Shell Programming and Scripting

Hi,

I am about to take up task of shell scripting in Network Security. Just started on job. But everything looks new NIS etc..

I tried googling to find systematic explanation of network security terms and how to script for that. But was unable to find. Could anyone of you please direct me to proper website to learn about this stuff.

Thanks

NIS is not secure, a "ypcat passwd" will give all the users (no problem with that) but also the the users' encrypted passwords which can then be cracked...

Network security as a whole is an enormous subject, one site worth looking at concerning IT security is at:
Center for Internet Security - Standards

I hope others may point you at more network security focused sites.

You may want to consider getting some training and certification, e.g.: http://www.isc2.org/credentials/default.aspx
