lack o lified people to serve as researchers and practitioners. Not merely the result of the general
tech shortage, the very nature of digital forensics makes staffing significantly harder than in
other disciplines. Because the field's mission is to understand any data that might be stored we
need individuals who have knowledge of both current and past computer systems, applications,
and data formats. We need generalists in a technological society that increasingly rewards
experts and specialization for opportunities to break down forensic problems into modular pieces
so that experts in related fields can make meaningful One way to address this training problem is
to look contributions. I believe that another approach is to show how the underlying principles

2. and current tools of digital forensics can be widely applied throughout our society. This
relevancy should increase research into tools and hopefully expand the user base of the software
Many of the tools of digital forensics can be used for privacy auditing. Instead of finding
personal information that might be relevant to a case, businesses and individuals can use the
tools to look for the inappropriate presence of personal information left behind because of bugs
or oversight. Likewise, individuals can use programs such as file carvers to recover photographs
that have been accidentally deleted from digital cameras. More generally, as our cars, street
signs, communication systems, electrical networks, buildings, and even social interactions are
increasingly computerized, digital forensics is lik to be one of the on ways of understanding
these systems when the misbehave-or when the are subverted
Solution
Forensics is changing in the digital age,and the legal systems is still catching up when it comes to
properly employing digital evidence
Broadly speaking ,digital evidence in information found on a wide range of electronic devices
that is useful in court because of this probationers value it's like the digital equivalent of a
fingerprint or a muddy boot
However digital evidence tendered in court often fails to meet the same high standards expected
of more established forensics practices,particularly in ensuring the evidence is what it purpose to
be
TECHNOLOGY CHANGES EVIDENCE:-
This is the sot the first time that technology has impacted the way evidence is gathered and
presented in courts .And it's not the first time that there have been problems in the way new
evidence is used
You might remember the case of the death of AZaria Chamberian at Ayers Rock more than 30
years ago forensics played a key role in the conviction of Lindy chamberian in 1982 however her
conviction was later reversed in 1988 following closer security of the evidence
Subsequent coronial inquests ,a court case featuring controversial DNA forensics evidence and
the subsequent Australian Royal commission into azaria's death resulted in a fundamental
reconsideration of Australian forensic practices
CYBER EVIDENCE:- it is increasingly common for criminal trails to relay on digital evidence
and regrettably ,it is not uncommon for innocents to be convinced and guilty people acquitted
because of digital evidence
There are several reasons for this ,firstly the evidence might be compelling at first glance but it
could be misleading the defendant may also have limited financial resources to rebut the

3. evidence.The defence lawyers might also misread the evidence plea-bargaining offers can also
lessen sentences conversely other investigations may not get to trail because of the complexity or
incompleteness of the evidence
Worryingly some defendants are pleading guilty based on what appears to be overwhelming
hearsay digital evidence without robust defence rebuttal in these cases,the defence lawyer -
whose job is to analyses the evidence may simply not understand it this is why external digital
forensics consultants can be so important
GETTING TO RIGHT:- digital forensics is still in its infancy and it is more of an art form
lacking broad scientific standards to supports it use as evidence there is a call among researchers
to test and trail before forensics practices and forensic tool this is expecially important due to the
increasing size of data storage on some personal computing devices let alone cloud and network
storage which presents greater recovery and jurisdictional challenges to practitioners
