Cyber security, computer security or information technology security relates to the protection of computer systems. It deals with protecting the digital devices from theft or any kind of damages to the electronic data. Cyber security is becoming one of the major challenges in this contemporary world due to increasing reliance on smart devices that constitute the “Internet”, such as Bluetooth, Wi-Fi, and other internet wireless network standards. Hence, there comes a need for digital evidence collection in cyber security.
In today’s time, every person who is using the internet has to face the alarming cyber risks. The risk is considered to be at higher pace if there is no verified online security at your work station or at home. Life of the people is really not safe as they blindly rely on this internet world in different aspects such as shopping to email, messaging, social media, etc.
Digital Evidences are the kind of information in binary form which is mainly associated with e-crimes. During cybercrimes, it is the information that is derived from digital devices to get the pieces of evidence regarding the crime.
As computers and mobile phones are mainly used to commit crimes. One’s mobile phone files or system data can say a lot about the intention and workflows of that person. So, the law enforcement agencies started to do forensics investigation of the suspect’s digital devices to investigate the crime scene. Doing this will help them to implement digital evidence collection in cyber security. Furthermore, to carry out an in-depth investigation for the gathered crucial information, users can make the best use of computer forensics tool.
Digital forensics is the process to identify the digital evidence which is further used by the court of law. It is a science of finding the digital evidence within a process to analyse, inspect, identify and preserve digital evidence associated with electronic devices. It provides the best techniques and tools for the forensic team to resolve complicated digital cases.
Here are some of the major challenges that could be faced by the forensics examiner while collecting the evidence:
Process of digital forensics entails the following steps to gather or handle digital evidence:
Let’s discuss each one of them in detail for digital evidence collection in cyber security
4. Reporting and Documentation
In the digital forensic examination process, the most important competency for the one who conducts investigation is to gather and examine different types of evidence. Several types of evidence can be gathered out from the digital devices that can help the investigator to make wise decisions during the case.
First Rule: If the evidence is not related to the case, then it is not a relevant evidence. It must be appropriate to the investigation for the admissibility of court.
There are many types of evidence that are not admissible to court, but they are valuable for investigation to reach the conclusion. Some artefact are even not admissible in their own way, but they may be admissible in conjunction with other evidence.
Below mentioned are some advantages for Digital Evidence Collection in Cyber Security:
For digital evidence collection in cyber security, the investigator need to follow a proper procedure that helps to capture the perpetrator. By understanding this blog, it leads to efficiently recognize the crime scenario by following the different stages which is incorporated in digital forensics collection process. As a result, the gathered evidence is admissible in the court of law.
