Unauthorized Access to a Computer System and Defensible Networks - Assignment Example

If someone is involved in criminal operations and security agents feel that getting into his system without his permission may be the way to get evidence against him then that will be ethical. Also, if a company suspects something wrong is going on with its network then it may be ethical to investigate the network connected to its network ( Bejtlich, 2003).

            Ethical hacking is a good practice as it helps companies to enhance the security of their computer system. Without a proper audit of the computer system, no real computer security exist. However, the certificate must be issued with a lot of caution and the authorized hackers should testify on oath.  

Question 2

            A Defensive Network Architecture is an information planning for the network security system which is well maintained and controlled and very closely monitored to identify weaknesses in the system (McClure et al., 1999). This architecture must be up to date to resist current forms of attack. Defensive network architecture is important mostly for large organizations since it helps to monitor their networks. Network monitoring also assists in evaluating environmental changes (McClure et al., 1999). For example, when there is an increase or decrease in traffic and assets which are currently maintained and secured. Our organization has an architecture in place that they use to control and monitor their security system. Since it is an organization that deals with confidential documents, this helps to secure its data.

            In conclusion, a defensible network has become so important that on 14th March 2014, Scott Air Force Base III marked a major progression when they signed a Department of Defense's Joint Information Environment (Shelly, 2014).
