Dealing with Process Overload Attacks in UNIX

ABTRACT

A process overload attack is an attack on a shared computer system in which a user repeatedly forks new processes and hence makes the system unusable for others. The specific problem we address is seen in an academic environment where student programs create unintentional process overload attacks in UNIX systems by careless coding. Instead of rebooting the system or manually examining and killing the processes, our approach to dealing with these attacks was to build a process load monitoring tool to detect and kill these processes automatically. This paper focuses on what we learned about the behaviors of different fork bombs, how we classified them based on their self-replicating capabilities, and our experience with detecting, killing and cleaning these unwanted processes.     

Justifications,Strategies, and Critical Success Factors in Successful ITIL Implementations in U.S. and Australian Companies: An Exploratory Study

Abstract

A growing number of organizations are implementing the ITIL (IT Infrastructure Library) “best practice” framework in an attempt to improve their IT service management processes. However, not all ITIL implementations are successful and some companies have been disappointed with the outcomes. This exploratory research reports on four case studies of “successful” implementations of IT service management using the process-based ITIL V2 framework. Two companies are located in the U.S. and two in Australia. The cases demonstrate a mix of implementation justifications and strategies. Critical success factors (CSFs) suggested in the literature are compared against those attributed to these successful ITIL implementations. Some CSFs, including executive management support, interdepartmental communication and collaboration, use of consultants, training and careful software selection are confirmed. Three new CSFs are identified: creating an ITIL-friendly culture, process as a priority, and customer-focused metrics. Practitioner guidelines, to assist IT managers, who are contemplating adopting ITIL for process improvement and organisational transformation, are also provided together with some challenges encountered and their associated resolutions.     

Application Development Productivity Tools: A Survey Of Importance and Popularity

Application development productivity is becoming an increasingly important issue in the MIS department. Unfortunately, dramatic improvements in hardware performance have not been matched with corresponding advances in software development, even though there have been significant investments in productivity tools. This article identifies a range of productivity tools and presents results from a survey of MIS managers that reveals which specific tools are being used and their relative importance to software development productivity.
