Let Us Explore Challenges Faced By Forensic Investigators
From the past few years, technology has evolved at a much faster pace than expected. With the advancement in technology, there is a great increase in the frauds associated with technology. Nowadays digital forensic investigators facing more complex challenges in digital forensic evidence collection. However, there are numerous investigation techniques and tools available using which the forensic examiner can investigate cases in a better way and carve evidence. Still, various problems occur while the forensic investigation. In the section given below some of the frequently occurring challenges faced by forensic investigators are explained. Explore all the issues in cyber crime investigation and apply the perfect technique to eliminate them.
Check Out Current Challenges in Digital Forensics Investigation
the development of new technology is to invent things to benefit
mankind. But criminals use technology to achieve their own targets.
Thus, forensic investigators have to go through various challenges &
issues in forensic investigations process to find out the real
culprit behind the crime. Some of the real-world problems faced by
digital forensic investigators are:
1: Hardware Issues
enhancements to fulfil
technological needs is a key constraint.”
while investigating a case, the suspect replaces the hard disk
before it is acquired by the forensic experts. Moreover, the data
has been already transferred from the old hard disk to the new one
using write blockers then forensic investigators would face some
challenges in digital forensic evidence collection from the
unallocated clusters. Additionally, in some cases, the evidence of
the replacement of the hard disk may not be apparent.
the time of carving evidence of communication from a mobile device
that was reset just before acquiring the evidence is also issues
in digital forensics investigation.
In such a situation, only a select backup is reinstalled which
accentuates the issue.
several laptops, the hard disk contains an inbuilt algorithm to
self-erase data on the removal from the machine. It becomes a very
in cyber crime investigation situation to gather
evidence from the hard disk without removing it. Moreover, in modern
SSDs (Solid State Drives), recovery of deleted contents are the big
challenges faced by forensic investigators.
a few cases, the size of hard drives is too big which means the
investigators have to become efficient while examining large volumes
of electronic data. Forensic Examiners also need to be more
selective about devices to be seized for examination.
2: Software Challenges
Cyber Crime Investigation
and PaaS models have altered the structure of computing”
application data is associated with multiple constraints. It can be
due to the natures of the Operating system and application in which
they are defined. For Example, to track the changes made in the
contents of the file one has to compare it with the
previous/subsequent version of the file or with its last modified
timestamp. Now, this task becomes complex challenges in digital
forensic evidence extraction where document manipulation is
certain logs and application information gathered from an operating
system may be helpful in selective investigations. One can
understand better via an example: The Windows 8 operating system
gathers information on a Wi-Fi network accessed and the extent of
data transmitted. This type of information may be helpful in case of
data theft or certain network-intrusion scenarios. However, the
correlation between the event of violation and information collected
from these sources is still being tested on an individual case
challenge of gathering evidence becomes more complex issues
in forensic investigations, with the increase in the
number of mobile chat applications containing features of self-erase
or deletion on the delivery to the intended recipient.
in the devices also proves to a challenge while carving evidence
from them. For example, to gather evidence from a mobile messaging
application such as WhatsApp, one has to decrypt the device. This
comes out to be a challenging problems
in cyber crime investigation.
Challenge 3: Legal Issues in Digital Forensics
privacy and data protection regulations across maturing regulatory
definitions and geographies aspects may lead to complex challenges
in digital forensic evidence gathering. For instance, information
present on the suspect’s system may contain some non-sensitive,
private information. This information may be useful at the time of
the investigation. However, accessing such information may be
considered as a violation in certain countries.
most of the companies believe in BYOD – Bring Your Own Device
policy. The companies allow employees to use their personal mobile
devices for accessing official communication. This become a complex
challenges faced by forensic investigators in gathering evidences
during the investigation process. For example, accessing an email
from webmail using a mobile device and then downloading the
attachments can lead to data theft. Moreover, specific information
on the device on which such type of information was downloaded and
details on which files were downloaded can be difficult to trace in
the current environment.
Additional Issues/ challenges faced by forensic investigators.
a cloud-based environment, there is an increase in the identity
theft and opportunities of credential compromise. As cloud-based
applications permit the users to access data from multiple devices.
Thus, it becomes difficult for forensic investigators to gather
evidence where a user is using two devices to make changes to the
application data or service at the same time. As the major problem
occurs while identifying the source of the changes.
use technology for terrible tasks such as data theft, identity breach
etc. Whereas, development in technology is done to provide benefits
to mankind. Now, to deal with all the digital crimes forensic
investigators make use of different tricks and software to carve
evidence and identify the criminal. Still, there are many challenges
crime investigation which forensic examiner have to
face while dealing with the case.
