Week-14 Research Assignment
By
Nagendra Babu Chinnam
Digital forensics is the process of investigating by accumulating
evidence from digital equipment like computers, networks,
4. cloud, hard drive, and any endpoint
system connected to the technological infrastructure. Digital
forensics involves retrieving evidence by preserving or
recording the digital devices' state, analyzing
them, and reporting the information recovered. In instances of
cyber-attack crimes, a digital forensics examiner analyzes the
digital attack to retrieve evidence to help
track the attackers. In today’s world, with more than 95% of
people having cellphones, the data existence is staggering. The
mobile phones involved in the investiga-
tion and devices like laptops, desktops, smart watches, and all
other devices that fall under the internet are capable of data
exchange. Data forensics has been
particularly stressed by the emergence of higher sophisticated
devices (Kävrestad, 2018). Digital forensic methods are used to
solve the crime by law enforcers
and investigators every day. For example, there was this cas e in
the United Kingdom back in 2009 of a particular guy, Krenar
Lusha, who was an illegal immigrant to
the UK. He was arrested based on his internet search engine
pattern. He was found guilty due to the help of digital forensics.
Once the computer forensics
experts investigated his laptop, they discovered that he had
downloaded a manual of 4300GM that contained information to
make search belts and explosives. This
opened up the case, giving them the warrant for further
investigation to search his house, where they found 71.8liters of
petrol, potassium nitrate, and a live shotgun
cartridge. Digital forensics also showed other evidence that he
had used his laptop to message people via MSN, where he
described himself as a terrorist and a
5. sniper. In the messages, he portrayed himself as someone who
hated Jewish and American people and wanted to see them dead.
All this information was re-
trieved from his laptop using digital forensics and used as
digital evidence in court (Roussev, 2016). Several criminal
cases have used digital evidence to uncover hid-
den scams. In most criminal cases, whenever there is not enough
evidence gathered from all the sources acquired, digital
forensics will often provide adequate evid-
ence to convict the person. Most of these digital devices that we
use can store 99%of the information that we feed them, and in
case of a criminal investigation, they
come in handy. Digital forensics is an effective method to solve
crimes commonly used today by investigators (Husain & Khan,
2019).
