Types of Cyber Forensics 

Cyber forensics covers several areas, each focusing on a different type of digital evidence collected from various sources. These fields help investigators analyse and interpret the gathered data. To fully understand what is cyber forensics, one can explore these specialised areas, each addressing a unique aspect of digital investigation. Some of the major categories of computer forensics are listed below:

• Disk Forensics: It examines storage devices such as hard drives and USB sticks. It helps recover deleted files and restore lost information.
• Network Forensics: It inspects data traffic and network logs. This process aids in recording digital interactions during incidents.
• Mobile Device Forensics: It focuses on portable devices such as smartphones and tablets. It recovers messages, contacts and application data.
• Memory Forensics: It investigates temporary data stored in a computer’s memory. The method captures details of running applications and system activities.
• Malware Forensics: It studies harmful software. It clarifies how malicious code operates and its effects on systems.
• Cloud Forensics: It examines information stored on remote servers. This approach addresses challenges in retrieving evidence from online platforms.

Importance of Cyber Forensics

Cyber forensics plays an important role in securing digital evidence for investigations. It assists experts in preserving electronic data to ensure that details remain unchanged for legal inquiries. As we learn what is cyber forensics, we understand that this discipline supports criminal investigations and organisational security by providing factual records. Additionally, it contributes to identifying system weaknesses to prevent it from future incidents.

Some of the benefits of cyber forensics are discussed below:

1. Evidence Integrity

Cyber forensics makes sure that digital records are maintained in their original state. This careful handling allows investigators to rely on authentic data during investigations and court proceedings.

2. Support in Legal Processes

Reliable electronic evidence plays a crucial part in legal cases. They help clarify events and lead to fair judicial decisions.

3. Incident Reconstruction

Detailed analysis of digital data helps rebuild the timelines of events. This method assists authorities in understanding how a cyber incident happened and determining its causes.

4. Enhanced Security Measures

By identifying how breaches occur, cyber forensics guides organisations in strengthening their security. While understanding what is cyber forensics, we learn that it helps fix weaknesses and improve defences against future attacks.

5. Organisational Accountability

Keeping precise records means that people are held responsible for their actions. This transparency encourages honest behaviour and helps resolve disputes.

6. Risk Mitigation

Finding weak spots in systems early on can stop problems before they occur. Organisations can then take steps to lower the risk of future breaches.

Cyber Forensics Process

Cyber forensic investigations follow a structured series of steps to properly manage digital evidence. Each phase is designed to maintain the integrity of information and build a clear account of events. To understand what is cyber forensics, one must know that every stage plays an important role in finding digital evidence. These procedures help experts collect and examine data in a methodical manner. The following pointers explain the main processes involved in cyber forensic investigations:

• Identification: Investigators start by finding digital items that might contain important evidence. They carefully inspect systems and devices to spot data that can help explain what happened.
• Preservation: After identifying potential evidence, it is secured to keep it unchanged. Special methods are used to protect the data from any modifications during further investigation.
• Collection: Next, experts gather the identified digital evidence in an organised manner. They document and store each piece of information to ensure accuracy and preserve its original state.
• Analysis: The collected data is then examined in detail to uncover important insights. This step helps rebuild the timeline of events and clarifies the circumstances surrounding the incident.
• Documentation and Reporting: Finally, the findings are recorded and compiled into clear reports. This thorough documentation provides a reliable record for legal cases and explains the outcomes of the investigation.

Techniques of Cyber Forensics

Digital investigations rely on several techniques to reveal hidden clues within electronic devices. These methods help experts recover lost or concealed data and reconstruct events with clarity. Each technique focuses on a specific aspect of digital data analysis and follows unique procedures to preserve evidence. While understanding what is cyber forensics, it is important to be aware of the following techniques:

• Forensic Imaging: This technique creates an exact copy of digital media. It ensures that every bit of data is preserved so that analysis can be carried out without altering the original evidence.
• Data Carving: This method retrieves files by scanning raw data, even when file system details are missing. It identifies and recovers deleted or hidden files based on known file patterns.
• Hash Analysis: This process employs mathematical functions to generate unique fingerprints for files. It verifies that the data remains unchanged by comparing these fingerprints with original values.
• Timeline Analysis: This technique reconstructs events by organising digital records in sequence. It helps investigators understand the order of activities and build a clear picture of incidents.
• Log File Examination: This method inspects logs from systems and applications to track user actions. It uncovers important details by reviewing recorded events and detecting irregularities.
• Memory Analysis: This technique examines the temporary data stored in a computer’s memory. It reveals information about active processes that may not be captured on permanent storage.
• Network Traffic Analysis: This method monitors data flows across networks. It identifies unusual activity by analysing patterns and detecting signs of cyber incidents.
