The Flux Research Group works in software systems . Our interests and work cover many areas, including both local and distributed operating systems, networking, component-based systems, programming and non-traditional languages, compilers, information and resource security, and even a pinch of software engineering and formal methods. All of our publications and some presentations are available. Additionally, we try to produce and distribute usable versions of the developed software .
Securing your Linux server is important to protect your data, intellectual property, and time, from the hands of crackers (hackers). The system administrator is responsible for security Linux box.
