INTRODUCTION TO CYBER FORENSICS What is Computer Forensics? Computer forensics, also referred to as computer forensic analysis, electronic discovery, electronic evidence discovery, digital discovery, data recovery, data discovery, computer analysis, and computer examination, is the examining computer media (hard disks, diskettes, tapes, etc.) for evidence. process of methodically A thorough analysis by a skilled examiner can result in the reconstruction of the activities of a computer user.

INTRODUCTION TO CYBER FORENSICS Use of Computer Forensics in law Enforcement:- If there is a computer on the premises of a crime scene, the chances are very good that there is valuable evidence on that computer. If the computer and its contents are examined by anyone other than a trained and experienced computer forensics specialist, the usefulness and credibility of that evidence will be tainted.

INTRODUCTION TO CYBER FORENSICS Choosing a Computer Forensics Specialist for a Criminal Case: When you require the services of a computer forensics specialist, don t be afraid to shop around. There are an increasing number of people who claim to be experts in the field. Look very carefully at the level of experience of the individuals involved. There is far more to proper computer forensic analysis than the ability to retrieve data, especially when a criminal case is involved. INTRODUCTION TO CYBER FORENSICS 5/8/2025 6

INTRODUCTION TO CYBER FORENSICS The bottom line is that you will be retaining the services of and individual who will likely be called to testify in court to explain what he or she did to the computer and its data. The court will want to know that individual s own level of training and experience, not the experience of his or her employer. INTRODUCTION TO CYBER FORENSICS 5/8/2025 7

INTRODUCTION TO CYBER FORENSICS Make sure you find someone who not only has the expertise and experience, but also the ability to stand up to the scrutiny and pressure of cross-examination. INTRODUCTION TO CYBER FORENSICS 5/8/2025 8

Computers can contain evidence in many types of human resources proceedings, including sexual harassment discrimination, and claims. forensics analysis is becoming suits, wrongful allegations termination of INTRODUCTION TO CYBER FORENSICS 5/8/2025 9

INTRODUCTION TO CYBER FORENSICS Evidence can be found in electronic mail systems, on network servers, and on individual employee s computers. However, due to the ease with which computer data can be manipulated, if the search and analysis is not performed by a trained computer forensics specialist, it could likely be thrown out of court.

INTRODUCTION TO CYBER FORENSICS Employer Safeguard Program:- As computers become more prevalent in businesses, employers must safeguard critical business information. An unfortunate concern today is the that data could be damaged, misappropriated by a discontented individual possibility destroyed, or INTRODUCTION TO CYBER FORENSICS 5/8/2025 11

INTRODUCTION TO CYBER FORENSICS Computer Forensics Services: A computer forensics professional does more than turn on a computer, make a directory listing, and search through files. INTRODUCTION TO CYBER FORENSICS 5/8/2025 12

INTRODUCTION TO CYBER FORENSICS For example, they should be able to perform the following services: Data seizure Data duplication and preservation Data recovery Document searches Media conversion Expert witness services Computer evidence service options Other miscellaneous services INTRODUCTION TO CYBER FORENSICS 5/8/2025 13

INTRODUCTION TO CYBER FORENSICS Data Seizure:- Federal rules of civil procedure let a party or their representative designated documents or data compilations that may contain evidence. inspect and copy INTRODUCTION TO CYBER FORENSICS 5/8/2025 14

INTRODUCTION TO CYBER FORENSICS Data Duplication and Preservation:- When one party must seize data from another, two concerns must be addressed: the data must not be altered in any way, and the seizure must not put an undue burden on the responding party. INTRODUCTION TO CYBER FORENSICS 5/8/2025 15

INTRODUCTION TO CYBER FORENSICS Data Recovery:- Sing proprietary tools, your computer forensics experts should be able to safely recover and analyze otherwise inaccessible evidence. The ability to recover lost evidence is made possible by the expert s advanced understanding of storage technologies. Ex: - when a user deletes an email, traces of that message may still exist on the storage device INTRODUCTION TO CYBER FORENSICS 5/8/2025 16

INTRODUCTION TO CYBER FORENSICS Document Searches:- Computer forensics experts should also be able to search over 200,000 electronic documents in seconds rather than hours. The speed and efficiency of these searches make the discovery process less complicated and less intrusive to all parties involved INTRODUCTION TO CYBER FORENSICS 5/8/2025 17

INTRODUCTION TO CYBER FORENSICS Media Conversion:- Some clients need to obtain and investigate computer data stored on old and unreadable devices. Expert Witness Services:- Computer forensics experts should be able to explain complex technical processes in an easy-to- understand fashion. This should help judges and juries comprehend how computer evidence is found, what it consists of, and how it is relevant to a specific situation INTRODUCTION TO CYBER FORENSICS 5/8/2025 18
