Do you need mathematics in information security?

Study in the direction of "MIT" and very well go into the maths but wonder how much she need specialist information security? What mathematics is needed? Also, do you need physics how and what section?

@Lamar.Hickle23 it depends on what You mean by "information security". If it is a firewall to configure or implement a prepared SQL statements, the math here is not necessary, and the necessary documentation for the firewall/library.

And if you take in a broad sense, then:
  • Cryptography is non-trivial and mathematics: number theory, combinatorics, elliptic curves, information theory.
  • Cryptanalysis is mathematics: probability theory, stochastic processes, game theory.
  • Steganography - the same mathematics: coding theory, etc.
  • Quantum cryptography without quantum physics and tensor analysis to go there is nothing.
  • Analysis/prediction of threats - is also math: all sorts of neural networks, mathematical model, the same stochastic processes, and, God forgive me, God knows what else.

And Yes, underlying all of this is so all the unloved Matan. No sane Matane access to all these wonderful areas of mathematics is extremely limited and inconclusive.

No, if it does not work with the data.
You only need understanding of the sequence of steps in the transmission of information from sender to receiver and mastering tools to control access to the transmission medium.

Specialists in the protection of information from writers pieces of paper to the reverse engineers and developers of remedies to sale managers.
Subjectively, I can say that a straight butt lysmata and College physics a little where needed.
Offhand this profession: analyst, developer, architect.
Areas: cryptography, technical protection measures, software development.

But! little, just because a lot of areas, and already the above areas are very popular, not to mention the fact that I have a lot of things not mentioned.
And most importantly, the technical and exact Sciences is necessary not only to after graduation to lay a number on Taylor or be able to solve differe in the first place it is necessary for the development of analytical and rational methods of thinking. This is very useful in practice skill.

On the topic of what mathematics and physics are needed - in the technical universities it is the usual standard state program, if necessary for self-learning programme easy gugliada.

A specialist in information security writes you a former specialist in information security.
No. Not needed. Max basic knowledge - nothing more.
Let's have to live in reality. Without these College kriptografi, Mat and other heresies.
Us from school insisted that I needed at the Institute....
We cool..cheated.

Now on the skill.
Look at the teacher and their salary. They are good mathematicians, physicists.
Whatever - go into business? Do the conclusions. I did not - you are.
