Identify the incorrect statement:

Question

Accepted Answer

Correct answer: D — Concept. A “find the incorrect statement” item is a truth-value classification task: every option is an independent claim that must be tested on its own against the standard body of knowledge, and exactly one of them conflicts with it. Three standard results in electronic commerce settle this item. Grouping of e-commerce attacks. Standard electronic-commerce texts group attacks on e-commerce systems by the means used to carry them out, into two major categories: non-technical attacks, which use deception so that people disclose information or take unsafe actions (phishing, social engineering), and technical attacks, which are executed with software and systems expertise (DoS and DDoS floods, brute-force attempts, malicious code). Business strategy sets the warehouse agenda. A data warehouse exists to answer the questions an enterprise has committed to, so the overall business strategy is what fixes the warehouse's subject areas, metrics and grain, and the data warehousing strategy is derived from it. Classical discipline still applies on the web. E-commerce adds new sources (web-server logs, clickstream and session data) and a new server tier, but the warehouse over them is still built with proven classical warehousing practice — conformed dimensions, a declared fact grain and scheduled loads — rather than with an ad-hoc method. Application. Testing each statement on its own against those results: Statement Status against the standard body of knowledge The overall strategy drives the E-Commerce data warehousing strategy. Agrees with standard practice: the business strategy is what sets the questions the warehouse must answer. Data warehousing in an E-Commerce environment should be done in a classical manner. Agrees with standard practice: the new web sources are absorbed by classical dimensional warehousing discipline. E-Commerce opens up an entirely new world of web server. Agrees with standard practice: e-commerce adds a web-server tier that is both a service point and a data source. E-Commerce security threats can be grouped into three major categories. Conflicts with standard practice: the accepted grouping has two major categories, non-technical and technical. Cross-check. The discriminator is the count. The accepted grouping of e-commerce attacks has two major categories, not three, so exactly one of the four claims conflicts with the standard body of knowledge while the other three restate it. The official UGC NET June 2012 answer key for Computer Science and Applications, Paper II (subject code 87, question 42) marks the same statement as the incorrect one. Result. The incorrect statement is “E-Commerce security threats can be grouped into three major categories.”
