On the one hand, you have the recent Windows source code leak. On the other hand you have a series of flaws discovered in the Linux kernel over the past few months. Many fear what may come from the Windows source code leak once the bad guys get done picking it apart and finding the holes. The argument is that if the code had been open source any such vulnerabilities...Read More |
