Chapter 19 RECOVERING DIGITAL EVIDENCE from LINUX SYSTEMS
Chapter 19 RECOVERING DIGITAL EVIDENCE FROM LINUX SYSTEMS Philip Craiger Abstract As Linux-kernel-based operating systems proliferate there will be an in evitable increase in Linux systems that law enforcement agents must process in criminal investigations. The skills and expertise required to recover evidence from Microsoft-Windows-based systems do not neces sarily translate to Linux systems. This paper discusses digital forensic procedures for recovering evidence from Linux systems. In particular, it presents methods for identifying and recovering deleted files from disk and volatile memory, identifying notable and Trojan files, finding hidden files, and finding files with renamed extensions. All the procedures are accomplished using Linux command line utilities and require no special or commercial tools. Keywords: Digital evidence, Linux system forensics !• Introduction Linux systems will be increasingly encountered at crime scenes as Linux increases in popularity, particularly as the OS of choice for servers. The skills and expertise required to recover evidence from a Microsoft- Windows-based system, however, do not necessarily translate to the same tasks on a Linux system. For instance, the Microsoft NTFS, FAT, and Linux EXT2/3 file systems work differently enough that under standing one tells httle about how the other functions. In this paper we demonstrate digital forensics procedures for Linux systems using Linux command line utilities. The ability to gather evidence from a running system is particularly important as evidence in RAM may be lost if a forensics first responder does not prioritize the collection of live evidence. The forensic procedures discussed include methods for identifying and recovering deleted files from RAM and magnetic media, identifying no- 234 ADVANCES IN DIGITAL FORENSICS tables files and Trojans, and finding hidden files and renamed files (files with renamed extensions. -

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. -
