What is Computer Forensics?
What are Computers Forensics. Everyday
living has become easier and technologically more advanced than
decades ago. While computers have radically changed the way we
live our lives. It has changed the way we work and the way we
live in our houses. Children to day are sometimes even more
technologically aware than their parents ever were. Mobiles
phones have gotten smaller and laptops have gotten slimmer.
With the launch of the Iphone that used the touch screen
technology it will only be a matter of time when this idea
permeates into other devices and appliances. Unfortunately,
technology also makes it easier for criminals to their dirty
job. However, computer forensics makes sure that technology is
put to lawful use.
Everyone keeps up with the times, even the criminals. The
internet is a public place which makes it vulnerable for fraud.
Criminals often take advantage of unsuspecting victims. Law
enforcement agencies have incorporated computer science in
their investigation process to aid them with computer savvy
criminals.
Computer forensics is basically applying computer science to
assist in the legal process. It entails the technological and
systematic inspection of the contents of a computer system for
evidence. Individuals in this field are called by different
titles such as digital media analyst or computer forensics
investigator. These people scanned a computer thoroughly to
find out if they have used for a civil wrongdoing or criminal
act.
Crime and computers. We have seen a lot
of Hollywood movies about hackers stealing from financial
institutions. We have also seen two parties making their deals
through bank transfers with a bunch of computers. Although
these are not possible in real life, there are other ways that
criminals can use computers. The skills required are more
than just normal data collection and using preservation
techniques. Other definitions include the use of special tools
to meet the Court's criteria and not just a thorough
examination of a computer for potential evidence. This
definition is similar to Electric Evidentiary Recovery or
e-discovery.
Most of the time computer forensic investigators investigate
hard drives, portable data devices and data storage devices.
These devices include USB Drives, Micro Drives and external
Drives.
The first task of the computer forensic investigator is to
find sources of documentary or digital evidence. The next step
would be to preserve the evidence so that it could be analyzed
later on. When dealing with computer systems, important files
or data can be quickly lost.
The investigator should take the necessary test because data
retrieval can be time consuming and costly. The investigator
would then analyze the collected data for potential and
supportive evidence. The final step would be presenting the
findings. The investigator will render his opinion based on the
examination and make a report.
The process of using computer forensics must comply with the
standards of evidence that are acceptable in court. This field
is both technical and legal. The investigator should also have
a complete understanding of the suspect's level of
sophistication. If they don't the suspects are assumed to be
experts.
Investigators then presume that the criminal have installed
a countermeasure to render forensic techniques useless. The
computer will then be shutdown completely to prohibit the
machine from making further modifications to its drives.
Computer technology has changed the way we live, work, and
for others - how to commit crime. Although the internet may
seem like a very convenient place users should always be wary
for seemingly innocent offers.
