- Description: M.Comm. , The problem of establishing and controlling remote access to corporate networks has become one of the most difficult issues facing network administrators and information security professionals (Tipton & Krause (b), 2001:99). As the connection devices become more powerful and less expensive, more and more personally owned devices make their way to the connected edge of the network. The rise of the Internet as an accepted vehicle for business use has dramatically increased the points of entry to the corporate network. As employees and third parties gain mobility through the use of laptops, smart phones and Personal Digital Assistants (PDAs), the threat to organisational security grows (Cartwright, 2001). There are three main reasons why remote access connections are often insecure: Lack of awareness regarding security risks associated with remote access; Protecting a remote access connection is a complex task which is unlikely to be done well unless a methodical approach is taken; and Remote locations are not under the direct control of the organisation and are inherently insecure (Information Security Forum (a), 1999). The purpose of this short dissertation is to: Provide an overview of remote access, including concepts and definitions; Identify the risks associated with remote access to corporate networks; Identify possible controls to mitigate these risks; and highlight possible future trends regarding remote access.

- Description: M.Comm. , Soon after the introduction of the automobile in the early 201 h century, the number of crimes doubled. The projection for the future is that the computer might produce an impact for law and law enforcement greater than that created by the invention of the motor car. Experts agree that computer crime will be the single greatest crime generator of the 21st century (Association of Certified Fraud Examiners, 1999: 1 ). Although the advances in technology have an impact on all walks of life, this short dissertation will focus on the effects thereof on crime in the workplace. Electronic commerce touches all major aspects of economic life and presents a series of complex issues. It involves the integration of many elements of technology, infrastructure, business operation and public policy. All these elements need to operate together as smoothly as possible to yield the maximum benefits to the public (South Africa, 2000), and all other stakeholders. Today very few business organisations and government departments have business information systems that are not computer based. More and more organisations connect to the Internet to conduct their business and/or to provide a variety of services. Computer-based crimes have now become a part of the general problem of white-collar crime. The problem of fraud, or white-collar crime, is serious. Statistics have shown that corporate losses due to fraud and embezzlement exceed total losses due to bribery, burglary and shoplifting by a wide margin (Bodnar & Hopwood 1998:218). The introduction of networks, and specifically the Internet, has exacerbated this problem. Pincott (2001 :76) found that fraud costs firms an estimated GBP 40 million a day and is a factor in 30 per cent of all insolvencies. As the complexity and global pervasiveness of fraud escalates, a new survey concludes that managements are failing both to implement preventive measures and to address the issue once an offence has occurred (Anon., 2000:11}. There is a lack of common understanding of computer-related crimes and more research into the field is required.
