It merely slows down the process. Also, one is depended on the persons that are responsible for the system. If any of the persons responsible for the system leaves the organizations, the system cannot be considered secure any more and it must be changed again. Objectives of the Study To increase computer security one should make a cost-benefit analysis before implementation. In this study we wanted establish a system by means of STO that tackles the following four issues in computer security.
Computer security is often inversely propotional to convinience.
The security is gained at a cost of a system performance, use of system resources, ease of use and system management time. Secondly, one of the main reasons today for unauthorised accesses to computer systems is due to the use of publicly available programs that can be used monitoring the network traffic and decrypting vital information for example in passwords files. Ironically, many of these tools are originally designed to increase computer security. A firewall is a combination of software and hardware that limits these interactions to the degree desired. The firewall does not restrict interactions in the local network.
