Linux is one of the favorite operating systems of those who work with computers and computer programming. It is a Unix-based OS. One of the drawback of this kind of operating system is that it is not designed with security paramount.
Though Linux is an extremely valuable OS for any sort of techie, it is very much a work in progress. One of the loopholes inherent in that process is the issue of DAC, or discretionary access control. DAC can defined as a method by which the access of certain objects is restricted based upon their origin. Want more? Click here. The DAC in the Linux kernel (a kernel is one of the main parts of an operating system that connects programs running on the OS to the data that they are processing) is simple and quite useful. Due to its simple design, however, it is not totally prepared for the modern IT environment. It also has a rather shoddy defense against malicious coding.
Some steps are being taken by the creators of Linux to shore up these issues with the kernel. However, one should bear in mind that it is a work in progress, and take the needed precautions to protect ones computer.
