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. -

Disk Utilities
STUDY MATERIALS ON HARDWARE INSTALLATION AND MAINTENANCE (As per the curriculum of fifth semester BSc Electronics of M. G. University) Compiled by Sam Kollannore U. Lecturer in Electronics M. E. S. College, Marampally DISK UTILITIES Disk Utilities are readymade softwares available in the market to help the computer user in managing the disk/drive and to help in the data recovery in case of some failure of the normal disk/drive operation. Example:- PCTOOLS and NORTON Utilities. These programs are useful to undelete accidentally deleted data, unformat accidentally formatted floppy and to recover from data corruption due to ill behavior of some software or some computer virus. New versions of Dos provide some of these facilities but these programs provide the same facilities with a lot more speed, accuracy and with additional options. PCTOOLS This package provide facility for:- 9 Data recovery – using the programs like DiskFix, FileFix, Unformat etc. 9 Unfragementing the disk – using programs like COMPRESS, DiskEdit etc. 9 Detecting and removing viruses – using the antivirus program CPAV (removes around 1400 viruses) 9 Searching, changing, adding, renaming, deleting and moving directories- using the Directory Maintenance program. 9 Searching files using FileFind 9 Providing information about your computer hardware, operating system and version, memory type and size and system speed – using the System Infomation (SI) program. DiskFix Command:- C:\PCTOOL\>DISKFIX Most useful program – can recover the data from very serious damages. DiskFix should be used regularly to detect and prevent potential problems. This program can do ¾ Repair most of the disk problem ¾ Thoroughly scan the disk surface for defects and damaged data, removing defective sectors and moving recoverable data to a safe location ¾ Recover lost cluster chains, including directories which CHKDSK cannot do ¾ Detect sectors going bad ¾ Low level format a disk that DOS cannot read or write properly without destroying any data. -
