You need to learn a computer programming language that is in-demand by corporations or organizations and that more marketable programming language is C# (.NET Framework and ASP.NET).

I would not recommend that you switch your career to Networking because that would require you to start your career from scratch. Starting from scratch means that you are guaranteed to earn less money anyway!

Also, your C/C++ background is more relevant to a computer programming career than an Information Security / Network Administration career.

Learning C# would be a better career move because you will be able to reuse your knowledge of programming and because your resume will look right to a hiring manager.

If you start from scratch in Networking, it would be hard to come by the required Networking experience but if you just learn a new programming language, it will be easier for you o transfer some of your current C/C++ programming skills.

Here are two (2) assignments for you:

Look into the number of C#/VB.NET/ASP.NET/.NET Framework Jobs versus the number of Network Admin / Information Security Jobs.
Look into the salary of C#/VB.NET/ASP.NET/.NET Framework Programmers versus the salary of Network Admin / Information Security Professionals.

I have little exposure (3 months work ex) to programming in Android iphone and Java.

I don’t make much money as an Programmer employee for past 5 years.

My Colleague stated that i need to swicth to Networking line and have to become Information security engineer to make more money.

This is new field. I am confused whether to stay in programming or switch to new field ( Network admin/information security).

Please help.
