I don't want to use linux for a firewall. &nbsp;In fact I already have a firewall. &nbsp;What I need is information on securing the Linux OS. &nbsp;If I use my linux box as a web server without changing the default settings I'm sure I would be open to numerous types of attacks (ie DoS). &nbsp;The same would go if I used it as a DB server and so on. &nbsp;I was looking for information on how to secure linux depending on it's role. &nbsp;The steps to secure a web server would not neccesarily be the same steps to secure a DB server.<br />

Thanks,<br />

Hello,<br />
<br />
I just setup Redhat linux 6.1 as a proxy server using squid. &nbsp;I seriuosly doubt that linux is a secure nos out of the box so my question is what steps do I need to take in order to make linux secure from outside (or inside) attacks. &nbsp;Not just as a proxy server but as a web/db/file server. &nbsp;I haven't seen any real step by step procedure for securing linux with respect to it's role. &nbsp;I'm not looking for a bunch of links or documents that discuss linux security but offer no real information.<br />

Linux Security

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).

Linux Distributions

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
