Java is case-sensitive, meaning that Uppercase characters are different the Lowercased character giving the user more options in naming. Java keywords for variable names are reserved, unlike Visual Basic where it was bad practice to use keywords. (Beginning JAVA, n.d.) In the great world of programming, it is important to remember what language one is working with to ensure that the proper naming rule is being applied. There is nothing worse than writing a whole program using the wrong naming rules. References Beginning JAVA.

Explain the approach we have taken to educate broad users will differ from the specialized education needed for higher-level security (i.e. securing the use of an administrative account). IMPLEMENTATION To properly administer the Transnational Railways Windows domains and networks, we will implement Role Based Access Controls (RBAC). AGUDLP (for "account, global, universal, domain local, permission") and AGLP (for "account, global, local, permission") summarize similar RBAC implementation schemes in Active Directory and in Windows NT, respectively. This is a multi-domain environment connected by expensive WAN links or VPN connections, so global catalog servers will be used to cache certain directory object classes and attribute types in order to reduce costly or slow inter-domain directory lookups.

Case Study For any business ping sweeps and port scans could be a huge security threat if they continue unnoticed. Ping sweeps are performed to find end points on a network. Then a port scan is performed to find an open door into that particular end point or end points. After that anyone can find all kinds of utilities on the internet to exploit these open doors on systems and gain access to important and confidential files on the network. It’s imperative that we not only protect against these types of activities on the network, but that we also conduct them ourselves.
