryptology it is then. :) The NSA does hire BS/BA Math majors for the field in which you're interested. Have you checked their site for any information regarding career paths?

As far as programming goes, you should meet with an advisor and ask about any CS courses related to cryptography/cryptology. Unless there is someone here with intimate knowledge of the CS program at your institution, we can only give some general advice.

Here's a relevant link to a wiki that might give you some ideas for the discussion with an advisor:

https://en.wikipedia.org/wiki/Cryptography#Modern_cryptography

Edit: Taking a quick look through the link you posted, I do not see any courses directly related to Cryptography. However, here are two I found that have some relevance:

CSC448H1 Formal Languages and Automata(24L/12T)
CSC463H1 Computational Complexity and Computability(24L/12P)

Again, you'll want to talk to an advisor to make sure, but the topics covered in the above courses are related to cryptography.

Hey, I am Andreas from Germany. I am currently 35 years old and I want to relearn math and physics. This is not one of these regular questions when it comes to this matter. So... I am very realistic about it. I know that there are severe contraints when it comes to selfstudy compared to a regular school and/or university (structure, peers, teachers, learning groups, tests, access to papers and so on) . I will never get a job in this field and I will never be taken serious by "real"...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation. This article's date received is 2022-11-15...
