Part 1 Digital Forensics Module Jaap Van Ginkel Silvio Oertli
Part 1 Digital Forensics Module Jaap van Ginkel Silvio Oertli July 2016 Agenda • Part 1: Introduction – Definitions / Processes • Part 2: Theory in Practice – From planning to presentation • Part 3: Live Forensics – How to acquire a memory image – Investigate the image • Part 4: Advanced Topics – Tools – Where to go from here – And more 2 Disclaimer§ • A one or two-day course on forensics will not make you a forensics expert. – Professionals spend most of their working time performing forensic analysis and thus become an expert. • All we can offer is to shed some light on a quickly developing and broad field and a chance to look at some tools. • We will mostly cover Open Source Forensic Tools. 3 Introduction Forensics in History 4 Forensics – History 2000 BC 1200 BC 5 Introduction Definitions / Processes 6 Forensics – The Field digital forensics Computer Forensics Disk Forensics Mobil Forensics Memory Forensics Datenbase Forensics Live Forensics Network Forensics 7 Forensics - Definition • Digital Forensics [1]: – Digital forensics (sometimes known as digital forensic science) is a branch of forensic science encompassing the recovery and investigation of material found in digital devices, often in relation to computer crime. • Computer Forensics [2]: – Computer forensics (sometimes known as computer forensic science) is a branch of digital forensic science pertaining to legal evidence found in computers and digital storage media. The goal of computer forensics is to examine digital media in a forensically sound manner with the aim of identifying, preserving, recovering, analyzing and presenting facts and opinions about the information. 8 Forensics - Definitions • Network Forensics [3]: – Network forensics is a sub-branch of digital forensics relating to the monitoring and analysis of computer network traffic for the purposes of information gathering, legal evidence, or intrusion detection.[1] Unlike other areas of digital forensics, network investigations deal with volatile and dynamic information. -

Steganography- a Data Hiding Technique
International Journal of Computer Applications (0975 – 8887) Volume 9– No.7, November 2010 Steganography- A Data Hiding Technique Arvind Kumar Km. Pooja Assistant Professor Vankateshwara institute of computer Vidya College of engineering, Meerut, India Science and technology, Meerut, India ABSTRACT In steganography, the possible cover carriers are innocent looking Steganography is the art of hiding information and an effort to carriers (images, audio, video, text, or some other digitally conceal the existence of the embedded information. It serves as a representative code) which will hold the hidden information. A better way of securing message than cryptography which only message is the information hidden and may be plaintext, cipher text, conceals the content of the message not the existence of the message. images, or anything that can be embedded into a bit stream. Together Original message is being hidden within a carrier such that the the cover carrier and the embedded message create a stego-carrier. changes so occurred in the carrier are not observable. In this paper we Hiding information may require a stego key which is additional secret will discuss how digital images can be used as a carrier to hide information, such as a password, required for embedding the messages. This paper also analyses the performance of some of the information. For example, when a secret message is hidden within a steganography tools. Steganography is a useful tool that allows covert cover image, the resulting product is a stego-image. transmission of information over an over the communications A possible formula of the process may be represented as: cover channel. -

To casual observers, the tablet appeared blank. X Pirate legends tell of the practice of tattooing secret information, such as a map, on the head of someone, so that the hair would conceal it. 5 SteganographySteganography X Both Axis and Allied spies during World War II used such measures as invisible inks -- using milk, fruit juice or urine which darken when heated. X Invisible Ink is also a form of steganography 6 SteganographySteganography X The U.S. government is concerned about the use of Steganography. X Common uses in include the disguising of corporate espionage. X It’s possible that terrorist cells may use it to secretly communicate information X It’s also a very good Anti-forensics mechanism to mitigate the effectiveness of a forensics investigation 7 SteganographySteganography Terror groups hide behind Web encryption By Jack Kelley, USA TODAY AP WASHINGTON — Hidden in the X-rated pictures on several pornographic Web sites and the posted comments on sports chat rooms may lie the encrypted blueprints of the next terrorist attack against the United States or its allies. -

12/04/13 1. Einleitung 1 1. Einleitung − Was ist Systemadministration? ============================================= 12/04/13 1. Einleitung 2 System Administration: It’s a dirty job, but someone said I had to do it. Aufgaben eines Sysadmin gestern und heute: Früher Heute − Einrichten von neuen Nutzern Auch heute gibt es neue User per Hand mit Scripte, Oberflächen automatisiert − Druckermanagment Tonerpatrone Wechseln, Druckerjobs canceln, Drucker reaktivieren, Nutzer beruhigen, Das ist immer noch so. "Der Drucker druckt nicht, ich habe nichts gemacht." − Fragen beantworten: "Wie kann ich ....?" Die Nutzer lesen immer Das "Dialog−Manual" noch keine Manuals. − Prozesse killen Auch heute sollen Prozesse noch endlos laufen. 12/04/13 1. Einleitung 3 Früher Heute − Prozesse/Daemone nach Möglich, aber es gibt Absturz neu starten auch Überwachungstools − Tastaturen aktivieren kommt seltener vor − Backups veranlassen Die Datenmengen sind (zeitzyklisch, häufig) nur viel größer. − Restore von Files Auch heute löschen Nutzer ihre Files unabsichtlich. − "Mein Rechner macht nichts mehr!!!!" Passiert seltener, da die Monitoring/Tracing Rechner schneller sind und mehr Prozessoren haben, gibt es dieses Problem nicht so oft. − Rebooting von Systemen Alle zwei bis drei Jahre kommt bei Fehlern so etwas noch vor. − Speicherplatz auf Platten schaffen Jeder erfüllte Wunsch erzeugt Hilferuf: "Ich kann nichts mehr viele neue kleine Wünsche speichern!!!!" − Sicherheitslöcher finden und Schlimmer als je zuvor, beseitigen, Einbrecher suchen dank Internet und verfolgen 12/04/13 1. Einleitung 4 Früher Heute − Passwörter prüfen Nicht mehr nötig dank neuer Technologien − Programme installieren Es soll auch heute noch neue Programme geben. Einheitliche Verfahren erleichtern aber die Arbeit. − Betriebssystemupdates Vereinfacht. − Konfiguration des Rechnernetzes ja − Installieren neuer Rechner. -
