Study Notes

Acquiring Evidence in a Computer Forensics Lab

A computer forensics lab is essential for evidence handling, acquisition, and analysis
There are similarities in basic requirements and guidelines for forensics labs
The American Society of Crime Laboratory Directors (ASCLD) provides guidelines and standards for forensics labs.
ASCLD/LAB is a separate nonprofit entity that accredits crime labs.
ASCLD/LAB was originally a committee within ASCLD and became a separate entity in 1984.
ASCLD/LAB certifies labs for federal, state, and local agencies, and some crime labs outside the United States.
ASCLD/LAB certification includes standards for computer forensics labs.
ASCLD/LAB promotes a code of ethics for lab staff and management.

Computer Forensics Laboratory Requirements

Private sector computer forensics laboratories have specific requirements.
Private sector labs require expertise in evidence acquisition, email preparation, inventory control, and web hosting.

Laboratory Requirements

Evidence lockers are crucial for secure storage of digital evidence.
Evidence lockers should meet specific security and environmental standards.
Digital evidence requires specific handling and storage procedures.

Digital Evidence

Digital evidence includes data stored electronically
Digital evidence is susceptible to alteration, deletion, or corruption
Proper procedures must be implemented to preserve the integrity and authenticity of
digital evidence.

UltraBlock SATA/IDE WRITE-BLOCKER

Write-blockers prevent accidental modification of evidence drives.
Write-blockers ensure that evidence is not altered or deleted.
They are a critical component for evidence acquisition.

SIM Card Reader

SIM card readers are used to extract data from mobile phones.
Information on SIM cards can include contacts, messages, and call logs.
These readers are essential for mobile device forensics.

USB-Powered Hard Drive

USB-powered hard drives provide portable storage for forensic data.
They are convenient for transferring data between labs and workstations.
USB-powered hard drives should be formatted using a forensic file system.

Evidence Bags

Evidence bags are used to package and seal digital evidence.
Evidence bags should be tamper-evident to ensure chain of custody.
They help to preserve the integrity of evidence during transport and storage.

A sign-in log helps to track access to the laboratory.
The sign-in log ensures accountability for evidence handling.
It helps to maintain the chain of custody for digital evidence.

UNIX & Linux Commands

UNIX and Linux commands are powerful tools for data extraction.
The dd utility copies data from a source to a destination.
The dd utility is an accepted file format for forensic imaging.
Global Regular Expressions Print (GREP) extracts data using pattern matching.
Extended Global Regular Expressions Print (EGREP) allows for use of operators not found
in basic GREP.
Fast Global Regular Expressions Print (FGREP) interprets characters literally and is faster than GREP.

Financial Fraud

Credit card numbering systems, including the Major Industry Identifier (MII), are used to identify various industry categories.
The Issuer Identification Number (IIN) refers to the first six digits of a credit card number.
Skimmers are electronic devices used to capture data from magnetic stripes on cards.
Skimmers are common tools used by identity thieves.
Skimmers are often examined in a computer forensics laboratory.
Skimmers are illegal in the United States but can be purchased in Canada or online.
Parasites are point-of-sale skimmers.
