Introduction the world today and the ballistic use of information systems networks has made several countries progressively interconnected and mostly in technologically advanced countries, computer network perform a key role in how companies carry out business, how services are provided by government to its citizens and how different individual communicate and trade important information (Downing, 2005). this exchange of information through the use of computer/internet brings about what is known as cybercrime Speer (2005) defines cybercrime as activities in which computers, telephones and other technological devices are used for illegal objectives such as theft, fraud, electronic defacement and breach into computer system and networks. however, security managers need to have a full knowledge of cybercrime because it is the rising mode of crime and the least reported (Phair, 2007).

Security managers and cybercrime security managers need to understand that cybercrime has become a profanity in the society which affects everyone both nationally and internationally, individuals, institution, companies as well as the government and this is however a rumination of the growth of criminals practices (Helle et al, 2012). there are various characteristics of cybercrime that need to be understood by security managers and they include: it is usually a distinct/singular event from the victim's perspective, it is often facilitated by crime-ware program introduction and its introduction may not ineludibly be facilitated by weakness (Gordon et al, 2006). according to Speer (2000) there are four major component of cybercrime which security managers need to examine and address,they include:

the location of the offender the victims the offender eliminating the threats

challenges of cybercrime various countries have approached the challenges of cybercrime in different ways but it still remains a crucial challenge for so many societies worldwide because the danger of cybercrime is not just a worry for information societies which are deeply reliant on information technology accessibility (Gercke, 2009). since countries fight cybercrime in different ways, (Hang et al, 2002) gave four various suggestion on how to fight cybercrime to lawmakers, government, international organisation and researchers, they are: update existing law enhance specialised task forces utilize civil sources promote cybercrime research however, there are reasons why cybercrime criminal get away with the crime and even with technical abilities, the crime still spreads because people react to the threat slowly with low level of public knowledge about the risks and most companies do not want publicity ( Wall, 2008).
