I am thinking of Entering in Network Security Field.
It can be securing windows network , linux network
But exactly don't ave the full picture how does that area is divided I only have the vague idea.
i want some position where company call me to check their system to see if its secure. Or govt can hire to secure network from external access.
Any thing like that
Can anyone give me some idea how can i start.
Is there any scope in that area. How its growing in future.
Are there any certification which ican do to start with
