Information Systems Dissertation - Computers Security Business

While attacks on computers by outside intruders are more publicized, attacks perpetrated by insiders are very common and often more damaging. Insiders represent the greatest threat to computer security because they understand their organization's business and how their computer systems work. They have both the confidentiality and access to perform these attacks. An inside attacker will have a higher probability of successfully breaking into the system and extracting critical information. The insiders also represent the greatest challenge to securing the company network because they are authorized a level of access to the file system and granted a degree of trust.

Information Systems Dissertation - Intrusion Prevention Security

Intrusion detection systems (IDS) were developed in 1990’s, when the network hackers and worms appeared, initially for the identification and reporting of such attacks. The intrusion detection systems didn’t have the ability to stop such attacks rather than detecting and reporting to the network personnel. The Intrusion Prevention Systems got both characteristics i.e. threat detection and prevention. The detection process analyzes the events for any possible threats while the intrusion prevention stops the detected possible threats and reports the network administrator.

A computer network is a connection of two or more computers in order to share resources and data. These shared resources can include devices like printers and other resources like electronic mail, internet access, and file sharing. A computer network can also be seen as a collection of Personal computers and other related devices which are connected together, either with cables or wirelessly, so that they can share information and communicate with one another. Computer networks vary in size. Some networks are needed for areas within a single office, while others are vast or even span the globe.
