Section: Protection of Information Assets
Explanation:
In traffic analysis, which is a passive attack, an intruder determines the nature of the traffic flow between defined hosts and through an analysis of session length, frequency and message length, and the intruder is able to guess the type of communication taking place. This typically is used when messages are encrypted and eavesdropping would not yield any meaningful results, in eavesdropping, which also is a passive attack, the intruder gathers the information flowing through the network with the intent of acquiring and releasing message contents for personal analysis or for third parties. Spoofing and masquerading are active attacks, in spoofing, a user receives an e-mail that appears to have originated from one source when it actually was sent from another source. In masquerading, the intruder presents an identity other than the original identity.

Determining time and resource requirements for an application-development project is often the most difficult part of initial efforts in application development.

An integer overflow occurs when an arithmetic operation attempts to create a numeric value that is larger than can be represented within the available storage space. On some processors the result saturates - once the maximum value is reached attempts to make it larger simply return the maximum result.
