The PCS working group has been a smashing success and the team members have already formed better inter-department communications. The customer Security Director from the Istanbogus Ministry of Defense has requested a threat briefing explaining the top risks to his new system. As the CISO you have your ideas but would like to get the opinion of the working group members. Describe at least three different categories (human and non-human) of threats from your Unit research. Explain how each category presents risk to information systems. Make a case for the top threat to the missile defense system for each category and give an example of how that threat might be realized in a real compromise of the system. Discuss some of the factors that play into the assessment of system threats. Include at least one research reference and associated in-text citation using APA standards. In your replies to your peers discuss the other described threats and if you feel they are greater or lesser risks to the system.

File account. java (see previous exercise) contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a string representation. note that the constructor for this class creates a random account number. save this class to your directory and study it to see how it works. then write the following additional code: 1. suppose the bank wants to keep track of how many accounts exist. a. declare a private static integer variable numaccounts to hold this value. like all instance and static variables, it will be initialized (to 0, since it’s an int) automatically. b. add code to the constructor to increment this variable every time an account is created. c. add a static method getnumaccounts that returns the total number of accounts. think about why this method should be static - its information is not related to any particular account. d. file testaccounts1.java contains a simple program that creates the specified number of bank accounts then uses the getnumaccounts method to find how many accounts were created. save it to your directory, then use it to test your modified account class.
