Digital-Forensic

As society increases reliance on computer systems and cloud computing, digital forensic becomes a crucial aspect of law enforcement agencies and businesses. Digital forensic is the most intricate step of the cybercrime investigation process, and often yields the strongest evidence in terms of prosecutable cases. Digital forensic is the scientific acquisition, analysis, and preservation of data contained in electronic media whose information can be used as evidence in a court of law.

The goal of the process is to preserve any evidence in its most original form while performing a structured investigation by collecting, identifying, and validating the digital information to reconstruct past events. All processes utilize sound forensic techniques to ensure the findings are admissible in court.

Digital Forensic Investigation Process:
Digital forensic investigations commonly consist of four stages:

  • Seizure: Prior to actual examination digital media is seized by the digital forensic examiner and the chain of custody maintained.
  • Acquisition: Once devices are seized, a forensic duplicate of the data is created using a hard drive duplicator or software imaging tool. Then the original drive is stored securely to prevent tampering. The acquired image is verified with SHA-1 or MD5 hash functions and will be verified again throughout analysis to verify that the evidence is still in its original state.
  • Analysis: After acquisition, the forensic examiner recovers evidence using a number of methods (and tools), often beginning with the recovery of deleted information. The type of data analysed are email, chat logs, images, internet history and documents.
  • Reporting: Once the investigation is complete, the information is collated into a report that is accessible to non-technical individuals. It may include audit information or other meta-documentation.

Legal Considerations of Digital forensic:
The examination of digital media is covered by national and international legislation. In general, laws dealing with digital evidence are concerned with:

  • Integrity: Ensuring the act of seizing and acquiring digital media does not modify the evidence (either the original or the copy).
  • Authenticity: The ability to confirm the integrity of information. The chain of custody from crime scene through analysis and ultimately to the court, in the form of an audit trail, is an important part of establishing the authenticity of evidence.

Computer Forensic Investigation

Computer forensic investigation and analysis is a techniques to gather and preserve evidence from a particular computing device in a way that is suitable for presentation in a court of law. The goal of computer forensic investigation is to perform a structured investigation and maintain a documented chain of evidence to find out exactly what happened on a computing device and who was responsible for it.

Why is computer forensic important?

Computer forensic helps ensure the integrity of digital evidence presented in court cases. As computers and other data-collecting devices are used more frequently in every aspect of life, digital evidence and the forensic process used to collect, preserve and investigate it has become more important in solving crimes and other legal issues.

Computer Forensic Investigation starts with the collection of information in a way that maintains its integrity. Investigators then analyse the data or system to determine if it was changed, how it was changed and who made the changes. The use of computer forensic isn't always tied to a crime. The forensic process is also used as part of data recovery processes to gather data from a crashed server, failed drive, reformatted operating system (OS) or other situations where a system has unexpectedly stopped working.

Types of computer forensic

There are various types of computer forensic examinations. Each deals with a specific aspect of information technology. Some of the main types include the following:

  • Database forensic: The examination of information contained in databases, both data and related metadata.
  • Email forensic: The recovery and analysis of emails and other information contained in email platforms, such as schedules and contacts.
  • Malware forensic: Sifting through code to identify possible malicious programs and analysing their payload. Such programs may include Trojan horses, ransomware or various viruses.
  • Memory forensic: Collecting information stored in a computer's random access memory (RAM) and cache.
  • Network forensic: Looking for evidence by monitoring network traffic, using tools such as a firewall or intrusion detection system.
  • Mobile forensic: Mobile forensic is a branch of digital forensic related to the recovery of digital evidence from mobile devices in such a way that the evidence is preserved in a forensically sound condition.
    The growing need for mobile device forensic is driven by:
    • Use of mobile phones to store and transmit personal and corporate information
    • Use of mobile phones in online transactions
How does computer forensic work?

Data collection:

  • Electronically stored information must be collected in a way that maintains its integrity. This often involves physically isolating the device under investigation to ensure it cannot be accidentally contaminated or tampered with.
  • Examiners make a digital copy, also called a forensic image, of the device's storage media, and then they lock the original device in a safe facility to maintain its pristine condition. The investigation is conducted on the digital copy.
Analysis:
  • Investigators analyse digital copies of storage media in a sterile environment to gather the information for a case.
  • Various tools are used to assist in this process, including Basis Technology's Autopsy for hard drive investigations.
Presentation:
  • The forensic investigators present their findings in a legal proceeding, where a court uses them to help determine the result of a lawsuit.
  • In a data recovery situation, forensic investigators present what they were able to recover from a compromised system.

E-Mail Forensic

Emails play an important role in business communications.

The negative side of emails is that criminals may leak important information about their company. Hence, the role of emails in digital forensic has been increased in recent years. E-Mails are one of the most crucial evidentiary factors in almost every case litigated nowadays. Many a times E-Mails are either intentionally erased or accidently deleted by users. In digital forensic, emails are considered as crucial evidences and Email Header Analysis has become important to collect evidence during forensic process. These E-Mails can be recovered from their HDDs and source files stored on the system or E-Mail servers.

Incident Response

An intrusion or attack can be frustrating or even mentally and emotionally demanding. One can certainly be better prepared and equipped to handle such a situation judiciously. Incident Response comprises of a set of instructions for managing cyber-attack or any form of security breach. Incident Response is an organized approach to addressing and managing the aftermath of a security breach or attack (also known as, ‘incident’). The goal is to handle the situation in a way that limits damage and reduces recovery time and costs. An incident response plan includes a policy that defines what constitutes an incident and provides a step-by- step process that should be followed when such an incident occurs. Incident response (IR) plans are designed to test your company’s ability to respond to a security incident.

Data Leak Analysis

Every enterprise possesses sensitive data and securing the same is of paramount importance. Data Leak is an unauthorized transfer of classified information from a computer or datacentre to the outside world. Data leakage can be accomplished by either mentally remembering what was seen, by physical removal of tapes, disks and reports or by rather subtle means such as data hiding (see steganography). Sensitive data of companies and organizations include Intellectual Property (IP), financial information, patient information, personal credit-card data, and other valuable data depending on the business and the industry. Data leakage imposes a serious concern today for most organizations, considering the sheer number of such incidents in the recent past and cost borne by victims which continues to increase.
