Study Notes

Digital Forensic Concepts

Digital forensics supports legal cases, internal investigations, and incident response.
Techniques include data acquisition and analysis from various digital artifacts, such as drives and files.
Planning for forensic data gathering is essential to maintain a complete narrative of incidents.

Data Gathering and Documentation

Collecting evidence involves careful documentation of observations, conclusions, and supporting evidence.
Timelines, timestamps, file metadata, and event logs are critical in reconstructing the sequence of events.
Interviews with involved individuals can provide additional insights that aid investigations.

Data Breach Notification and Compliance

Data breach notification laws vary internationally and within the U.S., impacting response strategies.
Contracts often stipulate maximum notification times to customers regarding breaches, which can vary widely.
Organizations using cloud services need strategies for handling incidents without relying solely on direct forensic techniques.

Regulation and Jurisdiction

Venue specifies where legal cases are tried; contracts often favor the service provider's location.
Nexus denotes the connection between the case and the jurisdiction, influencing legal outcomes.

Forensic Tools and Techniques

Image analysis tools like Autopsy assist in identifying and analyzing files effectively. -- note aorellana: This is a software (autopsy Assist), it not very relevant for the exam.
Timelines within tools like Autopsy can show filesystem changes and help correlate events to incidents.
Accurate time settings are crucial; inaccuracies can lead to flawed forensic analysis.

Chain of Custody and Data Acquisition

Legal holds require preservation of relevant data; e-discovery must provide forensic data for legal proceedings.
Acquisitions must consider the order of volatility to prioritize what data to capture first.

Validation and Preservation

Hashing methods, such as MD5 and SHA1, validate the integrity of acquired data but have some vulnerabilities.
Following chain-of-custody protocols and using write blockers helps ensure data preservation is effective.

Forensic Reporting

Forensic reports should summarize findings, explain processes, and detail limitations impacting investigations.
Recommendations must be clear and supported by evidence, providing a comprehensive overview of the investigation.

Practical Application

To create an exact disk image on Linux, the command used should be dd, an essential tool for forensic acquisitions.
