Goal: Identifying and classifying malware Problem: For any single fingerprint, balance between over-fitting (type II error) and under- fitting (type I error) hard to achieve Approach: View binaries simultaneously from different structural perspectives and perform statistical analysis on these ‘structural fingerprints’ Different Perspectives Idea: Multiple perspectives may increase likelihood of correct identification and classification Structural Description Statistical static / Perspective Fingerprint dynamic?

  • N2N: a Layer Two Peer-To-Peer VPN

    N2N: a Layer Two Peer-To-Peer VPN

    N2N: A Layer Two Peer-to-Peer VPN Luca Deri1, Richard Andrews2 ntop.org, Pisa, Italy1 Symstream Technologies, Melbourne, Australia2 {deri, andrews}@ntop.org Abstract. The Internet was originally designed as a flat data network delivering a multitude of protocols and services between equal peers. Currently, after an explosive growth fostered by enormous and heterogeneous economic interests, it has become a constrained network severely enforcing client-server communication where addressing plans, packet routing, security policies and users’ reachability are almost entirely managed and limited by access providers. From the user’s perspective, the Internet is not an open transport system, but rather a telephony-like communication medium for content consumption. This paper describes the design and implementation of a new type of peer-to- peer virtual private network that can allow users to overcome some of these limitations. N2N users can create and manage their own secure and geographically distributed overlay network without the need for central administration, typical of most virtual private network systems. Keywords: Virtual private network, peer-to-peer, network overlay. 1. Motivation and Scope of Work Irony pervades many pages of history, and computing history is no exception. Once personal computing had won the market battle against mainframe-based computing, the commercial evolution of the Internet in the nineties stepped the computing world back to a substantially rigid client-server scheme. While it is true that the today’s Internet serves as a good transport system for supplying a plethora of data interchange services, virtually all of them are delivered by a client-server model, whether they are centralised or distributed, pay-per-use or virtually free [1].

  • Unix / Linux Processes Management

    Unix / Linux Processes Management

    UUNNIIXX // LLIINNUUXX -- PPRROOCCEESSSSEESS MMAANNAAGGEEMMEENNTT http://www.tutorialspoint.com/unix/unix-processes.htm Copyright © tutorialspoint.com Advertisements In this chapter, we will discuss in detail about process management in Unix. When you execute a program on your Unix system, the system creates a special environment for that program. This environment contains everything needed for the system to run the program as if no other program were running on the system. Whenever you issue a command in Unix, it creates, or starts, a new process. When you tried out the ls command to list the directory contents, you started a process. A process, in simple terms, is an instance of a running program. The operating system tracks processes through a five-digit ID number known as the pid or the process ID. Each process in the system has a unique pid. Pids eventually repeat because all the possible numbers are used up and the next pid rolls or starts over. At any point of time, no two processes with the same pid exist in the system because it is the pid that Unix uses to track each process. Starting a Process When you start a process (run a command), there are two ways you can run it − Foreground Processes Background Processes Foreground Processes By default, every process that you start runs in the foreground. It gets its input from the keyboard and sends its output to the screen. You can see this happen with the ls command. If you wish to list all the files in your current directory, you can use the following command − $ls ch*.doc This would display all the files, the names of which start with ch and end with .doc − ch01-1.doc ch010.doc ch02.doc ch03-2.doc ch04-1.doc ch040.doc ch05.doc ch06-2.doc ch01-2.doc ch02-1.doc The process runs in the foreground, the output is directed to my screen, and if the ls command wants any input (which it does not), it waits for it from the keyboard.

    Computer Viruses, in Order to Detect Them

    Behaviour-based Virus Analysis and Detection PhD Thesis Sulaiman Amro Al amro This thesis is submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy Software Technology Research Laboratory Faculty of Technology De Montfort University May 2013 DEDICATION To my beloved parents This thesis is dedicated to my Father who has been my supportive, motivated, inspired guide throughout my life, and who has spent every minute of his life teaching and guiding me and my brothers and sisters how to live and be successful. To my Mother for her support and endless love, daily prayers, and for her encouragement and everything she has sacrificed for us. To my Sisters and Brothers for their support, prayers and encouragements throughout my entire life. To my beloved Family, My Wife for her support and patience throughout my PhD, and my little boy Amro who has changed my life and relieves my tiredness and stress every single day. I | P a g e ABSTRACT Every day, the growing number of viruses causes major damage to computer systems, which many antivirus products have been developed to protect. Regrettably, existing antivirus products do not provide a full solution to the problems associated with viruses. One of the main reasons for this is that these products typically use signature-based detection, so that the rapid growth in the number of viruses means that many signatures have to be added to their signature databases each day. These signatures then have to be stored in the computer system, where they consume increasing memory space. Moreover, the large database will also affect the speed of searching for signatures, and, hence, affect the performance of the system.
