Securing All Operating Systems
Now let's look at securing all operating systems. When we say securing all operating system we are talking about securing them in a corporate environment. Of course if you are using a Linux operating system at home or in a very small type of environment you only have one machine then you only are concerned of securing that specific operating system whether it's Linux Windows or whichever oppresses you system you're using. But if you are in a corporate environment where you are working with multiple servers and databases and applications then most likely you'll work in a tiered type of environment where you have some type of databases running on Windows or you're running the Web servers on the next you're running the Web logic the application piece on Oracle or Solaris. This type of mixed different on operating system environment is actually the corporate type of tiered environment.
So it is very important when you have this type of environment you need to secure all the operating system around it. So let's say if you have if you're supporting a retail company right and they have a web servers that is the front end of the company where people come in and make the purchase most of the time the web servers or they run on Linux. So they are running that's a front end and the back end is running on Solaris or Oracle which runs let's say Web logic application or maybe it's also Linux again depending on the corporate what they choose and then that the third tier would be the databases where all the information is stored. And sometimes people use Microsoft Eskew all Informix and Eskew all different type of rescue holds databases to anyway.
They all run a different operating system. If you change it around maybe the windows is the front end. Linux is the middle and the last one is Solaris. Anyway what I'm trying to say is any day any environment that you're working on that consist of multiple operating system you just not only have to secure that Pacific Linux system you have to secure every other operating system that it deals with as well because it's possible if its Windows is the one that is facing the Internet that is getting the virus or being attacked and it's being passed through Windows to Linux. So no matter how much secure your Linux is you're still getting the virus from windows. Similarly if you have Solaris server or Oracle server at the end and you have all the security patches and everything implemented on the last year which is right here and you have not done a good job on Windows on the next side then eventually yes you are compromising this Larry's operating system anyway to try to put everything in a nutshell make sure all the operating system in the environment are actually secured as well.
