Hence, the answer to how to collect digital evidence in cyber forensics is not so simple since it requires focus, attention, dedication, honesty, strictness, and extreme professionalism towards collecting and analyzing the digital evidence. 

What Does Digital Evidence Mean?

So, in short, the digital evidence is basically a proof that contributes to proving someone guilty or not guilty for any particular event. These sources of digital evidence are multiple, including emails, logs, mobiles, cloud storage, and more. In addition to this, the biggest difference between the physical and electronic evidence is that the digital ones can be easily corrupted, sorted, deleted, and altered without leaving any footprints. 

Therefore, to maintain the authenticity and originality of the evidence, the investigators need to follow a strict chain of practices where they safely collect the data and keep it in their original form without any alteration. Over and above that, for investigators or law enforcement bodies, the digital evidences are the key elements that helps in solving any case, including property theft, cybercrime, etc., more easily and transparently. 

How to Collect Digital Evidence in Cyber Forensics?

The entire process to collect evidence demands a lot of precision and attention. Thus, the prominent methods to do this like a professional digital forensics investigator include:

1. Disk Imaging: This is basically creating an exact copy of the storage devices or the data found from the evidence. With this, the investigator makes sure that the original evidence is unaltered and the investigation is being practiced on the copied data. 
2. Email Header Analysis: If the investigators do the email header analysis, they can have access to the location from which the email is drafted, have a look at phishing attempts, and even get other hidden data such as device name, data, time, device model, and more. 
3. Examining the Log File: This is one of the most crucial steps or methods of digital forensics in which the investigator checks the system as well as application activities. It includes login attempts, the number of times data is being transferred, configuration changes, and so on.
4. Network Analyses: This method helps in identifying suspicious activities such as unauthorized communication, malware transmissions, and more. It is more like real-time monitoring of the network. 
5. Mobile Device Forensics: Last but not least, mobiles have the maximum data, whether it's the chats, phone call logs, location data, browsing history, applications, and more. Experts deeply analyse each one of them and make sure to retrieve all the hidden or connected data. 

What Are The Common Challenges In Collecting Digital Evidence?

Collecting digital evidence for forensic investigation might look simple and quick, but it is full of challenges. Some of the most common hurdles that an investigator encounters while collecting digital evidence are as follows:

• The investigation slows down due to large encrypted and password-protected files. 
• The case demands high-tech tools to recover the deleted and overwritten data. 
• Plus, the criminal complicates the process by erasing digital footprints like a professional.
• Digital forensic investigators must constantly learn and adopt advanced methods to ensure they don't miss any evidence.

Why Do You Need Professional Help to Collect Evidence for Digital Forensics?
