6. Definitions/Semantics
“the use of scientifically derived and proven methods towards the preservation, collection, validation, identification, analysis, interpretation, documentation and presentation of digital evidence derived from digital source for the purpose of facilitating or furthering the reconstruction of events found to be criminal or helping to anticipate unauthorized actions shown to be disruptive to planned operations.” (DFRWS, 2001)
Digital Forensic also known as computer and network forensic is considered as the application of science to the identification, collection, examination and analysis of data (NIST, 2006)
Utilization of computers to solve computer related vices.

7. Introduction; Time-line of activities.
Early years (1970s-1990s)
Hardware, software, and application diversity
A proliferation of data file formats
Heavy reliance on time-sharing and centralized computing facilities
Absence of formal process, tools, and training
„Golden years“
(1990s-2000s)
The widespread use of Microsoft Windows, and specifically Windows XP
Relatively few file formats of forensic interest
Examinations largely confined to a single computer system belonging to the subject of the investigation
Storage devices equipped with standard interfaces (IDE/ ATA)
Era of crisis
(2010s-...)
Growing size of storage devices
Increasing prevalence of embedded flash storage
Proliferation of hardware interfaces
Proliferation of operating systems and file formats
Pervasive encryption
Use of the “cloud” for remote processing and storage, splitting a single data structure into elements.
Intercontinental hacking of identity eg recent alleged Chinses hacking of US.

8. Uses of digital forensic
Digital evidence can be used for:
Internal disciplinary hearing
admissible in a court of law
supporting data for internal incident reports
Assist in furthering other investigation
Research and development
Data
Profiling of criminals

9. Common Digital Vices Phising/Spoofing Blackmail/Extortion
Accessing Stored Communications
Sports Betting
Non-Delivery of Merchandise
Electronic Harassment
Child Pornography
Prostitution
Drug Trafficking
Criminal Copyright Infringement
Terrorist recruitments by Militants.
Website Cloning
Etc.etc

10. Nigeria Episode
The term “cybercrime” is now globally known and associated with Nigeria and referred to as “419” scamming in Nigeria.
This began in Nigeria with the realization of the full potentials of the internet, the youths in the country discovered different ways of using the internet to carry out different types of criminal activities.
The incidence of cybercrime can be said to be on increase in the country due to the lack of security awareness and under reportage of the crime (Okeshola and Adeta, 2013).
Nigerian Cyber criminals are daily devising new ways of perpetrating this form of crime and the existing methods of tracking these criminals are no longer suitable to deal with new tricks (Ibikunle and Eweniyi, 2013).
Internet world stats, showed in November 2007, Nigeria having the highest number of internet users in Africa and computer crime and cyber survey conducted indicated the country as the most fraudulent country in Africa.
The same survey also ranked the Nigeria third among others identified with cyber fraud and computer crime in the world.
The people that fall victim to this crime are naïve and gullible at the prospects incited by these fraudsters

11. Legislation Dilemma
Cybercrimes and white collar crimes are particularly lucrative because they are generally non- violent crimes that yield high profits and have relatively low risk of capture and if caught and convicted usually results in relatively short prison sentences.
Judges and Juries view cybercriminals as intelligent, misguided individuals rather than as cyber thugs that they are.
The internet is a major problem of legal investigators because of issues like jurisdiction. It is possible for a criminal in one country to perpetrate a crime against a person in another country and all the while using a server from a third world country. Law varies from country to country and a felony in one country might not be illegal in another country.
The use of the internet as totally changed crime scene investigation due to his dynamic mode of operation. The internet used to perpetrate a crime today might be different from the one used the next day.
Internet access can be gained from different computers in an industrialized country where criminals can gain access from a different computer at a different location every time they logon, while it may be easy to prove that a particular computer was used to access a given server at a given date and time, it may be very difficult to prove whose finger print id on the keyboard (Kesseier, 2005).

13. Financial Cyber-crime in Nigeria
Reports of Cyber Crime has increased over the years, one of the most frequently attacked organizations in Nigeria is the Inter-switch, which has one of the highest customer base electronic transaction in Nigeria (Ahmed, 2008).
Nigeria Deposit Insurance Corporation (NDIC) revealed in their annual report and statement of account that underhand deals by bank staff and other attempt of fraud cases resulted to about ₦10.1 billion and actual loss of about ₦2.76 billion in (Ahmed, 2008).
A report from the Economic and Financial Crime Commission of Nigeria issued a report in 2007 of how a retired civil servant with two other defrauded a Garman citizen named Klaus Wagner a sum of $1,714,080 USD through the internet and during this period Nigeria was ranked the third in terms of online crime (Okeshola, 2013).
According to Ribadu (2007), the prominent forms of cybercrime in Nigeria include Website cloning, false representations, identity thief, e-commerce fraud, credit card theft, fraudulent electronic mails, internet banking and website defacing.

14. Our Response so far
On the 5th of February, 2014, the President of Nigeria ‘Goodluck Jonathan’ introduced a cybercrime bill, 2013 in the National Assembly.
In the bill, the FG seeks Power to Intercept SMC, , BBM’s and Fax. The objective of the bill includes among other goals, protecting the country’s national information structure and establishing an integrated legal, regulatory and institutional framework to deal with cybercrimes (Daily TRUST, 2014).
As at now there is absence of appropriate laws to guarantee the legality of online transaction, which as a result continues create fear in the mind of users and the potential online users.
The Director of Communications in the office of the National Security Adviser, at the presentation of Public Key Infrastructure (PKI) Blueprint for Nigeria, spoke about the increasing dependency on computer systems and network in Nigeria by the Government and citizens to provide critical services.
He pointed out that his office has put measures in place to protect all critical information infrastructures and secure computer systems and network in Nigeria, his mitigation measures includes the establishment of a fully functional digital forensic laboratory in the office of NSA, other measures put in place is the establishment of a National Computer Emergency Response Team Center for The monitoring, detection and analysis of the activities in the cyberspace (Emejor, 2013).
