Protecting content on the web is something that most savvy users will have to do at one point or another. Whether the content is personal or professional, there comes a time when that content must only be seen by "authorized" eyes. The Apache web server ( that daemon that serves up your marvelous content ) allows a user to configure two files to facilitate this very purpose. Those files are.htaccess and .htpasswd.                 more...

The main vulnerability of Linux OS is that anyone can access the code of the operating system. And, if you are not savvy enough with the programming code like hackers are. You only need to search for the correct free Linux hacking tool and you will be able to get inside in no time.

 The other problem is that many of the drivers made for determined hardware. Let’s say, a printer is not created by people who have security in mind. This is especially important for a company who do not wish to find its intellectual property is stolen each time they send something to the printing room.

How to Harden your Linux Server

Share this post!

Vote this!

Is Linux secure? The question is much less useful, than 'Is Linux "securable"?' The answer to the latter is a definite yes. Being securable means that Linux can be made more secure (to whatever degree necessary) by applying a clearly defined sequence of steps that always produces the same result, and that can be automated and applied to systems that have been in operation for a long time. It would be ideal to be able to make securing systems understandable by regular system administrators who don’t have formal security training. However, the last requirement might be pushing it a bit, since security will likely always require expertise.

Linux can be made more secure by hardening the system.

There are two ways to use Linux on a Windows computer. You can either install the full Linux OS alongside Windows, or if you are just starting with Linux for the first time, the other easy option is that you run Linux virtually with making any change to your existing Windows setup.

The former option will offer the best performance because all your system resources will be available to Linux but the latter option is absolutely risk-free and therefore recommended for novice users. You’ll be able to test drive Linux but without changing a single file on your Windows computer.
