Abstract:
Information security has become a topic of growing interest not only in the Linux community, but in all areas of information technology. As the Internet develops, there is an increase of number of Linux servers, as well as Linux vulnerabilities that are made public. A Linux user has a wide variety of tools and techniques to protect against most types of intrusions. Unfortunately, there is no a secure system. Nevertheless, by improving network security measures as well as their proper implementation, the system has become a more difficult target to break its security.
