Part III: Linux vs. Windows - Security
Sep 2 2008, 1:10 AM EDT
First, Linux was developed as a multi-user system. Therefore users are isolated from applications, files and directories that could damage the operating system. Each user has their own directory where system configuration and data files are stored. Another user cannot access or change anything within these directories without administrative access. This results in greater protection from system penetration from viruses, trojans, malware, etc because only the users files can be damaged while the overall system remains protected. Next, as mentioned above, Linux was designed as a modular operating system. This means that most parts of the operating system operate independently of one another. As a result, a vulnerability in one part of the operating system may not harm another application on that same system. This is because few applications depend on one another to operate effectively. Finally, unlike Windows which uses the RPC model, most Linux based distributions of programs have their network access turned off by default when they are installed on the users system. If the user wants the application to access the network, the user must manually activate this feature. The user is then required to clearly define the users and machines allowed to access the system. Even when Linux applications are installed with network access turned on by default (as some are), they are usually set up to ignore any requests from other machines on the network unless they are clearly defined by the user as previously mentioned. Additionally, Linux gives the user the ability to disable nearly all network-related RPC services and still have a fully functional machine. Do you find this valuable?
