Kernel Configuration Part XIII

Kernel Configuration - Part XIII

As you well know, Linux is simply the most robust operating system for
networking around. With its roots squarely in the network, Linux has managed to
stay ahead of the pack in virtually every respect related to networks. It should

come as little suprise, then, that the network section of your Linux kernel
configuration is dense with details and options.

I will say that I warned you on Monday - there are going to be some sections of
the kernel configuration series where I just can’t give you a stock
configuration that will work in every case. Networking is one of those areas.
You’re going to have to give some thought as to how your network is or will be
used and the level of security you want to provide (both internal and external).

Then, it’s a matter of finding the solutions to those options.

For security issues, I can recommend several good articles and HowTos:

The Linux Security Quickstart HowTo
  covers security on a high level, with a good discussion of kernel
configuration issues

Linux Network Security from Linux Planet
  a nice tutorial on network security

Network Security with /proc/sys/net/ipv4
  other approaches to network security

These should get you started. Tomorrow, we’ll cover telephony support in your
Linux kernel.
