Describe some illegal reconnaissance activities.
What will be an ideal response?
There are a number of plainly illegal reconnaissance techniques. Developing a "front" company and acting as a representative of that company, specifically for the purpose of robbing or defrauding the target company, is probably illegal. Furthermore, being expensive and time consuming, this is probably reserved for the professional intel agencies. Stealing garbage is illegal in many locales. Entering a home or office to look for information is also illegal, but this often goes undetected as no valuables are being removed. Dropping a keylogger-a tool that records users' keystrokes-on a vulnerable machine is illegal. Leaving a sniffer, which can intercept and read data packets, on a network is illegal.

1) A loop control variable is a variable whose value controls the data type of the repetition condition. 2) A counting loop is a data input loop that exits on entry of a predetermined value. 3) A sentinel loop is a repetition structure that executes a predetermined number of times and is controlled by a counter. 4)Assuming the following declarations, ``` int data; ifstream infile ("program.txt", ios::in); ``` as long as the extraction operation ``` infile >> data; ``` finds values in program.txt that are the expected data type for data, the value of ``` infile.fail() ``` will be false. 5) The body of a do-while loop is always executed at least one time.
Develop a C# app that will determine whether any of several de- partment-store customers has exceeded the credit limit on a charge account. For each customer, the following facts are available:
a) account number, b) balance at the beginning of the month, c) total of all items charged by the customer this month, d) total of all credits applied to the customer’s account this month and e) allowed credit limit. The app should input all these facts as integers, calculate the new balance (= beginning balance + charges – credits), display the new balance and determine whether the new balance exceeds the cus- tomer’s credit limit. For those whose credit limit is exceeded, the app should display the message "Credit limit exceeded". Use sentinel-controlled iteration to obtain the data for each account.
