Windows vs Linux System Calls

Windows has grown so complicated that it is harder to secure. The images below are a complete map of the system calls that occur when a web server serves up a single page of HTML with a single picture. The same page and picture. The more system calls, the greater potential for vulnerability, the more effort needed to create secure applications.

The first picture is of the system calls that occur on a Linux server running Apache.


This second image is of a Windows Server running IIS.

  2. This is really a good news for people in UK who use the telecom operator Orange. There are a lot of access numbers that you can use to make free free business calls to almost anywhere in the world. All you need to do it to send an email to get your personalized access number.
